My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
Interpretation
General relativity is accepted because it accurately predicts phenomena observed in experiments.
Brian Greene emphasizes that the widespread acceptance of general relativity is primarily due to its ability to make accurate predictions that align with empirical observations. This illustrates the importance of experimental validation in scientific theories, showing that a theory gains credibility when its predictions can be tested and confirmed in the real world.
In practice
In a lecture about scientific theories, one might use this quote to illustrate the importance of empirical evidence.

All mathematics is is a language that is well tuned, finely honed, to describe patterns; be it patterns in a star, which has five points that are regularly arranged, be it patterns in numbers like 2, 4, 6, 8, 10 that follow very regular progression.
According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.
So: if you buy the notion that reality consists of the things in your freeze-frame mental image right now, and if you agree that your now is no more valid than the now of someone located far away in space who can move freely, then reality encompasses all of the events in spacetime.
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
Science does not aim at establishing immutable truths and eternal dogmas; its aim is to approach the truth by successive approximations, without claiming that at any stage final and complete accuracy has been achieved.
Our task now is to resynthesize biology; put the organism back into its environment; connect it again to its evolutionary past; and let us feel that complex flow that is organism, evolution, and environment united. The time has come for biology to enter the nonlinear world.
Cancer is like the common cold; there are so many different types. In the future we'll still have cancer, but we'll detect it very, very early, so that it won't kill anybody. We'll zap it at the molecular level decades before it grows into a tumor.
Science is a beautiful gift to humanity; we should not distort it.
In the process of natural selection, then, any device that can insert a higher proportion of certain genes into subsequent generations will come to characterize the species.
I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.
