After several months' work, I'm delighted to take you on an intergalactic voyage of discovery through space-time under all its forms! For an immersive experience, the video is best viewed on a large screen, in the dark, and with headphones or speakers.

@@kwimms "the religion of science" You're projecting. Just because your religion is religious doesn't mean that science is also religious. Scientists don't hold ideas to be absolutely certain. We hold things to various degrees of probable certainty depending on the evidence for the claim. In the case of relativity, gravity, and spacetime, our current models are, as far as we know, the best and most accurate explanation of reality. Perhaps one day we will have to modify our understanding - that's the process of science. Science deniers often act as if every time something new is discovered, that the entire puzzle board is overturned. That's not what happens. Science is like a jigsaw puzzle where we're constantly finding and adding new pieces, and though we don't have it complete, we have a basic idea of how the final picture looks. Every now and then we realize one of the pieces we thought was in the right place actually didn't quite fit as perfectly as we thought, and in fact there's another piece that fits better. But none of this changes the overall puzzle. Once in a great while we may realize after putting in a particular new puzzle piece that it actually changes our conception of what the final image would look like - but that's rare (Einstein discovering relativity would be an example of that). But again - the overall puzzle (which represents humanity's great attempt at explaining the natural world) remains in progress. It's not a perfect process but it's literally the only method humanity has to discover and explain reality. I mean, it sure beats "such and such ancient book says..."

Not to mention, the accurate representation of gravity and how it actually works, with the fabric being pinched and pulled inwards instead of the infamous ball-on-a-sheet example which is kind of misleading, other than the fact it's 2D. I've also never an animation so accurately depicting the formation of black holes. Take a bow!
