The beginning of time is a common phrase, used to describe something that has been going on for an almost endless amount of time, but did time really have a beginning, and if so, when? When Einstein was formulating his theory of relativity, he thought as most other scientists did, that the universe was eternal, and that time had no beginning. He was puzzled by the news after his publication, that the universe was expanding.
Einstein’s equation E=MC2 means that to find out the number of kilojoules of energy in a kilo of mass, you times the number of kilos of mass by the speed of light squared in kilometers per second, and you get an awful lot of kilojoules per kilo. The same equation works in reverse, Mass equals energy divided by the speed of light squared.
Einstein thought that these two equations proved that the universe was eternal,without beginning or end, but I believe he became too scared to keep saying that, because, he would have gotten a lot of hate mail from Christians, who believed that God created the universe, at a set point in time. Also when it was discovered that the universe was expanding, the majority of scientists at that time, who were in most cases Christian, took it as proof that the universe began just like it said in the bible, and it is very hard to go against a majority view in science, without being discredited.
There are two basic theories these days, the big crunch theory, and the big freeze theory. In the former, the universe is expanding faster only due to propulsion from the nuclear reaction of the stars, and they travel faster away from the gravity of each other due to this propulsion, but when the stars burn out, and cool down, they will turn into black holes, (a black hole is very cold matter that is so cold the electron stops revolving around the nucleus, taking away most of the volume but not the mass), and the gravity of these black holes, given no outward propulsion, will suck each other back into the center creating another big bang. This process has and always will continue, for eternity, meaning there could be no beginning, and no end of time.
The big freeze theory suggests that there was a beginning of time, and that the universe came out of nothing, or perhaps a singularity, in which time did not exist, and that it will continue to expand forever, decaying into massless particles. (Hawking raditation due to proton decay, is unproven, as it will take billions of years before it supposedly happens). The problem with the big freeze theory, is that the laws of physics do not allow something to spontaneously come out of nothing.
In a universe with no mass, no energy, and no time, there is no reaction that could have taken place to create the universe. Time is relative, and it could be said that time may slow down, almost to a complete stop inbetween one universe and another, but there was no beginning of time or space, it simply isn’t possible. The universe has to be eternal, moving in circles from one reincarnation to the next. The idea that something can be created out of nothing is not a scientific argument, it is a religious one.
