Can we travel through time if we go at the speed of light?

Relative to yourself, you do not move through space, so these velocities are zero. You then only move into the time-like direction, and in this direction, you move with the speed of light. So, we indeed all travel through time with the speed of light.

What will happen to time if we travel at the speed of light?

The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. Still, there is one thing in the universe that is faster than anything we can conceive: Light.

Would you go back in time if you went faster than the speed of light?

Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.

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:

What is the speed of light according to Einstein?

Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second). Einstein’s theory of relativity says that space and time are linked together. Credit: NASA/JPL-Caltech What does this mean for time travel?

What happens to time when you travel at a certain speed?

Short answer: For one, the person traveling at such a speed would experience a slowing of time. For that person, time would move slower than for someone who is not moving.

Do clocks on airplanes and satellites travel at different speeds?

Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! We travel one year in time between birthdays, for example. And we are all traveling in time at approximately the same speed: 1 second per second.
