What happens to time as you approach speed of light?
In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop. Some people interpret this mathematical limit to mean that light, which obviously moves at the speed of light, experiences no time because time is frozen.
Why does time slow down as you approach the speed of light?
As light is spread out by the observer moving away from the source of the light time is decreased. The faster the observer moves the more light is spread out and time slows down. Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.
Does time slow down at the speed of light?
From the adoption of the postulates of Special Relativity, time does not slow down as an object approaches the speed of light, or any speeds. A specfic type of instrument designed to quantify time will tick slower when in motion (near the speed of light or otherwise relative to an observer (More on this later.)
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:
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 time dilate in a moving frame of light?
Since light is massless, we could call c “the speed of light”. But if light had mass, we might call c “the speed of gravitational waves”, or “the speed of the massless neutrino” (if there is such a particle). Since it turns out that c is not infinite, we can show from the Lorentz transformation that time does dilate in moving frames.
