Hi everyone. I'm new to this forum...I just wanna make it clear that I'm an engineering student, thus I don't wanna look conceited with what I'm going to say. Some day ago, I was watching a documentary talking about the universe ( its expansion in particular), in which it was shown that ( how we all know), the universe is not just slowing down, but rather speeding up, at a tremendous rate. Scientists now have tried to explain it by introducing dark matter into their equations, unfortunately with not so many results. So my question is ( I don't have the knowledge to propose a new theory, I just don't understand the existing ones): If we, in classical mechanics, accelerate a little particle, from a velocity say, v to v2, the acceleration will go up from 0 to its final value, then in an infinitesimal amount of time dt, the acceleration itself is growing. In the second place, if we consider the special theory of relativity, it just states that : if a particle travels at a speed near the speed of light, time dilatates itself, and space compresses itself. That leads one to think that time and space are something like two complementary values, two things that have a constant sum (if one increases, the other one decreases and vice versa,). The point is : wouldn't be possible that the universe, since the start of the big bang, started from an initial value 0 of the acceleration, and then considering the time it passed since the birth of the universe, like an infinitesimal amount of time dt, the acceleration is still going to reach its final rate?. The speed with which the universe is growing could then be explained by the fact that time is, in a certain sense, compressing itself, than causing this tremendous acceleration. Thank you everyone for your answers. I'll accept any analysis over this subject (please consider that I'm just an engineering student, I'm no scientist ).
