At speed of light

What will happen if we travel at the speed of light?? Will time stop there as it is seen that as we tend towards the speed of light it slows down!!!!

Of course photons do not have mass. Photons constantly strike all particles in our surroundings including our eyes.If they had mass we'd all go blind. At such a huge speed of light even a small amount of mass will lead to a huge amount of energy. Regarding the question of us travelling at the speed of light , time won't stop. even light takes its own time to travel distances.

Because we have mass, it is physically impossible for us to travel at the speed of light... Hypothetically an object travelling at that speed would not experience time or distance (because of the Lorentz contraction effect). To an outside observer they would have "stopped in time". But this is impossible to apply in a situation of "travelling at the speed of light" because that is itself impossible (the energy required to accelerate any massive object to c would approach infinity).

Hope this helps!

what happens to the radio waves?????????

It is possible ....Of course , if we travel at the speed of light then our body is compressed along your direction of motion. If you're standing the right way, it'll look like you've lost weight and that your body has been flattened under a giant stone. Because of these perspectives Will time stop

SPEED OF LIGHT IS 9 *10 k power 28 per sec

ok so as the radio waves travel at the speed of light they do not have any kind of time in them!!!!!!!!!!!!!

I think it is simply impossible.

As you approach the speed of light, time will slow down for you as compared to an outside observer (although to you, time seems to be passing at a normal rate), and if you reached the speed of light, time would apparently stop. This does not necessarily imply that time would run backwards if you could somehow actually travel faster than light, however.

It's a moot point anyway because you can't travel at the speed of light (or faster than light). Your mass becomes infinite as you approach the speed of light and it would take an infinite amount of energy to keep accelerating, and there is no way to create an infinite amount of energy. Only massless particles like photons can travel at the speed of light.

Radiation pressure is a result of momentum, not mass. If photons have zero mass and travel at the speed of light, then the gamma factor is indeterminate, producing a finite momentum. p=E/c= hf/c

I suggest you to read about the twin paradox, and try only to extrapolate speeds close to the speed of light.
