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
If light was a different speed, it would mess up the formulas that use the constant c e.g. E=mc^2. Suppose light was slower. Maybe stars would always collapse because fusion wouldn’t provide enough energy for them to overcome their own gravity. Or maybe if light were faster, stars wouldn’t form at all because they would blow apart from too much energy.
