What happens to time when traveling at or close to the speed of light?

When a frame of reference goes very fast (close to the speed of light) relative to a rest frame, its time slows down as observed by someone in the rest frame. This relativistic effect is known as time dilation. This relativistic effect is known as length contraction. The moving car actually gets squashed front to back.

Are we close to traveling the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

What would happen if you Travelled at the speed of light?

Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. So, traveling at the speed of light in the conventional way is impossible.

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.

What happens when we move through space and time?

The more we move through space, the less through time and vice versa. Everything travels through spacetime at the speed of light. Me, you, the cat (even Schrödinger’s cat), the Earth, the sun, bits and bytes, and any particles including photons (light particles). Note that I said spacetime.

When you travel at $C$ does the light move?

When you travel at $c$, the light still has to travel at $c$ wrt to you, but if the time is not going forward, there is no motion!$\\endgroup$ – Our Mar 29 ’19 at 9:05 Add a comment |
