String theory posits that all particles are vibrations on tiny strings, and physics is the harmonies you can write on these strings.

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.

Twistor theory, which I started in 1963, has had many developments and has spread interest in different areas of physics.

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

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 many worlds explanation is currently the best way to explain quantum mechanics, but its epistemic status can change with new experiments.

I believe it's possible to unify general relativity and quantum mechanics, as history shows that physics has often moved towards unification, like how Maxwell unified electricity and magnetism.

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

The theories that explain the universe often involve the same mathematical objects that solve mathematical problems, indicating a deep connection between the two fields.
