The Big Bang Theory is a theory attempting to clarify what occurred toward the start of the universe and the early advancement of the universe. Researchers and physicists have discovered that our universe had a start. Be that as it may, before the universe was made, there was nothing, not in any case space or time existed. Be that as it may, after, our universe was made. The Big Bang theory clarifies what occurred during and after the universe was made. Although there were numerous theories attempting to clarify how the universe developed, the Big Bang theory was the most famous.
The Big Bang begins by saying there was nothing and after that there was something, this is on the grounds that it is extremely obscure what existed previously. Forms of the theory propose that the mass known as the universe originated from space. A few specialists differ that the mass originated from space since they trust that space did not exist before The Big Bang. They trust that space appeared as the universe did.
Every one of these theories and the diverse clarifications for them should stay unanswered because we presently cannot seem to think of the way to explain the mystery. Similar to the few theories of what existed before our universe, there are distinctive theories on what caused the theory of how things came to be. A few specialists trust that there was a blast that made the mass be tossed out into space like the name of the theory, a huge explosion.

There are renditions of this thought that theorize the impact happened from some sort of old obscure form of energy. Others on the hand, trust that since nothing existed before the enormous detonation there could not in any way, shape, or form have been a blast and that the mass just showed up. This also is another unanswered inquiry in the theory of the enormous blast that will stay unanswered on the grounds that we cannot demonstrate or refute any of it.
The theory that space did not exist before the big bang theory was further elaborated during the sixties and seventies. The notion was based on Einstein’s Theory of Relativity about time, and was proposed by British scientists Steven Hawking, George Ellis, and Roger Penrose. The three of them added onto the original theory to include the belief that space and time did have a finite beginning. They calculated that space, time, matter, and all energy began inside the singularity, but still did not offer and answer as to what it was that the singularity appeared in.
The beginning of the universe according to the Big Bang Theory, started off as a very small, very hot mass. This mass has been said to have been only a few millimeters long and 10 billion degrees but didn’t last this way for very long. The size and temperature are believed to have only remained this way for a few seconds before it started evolving. The whole theory bases its ideas off of the belief that the universe started off as small as a pebble and eventually grew to be the size of the universe that we know it as now.
The temperature change between the first remnants of the universe and the universe as it is now is a fairly large change. It would be easy to question whether this theory is true or not, had it not been for the evidence that was found in the late sixties. The notion was first thought of in 1948 by Ralph Adler and a team of other scientists. They believed that if the universe was as hot as we thought it was, there should be some kind of evidence of the afterglow that resulted from the grouping of electrons and nuclei.
This combination formed neutral atoms, which allowed light to be seen and is now known as cosmic microwave background. CMB as it is also called, was accidentally discovered when two radio astronomers picked up higher than normal temperatures of 2.725 degrees Kelvin from a radio receiver they were building. Arno Penzias and Robert Wilson’s discovery found this cosmic microwave background permeated throughout the galaxy, proving that such high temperatures did exist.
An explanation on the small size of the universe in the beginning is that it is a singularity, which is described by physics as a zone. These types of zones contain gravitational pressure that is immensely powerful. This powerful type of pressure contained finite matter that was compacted into infinite density. The way it is explained makes it seem as if all the possibilities of the universe were housed inside of an object small enough to fit inside one’s hand, which is pretty hard to believe.
After this small mass known as the universe came to exist, it used the power of the gravitational pressure to expand. This was some expansion because it took the small mass from the size it was to the size we now know the universe to be. One suggestion about the rapid increase in size is that over time the mass cooled and began to expand. It is believed that the universe continued to go through expansion and slowed down over time.
The universe is still expanding now, just at a very slow rate. The phenomenon of expansion was first discovered by Edwin Hubble, and appropriately named Hubble’s Law. Hubble’s Law does not just stop at the theory of our expanding universe, it also covers the expansion of other galaxies. It has been proposed that other galaxies around us are moving further and further away from us.
The farther away the galaxies get the faster they are moving. It is possible that the moving galaxies can reach the speed of light, and will be too far away from us to see from our galaxy. If they reach such speeds then there will be no way to bridge the gap that will be created because as Albert Einstein’s theory of relativity explains, there is nothing in the universe that can travel faster than the speed of light.
Expansion is a huge aspect of the Big Bang Theory, without it there would be no theory and proposedly no universe either. Some scientific experts take the expansion theory yet another step further. They believe that galaxies go through a series of expansion and compression rather than a onetime occurrence of expansion. It is proposed that we are in the middle of an expansion phase right now. If this is true then there will be a time when the universe compresses back to its original state. There has yet to be proof of this theory because we haven’t experienced any signs of our galaxy compressing.
The expansion mentioned in the Big Bang Theory can also suggest that there are other universes in existence. Physicists believe that when the small mass known as the beginning of the universe began to expand, it could have done so in such a rapid way with such force that it let off different sections. These sections are thought to have potentially grown at different rates, causing a difference in time and space. These differences could result in other universes with completely different traits than ours. Although more research needs to be done, physicists feel very strongly on their theory of a multiverse.
The rapid expansion is also responsible for the matter found within it. During the great expansion of the universe, some matter decayed and others combined to form atoms. The atoms that were formed eventually made the stars and the planets contained in our universe. A Belgian priest named Georges Lemaitre actually proposed that our universe started off as a primordial atom. Seeing as the universe we know now is made up of a large number of atoms, it is only right to look back at their first existence in relation to the Big Bang Theory.
Some experts believe that protons, electrons, and neutrons were in existence since the beginning of the universe. Helium and hydrogen atoms are said to have been created because of the big bang, with hydrogen being one of the most important atoms.
The whole theory and all the little ones that came about because of the first Big Bang Theory still does not address every one inquiries of the universe, or what may be past it. They do offer loads of clarifications and conceivable answers yet such a large number of things are still left open to question. I would find the entire thing difficult to accept in the event that it were not for a portion of the logical disclosures like the infinite microwave foundation.
Indeed, even with these logical revelations despite everything I cannot be as sure as certain individuals are that the enormous detonation is the reason for the universe, or that any piece of the theory is even right. It might simply be that the clarification and the theory all in all is simply outside my ability to understand, however I feel like without recognizing what was in presence before The Big Bang it is hard for us to know reality about what truly occurred.
