John Archer Bull Wheeler, a great physicist of the 20th century.
I had him as a professor in graduate school.
In fact, I met my wife in relativity class that he was teaching.
I was sitting in the back row.
She was in the front row.
And then you guys made relatives.
What I can't quite wrap my head around is, if gravity is just the curvature of space and time, maybe it's not a force.
Because forces have these carrier particles.
And if you're just falling along a curvature of space and time, what does it even mean to think of that as a force?
So maybe it sits outside of the quantum paradigms that would require that there be a graviton.
Oh, that's a t-shirt if there ever was one.
