I know we do not time travel right now ,but do you think we will in the?

Question

future?It seems the ideas we have come up with eventually come to pass ,even if it takes thousands of years

Answer 1

Time travel into the future is very possible: travelling a high velocity make time appear to travel more slowly for you - if you travel very close to the speed of light, many years can pass in the "outside world" whereas very little time passes for you, the difference being related to how fast you're travelling.

Time travel into the past is different. It is not expressedly ruled out by the physics of gravitation as they are known now. Take the mass of a typical neutron star, shape it into a hollow cylinder of length about one kilometer, diameter one kilometer, spin it so that the surface travels very close to the speed of light, and then go and stand near it for a time. According to some interpretations of modern physics, this will create a space-like path, which results in you emerging from the region of the cylinder earlier than you entered. It is very debatable, and obviously orders of magnitude more difficult that forward time travel. It is uncertain whether the physical conditions necessary are actually obtainable by any level of engineering humans will ever develop.

More prosaically, time travel into the past is considered improbably by many people for the simple reason of this: where are they? If people could travel back, why have we never met them? This is similar to the Fermi Paradox concerning alien life.

Answer 2

Physicist have theorized that a form of time travel may be possible using one of several methods. Ideas include faster than light travel, particular forms of spacetime geometries, wormholes, rotating black holes, and specific, if strange, effects of general relativity.

There is also a the possibility that the tachyon, a theorized but unproven particle, may travel at superluminal speeds and thus be capapble of some form of time travel.

However there is absolutely no proof that any of these methods would actually work and indeed there are several potentially fatal theoretical flaws in all of them.

The Wiki article on time travel provides an introduction to all of these ideas and a few others.

Answer 3

The simple answers would be we dont know, we can only speculate. People who say "No" or "Yes" with 100% certainity might be missing few things.

Let me talk about both scenarios

"No..its not possible" scenario:- People who say "No way" should realize that if you were to magically go back to 1000BC to tell someone that one day we will be able to go to moon, people would think you are nuts and gone crazy. But it has become reality today. We will never know what in store for us in coming 3000, 4000, or 10,000 years. Who knows.

"Yes..it is possible" Scenario:- Just because we can't say know doesnt mean we can say yes easily because we have to consider all the time travel paradoxes that comes up in the debate. You must have heard about grandfather paradox (where a person goes into past and avoids his/her grandfather to ever meet your grandmother. Thus, no generation and no you.) There are people who argue on this issue with another concept of parallel universe where, if you change the past, the events occuring from that point on will occur accordingly but in a different space time and that way you dont mess up the path (history) that already exists. It all might sound funny and crazy, but there are some interesting arguments and discussions in time travel debates.
So simple answer would be "we dont know". Probable but not certain with possibility.

Answer 4

I like the arguments against time travel into the past and about alien life.

1.) Maybe we aren't are interesting enough to visit.
2.) How do we know we haven't been visited? Maybe an alien looks like a flower or an alien device like a von newmann probe looks like an Ipod.
3.) Maybe time travelers or aliens came and went already?
4.) Maybe time travelers or aliens are actively avoiding us?

Anthropological arrogance is the reason we try to use 'where are they' arguments as a reason to claim something must not exist or is impossible. That arrogance does not determine fact - it only determines our perception of fact which often proves to be wrong.

Heliocentricism has roots back to 900 BC in India. Took us long enough to get back to that one here in the west didn't it? Why? Because we convinced ourselves we were that important - religion told us so. We like to feel important so we buy into ideas that support our egos.

Answer 5

With all the hot heads in this world,I don't think this civilization will survive a couple thousand of years.
Einstein's theory only projects time travel in the future ,not the past.

Answer 6

The best explanation of why it CAN'T happen came from a wonderful science fiction writer -- who wrote MANY time travel stories. But, he stated this:

If time travel were possible, it would happen, eventually. Then, we would use it to change the past. And keep changing it, and keep changing it. Until we finally changed it to a past -- where time travel was impossible! That is the only thing that would stop us from continually changing the past, so -- it must, ultimately, be impossible.

LOL!!

Answer 7

We'll travel forwards in time. As a matter of fact we already do...

As far as traveling back, science DOES think its possible. You just need a couple of black holes (connected by a wormhole), a Jupiter's worth of negative energy. A space ship that can travel near the speed of light carrying a black hole, and a pound of butter.

The pound of butter is for my wife, I forgot to get that at the store yesterday.

Answer 8

If time travel is invented in 1,000 years, then people in 3007 will be able to travel into the past, including back to 2007. So where are they? Since we don't get visited by people from the future, time travel must never get invented.

Answer 9

In thousands of years the guy would invent it,come back here and they would be all over the place in no time.

Answer 10

It seems that right now, not only time travel is impossible due to the fact that we are not yet so advanced in technology, but it seems that physics laws, especially quantum mechanics prevent this.
