>The idea that space and time are actual objects, instead of intellectual constructs, has always struck me as wrong. There were similar objections to the existence of the electromagnetic field, back in the 1890s. But it turns out that fields can propagate energy independent of any non-field objects in them... and if it can carry energy, then how can you say they aren't real? Spacetime carries energy in the form of gravitational waves. So it is as much an object as anything else that carries energy, whether it be in wave form or mass form.
