EXPANSION OF THE UNIVERSE

"You are the Creator of your own desitiny"
(D.P)


Intialy we have to understand some fundamentally phenomenon

It starts from the curious people.
German mathematician Theodor Franz Eduard Kaluza suggested very bold idea 
He proposed our universe might not have only three dimensions but more than three dimensions. There might be some additional dimension but for some reason we don't yet see. When someone made a bold idea people won't believe in that & nothing to do with the world around us.
This particular idea however although whether we don't know right or wrong, but in the future Experiment may tell us right or wrong. This idea made major effect on physics from last century. 
I like tell you about that extra dimensions let's go to the 1907 when Einstein discovered the Theory of relatively and try to understand in terms of gravity.
But many people says that Newton has already provided the theory on gravity and that explain the motion of planets, motion of everything around us. But Einstein knows that Newton had left something behind.But Newton knows that it's theory is correct but can't explain each and everything . Just like how does the sun attracted earth how?.
Here comes Einstein tell us how gravity works, Einstein tells us that space is flat as no matter present in there,if matter present in the environment such as the sun causes the fabric of space to work, and that communicate with the force of gravity.

According to these ideas moon is orbiting around the earth,in valley and in contour.
By the virtue of there present,so this the new idea how gravity actually works .This idea was tested in 1919 through astronomical observation it really works and describes a data and this gained Einstein. Prominent around the world. This what Theodor Franz Eduard Kaluza ( German mathematician) was thinking that like he & Einstein searching For unified Theory .
That one theory might be able to describe nature of all forces by one set of ideas , one set of principle,one master equation.

Eduard Kaluza was thinking that Einstein been able to understand the gravity in terms of curves in space, infact space & time more precise. May I can play the same game with other known force, which was that time known as the electro magnetic force in terms of curves. So he proposed that there are more dimensions if I need to describe more forces. So he imagined that there are 4 dimensions not 3 .
So when he driveved the equation for four dimensions instead of 3 dimensions he found one more extra equation. So he found the equation that scientist used to describe EM force . So he was very happy that he found unified theory. He took his Theory very seriously. So question arises from his Theory that if there is extra dimension why we can't see them, & does this theory work in detail in practicality. First question was answered in 1926 by mathematician he suggested that dimensions might come in two verities there might be be easy to see dimensions there might be very small dimensions we can't see, it is present around us but we can't See, If you go inside you will find amazing things that which explains that dimensions exist .
So this is the explanation that how the additional dimension exist .
This was all about extra dimensions let understand the from the beginning.

Scientists believe that our universe began with one enormous explosion of energy and light, which we now call the Big Bang. This was the singular start to everything that exists. The beginning of the universe, the start of space, and even the initial start of time itself.

In the late 1920's, astronomer Edwin Hubble saw through his telescope that galaxies (some millions of light years away) were hurtling away from each other at fantastic speeds. This was not caused by some force thrusting them away from each other. Rather, they were still moving as a result of a primeval explosion, all from one point of origin.
temperature of the universe was about a hundred thousands million (1011) degrees Centigrade. This is much hotter than in the center of even the hottest star, so hot, in fact, that none of the components of ordinary matter, molecules, or atoms, or even the nuclei of atoms, could have held together." He goes on, "The universe was filled with light."

Let's understand deeply some phenomenon

that there are all sorts of different lines of evidence that point to our 13.8 billion year age, similar to how there are so many Independent things show the dark matter and one is to think about the fact that our Universe is expanding and cooling today, and to recognize that it was therefore hotter and denser in the past. If we go back, to earlier and earlier times, we’d find that as the volume of the Universe was smaller, all the matter in it was not only closer together, but that the wavelengths of all the individual photons (particles of light) in it were shorter, as the Universe’s expansion has lengthened them to be as long as they are today.

Since a photon’s wavelength defines its energy and temperature, a shorter-wavelength photon is more energetic and higher in temperature. As we go back farther and farther in time, the temperature goes up and up, until at some point, we reach the earliest stages of the hot Big Bang.If we were to extrapolate “infinitely” far back, we’d reach a singularity, where physics breaks down. With our modern understanding of the very early UNIVERSE and that inflationary state was of an indeterminate duration.

