The part with Einstein's eyes moving was pretty crazy.
The explanation of is logical however it still might not be the case withought furthar justification (like proof). This is no better than saying that the sun being destroyed would create a black hole wich would continue to pull the earth and other planets.
The video makes sense, is it really true though?? Also, what is the difference between regular time and space time (not that it really makes a difference, just curious)??
