Do you know ?? Ashoke Sen, the renowned String Theorist of India who produced Sen Conjecture & S-Duality is a student of Amal Raychaudhuri !! Raychaudhuri produced the Raychaudhuri equation. The Raychaudhuri Equation is often taught as a GR tool. But that’s like calling calculus “a physics trick.” Because Raychaudhuri’s equation is deeper than gravity: it’s a geometric statement about congruences and flows.

They've given the Nobel Prize in Physics to a computer scientist and now the Turing Prize to a physicist. The only logical next step is to give the Fields Medal to a barista who can recite the first ten decimals of π while spelling your name wrong on your venti latte cup

Richard Feynman on UFOs 🛸 It is not unscientific to make a guess, although many people who are not in science think it is. Some years ago I had a conversation with a layman about flying saucers — because I am scientific I know all about flying saucers! I said “I don’t think there are flying saucers”. So my antagonist said, “Is it impossible that there are flying saucers? Can you prove that it’s impossible?” “No”, I said, “I can’t prove it’s impossible. It’s just very unlikely”. At that he said, “You are very unscientific. If you can’t prove it impossible then how can you say that it’s unlikely?” But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible. To define what I mean, I might have said to him, "Listen, I mean that from my knowledge of the world that I see around me, I think that it is much more likely that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence than of the unknown rational efforts of extra-terrestrial intelligence." It is just more likely. That is all.

This picture is beautiful but misleading, since it only shows about 0.5% of the cosmic density. The other 99.5% of the universe is invisible.
