Why can we never break the speed of light?
The speed of light in a vacuum is an absolute cosmic speed limit. According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move. In order to reach the speed of light, you’d need an infinite amount of energy, and that’s impossible!
What would happen if light moved faster?
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.
Why is light speed the limit?
But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
Why is light speed infinite?
That something, the universal conversion factor, is the speed of light. The reason that it is limited is simply the fact that a finite amount of space is equivalent to a finite amount of time. Were there an infinite value for the speed of light, light itself would not exist at all.
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:
Why does light travel so fast in a magnetic field?
A magnetic field cause the attraction between the North and South poles of a magnet. In light, the strength of these fields changes with time and place. How fast this wave changes with time and place determines what color the light is. I can’t tell you why light travels so fast.
Does time slow down when it reaches the speed of light?
For a person travelling very close to the speed of light with velocity $v$ from the sun towards the earth time does slows down, and he goes past the earth in a matter of seconds.
Why does time freeze at the speed of light?
The reason some people will say that time freezes at the speed of light is that it’s possible to take two points on any path going through spacetime at less than the speed of light and calculate the amount of time that a particle would experience as it travels between those points along that path.
