I heard, if your travel faster than the speed of light, you would never physically age. True?

Answer 1

True? Can anything so theoretical be true? I don't think even physicists can agree unanimously on this one.

But I think this theory is increasingly being rejected by most experts in the field.

Answer 2

As you approach the speed of light, you begin to age slower. Einstein said you are always traveling the speed of light through two dimensions, the space dimension, and the time dimension.
The faster you travel in one, the slower you travel in the other.

If you were to travel the speed of light in the space dimension, you wouldn't be moving at all in the time dimension. This is one of the reasons you can't travel faster than the speed of light. Theoretically if you could travel faster than the speed of light, you would be going back in time.

There is a theoretical particle called a tachyon, that travels faster than the speed of light, and is going back in time.

Hope this helps.

Edit- There is also a paradox about this, called the Twin Paradox. It goes like this: There are two twins, and one decides to go on the trip. During his trip he is traveling closely to the speed of light, and returns a year later (relative to the twin who left). When he comes back, his other twin has aged 50 years, but he has only aged 1. This has been proving by having a clock on earth, and one sent into space. When the clock returned it had experienced time more slowly.

Answer 3

Nothing can travel faster than the speed of light. If you were to travel very close to the speed of light, people will see you age very very very very slow. For them, you will not age at all, and for you, you will see them age very fast.
In other words, your will feel only 60 years passed in your frame, but in other's people frame you have lived 400 years. You still have aged.

Answer 4

Until know, nothing can reach the speed of light, even less, more than that. As closer you get to the speed of light, as slower the time runs. At light speed the time is not running anymore, with faster then light speed moving, theoretically, time runs backward

Answer 5

Time stops when you go at the speed of light for OBSERVERS of you, not for you yourself (according to the theory of relativity anyway).
Of course this presupposes that one can not ever reach the speed of light as a body increases in weight as it gets close to the speed of light, getting infinitely heavy and ergo infinitely hard to accelerate as it approaches that theoretical limit.

So if you travelled at 99.9999999999% of the speed of light for (say) 1 minute - time wont stop for you...you will age a minute. BUT when you slowed down hundreds of years would have passed for those who werent travelling at the speed of light with you.

Sadly, there is no free lunch, nor elixir of youth in speed travel :'(

Answer 6

traveling at the speed of light you wouldnt age, faster you would start moving back to zero. i wouldnt worry too much about this since traveling faster than c is impossible.

Answer 7

no. time will not change no matter how fast you go.
and its theoratically impossible to go at the speed of light, or even above it.
just imagine this.
a train moving forward closer and closer to the speed of light will have more carriages attached to it(yep, this is true, mass increases with an increment of speed and no change in potential energry). So to make it go faster and faster, you will need infinite energy.

Answer 8

faster than light is not possible.

as you approach the speed of light, time does slow down for you. you age at the same rate, but your 5 yrs could be a hundred years to people here on earth.

Answer 9

you can't travel faster than light

Answer 10

False.
