Einstein called it spacetime/space-time. Feel free to submit your own scientific paper to credible journal(s) for peer-review.

@FearlessFly well mr physics why don't you explain how the speed of light is constant no matter what the velocity of the observer?

@JeffMesser . . . the one (in this case YOU) making the (extraordinary ? ) claim "no such thing as space or time. it's all a mental construct"
has the burden

@FearlessFly I just did. you just don't understand why. read more physics.

@Word @Allamanda @EdEarl . . . cute (maybe), but I'm hoping some might notice that this is the Academic (e. g. Science) group

@FearlessFly Of course, this group is about science. The pictorial renderings of the universe, with voids, galaxies, clusters and interconnections kinda remind me of the texture of lumpy cornbread, with big bubbles caused by leavening (voids), lumps of flour and cornmeal caused by insufficient mixing (clusters), cornmeal granules (galaxies), and flour holding it together (interconnections). I know my analogy is not scientific, but not everyone who reads posts in this group will be a scientist, and some scientists delve into the arts.
