“general relativity and quantum mechanics cannot both be right,”

— Brad S. Gregory

General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify…

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

— Pierre Teilhard de Chardin

You know the Einstein waves can be thought of as a distortion of space and time. But the way we see it, we see…

While the finish given to our picture of the world by the theory of relativity has already been absorbed into the general scientific consciousness,…

— Niels Bohr

General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting together…

“The only way and place you can warp space or time is in the human mind; in the physical world it’s impossible because neither…

We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.

— Kip Thorne

A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell us, as…
