Why you can buy a Bobble-head Einstein

This week's Sabine Hossenfelder video is on Special Relativity: This Is Why You Misunderstand It.
The most important part of Einstein's theories is that they combine space and time into one common entity, space-time. This idea didn't come from Einstein but from Minkowski, but Einstein was the one to understand what itmeans. Which is why today you cany buy a bobble-head Einstein but not a bobble-head Minkowski. Sorry Minkowski.
No, the idea came from Poincare's 1905 paper, and further developed by Minkowski in 1907. Einstein missed it in his papers, and even admitted:
Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore.
Almost everything she says was from Poincare and Minkowski, and not even understood by Einstein until around 1915. She adopts a modern geometrical interpretation that Einstein rejected most of his life.

  1. You combine space and time... and then notice nothing moves.... except the person who actually is looking at it. Spacetime can only function (at best poorly) when you do a sleight of hand with time and space, you basically outsource your time to the idiot looking at your static space time graph. What a ridiculous con job of physics to place so much emphasis on a model of reality that doesn't even allow for anything to move much less start moving without the observer pushing it along like a child's toy car. So much for reality.

    I'm curious how Einstein, the man who thought the moon was there even when you weren't looking at it, could conceive of a model of space and time that didn't function without an observer's eyeball tracking through the damn time frames to make it go like a kid's cartoon... a movement which is not even possible within said space time.

    If folks want to idolize such nonsense, no wonder they aren't able to figure things out.
