So he's not so much talking about time travel as he is creating a communications device much like the ansible in the Ender's Game series?

What would stop those other universes from time traveling to our past and changing things? It still doesn't work.

what if this is the messed up timeline, and in the other one we are all super intelligent beings who know everything.

I don't see why that's not possible?

I am not as smart or anywhere near as intelligent as them scientists, but even i know that time travel will never ever be possible.
The apparent notion conflicts heavily with the law of nature, and everybody knows that the law of nature overrules all.

Apparent 'known' laws of nature. Relativity once conflicted with known laws of nature, now it is one.

1. A message being received before it's completed is already possible. We do it everyday, be it in normal human to human communication, where we already know what the other person is going to say, or when we are typing an sms and the phone already knows what word we want even before it's fully typed. With further advancements in processing power and AI routines, the phone can even sense context, relate our message to the previous one, tie it together with our way of writing and thinking and basically have a high accuracy in predicting the whole message. Not exactly 100% correct all the time, but it would enable a message to be sent even before it's written.
2. Time travel is impossible in a universe. If time travel was possible, then somebody in the future would have already broken security protocols, traveled back in time and messed things up. It's just too tempting not to do it. The only possibility is time travel in paralel universes, where we can travel back to a "photocopy" of our past and change things, but they won't reflect themselves in our universe.

1. A message being received before it is completed works on the basis of assumption and has a large margin of error which in turn puts this theory in absolute invalidity of the topic at hand.

2. I agree that time travel is impossible, on a more fun note, how do you know somebody in the future hasn't already "broken security protocols and messed things up"? tongue.gif

To discover the earths shape didn't require for anything to be altered, except our awareness.

But really, people used to think that it was impossible for us to fly, that the earth was flat and that the sun orbited the earth, that there were only 4 elements in the world, and so on. If everyone already knew what was or wasn't possible, than we would have no more discoveries to make. I'm pretty sure everything isn't already completely figured out.
