What if we could see Spacetime? An immersive experience

[@mchevre]

@@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..."

Fabulous video as always, one correction though: At 6:25 its shown that if someone jumps through the earth, they'd come out on the other side. What actually would happen is they'd accelerate from 0 to some max velocity till reaching the center, and after that start decelerating in the same fashion, and by the time they reach the other side their velocity would be 0, and then back again and they'd be oscillating And practically I'd assume with some drag the oscillations will dampen right? Some few hundred years and the person would settle in the center. The whole setup is analogous to letting off a marble at the edge of a bowl, but instead in a one dimensional motion in this case

I live in a third world country where the people do not have basic amenities talk more of being able to afford them. I am educated, by the standard of my country at least, and concepts like space and time are spoken about in physics and chemistry classes but they're never really put into perspective for people to grasp. I started using the internet at an early age of 9 and as such, I was exposed to the nature of the world around me. I'm currently in my early twenties and I've realized that it's not just the people in my country that do not get the bigger picture but most people in the world! It got me wondering why we humans have such a troubled existence and I quickly arrived at an answer: we do not know what we are. When I think about the cosmos - which I do ever so often with a friend of mine - I realize how special I am. How special we really are. That we've come to be in this unquantifiable "mess" is no easy feat. We are even more mysterious and special than the universe itself. I dream of a time when humanity will discard its differences and see itself as one ever driving force whose purpose is to look at the big picture and decipher its meaning or even give it meaning if it so happens that it is of a random cause.
