Is time travel even remotely possible?

Answer 1

Time travel to the future is possible. All you need to do is accelerate to at a speed close to light's speed, then maintain that speed for a time, and slow back down. The acceleration is important so as not to make the special theory of relativity apply to yourself as seen from another point of reference. In the acceleration, you soon have a sort of "jet lag" effect, wherein your time measurement is slower than the outside world. When the trip is over, you would still measure time as you did when you started the trip, but the rest of the world had time move faster, and so in effect, you "traveled" to the future.

Time travel to the past, however, is so far not possible in the current framework of physics. This is because time itself only travels forward. Also, consider this example: Go back in time, kill your dad before you were procreated. The effect of this scenario would be that you were never born. If you were not born, you cannot go back and kill your dad. This would result to your birth, and the process repeats over and over again. This cycle can only be prevented if time travel to the past is not permitted by the universe.

Answer 2

Time "travel" is not possible, into the future or into the past. However, it will be possible to "see" the past. Imagine being in space on a spaceship and you're looking down to earth, what do you see? You see the earth in 2006. Now the reason you are seeing the earth in real time is because the speed of light lets you. Get it? The earth is an image and the speed of light sends the image to our eyes. So however the earth looked back in lets say 1995 the light is still traveling somewhere in space with that information. Light is still traveling in space with the way the earth looked in 1995. So if you somehow can go faster than the speed of light and "catch up" to the light with the information of the earth in 1995 then you can see the past. Pretty Simple.

Answer 3

In the sense of turning a dial and going to a given time and space, no. Not even remotely I think. There are just too many gigantic contradictions and paradoxes involved.

But on the other hand, relativity, confirmed now by observation of atomic clocks sent into space, reveal that time frames are indeed relative. Zoom off somewhere at incredible speed and hurry on back just as quickly and you will find yourself younger than your twin brother.

Not the same thing, but interesting.

Some of the obvious flaws/contradictions with the idea of time travel: 1) the idea of temporal/physical location. Suppose I went back in time to yesterday. Where would I be? I'd be in empty space, millions of miles from Earth which has blithely moved on through physical space. My scientific victory would be rather hollow. 2) the grandfather paradox. Going back in time, and changing a single aspect of the past would likely cause untold changes to the timeline. 3) if someday someone invented a method, people would doubtless use it to go back and witness famous moments in history. Those moments would become densely populated with future tourists...

Anyone who ever got a headache thinking about the plot of Terminator knows some of this: I mean, if he goes back in time and prevents the computer from taking over, then the computer didn't take over, which means he never went back in time to prevent it.... it all zeros out.

Answer 4

Probably so, but not in the sense most would perceive.

Theoretical, academic applications/excercises, but as you infer, doubtful.

If matter and anti matter are a vast consideration, think of the disturbance of the time line?

And it is a line.

Beginning, middle, and end.

That cancels out paralell universes as they should have to end with time when it plays out.

Then we have to think about something called eternity. Hope this helps.

Answer 5

Einstein's relativity shows that travel into the future is possible. Travel into the past is not.

Answer 6

numerous years in the past, Michael Creighton wrote a singular reported as "Timeline" about that very problem - time shuttle. it truly is the guy who wrote about a self-mutating virus (Andromeda rigidity) and we chanced on a scourge of AIDS. He wrote about cloning large animals (Jurassic Park) and we has Daisy the sheep. He writes about time shuttle... interior the novel, for the first time in SciFi heritage (or a minimum of in my reminiscence) time-shuttle wasn't only exceeded to us ala H.G. Wells or Robert Heinlein, yet changed into defined in a fashion that lent some credibility to the theory. you should study his rationalization...he talks about a Xerox and a fax and how transmitting coaching can bring about transmitting molecules in some thing reported as quantum teleportation (tele-transportation). it truly is what those transporters on "celeb Trek" are: quantum teleportators - they damage rely all the way down to the molecular element, despatched it someplace, and then re-carry jointly it. In Michael Creighton's novel, an unintended discovery in teleportation is the time shuttle. An twist of destiny. What i got here upon so brilliant, changed into that in his afterword, Creighton tells us that they have got already succeeded in utilising quantum teleportation. That by myself is astounding! Already performed? What next?

Answer 7

We all time travel every day. We move foreward in time at a rate of 1 second per second.

Answer 8

ye s i do it everyday i leave for work at 7:30 and get to work at 8:00 their fore i traveled 30 minutes.in time

Answer 9

I don't think so. Even if we find a way to create black holes and worm holes, or what ever, I don't think we will be able to control where we are going. And thats a scary thought.

Answer 10

I would love to believe that it was!!! I would love to go to ancient Egypt or fly ahead to 2080. But think about it...no. Not unless God took you. He is able.
