Is General Relativity a Dead End?
Don't get me wrong, General Relativity is brilliant. It's probably the greatest insight ever produced by a single individual. And it's built from an amazing observation..
That at a given point in space acceleration is equivalent to a gravitational field. That's clever to say the least.
But we can regard an acceleration as a stress on space-time. So what happens in the Quantum limit when the acceleration is truly huge? Does it fracture space-time into discrete units or some underlying fundamental constituents?
If so that's where GR breaks down. And GR was a nice macroscopic average.
And don't forget, GR assumes space-time is a continuum. That's a classical concept which simply cannot be true at very small distances.
Bottom line: GR has to break down at some point. It's great at making predictions at the classical level. But it cannot move to the future. It's a dead end. An incredibly clever dead end. But a dead end none the less.