So when we speak of “the age of the Universe,” we’re talking about how much time has past since the Universe could first be described by the hot Big Bang until the present day.
if we can measure how the Universe is expanding today and how it has expanded throughout its entire history, we can know exactly what all the different components are that make it up.
From direct measurements of the brightness and distances of objects in the Universe such as stars, galaxies and supernovae, allowing us to construct the cosmic distance ladder.Universe that is made up, today, of 68% dark energy, 27% dark matter, 4.9% normal matter, about 0.1% neutrinos, about 0.01% radiation, and pretty much nothing else.

Let's understand some factors form which we can determine the age of the universe
The age of the universe must be more than the present particles present in Earth,

Let's say age of the universe is equal to the

Age_universe =Age_earth + Expansion_rate

This Expansion rate is at the time of big bang .

The age of the Earth is approximately 4.54 ± 0.05 billion years.
Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billions years .
So the age of Earth is included in the expansion of UNIVERSE.
Hypothetically age when the earth is formed is
(Expansion rate of universe - Age of the Earth)
It is than approximately 9.26±.05 billion years.

I love to tell you that something is different according to me.
Let's go from the intialy when there is a empty space, at intialy there was only wave particles which do not have any kind of attraction all was in state of rest only waves are present at there after billions of years these waves are get into the motion but according to it they never intersect to each other, all was in the state of motion in a fixed path this motion enhance increasingly, the motion was over million years of Time, the waves particles get some fundamentally change in the nature some waves becomes attractive and some are repulsive due to this phenomenon the cosmic wave is increasing constantly, and due to this there was not only the circular motion there was elliptical and dumble shape type MOTION was develop. This motion of the wave particles genrate energy with some amount of energy but after the interval of time the vibration and energy becomes more and more now the cosmic waves is in the wider range and rate is increasing constantly, some of the wave particles are very nearly to each other that they can concide to each other, due to this some of the properties of wave get interchange with each other and have fundamentally effect on the wave particles.
This cosmic wave get increased and they star to move in particular random motion in particular direction.

So there was not a single cosmic ring there was more than cosmic ring formation taken place and when the boundation force was stronger in the ring.
Some of the important phenomena taken place that these ring have explosion taken place when the rate of energy exceed the barriers of the cosmic ring the large explosion is taken place that is known as "Big Bang"

there was not a single "Big Bang"
There was more Big Bang at a same time due to the cosmic wave blow in the empty space and it unbalanced the nature of all forces, after that the explosion of cosmic ring taken place most of them at the same time some of them after some time due to they are small in size and get threshold energy for start the cosmic explosion.

This cosmic explosion is known as Big Bang (according to me ).
The big bang produces everything in the empty space it forms galaxies and universe.
All the bodies which are converted into the mass form all the bodies was hot body with a higher temperature the bodies which are larger in size have more magnetic field and gravitational pull towards the smaller bodies.the bodies which are smaller in size was also have some Magnetism but due to large bodies all small bodies revolve around the large bodies due Magnetic attraction and gravitational pull so that the have lost there temperature and over the long interval of time they become the planets and hot bodies remain as Sun. Most important thing is the body which is large in size will lost its energy more than small bodies. This is because our sun has more life than other sun ( stars) .

We know that our form of life is exist because of 1AU = 149642000km
For the other solar system this distance won't be same but must be in the RATIO,
This absolutely correct but I have some thing different explaination that is in the form of dark energy, those galaxies will have more dark energy will be more stable and have long life but those have less will falls back according to the dark energy the dimensions can be different in the other galaxies so distance doesn't matter at all ..
Dark energy maters ...

Who rushing away all the galaxies from each other and why expansion is not slowing down, we know that EXPANSION is going on at increasing rate !

Now let's go to the nineties when the astronomer they are inspired by this reasonings to measure the to rate at which the expansion has been slowing and they did this by observation of nemrues different galaxies how the expansion rate is changing with time , the surprise is that , they found that expansion is not slowing down instead they found it's speeding up faster and faster. Now you want to know why what pushing on it . What Force to rush away all galaxies to each other. Solution of this question comes from the idea of Einstein, that we use gravity as pull object together but Einstein general theory of relativity Gravity can also push things apart . According to the Einstein maths if space is uniformlly filled with invisible energy sort of like a uniform invisible mist then the gravity generated by that mist would be repulsive, repulsive gravity. Which is just we need to explain the observation because the repulsive gravity of an invisible energy in space we know called it dark energy it is the somky form it is the repulsive gravity causes push each galaxy into other so speed is not slowing down . When they try to find the amount of dark energy they found a very small value. .

