For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.
Brian GreeneFor me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.
Brian GreeneThat is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined in that arena, but then it falls apart into a something and an anti-something. And that something is then what we call the universe. But can we really understand that or put rigorous mathematics or testable experiments against that? Not yet. So one of the big holy grail of physics is to understand why there is something rather than nothing.
Brian GreeneWhen you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline's mass into energy, in accord with Einstein's formula.
Brian GreeneEvidence in support of general relativity came quickly. Astronomers had long known that Mercuryโs orbital motion around the sun deviated slightly from what Newtonโs mathematics predicted. In 1915, Einstein used his new equations to recalculate Mercuryโs trajectory and was able to explain the discrepancy, a realization he later described to his colleague Adrian Fokker as so thrilling that for some hours it gave him heart palpitations.
