Origin of the Universe tenor.com |
This Shruti, about five thousand years old, is still as relevant today as it was when writing it. The origin of creation is still a mystery. What was before creation? Who composed it, when and why? What happened that created this world? There are many unresolved questions that no one has a definite answer to. There are some theories that answer some questions and raise some new questions. The theory to answer all the questions has not yet been revealed. The most recognized theory is The Bing Bang Theory.
The Big Bang Theory
In 1929, Edwin Habbal made a surprising discovery, he found that in space you can see the sky in any direction and other celestial bodies are rapidly moving away from each other. In other words, the universe is expanding. This means that all the substances of the universe in history must have been closer to each other than today. And there must have been a time when all celestial bodies would have stayed in one place, but would you believe it?Since then, astronomers have tried to analyze the circumstances of how cosmic matter is becoming far away from the state of being very close to each other. At some point in history, perhaps 10 to 15 billion years ago, all the particles of the universe were very close to each other. They were so close that they were all in one place, at the same point. The whole universe was in the shape of a point. This point was of infinite density, infinitesimally small. This point form of the universe must have been extremely hot due to its excessive density. In this situation, no laws of physics, mathematics or science work. This is the situation when a man is unable to estimate or analyze in any way. Time or time also stops in this situation, in other words, time and time do not matter. * In this situation, for some unknown reason, the universe suddenly started expanding. The universe was born with a great explosion, and matter in the universe started moving away from each other.
1. 10–43 seconds after the Great Eruption, only very high energy (in the form of photon particles) existed. At the same time, fundamental particles such as quarks, electrons, anti-electrons (positrons) were formed. We will learn about these particles in the next digits.
2. After 10–34 seconds, particles such as quarks and antiquarks formed in large quantities due to the collision between the excess energy of the fundamental particles. At this time both the particles and their counter-particles (1) were being formed, some of which were ending by colliding with one particle and their counter-particles (2). At this time the shape of the universe was shaped like an orange.
3. After 10–10 seconds, the antiquarks collided with the quarks and were completely obliterated, creating the photon from this collision. At the same time, protons and neutrons were also produced.
4. After 1 second, when the temperature was 10 billion degrees Celsius, the universe began to take shape. At that time, the universe consisted mostly of photons, electrons, neutrinos (3) and some number of protons and neutrons along with their particles.
5. Protons and neutrons began to form nuclei of elements together with what we know today as hydrogen, helium, lithium, and deuterium.
6. When three minutes had passed since the Great Explosion, the temperature had dropped to 1 billion degrees Celsius, the element and cosmic radiation had formed. This radiation is still present and can be felt.
7. After 300,000 years on the move, the expanding universe still did not match the present-day universe. Element and radiation had begun to separate from each other. At the same time, electrons were forming atoms together with the nucleus. Atoms were forming molecules.
8. After 1 billion years of this, a certain shape of the universe began to form. Around this time the quasar, the protogalaxy (an early form of the galaxy), began to be born of stars. The stars were producing heavy elements by burning hydrogen.
9. Look at the situation today about 14 billion years after the great explosion! Their solar system has been formed with stars. Atoms have formed hard molecules. In which some hard molecules are fundamental particles of life (ex: Amino Acid). Not only this, many stars have become black holes.
The universe is still expanding, and the pace of expansion is increasing. You can compare the expanding universe with a balloon, just as the points on the surface of the balloon are inflated away from each other, in the same way, the sky is moving away from each other. This expansion is happening in such a way that there is no center, every galaxy is moving away from the other galaxy.
The Alternative Theory
According to this theory, time and space did not start simultaneously with the great explosion. It is believed that time is eternal, it has neither beginning nor end. Come to know this theory. The galaxy and a group of celestial bodies move away from each other in space. According to the theory of the great explosion, the speed of the celestial bodies moving away from each other is less than that of the time after the great explosion and today. Taking this further, this theory says that in future the gravity of celestial bodies will be able to stop the speed of this expansion. At the same time, the opposite process will begin i.e. the contraction.All celestial bodies will come closer and closer to each other and eventually become narrow as a single point. At this moment another great explosion will occur and a new universe will be formed, the process of expansion will start once more. This process has been going on since time immemorial, our world is one of many in this process of expansion and contraction. Even before this, many worlds have been created and will continue to be built in the future. The process of shrinking the universe to a point is known as the Big Crunch. Our world will also be destroyed in one such great contraction, which will give birth to a new universe by a great explosion. If this theory is correct then this contraction process will start after 1 trillion 50 billion years from today.
The Quite State Theory
The theory of the great explosion is the most accepted theory, but not all scientists agree. They believe that the universe is eternal, it has neither beginning nor end. According to him, the universe did not start with a great explosion or it would end with a great contraction. This theory assumes that it was and will always be the way the universe is today. But the truth is the opposite. In this issue we discussed the origin of the universe, in the next issue, we will discuss in detail the basic principles in the great explosion and physics.1. Particle and anti-particle: Every fundamental particle of matter is also antagonized. Such as anti-electron (positron), proton-antiproton, neutron-antineutron, etc. for electrons. When a particle and its antagonism collide, they both turn into energy (photons). If you ever get your anti-human then don't make the mistake of joining hands with him. Both of you will turn into energy in the form of a bang.
2. It is also a mystery that at the time of the creation of the universe both particles and antimatter formed, but why is the amount of particles so high? Does Anti Universe also exist?
3. Neutrinos do not mean neutrons, they have the same mass as electrons but do not have a charge (+/-).
