In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to think about space is to just kind of imagine a big piece of rubber that you can pull and twist and bend.
More philosophically-minded critics regarded Einstein's argument for relativity as little more than a logical bait-and-switch ploy: "[T]he supposition of most expounders of the Special Theory, that Einstein has proved the relativity of simultaneity in general - or that his 'simultaneity' is something more than a logical artefact - must manifestly be given up.
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.
The best everyday example of relativity, the finest symptom of human intelligence, is humor. (...) Design without humor is not human. The word 'beautiful' does not mean anything. Only coherence counts. An object, design or not, is primarily an object that meets the parameters of human intelligence, which reconciles opposites. The lack of humor is the definition of vulgarity.
[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did
Whatever God felt about anything, He still feels. Whatever He thought about anyone, He still thinks. Whatever He approved, He still approves. Whatever He condemned, He still condemns. Today we have what they call the relativity of morals. But remember this God never changes. Holiness and righteousness are conformity to the will of God. And the will of God never changes for moral creatures.
Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.
Brahman is beyond mind and speech, beyond concentration and meditation, beyond the knower, the known and knowledge, beyond even the conception of the real and unreal. In short, It is beyond all relativity.
