Will time-travel ever be possible?

Question

I know its almost everyones fantasy to turn back the clock or ahead, or fly, or become invisible.. one of the most closest to disbelief is Time-travel... what's your take??

Answer 1

I respectfully disagree that travel in time (forward and backward at will) is NOT possible.

Read Kip Thorne's conjecture about fishing 2 wormholes out of the quantum foam, enlarging them and holding them open with exotic matter (and negative energy), moving one relative to the other at close to the speed of light away from each other and then back again, jump in one, come out the other in the past! You can only travel as far back in time as to when the time machine was created to avoid the classical time-travel paradoxes.

To travel fast(er) into the future, just zoom your spaceship real close to the event horizon of a black hole.

Simply an engineering problem, what with exotic matter, negative energy, quantum foam fishing and zooming up to black holes!

Answer 2

Time travel is nonsense. Yes, space travel is fine, but will never be at speed of light. And what nonsense made us to believe that if we travel faster than speed of light, we can go in the past or in the future?

For example, if you want to see the future of the earth from the space, you would need to travel how many times faster than the speed of the light? And the location from where you are watching the earth will only give you an idea of how the earth was looking when that light had left the earth. Same as watching Andromeda Galaxy from the earth. You can watch it by naked eye, but the light which you are receiving now had left the Andromeda 2.2 million years ago. Also, by the time you receive that small fraction of the light, the source must have continued emitting the light..no matter when you receive that light..in 1 year..or after 1 billion years.

So, one way or the other, it will never going to happen...

Answer 3

Yes one can time travel through others' time scale but not through
one's own time scale - alone. And if you mean "The Time Travel" then it is a "no" because travel is physical but time is not. Time is
a human description based on the Sun being absolute. There are other systems in the known universal and human's time measure
will most likely not in sync with those systems.

So when you attempt earth's method of time travel you will hit a
time wall immediately. Compare travelling on earth and in space.
We need different methods. What will happen to a present spacecraft outside the solar system is still not known.

Answer 4

Well, you are travelling through time and space right now. Of course you are going "forwards", from the past into the future and beyond! (I had to put that there.) If you pick up the phone, you can call into tomorrow or into yesterday, if you are into tomorrow, by calling the other side of planet Earth. You can take a short plane trip across a time zone or two and arrive before you left, or be on the plane for an hour and somehow be hours ahead when you arrive. Oo, mysterious ain't it?

Time is connected to matter and space, if you can move fast enough, or slow enough, in theory you could alter this flow. Also you could possibly warp space and time using large masses and such. Might be easier than you think. All veteran astronaunts for instance are a tiny bit younger than the rest of us.

Personally I have trouble with time paradoxes.

If I go back into time, wouldn't I run into myself?

Also, I kind of wonder about the space trajectory. For instance, if I go forward or backward just a little in time, could the earth move right out from underneath me?

Could I have a dollar, go back in time and give myself that same dollar and tell myself to give these two dollars to myself when I will go back in time later, and repeat the process and be a billionaire within moments?

What if the next time around I went back in time with myself and repeated the process, what would I do with all the me's?

What if I go back in time and tell myself not to go back in time? Will I be there to tell me?

If I go back into time, change it, then go forward in time, back to where I started, do I get to pick which future to arrive in?

How do you properly dispose of an old flux-capacitor anyways? Can't just leave those things just lying about in time you know.

Here is something weird that no one talks about. If my friend lived from 1990 to 2050, but I left in a time machine in 2000 and arrived in 2050 and someone was to ask him in 2020 where I was at that particular moment in time, and he were to answer correctly, what would his answer be?

Answer 5

Is not fantasy! Have you heard of the Heisenburg Uncertainty Principle? It says that, theoretically, you can travel back in time, via a machine that utilizes the HUP. But here is the rub, it takes as much power as that generated by the sun, and once you make this time machine, you cannot go back in time any further than the day the machine came on line.
Unless...
You could map the n-dimensional folds of the space-time continuum in the vicinity of a black hole, discover in which fold the time you want to visit exists, then "fly" there in a craft that has a whole lotta horsepower that would allow you to navigate but still escape the clutches of the black hole.
But, once there, you could not come back the same way, necessarily. So pilgrim, you would have to map the vicinity of another black hole, and figure out in which fold your starting point was in the space-time continuum. And that might take a lifetime or be easy depending up the technology you have aboard you space-time machine.
My kids told me they were going to build a ship to take them to the sun. I told them that they would burn up. They told me not so as they would go at night.

Answer 6

Time is not real, it only exists in the human mind. Everything in life is based on a reaction which is or was caused by an action. There is no phenomenon that links this actions together in order to be reversed at once.
Example: We have day and night (human definition) because the Earth simply revolves around the sun, there is no mechanism set for it to do so, but simply an action that causes this reaction which only has a scientific explaination to it. By us (Humans) renaming today's date to an earlier date will not have any natural effect but to your schedules. It's simply an idea that helps us structure our lives that nature could careless about .

Answer 7

YES, i think in future science would have improved much than it is know may be some 1 will invent a time machine to travel.

Answer 8

Yes is will be possible. Actually if you have heard about mu mesons then you should know that that they are actually travelling through time as their speed is nearly equal to light. For now we have only got the technology to accelerate the microscopic particles such as electron so that they can acheive the velocity of light. For more details you should study the Einstein's special theory of relativity. In which it is said if you can attain the velocity of light you can travel through time. The famou twin paradox is result of only this theory.

Answer 9

My theory is that time travel will be invented, and then an hour later an undiscovered asteroid will impact Earth and wipe out all humanity -- which is why we've never seen any time traveling tourists.

Answer 10

i love this question, i always think of this question, i belive there is nothing impossible ,everything is possible, but in this case its not possible,imagine if humans start travelling to past or future , things go wrong which is against to nature , because people definitely try to change the past or future according to their convenience. better not to have such a journey
