i dont know how interested people are in this stuff....i am really interested in it, so i am going post another video...again featuring dr. michio kaku (the dude who can ice skate)....this one talks about time travel....probably the most interesting part to me is the person who is building a life size replica of h.g. wells' "time machine"....and how he postulates how it would work....which is pretty interesting....he says he uses magnets to move it faster and faster back and forth about one proton's length...until he is moving at the speed of light...but seeming to be stationary....at which point general relativity would kick in and time would slow for him, and he could reach the future...of course he makes no mention of how he would "return travel" because relativity doesnt allow this....but i like turning science into fiction....and after hearing how carl sagan was motivated towards cosmology by science fiction i think its cant really be a bad thing to have this sort of stuff out there....either way this is a god introduction to the science of time....there are a shitload of these videos online.

Anyone can postulate anything though. I can like postulate that I am going to drink a whole lot of beer and then not say something stupid.
Anyway, time travel is totally boring.
did you just dis me?
my point was that you can postulate anything, but the interesting part is HOW people postulate it. this guy came up with his wacky idea of time travel based on a book of fiction mostly, and the laws of physics a little bit.
Soooooooorry - I guess that did sound like a dis. What I meant, obviously!, is that time travel is what we are always doing. The thing about knowing the future or being able to change the past is that I think it would make life totally boring. Like a spoiler in a film review or game genie. The most exciting thing is either A. not moving at all in time or B. Moving sideways to different times. Maybe there's one where I'm not a jerk.
Anyway, I kind of was dissing that postulating fool 'cause of it takes an infinite amount of energy to accelerate something to the speed of light.
But, like I was saying the other day, I like the idea of scifi being a generative force for science. I was reading this book on linguistic category theory and it credits most of the generation of the ideas to Wittgenstein, who mostly just sat around in front of a room full of students, complaining about how he didn't know anything about anything, or writing imaginary conversations. It's not like he was looking at brain scans or studying grammar in small scale societies.
So, despite the crap we were talking about how big science is developed further by big machines (i.e. CERN particle accelerator), I think there are alternative paths to knowledge.
Pizza paths.
Anyway, when I dis you it will be very clear and to the point.
SMEE!
