No parrallell universes space was proven to be flat.
From our current understanding, the universe is flat. There is much we don't know.

How do we know that WW2 never originally happened, but then some tit (from the future) created a time machine, went back, told Germany to invade Europe, which then led to WW2?

We would have to connect to a alien time machine built centuries ago to be able to go back to when their machine was built, assuming any Aliens even built time machines.

By god!! Hitler is a time-traveling Nazi Muslim just like Obama!! How does Colbert get all this information so much earlier than everyone else??

Because time moves in one direction, farward, with the big bang.
Do you understand this ?
When the big bang happened ,and time and space as we understand it ,were created, meaning we can measure them, time, and space, we have found that time is linked to speed ,c , the speed of light, through dilation, and theory says that we MIGHT, be able to travel to the future, but never the past, and only through time dilation can we maybe do that, and its a big big maybe !
Short of that , for us to be able to travel into the past, would mean theres multiple universes all occupying the same space ,but time does not end,it goes on, farward, so for there to be multi-verses time must loop, end, it doesnt it moves farward always, meaning for every millisecond a new universe must be created, its not possible.
To go back in time means all the multi-verses are there right now, just at a different time or point in time relitive to our time, it means time must have an ending, it cannot end, time cannot stop , it is a constant we have used scientificly for ever.
Not to meantion where the energy is comming from to create new ones every millisecond !
Also every universe would have to evolve precisly the same as ours, LOL @ that, if that were even remotely possible l recon we would have detected life in our own gallaxy by now ! hahaha
With or without time travel !
Next you'll be saying that us humans , LOL, in the future, went back to the past, LOL, to the beggining of the Earths creation and seeded life, LOL, and thats why were really here ! LOOL !
Or maybe you will be wiping yo butt on the brasco one day, and some twat from the future, lol, probly one of ya cousins hahaha, will stuff up the time machine and we all end up stuck in a 3 second loop in time forever hahaha, forever being 3 seconds, then your born again ! hahaha to wipe ya butt over and over and over and over and over dont ya recon the laws of physic's would breakdown at some point ? hahaha
pretty funny stuff, yall nutz !
Looped quantum theory is interesting but probably wrong ! And its probably the best hypothesis out there for multi-universes.....

I'm a big fan of shows like Doctor Who and such, and the time travels in things similiar to it always gets me thinking - can we actually find a way to travel in time, and if so, can we change events?
I love Dr. Who myself, and if we did have the ability to time travel, I'd go back and stop Obama's election.
Hmmm...think of it this way. You could not listen to or send radio signals until you built a radio. The signals are there to listen to but you cant make make use of that til the technology was invented to do so. Same with a transmitter.
Just for the argument lets say time can go forwards or backwards and movement betwen stars was instant. Ir doesnt but pretend for the moment it does.
If you could send a radio signal back in time no one could receive it until the radio was built.
Ergo, at such and such a date you build a time machine. Lets say fifty years from now someone from the future wants to go back in time, like the radio signal analogy, you could only go back as far as a time machine existed. If it didnt exist how would you receive the signal?
Further, what if some Alien race built a time machine based on similar technology to ours a billion years ago. They could travel forward in time and step out of our machine or a time machine built in the future.
Similarly we could travel back to when the Aliens built their first time machine but no further back than that because a machine would not exist to travel back to.
Degrasse Tyson seems to be assuming that we would never be able to build a machine that would move the machine and humans from point A to point B in space and time but that we could build a point to point system similar to a transporter or teleporter that could send a signal back in time but that we would still need a machine to receive said signal.
Im guessing because you can accelerate energy to the speed of light but so far our understanding of physics at current says we cant accelerate matter that fast.
I saw all this on a interview and I find the man fascinating to listen to.
I have a large amount of respect for Neil Grasse Tyson and Michio Kaku.

What signal does the time machine have to receive?

Pardon my thinking so, but I reckon that seems pretty daft. That means that you couldn't travel back to before you were born because you would not exist to travel back to. Same goes for your clothes, the air you breathed, the lunch you ate, the glasses you wear, the stuff you carry, etc ad infinitum.

How fast you accelerate anything depends only on the amount of power you put into it. And you can't accelerate energy. At least, not as energy, anyway.

This I understand.

If you had a Time Machine, wouldn't that time machine travel with you, to the past destination of your choosing? If not, then why not?

Based of an assumption.
If we were to go with this assumption, then it would explain the above comment, if however, this assumption is wrong, then my above point still stands.
Your close einstein proved trime travel was impossible but time viewing was in theory possible.
Huh?? Time viewing??

The radio signal would be there regardless of if there was a receiver. Perhaps the same could be true for time-travel.

Interesting thought to consider.
If there was such a species I think it would be either 100% or almost 0% chance that the different time-machines would be compatible. Can't say for sure which until we know more about time-travel.

What if the signal works like a radio signal, in that it can be received by multiple machines?? The signal could also degrade as it got farther from the source.

The signal from the first time-machine, containing instructions on how to reintegrate the transported matter.

You don't understand. It has nothing to do with the matter transported through time. Just the time-machine in itself. The way I see this theory is that one machine disintegrates a person, but records their molecular make up. It then sends a signal through time to another machine that reconstructs you based on the 'model' (for lack of a more appropriate word) contained in the signal.

It could. But that's not how this particular theory works.

People seem to think theories expressed here actually represent something that we actually know. All theories on time-travel are just opinion until a time-machine is actually built. We aren't trying to prove our theories as we have nothing concrete to base them on at this point. We are merely suggesting possibilities. So either Neil Degrasse Tyson's theory & Dr. Who's theory remain valid until proven wrong.
