Hey guys, my mind has been racking for the past week or so, and I'm just wanting to make sure I have all the right info. At first, I was like, "How long would it take to get to Gleise 581 g if I accelerated at 1 g for a year and coasted". That was pretty cool to think of and get the math and stuff on (I'm no math major, in fact I understand very very little math), but I love the theories and concepts and laws that go with them. So then I heard about the Alcubierre Warp Drive...then I heard that it's impossible. Whatever, but I noticed how they talk about all this power that's needed to do this thing, and it's incredible! So I started looking in at that, and I keep going back to the same thing...we need energy, and lots of it. Energy is E=MC2, I know that. I know that certain particles give off certain amounts of energy (hence the atom bomb), but...what about light? I mean, light goes the "speed of light", right? I also know that photons don't necesarily have a "mass", which is why they can move around at the speeds of light unlike other forms of matter. But my question is this....shouldn't it be possible to use the energy FROM light? I'm just thinking, E=MC2, which means that you should be able to move that formula around a little bit, and find out how much mass and energy something moving at the speed of light would have. It just doesn't make sense to me...how can someething be moving at the speed of light, yet have no mass, and wellll....darnit ENERGY! Why does light not have an abundance of energy? And if it did, why couldn't we utilize it? Why can we flip a switch and a filiment causes electricity to flow and electromagnetism and the whole shibang, and you have LIGHT out of freaking nowhere, yet...no energy? I'm sorry, I'm just having a hard time wrapping my head around this, because, well...here's my understanding and train of thought: If light can go the speed of light, so can we. I mean, why not? Right? Except now I've learned this: Light has no mass, we do, hence we can't go the speed of light. So then the most realistic though is that the only way to go the speed of light is to reduce your mass to zero...which pretty much means not existing, but then that would mean light doesn't exist since it has no mass, and...holy freaking donkeys and cows this crap is confusing. Can someone explain this to me because it's really not making sense... Thanks!
