This might be a stupid question, but it came to me the other day while reading. Since the speed of light is the same in all frames what would happen if you were chasing a light beam at .999% c, so you were heading right for it (but could never catch it) and it is ahead of you traveling at c. If...
If these strings make up everything, why do they keep talking about it making up atoms, the thing that makes up only 5% of the universe, what about dark energy and dark matter?
I am asking, if you think that it is theoretically possible to travel through time, and if so, how you think this goes along with parallel universe theory?
How did they come up with all of this? Is it just a another mathematical convenience? Is there any evidence for any of this? I understand that math is the universal language of science, but just because the language is perfect doesn't make the statement true. F-theory goes as far as including to...
But what about the little accepted F-theory, and is validity? It has math to back it up too, being that math is all that backs up M-theory, why couldn't F-theory be the next TOE?
Ok...I know there have been tons of threads on this, but I would like to hear some opinions on this. So, after reading and reading about this I have learned that there are tons of theories and reasoning as to why it is possible, but what I really want to know is what all of your opinions are...
Since Andromeda is accelerating toward us and since gravity is the only force that acts at a distance, as well as dialates time, then is it possible that the closer Andromeda gets to us, the slower time goes? This may be very farfetched, but I by no means am not a physicist, and this is just a...
I know that electromagentic waves do not need any type of medium, but why wouldn't it be possible for dak matter to act as a medium for waves such as light?
