2. The Grandfather Paradox. If this creates an 'alternate timeline' then it's parallel universes, not time travel.



This isn't strictly true. It's still time travel into the past, but it's the actions in the past by the time traveller that creates the parallel universe.

Think of it like normal traveling, call Manchester the present, Burnley the past and Blackurn a parallel universe.

What you are suggesting is akin to saying that if you try to travel from Manchester to Burnley, you will end up in Blackburn without actualy reaching Burnley, in reality, it would be more like traveling from Manchester to Burnley but being unable to get back to Manchester because you could not avoid Blackburn.

Which itself isn't necessarily strictly true either, if the time traveler does nothing to change the past while he's there, then he should be able to return to the same future that he left behind.

my solution to the grandfather paradox
you would constantly move into parallel dimensions as you "changed" things. time would seem to realign itself in the sense that the problems you would cause would end up having solutions for them.

on another note.
if i went and killed myself before i went back into the future. i would still be there, in that parallel universe, i was just killed by my parallel self. theres nothing wrong with that. i still went there from another dimension where i successfully time traveled.

I prefer the way of thinking that says time travel is only possible in an era where the technology for it exists. i.e.

when time travel is invented that is point zero it's impossible to travel to before point zero as there is no reference point for the technology to "lock onto". So only forwards time travel is possible, or travelling into the past as far as point zero.

Quote by Jostry
If it were possible we would be having visits from our future selves.


logical fallacy; just because you haven't seen a visit, doesn't mean you can't visit, and it also doesn't mean nobody has visited

assuming somebody did succeed in creating a machine that can travel through time, the government would make it so illegal that it would be right up there with human cloning, due to the fact that going back in time could change history and therefore the present as we know it, causing us to travel through the parallel universes.

maybe they created an observation device.

also, just for shits and giggles:

Or someone discovered the time machine and went way back in time and built the universe how they wanted and that is what we are living in now...so the people in power are going to be in constant control.

There are time travel that suggest that not only is time travel possible, but we'd only be able to go back to when the time machine was first turned on. Also, scientists think its very possible to small particle back in time. If this were true people would be able to send small coded messages into the past. But once again, no further in in the past than when the machine was turned on.

It's true. Who would want to come to the 21st century? There are way cooler places and times, like the late Hadean eon or the Mesozoic era to see dinosaurs or ancient Egypt or whatever, all way better.
There's no such thing; there never was. Where I am going you cannot follow me now.

I'm saying this after not reading any other posts so sorry if it's a repeat.

If there was a time travel "machine," it could only go back to the point at which it was created. That in and of itself creates a problem. An ACTUAL theory is that once a time travel machine is created, there would be an infinite amount of people coming back in time to avoid the fate of whatever befalls them in the extreme distant future. If one supports a multiverse theory in which every possible thing ever has happened and for each of those possibilities another universe was "created," then maybe we're in a universe where we never discover time travel and another universe in the multiverse was destroyed instead. AND, if every action creates another universe with every possibility ever, then we don't have to worry about it because they'd go to another universe! Bleh.

Sorry for the run-on sentences but it gets a little crazy. Theories inside theories...theory-ception....

Well,imagine if a time machine was ever built, we could find a way to stop tragedies such as this.

Of course imo,just because the technology is not understood doesn't mean it cannot be done. Like people once thought that Nuclear energy could never be done.

It wouldn't be worth the risk just to speed up something that had already happened. There is no reason at all to speed up progress that happened in the past.

And if it's already happened, wouldn't your current present reflect the change that you are about to/already did make in the past?

ITT, people describe sci-fi plots as though they're theses.

New question. Which time travel is better? Back to the future time travel where you can create alternate time lines; or Bill and Ted (Time Traveller's wife) time travel where all the paradoxes are accounted for?

The first issue with time travel is demolecularisation. The final issue is remolecularisation.

Since we are currently incapable of remolecularisation, we simply do not have a conduit by which any time travel could be rebuilt on this side of their travel.

Thus, time travel is currently impossible.

The second one for real. It's the only really cool thing about Harry Potter.

Oh and Time Bandits. That movie ****ing rules! I'm not sure what kind of time travel that is.

Thus, time travel is currently impossible.

Currently impossible? There's seems to be something odd about that when we're talking about time travel...

Rowling also said that Dumbledore was gay for no reason whatsoever. I'm not sure her judgment is to be trusted in general.

For no reason? Read the books again, there are subtle things about him that mean it makes good sense that he'd be gay. Not least his backstory as regards Grindelwald.

I like to think he didn't really care about Harry defeating Voldemort at all and was just trying to get into his pants, er, robes?

"Oh, Harry, let me show you how to handle your magic wand..."

I got distracted and came back to this post. I forgot if I had a point or if I was just joking around at this point. Either way, I like the concept that any changes made to the past have already happened and led you to the point where you go back in time. That is you can change the past, but it has already been changed since it's the past.

Stop talking about Harry Potter guys. This thread's too good to be derailed.


OT: I heard demolecularisation and remolecularisation takes the energy of a sun to do.
So... time travel is pretty hard to do.

You say this like you know that time travel would work on a molecular level, and not a base energy level.
