So I just started thinking about this and actually thought it would be an excellent feature in a book. So ASSUMING we could time travel, here's some things people never seem to consider:
-Scale of the universe at present vs. scale back then. There's no way for us to know if the universe is not 50x larger or smaller in an alternate time because we exist at the same scale...so if we time traveled to a time the scale was different...
-Speed of the Universe. What if time was flowing much faster in the universe at a different time that we traveled to? Would it be like inertia, like we would slowly start speeding up to the speed of the time medium we entered? Or would we be a different speed of time the whole time?

I'll think up some other factors, but I love saying stuff like this to people cuz they just say, "ow" and then try to think about it again and fail. It's kind of like Inception in the sense that it was an idea no one had really deeply considered.

So...discuss if you think this would be cool in a book or something, and any other things to do with time.

wow that would be cool in a book or something

Theoretically a time machine MUST be able to turn itself and its drivers invisible and intangible, then cryogenically freeze itself and its drivers to travel forward. But to travel backward all you need to do is move faster than light, which we have ALMOST achieved.

Sorry, but you just seem to be not thinking these things through. I don't know about the first one (something in my memory's bothering me about it, though- now THAT would be good in a book!), but the second one's just plain off. If time passed more quickly in another multiverse, then we would feel the effects immediately. Either (a) time would travel slower for us, or (b) we would instantly snap to the new speed of time. I'm going with b.

Oh, and Pikachu- up there just a post above, a time machine wouldn't turn you invisible. It would just make it so you don't see time passing as much. To rephrase, one second for you would be the equivalent of like centuries for a non-time traveling person. And why cryogenically? And you couldn't have found a word that I didn't need to look up?

If we ran into our former selves, would we still have the memory of running into an older version of ourself?

To the universe going at different speed one: Time is personal. The faster you go the slower time goes, and the stronger the gravitational pull is, the slower time goes. So time is different everywhere. Ex: If you fall into the black hole, time would stop because the gravity

*I always thought going back in time was impossible because you couldn't go faster than the speed of light, but those neutrinos a little faster might change that.

Woah.

Never thought of that.

Yes.

You know, there's a possibility that neutrinos are massless. That makes their going faster than c perfectly compliant with the laws Einstein thought up.

Apparently time travel is one-way

I agree. You'd have no way of getting back. And so you would also alter both that time(the food you ate, plants you stepped on, etc.) and your normal time because things would be different without your presence.

OW ow ow-ow-ow-ow-ow-ow-ow-ow

Can I get sone tylenol...?

JK, sounds cool. smile

Well we're all massless (Quarks are just energy, and the Higgs boson makes us have mass)

And Einstein's theory isn't wrong, we're just extending of what he started.

Its really cool seeing something go that fast.

Ok, for all you people debating whether time travel is possible in both directions: I know the arguments. This is more for entertainment purposes and to consider plot twists that could now exist.