Now let think this again by the string theory as in the last article I told you about string theory . If you examine the ball you will find molecules then atoms , subatomic particles,
if you go more inside you will find something special in that little tiny vibrating string just like a string in guitar they vibrates different patterns producing different musical notes, when these strings vibrates they produce different particles electron , proton, quarks, nuetrino all other particles they all are rise by vibrating string. In string theory we know extra dimensions of space. Usually we know about 3-dimension but string theory explain that there are additional dimension with a small size even we can not detected them. In string theory vibration determines everything most importantly amount of dark energy would be determined by the shape of extra dimensions if we knew the shape of extra dimensions we can calculate dark energy. We don't know the shape of extra dimensions . Some taking us to an idea of string theory of multiverse. 
May be each of these shapes are really with different dimensions means there are many universe each with different shapes of this extra dimensions
If there are other universes and if those universes each have different shapes with a extra dimensions then the physical features of these universe will be different and in particular and amount of dark energy in each universe will be different. Very important thing is that why we are finding dark energy in the universe instead of other things. Solution is that those universe have much more dark energy than ours whenever matter try to clump into galaxies the repulsive push off the dark energy so strong that it makes everything apart . And those universes have less amount of dark energy they will collapse back on them so quickly and galaxy won't form . Without galaxies no stars, no sun, no planets no chance to existence of our form of life to exist on those universes. So we are finding dark energy because our universe has provide us our form of life with particular dark energy. And after that idea of multiverse is strong. Here comes to big bang theory everyone knows about it but there was not a single bang many big bang taken place
simultaneously each giving rise it's separate universe with our universe was the one of them like a bubble so there was form many universes . So idea of string theory is that each of the universe have extra dimensions and extra dimensions yields different physical properties and features. so in our universe the amount of dark energy is sufficient for our form of life so as for other universes it would be different. So how we detect the other universes according to this theory when two universes collide with each other they will produce solar patterns .. in we can observe the multiverse.Our universe is not static space is expanding and expanding is spending up. And there might be other universes so in the future as expansion is going on each galaxy will rush away from us so we will only have black sky.

There might be several things which might be different from everything and I could be wrong but it's my imagination that I m explaining fundamental things. I have reads books before posting this article. But many more conclusion is given by D.P

Can we create an Artificial Earth!


If humans are going to live in an off-world habitat, then it must have the things we've evolved to depend on here on Earth: the right temperature range, breathable air, specific gravity, day-night cycles, and plenty more. But rather than gussying up a spinning, tin can space station, wouldn't it make more sense to re-create our planet by building an artificial world?
A STAR  is a huge , massive body of luminescent matter radiating enormous amount of energy every second . Earth was born some 4.6 billion years ago as an interstellar cloud of gas and dust coalesced to form the Sun and rest of the solar system.
The mean distance between sun and earth is 149,642,000 km . This is known as one  astronomical unit .

Distance from sun in astronomical unit are 
Mercury        0.39 AU
Venus.          0.71 AU
Earth.           1.00 AU
Mars.           1.52 AU
Jupiter.        5.20 AU
Saturn.        9.54 AU
Uranus.       19.20 AU
Neptune.     30.10 AU

Earth makes orbital motion around the sun at a speed of 29.76 km/s
and complete one revolution
in 365.25 days or one year.
Repulsive gravity of an invisible energy in space we know called it dark energy.
how we can create an artificial Earth!

Have you ever wondered why satellites appear to be covered in gold or silver foil?


While they may seem like they are draped in precious metal, it’s usually not gold at all… or even foil! It is actually a material called multi-layer insulation, or MLI.

MLI consists of lightweight reflective films assembled into thin layers that range in thickness. These layers are usually made of polyimide or polyester films (types of plastics) coated with very thin layers of aluminum. The exact composition depends on where the satellite will orbit, what the insulation will be protecting and how much sunlight it will be exposed to.

The gold and silver colored sheets you see are often a single layer of aluminized polyimide with the silver aluminum side facing in. The yellowish-gold color of the polyimide on the outside gives the satellite the appearance of being wrapped in gold.

