Hi, if you're interested in Einstein could you please measure the speed of light, c? In the future maybe a Ministry of Truth could measure it. 🤔 I bought a portable oscilloscope & photodetectors, but I keep procrastinating. I was thinking of measuring the signal btwn 2 sensors - my laser beam hits one, then bounces back off a mirror & hits the other one. I know audio isn't fast enough to detect a difference (the laser hit both instantly in my audio recordings). I did a course in General Relativity when I was young. I like the math but I think that theory's wrong. Perhaps there's a speed much faster than light. Or maybe Riemannian geometry is useful in some other way, in physics.
The speed of spreading information cannot exceed light speed, but the space itself can. Many galaxies are moving away from us at speeds faster than the speed of light
