Debtor: Would someone care to explain to me why would an object go back in time when it travels faster than speed of light. What makes time slow down if you go at higher speed? Why you can't go faster than the speed of light? Why people think that a black hole is way to some other dimension than astral planes of Heaven? Why no one ever wonders if mr. Einstein might have been wrong with some of his theories? Or why no one has ever thought that Einstein himself was a time traveler, who went back in time just for lulz, making up fake theories that all physicists in the world follow for centruaries?

I was going to take your question seriously until that part. =(

DarkWater: Wow, you're not very bright at all. We specifically said that if one person leaves for x amount of time in a spaceship traveling near the speed of light, their watch will show that less time has lapsed compared to an observer who stayed on Earth (whose watch would reflect the amount of time the space-traveler was gone). And by the way, there is no way to make a person who is on Earth and a person who is a near-speed-of-light spacecraft spend the "same amount" of time after you account time dilation because time is always passing at that same constant speed on Earth. Seriously, stop now. What an ass.


Ok, learn to read because I have to repeat everything in order for you to understand. A person leaves for an x amount of time in a ship near light speed. After time dilation is accounted for, their relative time compared to that of time's passage on Earth is different. However, when normalized to either perception of time (be it that of the speed of light's or that of Earth's), the amount of time that passes on Earth is x but that which has passed in light speed is no longer the same x amount, it is a new amount y after td is accounted for meaning that the same amount of time has not passed. Same is as blunt as I can be in trying express the concept of equality, so when I say the same amount of time passes on earth as in space, I refer to the normalized values of time after td is taken into account. This is the second time I've had to explain this, I'm wagering that it'll take another six or maybe seven for you to comprehend.

It is impossible, Einstein has already proved that time travel as a medium is impossible, however he did prove that viewing the future but not actually going there is theoretically possible. Now if you choose not to believe one of the smartest physicists ever then go ahead but I sure do. TIME TRAVEL IS IMPOSSIBLE

The fact that they have two different amounts of time is completely due to time dilation; you can't "normalize" the time based on time dilation. Here:
Let's say someone leaves earth at 1:00PM at nearly the speed of light. An observer on earth is wearing a watch and records the time that the astronaut left and the astronaut, also wearing a watch, records the time as well. He travels for two hours (earth time) and then comes back. Now, for the purpose of this little anecdote, I'm going to EXTREMELY exaggerate the effects of time dilation. When he returns home, he sees that his watch reads 2:37PM while that original observer's watch actually reads 3:00. In the amount of time that it took for someone on earth to travel 2 hours forward in time, the astronaut only traveled 1 hour and 37 minutes forward in time. He is 23 minutes younger, comparatively, than he would have been if he stayed on Earth.

You can't normalize the time. At that ratio of 120 minutes:97 minutes, if you wanted the astronaut to go 120 minutes in his faster time, the person on would have spent 148 minutes. The cycle just keeps continuing.

I think it would be fun but it could mess things us severely. It would also teach people that it doesn't matter what you do, you can always fix it.

It might be possible that they already discovered time travel in the future, but they don't use it because they know that it will destroy the balance of the universe.

Normalize time's value, not time itself. From your anecdote, there is a 23 minute difference in the amount of relative time that passed between the space guy and the earth guy. Obviously three Earth hours in not the same as three earth hours in space, as in space three earth hours translates to two hours and thirty seven minutes on earth. To normalize this value, the value to which I refer to as the same amount of time having passed, simply take the value of earth time that has passed since 1:00PM to 3:00PM and compare it to the same converted time that would pass in space. This is the normalized values for time that has passed, not time itself. Were an observer to have spent an x amount of earth hours on earth, the same amount of time in space would by yx earth hours where y is the multiplying factor of earth hours required to normalize the values of time spent in space and earth.

Time travel is theoretically possible if you surpass the speed of light.

The concept of traveling to the future is more plausible than traveling to the past. Scientists have found ways to bend light, which inadvertently speeds up time. Kind of like how air traveling over an airplane's wing travels faster than the air flowing under the wing.

Tehidden: Hahaha. Time Travel? Where's the "It will never happen...ever" option.


how about "It has already happened...in the future"