Close-up of Multi-layer insulation from a satellite. Credit: AerospaceEd.org
Multi-layer insulation is used on satellites primarily for thermal control and protects the delicate on-board instruments from the extreme temperatures of space. Depending on its orbit, a satellite can experience temperatures from below -200°F to well above 300°F, sometimes at the same time! Not to mention the high temperatures the onboard instruments can produce.

While MLI does not insulate a spacecraft from heat conduction or convection very well, this doesn’t particularly matter in the near-vacuum of space. With no air around, radiation is the dominate form of heat transfer. MLI is designed to reflect solar radiation back into space, keeping the instruments cool enough to operate while in sunlight. It also maintains internal temperatures by keeping heat in, protecting the instruments from the extreme cold experienced when the spacecraft moves through Earth’s (or its own) shadow.
MLI can also provide a layer of defense against dust impacts, protecting delicate internal instruments and sensors from tiny particles of space debris.

Although sheets of gold are not used to cover entire satellite bodies, real gold is in fact used on some satellite components. From vapor-deposited gold taping to gold coating, gold is used because of its multiple benefits in outer space. Gold helps protect against corrosion from ultraviolet light and x-rays and acts as a reliable and long lasting electrical contact in onboard electronics.
Gold is also used by NASA in the construction of spacesuits. Because of its excellent ability to reflect infrared light while letting in visible light, astronauts’ visors have a thin layer of gold on them to protect their eyes from unfiltered sunlight.

Bermuda Triangle mystery SOLVED

Bermuda Triangle mystery SOLVED: There are scientific reasons behind the disappearances of sea and water vessels.


This is one the favorite questions among the students. Many asked the same question reason behind the Bermuda triangle. I give them a various reasons behind them one them is scientific evidence .


scientist believes he has solved the mystery behind the Bermuda Triangle, the notoriously famous part of the Atlantic that has claimed at least 1,000 lives in the last century, and where dozens of ships and planes vanished mysteriously without a trace.

Bermuda Triangle, also known as the Devil’s Triangle, covers approximately 500,000 square miles of sea between Florida and Puerto Rico, stretching as far northeast as the island of Bermuda—hence the name.

There have literally been hundreds of sea vessels gone missing in this region of the Atlantic Ocean, as well as at least 75 aircraft to date, with no explanation.

In 1918, USS Cyclops, a World War I fuel tanker carrying 309 people, disappeared while sailing through the Bermuda Triangle.

In 1945, five U.S. TBM Avenger torpedo bomber planes from Flight 19 vanished in this terrifying region, while 13 men on a seaplane who went out looking for Flight 19 also never returned.

On May 15, 2017, pilot Nathan Ulrich, along with his girlfriend and two sons, vanished over the Bermuda Triangle.

USS Cyclops, carrying 309 people, disappeared sailing through the Bermuda Triangle in 1918


TBM Avenger bombers flying in formation


Till today, no bodies or wrecks from the 1918 and 1945 incidents have been found.

The spooky and unexplained disappearances that occurred in this region have baffled the world for nearly a century.

Now, a scientist has revealed that there might be a simple explanation to this much-debated issue.


"According to Lloyds of London and the US coast guard, the number of planes that go missing in the Bermuda Triangle is the same as anywhere in the world on a percentage basis,” said Australian scientist Dr. Karl Kruszelnicki
Being one of the busiest shipping routes in the world, Dr. Kruszelnicki claimed most of these strange incidents are likely to be the result of—human error.

“It is close to the equator, near a wealthy part of the world, America, therefore you have a lot of traffic.”

He contended that the Flight 19 incident could be due to a hangover suffered by the squadron commander, Lieutenant Charles Taylor.

The National Oceanic and Atmospheric Administration (NOAA) has also repudiated the myths and legends surrounding these strange phenomena behind The Bermuda Triangle. It stated on its website: “There is no evidence that mysterious disappearances occur with any greater frequency in the Bermuda Triangle than in any other large, well-traveled area of the ocean.”


Another theory explaining these strange disappearances was proposed by meteorologists who claimed that unusual hexagonal clouds creating air bombs of 170mph wind speed could be the mastermind behind the sinking of ships and planes. They stated that these air bombs generate blasts which could crash planes and plunge ships.
“The satellite imagery is really bizarre… These types of hexagonal shapes over the ocean are in essence air bombs. They are formed by what are called microbursts and they’re blasts of air that come down out of the bottom of a cloud and then hit the ocean and then create waves that can sometimes be massive in size as they start to interact with each other,” meteorologist Randy Cerveny told the Science Channel’s “What On Earth.”

