Noun
a generalization of special relativity to include gravity (based on the principle of equivalence)
Source: WordNetGeneral relativity is certainly a very beautiful theory, but how does one judge the elegance of physical theories generally? Roger Penrose
An extrapolation of its present rate of growth reveals that in the not too distant future Physical Review will fill bookshelves at a speed exceeding that of light. This is not forbidden by general relativity since no information is being conveyed. David Mermin
The problem with general relativity is that the principles are pretty simple and the computations are always ugly. Leonard Susskind
Quantum Mechanics and General Relativity are both accepted as scientific fact even though they're mutually exclusive. Albert Einstein spent the second half of his life searching for a unifying truth that would reconcile the two. Roy H. Williams
String theory at its finest is, or should be, a new branch of geometry. ...I, myself, believe rather strongly that the proper setting for string theory will prove to be a suitable elaboration of the geometrical ideas upon which Einstein based general relativity. Edward Witten
In Einstein's general relativity the structure of space can change but not its topology. Topology is the property of something that doesn't change when you bend it or stretch it as long as you don't break anything. Edward Witten
