Space‑time is dead
Notes
In his General Theory of Relativity, Einstein combined the three dimensions of space with the one dimension of time in what we now know as Einstein’s equations .
Ever since, physicists have thought of space and time as effectively the same thing: components of four-dimensional space-time.
This might be the biggest blunder physicists have ever made.
Stephen Wolfram, on page 22 of his book A project to find the Fundamental Theory of Physics , calls it the “one ‘wrong turn’ in the history of physics in the past century”.
Space-time is dead.
Here’s why... and how physicists got it so wrong for so long.