One of the important factor play at there is dual gravity. Both dual gravity ac at there .
According to my conclusion. I have been telling the the whole world that there is more than hexagonal cloud, it is a actually variation of gravity. It is always there in the Bermuda triangle.

Dual gravity claim is by d.p( usmforu) have more research paper on it, That had never published.

I am coming with more new ideas because have less time ...

ARE WE LIVING IN A COMPUTER SIMULATION?



What is Simulation?

The term simulation is used in different ways by different people. As used here, simulation is defined as the process of creating a model (i.e., an abstract representation or facsimile) of an existing or proposed system (e.g., a project, a business, a mine, a watershed, a forest, the organs in your body) in order to identify and understand those factors which control the system and/or to predict (forecast) the future behavior of the system. Almost any system which can be quantitatively described using equations and/or rules can be simulated.


The Purpose of Simulation

The underlying purpose of simulation is to shed light on the underlying mechanisms that control the behavior of a system. More practically, simulation can be used to predict (forecast) the future behavior of a system, and determine what you can do to influence that future behavior. That is, simulation can be used to predict the way in which the system will evolve and respond to its surroundings, so that you can identify any necessary changes that will help make the system perform the way that you want it to.

Example

For example, a fisheries biologist could dynamically simulate the salmon population in a river in order to predict changes to the population, and quantitatively understand the impacts on the salmon of possible actions (e.g., fishing, loss of habitat) to ensure that they do not go extinct at some point in the future


Well, what if it is? What if this life is just a simulation of the real thing? What if you, in an incredibly meta act, are reading this on a computer while residing inside of a computer? Once inserted, the thought niggles away at us—we can’t think our way out of this quagmire. “What if you were unable to wake from that dream? How would you know the difference between the dream world and the real world?” asks Morpheus in The Matrix. Dude.
But now researchers say they've sussed out the whole situation for us. Theoretical physicists Zohar Ringel and Dmitry Korvizhini, who are based at Racah Institute of Physics Hebrew University in Israel and Oxford University in the United Kingdom, claim to prove the concreteness of our reality in a recent Scientific Advances study.
To understand what they found, it helps to first recognize what a computer is: it's essentially a machine that performs calculations. In order for a computer to simulate reality, then, the machine would need to have enough power to actually create the phenomena that we experience within its simulated environment. What the researchers discovered, however, is that storing the information required to simulate certain behaviors of even a couple hundred electrons would take more atoms than exist in the universe. For better or for worse, this world is real. Probably.

the quantum Hall effect. The regular Hall effect (normally just called the Hall effect) explains how, under the right circumstances, metals can display some interesting electrical behaviors. For example, if you take a a metal bar and send a current flowing through it, you expect electrons to keep moving straight ahead in the direction of the current. But when you apply a magnetic field perpendicularly to the current, the Hall effect predicts that the electrons will turn and start moving perpendicularly to both the current’s original direction and the magnetic field. The quantum Hall effect takes the standard Hall even further: when you take conductive material into an environment that’s both very cold (near Absolute Zero, or -459.67 F), and has a strong magnetic field, particles behave even more oddly. Kovrizhi and Ringel were trying to get a better grasp on why.


Two plus two is pretty easy to solve (the answer, in case you’re wondering, is four). These sorts of equations are fine for relatively simple systems—we can do them with a calculator, if not in our minds. But these kinds of easy calculations start to break down when dealing with the weird quantum behavior that occurs at the very very small (we’re talking about systems smaller than the goings on of individual atoms) level. There are more unknowns—and you can have an infinite number of particles interacting. That’s what is known as the many body problem.

“When you do physics and you don’t know how to solve something, you say, maybe I can just have my computer solve it for me and that will give me some intuition,” Ringel told Popular Science. So he and his colleague turned to quantum Monte Carlo, a family of computational methods that use random sampling to study complex quantum systems that can’t be solved directly. But the researchers discovered that for every particle they added to the system, the simulation became exponentially more complex. It essentially doubled in complexity with each new particle (not unlike the reproductive rate of a tribble), making the problem unresolvable.
It's not that people hadn't attempted to solve for quantum Hall before.
People have tried solving it using laptops, and big clusters of computers. Ringel and Kovirzhi didn't necessarily expect to succeed, but they hoped to figure out why it had never been done. It could be that humans aren't smart enough, or that physicists just haven't yet found the right mathematical mapping. The new study makes it clear that it's just not possible to simulate the effect. And to the study authors, that suggests it would be impossible for a computer to create our world.

