(V): I've never tried visualizing being everywhere at the same time, but I did try to visualize what a space time curviature might look like. It was very disorienting. Couldn't look at it for more than a few seconds at a time. What I fiound interesting about the thought experiment was that I envisioned space contracting, instead of dialating, which at least one theory of gravity says is what actually happens. Try envisioning a vacuum within a vacuum and you will see (and feel) the problem of visualizing it. It felt like a carnival ride. The funny thing about it was that for the most part I got it right, but apparently everything I "saw" was opposite and in reverse order of what gravity (as time dialation) is supposed to be. Space is already a vacuum, so the only way you can acheive a vacuum within a vacuum is by jiggering time so that volumes and distances can change while still remaining to be the same volumes and distances. What I mean is, instead of using a yardstick to measure another yardstick, you can use time to measure a yardstick, If time speeds up the yardstick becomes shorter, slow time down it becomes longer, but in each scenario it still remains the same 36 inches. I watch a few videos of the 12 year old math juggernault, and his grasp of mathematical principles is impressive. I'm not much good at math, so now I know how my kids felt when I tried explaining their homework to them. That's how I felt watching Jacob Barnett explaining calculus and singularities and his thoughts on light speed etc. I was amused and intimidated, but overall I came away with a big smile on my face. I joked about how I hope he doesn't use crayons on the family room wall. He doesn't. He uses an erasable marker to scribble on windows. Close enough. :op
