Boltzmannbrain Posted February 8, 2023 Share Posted February 8, 2023 46 minutes ago, Lorentz Jr said: Why is this thread in the Relativity section? The question is profoundly speculative, and there are nontrivial answers associated with other theories. If anything, relativity seems to inherit the classical model of space as an empty void that particles move through, only acknowledging that it can be curved and not that it can be made of anything that has a state of motion. But doesn't it "expand" and "contract" at the speed of light? That is kind of like moving isn't it? Link to comment Share on other sites More sharing options...

But the principle of relativity states that space doesn't have any "parts" or "constituents" that could have a detectable velocity, which is a property that's normally associated with things that are "made of something".
