The speed of light is a fundamental limit in our universe, and according to our current understanding of physics, nothing can travel faster than the speed of light in a vacuum. The expansion of the universe, as described by the theory of general relativity, occurs on a cosmological scale and affects the space between galaxies, causing them to move away from each other.
If light were somehow able to travel faster than the speed of expansion, it would still be subject to the speed of light limit. Light would continue to propagate at its maximum speed, but the expansion of the universe would cause the distances between objects to increase over time. In this scenario, it is unlikely that light would escape the universe because the expansion of space itself would carry the light away from us, making it increasingly difficult for us to detect.
It's important to note that the concept of "escaping the universe" is not well-defined within our current understanding of physics. The universe, as we know it, includes all of space and time. The expansion of the universe refers to the stretching of space itself, rather than objects moving through space. So, while light may not escape the universe, it can still travel vast distances within the expanding space.
