Poll: Is Time Travelling Real?

Simple question, tough discussion. Discuss.

Technically yes but no one can ever achieve it ever.

Mzd

Yes, just not in this galaxy

Changes

Only in Back to the Future.

Ewan Chaos

Eh I don't think so. I think if it was then someone would have screwed up by now and gone into the past to mess something up by now.

I think it's very real because to me, time can be bent in many directions.

Explain please. I didn't know someone could have any sense of idealism to vote for this fascinating option.

If this was true, why the **** do you think we waited 10 years to finally find Bin Laden?!?!?

Well since we've establised that those pesky neutrinos didn't do it, I'd say it's safe to assume it's impossible. Travelling at speeds above that of light is the only way to scientifically do it.
And don't try to talk about tachyons, they're only hypothetical and couldn't be utilized even if they were real.

Or possibly taking wormholes but we haven't come into contact with any to test what would actually happen and whether it really works.

My idea of time travelling is of a scenario in which future civilization would travel back in time unaware that they have concluded in a parallel universe. My theory is that the same chronology of reality cannot co-exist.

Lee!!

Yes I've spent time in the TARDIS!!

FAN

I wish.

Vato

It is theoretically possible to travel to the future (but not to the past). I say yes

ABEL-o-matic

That's a great theory Papi Vato.. Because people are so caught up with saying that you need to travel faster than light to time travel. I believe this is very real if you're only interested in travelling to the future. But to travel back in time, it disagrees with the "faster than light" theory because if you want to travel back in time, you will need to REVERSE the chronology of reality, which means you're reversing the SPEED of light - going slower than the speed of light. And it that sense, travelling back in time is flawed.

I actually remember reading something about a plant or light force or something being able to speed up time

Here it is:

Time travel to the future in physics

Twin paradox diagram

There are various ways in which a person could "travel into the future" in a limited sense: the person could set things up so that in a small amount of his own subjective time, a large amount of subjective time has passed for other people on Earth. For example, an observer might take a trip away from the Earth and back at relativistic velocities, with the trip only lasting a few years according to the observer's own clocks, and return to find that thousands of years had passed on Earth. It should be noted, though, that according to relativity there is no objective answer to the question of how much time "really" passed during the trip; it would be equally valid to say that the trip had lasted only a few years or that the trip had lasted thousands of years, depending on your choice of reference frame.

This form of "travel into the future" is theoretically allowed (and has been demonstrated at very small time scales) using the following methods:

Using velocity-based time dilation under the theory of special relativity, for instance:
Traveling at almost the speed of light to a distant star, then slowing down, turning around, and traveling at almost the speed of light back to Earth

Using gravitational time dilation under the theory of general relativity, for instance:
Residing inside of a hollow, high-mass object;
Residing just outside of the event horizon of a black hole, or sufficiently near an object whose mass or density causes the gravitational time dilation near it to be larger than the time dilation factor on Earth.

Additionally, it might be possible to see the distant future of the Earth using methods which do not involve relativity at all, although it is even more debatable whether these should be deemed a form of "time travel":

Hibernation
Suspended animation

I voted for the second option.

ABEL-o-matic

Thanks Tia! I'll definitely read this.

Vato

Plus, travelling to the past introduces several paradoxes and complexities that would make it impossible, even theoretically.

My physics professor in college was hardcore about this particular subject, and he explained it all in detail during his classes. It was fascinating tbh.

I want to know more about your professor's theory!

Could be.. I heard some people claim we have already lived this life before we just living in the present revisting it

that could b a reason for dejavu
