Could it be possible for light to not move at all but remain still while space and time moves past it? The light would just exists as the continuum of space time moves past light.
Said sun and stars would be moving with space time as wellRada Demorn said:Impossible.
By your definition we would have collided with the Sun or any Star which emits Light a very very long time ago.
But could it be that position is what is really moving.PeroK said:The definition of motion is a change in position over time. By this definition, light moves.

A star emits light in all directions.Troymteal said:Said sun and stars would be moving with space time as well
There is no inertial reference frame where this is correct. You could construct a non-inertial coordinate system where this is correct, but the laws of physics would not be what we are used to at all.Troymteal said:Could it be possible for light to not move at all but remain still while space and time moves past it?

You have heard that the universe is expandingRada Demorn said:A star emits light in all directions.
Which way would your poor star move then? Every direction?
We have, and in our cosmology section you will find many threads discussing what this means.Troymteal said:You have heard that the universe is expanding

A mirror or worse an infinity mirror would also appear to cause problems.Vanadium 50 said:Imagine two light beams moving past each other. Are you arguing both are stationary and space is moving past them in two different directions?
The theory of relativity, proposed by Albert Einstein, states that the laws of physics are the same for all observers in uniform motion. This means that the speed of light is constant for all observers, regardless of their relative motion. Therefore, the movement of light is not dependent on the movement of space and time.
The speed of light, denoted by the letter 'c', is the fastest possible speed in the universe. It travels at approximately 299,792,458 meters per second, which is about 670 million miles per hour. This is significantly faster than the movement of any other known object.
According to the theory of relativity, light does not have mass. Its movement is purely based on its energy and frequency. However, it can be affected by gravitational fields, which can change its direction and wavelength.
No, the movement of light is independent of the movement of space and time. Light always travels at the same speed, regardless of the observer's perspective or the speed of their movement. This is a fundamental principle of the theory of relativity.
Space-time is a concept that combines the three dimensions of space with the dimension of time. According to the theory of relativity, the speed of light is constant in all frames of reference, meaning that it is unaffected by the movement of space-time. This concept helps explain the movement of light and its ability to travel vast distances in a relatively short amount of time.
