- TL;DR Summary
- Two sets of questions (time and c) – maybe fundamental, but probably naive...
The faster the relative speed or the more intense the gravitational field, the slower time passes. Does it make sense to ask what both have in common that affects time? Or does the question possibly only make sense in the context of certain theories, for example the LQG, where space and time arise through the interactions of gravitational quanta?
Is it a coincidence that both electromagnetic waves and gravitational waves move in a vacuum with the speed c? Is there an underlying cause? Is the reason for this a fundamental property of spacetime or space quanta or gravitational quanta?
