What happens to time at the speed of light?
Perhaps one of the most famous effects of special relativity is that for a human moving near the speed of light, time slows down. In this scenario, a person moving at near light speed would age more slowly. This effect is called time dilation.
Why do you age slower at the speed of light?
We do not age slower if we go at the speed of light but the time stops when we go at the speed of light. The reality is a object having a definite mass cannot achieve speed of light because mass is dependent on speed and when the object reaches near the speed of light we need infinite force to keep it accelerating.
How much time would pass if you traveled at the speed of light?
Thanks to Einstein, we know that the faster you go, the slower time passes–so a very fast spaceship is a time machine to the future. Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.
Can astronauts actually observe these as they travel at the speed of light Why?
That’s because, being a wave, light speed is independent of the speed of its source. And because the speed of light is the same for all observers (Special Theory principle) you can never catch it up. So yes you could still see where you are going.
Why does length contraction occur?
Length contraction is the physical phenomenon of a decrease in length detected by an observer of objects that travel at any non-zero velocity relative to that observer. Length contraction arises due to the fact that the speed of light in a vacuum is constant in any frame of reference.
How does time affect speed?
We know that an object, or a light beam’s, speed measures the distance traversed over time. Time dilation affects this reconciliation. Time dilates on moving vessels: the greater the speed, the greater the time dilation. Only when such velocities* approach light speed do such effects become significant.
Would you age if you Travelled at the speed of light?
How long will it take to travel 1 light year at the speed of light?
A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers. One might therefore conclude that in order to travel one light year at one tenth the speed of light, this trip would take 10 years.
Will humans ever travel at 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 happens when you go 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.
