and in quantum physics (string theory to be more precise) the universe has 11 dimensions
But string theory is all technically just mathematical conjecture with no scientific support, because all the things theorized in it cannot be tested by experiment. Basically string theory is just Mathematicians' way of perpetuating their status quo, their way of keeping students busy, and their way of seeming like they're still useful to society. And the fact that it catches on like a religion in which the people who most believe [ i.e. the students and teachers] are the people most deceived-- THAT, my friends, is phenomenal.
Light is incredible.. it's weird how "light" sets the limit for velocity in the universe, and not gravity or sound..
Well, my physics teacher, although she was a total flake, said that scientists broke the speed of light by accelerating photons in some environment which was conveniently unable to be reproduced, and for a moment I believed her. I
wanted to believe her. But now I think she might have been lying.
And there's no logical reason for sound to set the universal speed limit, since sound is just vibration.
However, the speed of gravity is a perplexing idea. Since matter has never been created, the speed of gravity is unknown, and it may very well be infinite, instantly taking effect when matter is introduced into space [like the speed of darkness]. But if we could convert energy into matter as E=mc^2 declares possible...we might be able to discover the speed of gravity.
