If you mean, shouldn't light be everywhere at once... then no. Time only slows down for matter traveling close to the speed of light. And by 'slows down', I mean it's only slower to stationary observers watching the speeding matter. To the speeding matter everything is business as usual, but the universe looks a little different. You start to notice things like time dilation (the universe around you seems to speed up) and space flattening (the amount of space you travel through to get places seems much less).

So, to answer your initial question, to a stationary observer, what's going on in a light ray may seem stopped, but the speed the light ray is traveling is measurable. The cool thing about this is, since time is stopped for the photon compared to the rest of us, they never age. That's how we can observe the light from galaxies that are 10 billion light years away.

Its true if you travel faster than the speed of light that you may travel to a whole new dimension?

No one can tell. Our current understanding of physics and how the universe works pretty much stops at light speed. So what would actually happen if you managed to perform the impossible - go faster than light - no one can tell.


If time stops at the speed of light how do photons move?

Time for the object or person in question stops. This does not affect the objects around which aren't travelling at that speed or the region of spacetime which is around them. A simple and possible explanation is that time is stopped for the photon, but this stays unnoticed because we are not moving at that speed and so we cannot say what is happening to the photon.


How fast are you moving on earth standing still?

At what are called relativistic speeds (some 90% the speed of light and more), time slows down appreciably. At the speed of light, time stops. But as anything with any mass is accelerated near the speed of light, it gains mass (because the energy being put into it to move it is converted into that mass). Just so you know what 'Big Al' Einstein said.


Is relative speed of light constant?

The speed of light in a vacuum is absolute, unchangeable and can't be exceeded. The speed of light anywhere else depends on the material it moves through. c is indeed the c in e=mc2 - it is also the speed of light in vacuo. Any material has a speed of light associated with it, but that speed is not c, and that speed is neither a fundamental constant nor a universal speed limit. Photons are limited to that speed while in the material - that is what causes refraction. Material particles (those with mass) are not subject to the speed limit, any more than a rifle bullet is limited by the speed of sound. When a rifle bullet passes close to you, you hear a crack; this has the same origin as the sonic boom from an aircraft going supersonic. If a material particle that is travelling at close to c enters a material where the speed of light is less than the speed of the particle a shock wave is generated which is closely analagous to the sonic boom. There is no sound, just electromagnetic radiation, known as Cerenkov radiation. If you ever get a chance to observe a University reactor, almost all of which are water moderated, look down into the pool and admire the beautiful blue-green light surrounding the reactor core. That is Cerenkov radiation, caused by particles produced by the reactor going faster than the speed of light in water. As the particles bleed off energy into e-m radiation, they slow down. Once they are below the speed of light in water the Cerenkov production stops. It normally takes only a few feet.


Traveling at speed of light how much time will pass in 70 years on earth?

None. At the speed of light, time stops completely. It is impossible for anything with an invariant mass to move at the speed of light; only particles with no "rest mass" (such as photons) can do so.

Why you cannot travel faster than light?

Because when moving at the speed of light, time stops for you and you can no longer measure speed (distance covered in a certain time).

Wouldn't an object moving at the speed of light relative to other things in space technically be at rest relative to itself and always allowed to accelerate?

It would be if it wasn't for the fact that time relative the object moving at high speed slows down as you approached the speed of light, and completely stops when you reach it. This is what prevents things from going faster than the speed of light.


Why can't you achieve light speed?

You need to know the Einsteins equation of relativity. t'=t(1-v2/c2)0.5 Basically this says the time (t') is relative to velocity (v). And C is the speed of light If v=c you get: t'=t(1-1)0.5=tx0 Therefore time stops for you when you reach the speed of light.


Why do scifi spaceships always have a maximum speed of x percent for example 50 percent or 30 percent of the speed of light what stops them from accelerating to 99 percent without air resistance?

Even at modest %'s of the speed of light objects start to radiate their energy away in Gravitational Waves. So it is very expensive to approach the speed of light when most of your effort is just radiated away.