Simulation Hypothesis

While many people take reality at face value, others believe the far more intriguing theory that we are living in a computer simulation. It’s a concept straight out of “The Matrix” (though its origin reaches much further back), and one of its supporters is Tesla and SpaceX CEO Elon Musk.


Musk elaborated on the idea during the interview:

The strongest argument for us being in a simulation, probably being in a simulation, is the following: 40 years ago, we had Pong, two rectangles and a dot…That is what games were. Now, 40 years later, we have photorealistic 3D simulations with millions of people playing simultaneously, and it’s getting better every year. And soon we’ll have virtual reality, augmented reality. If you assume any rate of improvement at all, the games will become indistinguishable from reality.

The contemporary version of the simulation hypothesis was introduced by Nicholas Bostrom, a British philosopher, in 2003. Simply put, the hypothesis states that there is a likelihood that advanced future civilizations would run equally advanced computer simulations of past civilizations. So, much like we play video games about ancient populations, they might do something similar, just much more technologically advanced. Some people even think that the events of the 2017 Oscars are proof of this theory.

Ringel and Kovrizhi showed that attempts to use quantum Monte Carlo to model systems exhibiting anomalies, such as the quantum Hall effect, will always become unworkable.

RECOMMENDED

Science cannot tell us if we’re living in The Matrix
PHYSICS
They discovered that the complexity of the simulation increased exponentially with the number of particles being simulated.

If the complexity grew linearly with the number of particles being simulated, then doubling the number of particles would mean doubling the computing power required. If, however, the complexity grows on an exponential scale – where the amount of computing power has to double every time a single particle is added – then the task quickly becomes impossible.

The researchers calculated that just storing information about a couple of hundred electrons would require a computer memory that would physically require more atoms than exist in the universe.

The researchers note that there are a number of other known quantum interactions for which predictive algorithms have not yet been found. They suggest that for some of these they may in fact never be found.

“Who knows what are the computing capabilities of whatever simulates us?”

If you, me and every person and thing in the cosmos were actually characters in some giant computer game, we would not necessarily know it. The idea that the universe is a simulation sounds more like the plot of “The Matrix,” but it is also a legitimate scientific hypothesis.


VIRTUAL MINDS

A popular argument for the simulation hypothesis came from University of Oxford philosopher Nick Bostrum in 2003, when he suggested that members of an advanced civilization with enormous computing power might decide to run simulations of their ancestors. They would probably have the ability to run many, many such simulations, to the point where the vast majority of minds would actually be artificial ones within such simulations, rather than the original ancestral minds. So simple statistics suggest it is much more likely that we are among the simulated minds.



LIFE, THE UNIVERSE AND EVERYTHING

If it turns out we really are living in a version of “The Matrix,” though—so what? “Maybe we’re in a simulation, maybe we’re not, but if we are, hey, it’s not so bad,” Chalmers said.
“My advice is to go out and do really interesting things,” Tegmark said, “so the simulators don’t shut you down.”
But some were more contemplative, saying the possibility raises some weighty spiritual questions. “If the simulation hypothesis is valid then we open the door to eternal life and resurrection and things that formally have been discussed in the realm of religion,” Gates suggested. “The reason is quite simple: If we’re programs in the computer, then as long as I have a computer that’s not damaged, I can always re-run the program.”
And if someone somewhere created our simulation, would that make this entity God? “We in this universe can create simulated worlds and there’s nothing remotely spooky about that,” Chalmers said. “Our creator isn’t especially spooky, it’s just some teenage hacker in the next universe up.” Turn the tables, and we are essentially gods over our own computer creations. “We don’t think of ourselves as deities when we program Mario, even though we have power over how high Mario jumps,” Tyson said. “There’s no reason to think they’re all-powerful just because they control everything we do.” And a simulated universe introduces another disturbing possibility. “What happens,” Tyson said, “if there’s a bug that crashes the entire program?”

So you can think that are we really living in a simulated world?....

So be in the next part about computer simulation.
