If gravity slows light, would light be pushed faster away from a star that has less gravitational pull? Would we still observe it at c?
PaulRacer said:What about black holes?
Salbris said:I'm pretty amateur about all this but even I know that black holes don't slow light, they change it's path. The effect is called gravitionally lensing.
Now when it comes to light not being able to escape a black hole... I'm not sure why that happens...
Yes, light speed is faster coming from a smaller star. This is because smaller stars have less mass, which means they have weaker gravitational pull. Light travels at a constant speed in a vacuum, but it can be affected by gravity. Therefore, in a weaker gravitational field, light can travel faster.
The size of a star can affect light speed in two ways. First, as mentioned before, the gravitational pull of a star can slow down or speed up light. Second, the size of a star can determine its temperature and energy output, which can affect the frequency and wavelength of the light it emits. However, the speed of light itself remains constant regardless of the size of the star.
No, light speed cannot be faster than the speed of light, regardless of the size of the star. According to Einstein's theory of relativity, the speed of light is the fastest speed possible and cannot be exceeded. It is a fundamental constant of the universe and cannot be changed.
Yes, there are other factors that can affect light speed, such as the medium through which light is traveling. Light travels slower in denser mediums, such as water or glass, compared to a vacuum. Additionally, the frequency and wavelength of light can also be affected by factors like temperature and gravity.
No, light will always travel at the same speed within a given medium. While the temperature and energy output of different parts of a star may vary, the speed of light itself remains constant. However, the path of light may appear to bend due to the star's gravitational pull, giving the illusion of different speeds.
