Time travel possible? Yes.

possible..yes..feasible..no

They are cute.

Hobbits can time travel, everyone knows that.

that is magic

I've smoked some stuff that made me feel like I traveled time!!

We're doing it right now, so it's absolutely possible.

When you look at a star, you're looking back in time.

I tried explaining that to someone once and got funny replies such that perhaps I'd gone loopy, lol. But it's true enough.

Remember him when you look at the night sky...


Night Rider!

I am the Night Rider baby...
A fuel-injected suicide machine....

haha that's pretty uncanny

It always takes time to travel. Are you fucking people on crack?

nope ., time travel is only a theory... time once gone doesnt comes back.

Nobody noticed that hobbit and the red army guy in the middle has same face?

I thought the black guy looked like Seal.

I am pretty sure I would of came back and told myself we can time travel if it ever happened... I am a dick, but not that much of a dick...

he came from past to present and he is making movies, cock shit

If we ever exceed the speed of light we'd technically be able to travel into the future.

i travel into the future. 1 second at a time.......

Everything is relative

Everything is realtive

Time is relative. Time is also a human concept, where the ground unit, one second is defined as 9192631770 periods of the radiation which equals the transition between the two natural states of the Cesium 133 atom.

These transitions can be almost halted, by bringing the cesium 133 atom to or very close to the Absolute zero, which is 0K on the Kelvin scale and as −273.15°C on the Celsius scale. Then we can reach an interesting state, agreed on an academic level, where 1 second, by its definition becomes longer, because the periods of radiation will decrease and thus take longer to accumulate to 9192631770 periods. So if one could totally stop the downfall of the Cesium 133, you would, by definition, also stop time as humans know it. Natural time would still go on, the earth would still spin and day would become night somwhere on the globe. At least everyone expects life to go on as usual, but in theory, since the definition is stopped, the whole world could also potentially come to a scretching halt.

It is, to this date, still very uncertain if the downfall of the highly radioactive Cesium 133 atom actually can be completely stopped or only slowed down.


On the other hand, we have light. Natural light travels at a speed of 299792.458 km/s (186000 miles a second, from Earth to the Moon it's roughly 239000 miles). If you could somehow transport yourself at the same speed, it would look like the rest of the world stood completely still. The light emanicipated would travel with you all the time, kind of following you and it would be like if you never moved but remained in the same spot. To everyone else, you would be moving incredibly fast, but from your own view, the world would be like frozen.

Now, if you could transport yourself FASTER than light, you would be able to be in Position A and watch the touchdown there, then get into your time capsule and travel for one minutes, at twice the speed of light, get out in Position B and in one minute you would be able to see the images, such as the world happened back in Position A three minutes ago.

It is today unclear where Position B exists, if it even does exist. It could be an empty future, just waiting for our light in this very moment to come in and fill it, there are also theories of a parallell universe and so on. This is what is usually referred to as time travel, to actually travel faster than the speed of light and thus already be there, when the light reaches that exact spot and then see what happened "back there". However, this creates other problems.

It is likely, that nothing created by humans has ever been able to supercede the speed of light and remain a stable mass. Some claim this is proof against time travel, others say "give it a few more years".

Remember, everything is realtive. The only thing that matters is whose perspective we use.

Yes everything is relative, and it's actually the fact that nothing can ever exceed the speed of light that allows time travel into the future. If you were able to travel close to the speed of light, say 90% in a magic train or spaceship then time "for you" slows down relative to the outside. The closer you get to the speed of light, the slower time "for you" becomes and the faster you are traveling into the future. If you were in a very long train that was traveling very very close to the speed of light, in theory if you were able to propel yourself through the train then your speed + the trains speed could exceed the speed of light, BUT of course that law of physics can't be broken so time would slow to compensate, if needed you would be completely frozen in time.

The shit is getting deep up in here.

Actually these things happen all the time, now, in the real world but on such a tiny tiny level that we'll never notice them, only at a universal level do they have any real significance.
Example 1, set two atomic clocks at exactly the same time, give one to Priya Rai and put her on a flight around the world non stop. Give the other to..... me and then when me and Priya meet up the clocks will be out of sync, Priya's clock will have travelled into the future, all be it millionths of a second.

Example 2, Alexis Silver is oiling up her boobs 10 meters away from me and that damned annoying Priya Rai that can't leave me alone is masturbating 50 meters behind her. Although I can see both of them together, neither of them are actually in the same time as me, both events happened at different times in the past. Again millionths of seconds.

woah I guess it does exsist!

Yep speed of light is fixed, constant and can't be beat, that is reality.

Awesome post, man.

It depends on perspective as you said. But also, how susceptible is the perceived phenomenon to the Heisenberg Uncertainty Principle?

Is that Samuel L. Jackson on the right?

80 magic mushrooms and you are very close ...

And Kevin Bacon in the middle...

Freezing anything to absolute zero stops atomic movement in whatever you are freezing but does not slow time.

If you were flying at 186,000 miles per second to "catch up" to the speed of light, light itself would not appear to freeze in time. It would still move along, at 186,000 miles per second, relative to you. Only the appearance of time as viewed from your point of view would appear to slow down. This is called Einstein's Time Dilation effect, and is described in his "Twin Paradox" theory.

There's 2 ways to travel to the future.

1
Cryogenic suspension. That's easy, over 100 frozen corpses are already in liquid nitrogen, most of the recent ones used anti-freeze so there were no fractures in the brain tissue. Reanimation isn't perfected yet, but a microwave rotissery should do most of the reheating.

2
Approach the speed of light, about 99.9% as fast in a space ship and you go into a kind of hyperspace! Not only does time slow down, not much light will catch up to you from behind, so from your perspective you could fly across the galaxy in a couple weeks and all the stars would zoom past the front of the ship and to the sides, but behind the ship would be pitch black!

If you accelerate the space ship at 1.2G, it takes 6 weeks to approach the speed of light, then you have to decellerate as well for another 6 weeks.

Using conventional Newtonian physics, you would need an ION drive where the exhaust fumes were ejected atleast 50% the speed of light, and atleast 99% of the space ship would be fuel for a 2 way return trip back to Earth.

TO TRAVEL TO ANOTHER STAR

START --1.2G for 6 WEEKS --> 2 weeks hyperspace --1.2G for 6 WEEKS to slow down --> ARRIVE

Your space ship 1/3 the original weight to reach hyperspace, and 1/3 again to slow back down.

So a 2 way trip, assuming you can't refuel at the remote star, your space ship would be 1/81 it's original weight on return to Earth. i.e. 4 trips, each trip you need to exhaust atleast half the ships weight at close to the speed of light to approach the speed of light yourself. So 99% of the space ship must be super-efficient fuel. PRACTICALLY IMPOSSIBLE TO MAKE A RETURN TRIP. Robots might do it though.

and when you return from a star 1000 light years away, Earth will have advanced 2000 years... but you will still be young... standard twin paradox

look at all you atomic scientists in here

And you'll then be able to tell those future people on Earth (if there are in fact any left) what the star you just visited looked like . . . one thousand years before.

That's sure not the way James Tiberius Kirk envisioned space travel.

we are time traveling right now, you just don't notice it.
