MULTIVERSE

You never died because you are made of atoms.. your existence always remain in the universe...
By d.p


We are going to understand the highly specified controversial Theory, if we go beyond the earth milky way and other distinct galaxies, we may find that our universe is not the only universe but instead part of the vast complex of the universes that we called MULTIVERSES
Now the idea of multiverse is strange one mean most of raise to believe that universe means everything . But it is strange to believe that multiverse is exist and these multiverse have different fundamental properties different dimensions.

At 1929 great astronomer ediwin hubble realized that distinct galaxies are rushing away from each other, it's expanding. This was the revolutionary idea but know that universe was static and expansion must be slowing down, that is much as the gravitational pull of the earth slows the an coin tossed upward the gravitational pull of each galaxy on other must be slowing the expansion must be slowing down. 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 .. so in the future 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.

in the future there might be many things about the space will come to us .

"THE STRING THEORY"

Vibration produces everything

It is exist due to the physicists.
Brain Greene



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 he like 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 .
Let's go to 2nd question does this theory work when you applied in the world around us. Einstein and many scientist work on try to find this frame work applied to physics​ of the universe. But they won't find the unified theory that explains everything. So here comes the string theory which can explain everything might clear our doubt.the theory which try to understand the basic fundamental individual uncuttable Constituents making up everything in this world around us.

If go inside the Apple you will find molecules then atoms then subatomic particles. Electrons orbiting around the nucleus, with nuetrons and protons even they have smaller particles inside of them known as quarks conventional idea stop there . Here the new idea of string theory

if go inside you will find a vibrating strings and these produces different patterns they don't produce different musical notes rather they produce different particles making up the world around us, vibrating in different frequencies produce the different particles, and different particles are responsible for everything around us, so you will find different particles . gravitons , quarks, electrons are all built up by one place. So if you see the vibrating string it's vibrating but Changes it's dimensions it is difficult to calculate the dimensions so string theory defines that yes extra dimensions exist .

Vibration determines everything.

One of the goals of Physics is to find a single theory that unites all of the four forces of nature. These are; electromagnetism, gravity, and the strong and weak nuclear forces. The first two are familiar. Electromagnetism is the force that holds a fridge magnet to a refrigerator while gravity is trying to pull it off towards the earth.
The strong nuclear force is responsible for holding the central part of atoms (their nuclei) together, while the weak nuclear force is involved in the decay of these nuclei.
In the attempt to tie all the four forces together a lot of interesting ideas and new theories have been proposed. One of the most promising of these new theories is string theory. In attempting to unite gravity with the three other forces, string theory requires us to change the way we view the universe.
According to the theory all particles are actually tiny vibrating strings and each type of vibration corresponds to a different particle. The different particles are like the different notes that can be played by bowing a violin string. However, the strings of string theory almost certainly would not look like violin strings.
String theory also requires us to accept the existence of extra dimensions in the universe. We are familiar with the four usual dimensions: up-down, forwards-backwards, left-right and time, but string theory requires seven more dimensions!

A universe of eleven dimensions seems strange to us but many physicists think these extra dimensions are possible and are looking for ways to detect them.
The attempt to unify the 4 forces of nature is one of the most exciting areas of physics and I hope to be around if this is successful, whether it is string theory or some other candidate that is successful. On the other hand there is the possibility that no single, theory exists that can describe all the forces of nature in a neat and tidy way as we would like.
Whatever the outcome, scientists from all over the world will continue working together to discover what could be the ultimate theory of everything.
String theory can make us understand everything and next part about multiverse.
