I sort of get the idea of how nothing can go faster than the speed of light but it always bugged me in the back of my mind and seems like it shouldn’t be how the universe works
In: Physics
Light does have variable speeds!.
Light changes speed depending on the medium it is traveling through so as we break this down your doubts are becoming more valid.
Then, we could say the speed of light is relative to the observer so it is likely possible light is much slower in certain parts of the universe depending on the observer and environment. so, technically it does have a variable speed and your logic seems correct.
Speed of light is relative to the observer. If you could take a rocket with a headlight and moved it at the speed of light it would appear different to someone on the ground than to someone on the rocket.
Speed and time are intertwined in ways you cannot eli5.
The speed of light is actually infinity if you look at it in a certain mathematical way. It actually can’t be any faster. See this video: [https://m.youtube.com/watch?v=vPi1lyAx4ws](https://m.youtube.com/watch?v=vPi1lyAx4ws)
