Is it possible to travel at the speed of light?

Yes, I agree with David. If somehow, you were able to travel at the speed of light, it would seem that ‘your time’ would not have progressed in comparison to your reference time once you returned to ‘normal’ speeds. This can be modeled by the Lorentz time dilation equation:

Is time frozen at the speed of light?

This answer would be undefined or infinity if you will (let’s go with infinity). The reference time ($T_0$) divided by zero would be infinity; therefore, you could infer that time is ‘frozen’ to an object traveling at the speed of light.

Can we move relative to light?

In essence, there is only one “Light” and we are all in the exact same location relative to it. When we measure the speed of light we actually measure the speed of the propagation of light, the light never moves and has no speed. You also can’t move AT ALL relative to light.

Does light travel through the universe at the exact same time?

If from light’s point of view time is frozen (I agree) then the light passes each point in the universe at the exact same time. In essence, there is only one “Light” and we are all in the exact same location relative to it.

The idea of travelling at the speed of light is an attractive one for sci-fi writers. The speed of light is an incredible 299,792,458 meters per second. At that speed, you could circle Earth more than seven times in one second, and humans would finally be able to explore outside our solar system.

What happens to mass when an object travels at the speed of light?

You see, if an object travels at the speed of light, its mass will increase exponentially! Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite.
