Quote by Walter Isaacson

“This concept of the cosmos that Einstein derived from his general theory of relativity was elegant and magical. But there seemed to be one…

“His head-snapping insight was that gravity could be defined as the curvature of spacetime, and thus it could be represented by a metric tensor.”

— Walter Isaacson

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the…

— Richard P. Feynman

The whole idea of gravity curling up space, that is the epitome of what is going on in a black hole. I would've loved…

— Rainer Weiss

“Gravitation is not curvature of space-time, it is the stress of space itself, caused due to formation of matter from space.”

— Devinder Kumar Dhiman

“Now, at the outset of the twenty-first century, we stand on the verge of a new revolution. The search for a deeper theory than…

“Instead, this time he made what he called a “slight modification” to his theory. To keep the matter in the universe from imploding, Einstein…

— Walter Isaacson

It is ironic that Einsteins most creative work, the general theory of relativity, should boil down to conceptualizing space as a medium when his…

I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.

— Antony Garrett Lisi

Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the…

“Impressed by the success of high-level mathematics in the formulation of the general theory of relativity in 1915, we find that Einstein's life-long quest…

— John D. Barrow

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