Title: Time Travel
Post by: Cremator on September 21, 2014, 12:01:53 PM
I just read a thing about some guy who thinks time travel will be possible with in a few years. My question is, "if time travel were ever possible don't you think we would already know? I mean really.

There are two current theory for how time travel would be possible, the first is to travel at or near the speed of light. This causes time to pass more slowly for the person at light speed while everything else flows at the normal speed. The trip is one way though and only allows for the explorer to travel forward in time.
The second is one that I'm not as familiar with since it's a little more out there. Basically you take a black hole and wrap it around itself on an helical axis. This supposedly distorts space-time in such a way that a person can travel back in time, however they would only be able to go back as far as when the black hole was tampered with (assuming you would survive the spaghettification of the black hole).
Or you could always try to get your hands on one of these:

But the real question is will it lead to the same universe?
It could be just transporting you to a different universe where you land in a time earlier than yours... The biggest problem with using the blackhole as a "save point" would be that no actual information will make it through, only random.

Time travel has existed since the beginning of time.
It travels forward.

Most scientists who say time travel will be possible only think its possible to the future, never backwards. There would be an instant paradox if you would travel back in time. Those who think backwards traveling is possible, think that whenever you enter your past, you create an alternate dimension which has its new alternate timeline so that people in the 'original' timeline never see their lives changed. Anyone who enters the time machine just disappears for good.

MIT already disproved time travel. To date nobody has shown up to a time traveler convention.

Of course time travel is possible, but only if you are capable of living outside of time to begin with. You aren't, so forget it.

Who knows what the future will bring? Just look at the ignorance of only a few hundred years ago. Earth was center of universe, earth was flat, mermaids were actually dolphins and whales, and no idea what in heck the stars were. Even in the last 100 or so years we've made more progress since the 6 millions or so before that. If your in your 50's or 60's or older just look whats happened in our liftimes?
Men on the moon? Old news. The discovers of the universe alone have been astounding. As a young man if I wanted to call over sea's it wasnt much different then in the 1940's. Now? If your kid is stationed over seas you can play a video game with him and talk in virtual real time. Just the tech behind Aces High wasnt even dreamed of in the '60s. A kid joining the service now will in his lifetime probably see Hypersonic transport, quantum computers, evidence of life on other planets, incredible advances in medicine, maybe even AI.
Things seemed, and seem, impossible not because we dont have the answers but cause we havnt even discovered the questions yet. But If I ever get a ticket on that times machine there will be more then a few girls I passed up that will be getting a phone call.

Astronauts that return from the ISS are on average 9 seconds younger than people on earth due to their time slowing down. So time travel is being done as we speak. Just in small scale.

Parallel universe theory: Time travel is possible though existence is made up of innumerable parallel universes, in which we exist in all/most. Time travel is really jumping to an early universe.
Something like that....

That's relativity and not time travel. The closest thing we have for a theory that would allow time travel also involves wormhole theory. The problem with wormholes is figuring out where they go before you try to travel through one, but it is possible that there are certain flavors of wormholes that translate through time. The problem is just like I suggested that you have to be able to survive the trip, and as Hawkins suggested that a feedback loop would cause the wormhole to collapse if the trip is a local one (same universe/dimension). So, even if you can travel in time you can never influence your own timeline and probably it would be a one way trip where you can never report back your success, or failure.
It might make an interesting television program. TV audiences have a notoriously easy acceptance level of plot twists, so it could run forever if you do it right.

All time travel must follow the laws of physics so it doesn't matter if the time shift is caused by high speed or other phenomenon. It's still time travel.

No, it's relativity. Otherwise you could time travel just by taking a nap in a hibernation chamber.

I'm with you on this even though, technically, you are travelling through time in such a chamber just like I'm travelling through time sitting on my rump thumb typing on my 'smart' phone into this forum.

You can travel forward in time if you go close to light speed and take a nap in a hibernation chamber while doing it. Doesn't matter if relativity causes it. Time for you slows down and keeps on moving for the rest of the universe. If that's not time travel then nothing is.

No, you are a time-rider is all. Time travel as a term indicates that you leave the time continuum at one point and return at another. Your biology does not allow you to do that. You are trapped in time always riding the short duration of human life. You might appear to extend that time by travelling at near light speed, but it is not time travel.
You really are wasting your life arguing.

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 the 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:[30]
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[59] (see the Twin paradox)

That's time dilation Ripley, as described by the special theory of relativity. As I already stated, time travel requires leaving the time continuum at spacetime A and reentering the time continuum at spacetime B. Both examples you have given are time dilations. So, what's wrong is your understanding of the scenario. Even wiki indicates that there is little support for it in any factual sense as derived from theoretical physics. You might try philosophy next, as I understand that's where time travel has it's strongest support (mental exercise is required).

Time dilation is time travel, what's so hard to understand? It makes no difference what method is used, if your relative time towards the rest of the universe changes, you're travelling in time. Coincidentally the wiki lists time dilation under the paragraph 'time travel' so a lot of maintainers there seem to agree with me.

No, it's not. It's more of a distortion. You are trapped in time. You cannot escape it. Time travel requires escaping time at least temporarily. If you could actually travel in time, then you could visit time prior to your birth. You cannot, which serves to prove time travel is just a philosophical exercise, or science fiction. Pretending otherwise is just ridiculous.

Sorry bud you're confusing the time travel concept with traveling back in time. You don't have to travel back in time in order for it to be considered time traveling, traveling to the future is also time traveling - and also the only currently accepted possible form of such.

Time travel is theoretically possible ,which means it is possible only the problem is we dont have the engineering skills to build necessary stuff to do it (also requires alot of E). But it does not mean some other civilization has the same limitations with us... On the other hand think about if you could do time travel would you ever want to people in the time you are visiting know that you are from a different time ? nopee.... :evil:
