Einstein claims that is impossible for any object (with a mass) to reach the speed of light, however I have many questions that I would appreciate if were answered.
To start with, the Largest Hadron Collider can accelerate an electron to a speed equivalent to 99.9999991% of the speed of light and the weight of that electron would be equal to the weight of a train moving at 80 km/h, which is huge (considering the initial weight of the electron), yet not infinitely huge. And it was only a tiny city on the border between Switzerland and France that was able to do it.
Moreover, I once read that it would physically impossible for a spaceship moving at the speed of light to reach the end of the universe, because universe is expanding at the speed higher than the speed of light. The only way something could move at the speed of light is if it had an infinite amount of energy, but then that doesn't make sense. For the universe to have an infinite amount of energy, the space it must be contained in must be infinite also, but since the universe is expanding, it can't be infinitely large, because otherwise it wouldn't have a value to its size.
I also read somewhere else that in first second (up to 1^-37 seconds) after big-bang the laws of physics were different, in fact the 4 forces (electromagnetic, gravitational, weak and strong) didn't exist but there was only one force (Unified Force, where gravitational force was as strong as other forces) which later split into two different forces which after split again to become the 4 that we know now. So I thought that maybe in those first second, there was no limit to the speed, and it was that initial push that set us off on the speed faster than the speed of light, and then following the Newton's law of motion, the universe kept increasing at that speed because there were no external forces (assuming that there is nothing outside the universe) that would slow it down.
And also wouldn't the particles during the "inflation" expand at a faster-than-the-speed-of-light velocity?
Any opinion or answer will be appreciated,
Thanks
