Time Travel

Time travel theorists ask, what if we could send scientific and medical information through time--perhaps a cure for AIDS?

0:47 If you built a time machine and saved your father you'd never build a time machine because you'd never have a reason to, so if you didn't build the time machine you didn't save your father so you did build a time machine... Grandfather Paradox.

Think about it, if there was a time machine ever built (to be able to go back in time), wouldn't there be somebody from the future now?

OR, maybe, we are the first future?

[lordsavior13]

we willn never send back a cure because if the cure existed the person who made the cure would have never made it so it would have been imposible to ever send it back in the first place'

[lordsavior13]

if you went back in time 2 save your father your father would have still been alive but hes nott so he cant go back in time

@nZGalaxy its proven time travel is possible thers something that i say to people and that is nothing is imposible

[BOB777777777700]

I use to time travel, but then I took an arrow to the knee.

I time travel every night....it was 10 pm last night...i closed my eyes and now i'm ten hours in the future..i might take a nap and push my quantum physics beyond my wildest dreams!! lol

@Bernadette61983 Well Number 1: This dude has a PhD, so i wouldn't doubt what he says. But secondly, from the double-split experiment with light you can conclude that light isn't just electromagnetic radiation, it's the photons in it that contain the radiation, plus we know it has a matter field and is also a wave so it's not just electromagnetic radiation.

[Bernadette61983]

At 2:26 he says, light could be used to control gravity but how did he figure that? Light is electromagnetic radiation which is influenced by gravity more or less depending on the amount of gravity, not the other way round. His statement doesn't make sense. At 3:07 if he can create a circulating beam of light, it should twist space. No it shouldn't. If he circulates his torch fast enough, he may create a slipstream but turning the torch on to get light won't affect the suction of the slipstream.

[TheBaldchipmunk]

What if we built a satelite that would take a picture of the universe and light up when that happens? Think about it, you would actually get the picture before you would see the beam of light flash, meaning we sent information faster than light (through time).
