The quest for a theory of everything that unifies general relativity and quantum mechanics may not yield a simple equation, as gravity might emerge from quantum phenomena at a macroscopic level.

I offer ambitious frameworks like twistor theory that could potentially unify quantum theory with general relativity.

We haven't unified quantum mechanics and general relativity yet because we don't know what the fundamental objects are, and we need to rethink our notions of space and time.

The strength of geometric algebra lies in its ability to unify various concepts in physics, including quantum mechanics and relativity, potentially offering new insights into quantum gravity.

The connection between quantum mechanics and gravity is a major focus in theoretical physics right now, as there are inconsistencies between the two.

Physics is a victim of its own success; general relativity and quantum mechanics are so effective that they cover 99.9% of observations, making it hard to find deviations to combine them.

The principle of equivalence in general relativity conflicts with the principle of superposition in quantum mechanics, highlighting a fundamental tension between these two theories.

The resolution to the information paradox may involve allowing non-local connections between particles through wormholes while preserving quantum mechanics, suggesting that gravity emerges from a quantum description and isn't fundamental but rather a result of deeper quantum mechanics.

General Relativity is based on two foundational pillars: general covariance, meaning physical laws don't depend on coordinate choices, and the principle of equivalence, which states that gravity is the same as local acceleration.
