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?

  • 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'

  • 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

  • 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

  • will never stop. It doesnt make sense. You also cant go back in time because you didnt exist then. If you didnt exist, you could never make yourself exist, its not natural.

  • time travel is impossible...it would put you into the middle of space, which doesnt exist because space is infinite...and time isnt matter, it is a number of a measurement. You would also have to spin the light at the speed of sound to distort gravity and space...and also...space isnt anything...it shows you where there is nothing, you cant move nothing...nothing isnt something...it just has a name to define it...and because space is infinite, you will keep going back in time forever and you

  • @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.
