43. Discussions With Dongyi Liao On Scientific Philosophy to entertain alien / god worlds that have THAT much common ground with us (if they start with L or HL or general_relativity, that s even better), http://mt.seas.upenn.edu/Archive/Papers/99/discussion_dongyi1.html

We use to think that "logic" is "self-evidently" correct, for instance the rule of "deduction by contradiction": Proposition 3 (~p -> ~q) -> (q -> p) People would nod when they hear me say "because... thus... so... leads to... contradict with... suppose... must..." etc. However, do we "leap" somewhere above? Which of them are the real "atoms" of logic? Suppose two people write down two proofs of a theorem, almost any human can immediately see they are "equivalent" or not. But how can a machine do that? In other words, we should port our usual free-style of proof on paper, to a maximally restricted "action set", at least once for a lifetime. The formalism which I'll describe in the next paragraph is Symbolic Logic . The reason for following this procedure is that only then can we fully drive "human intuitions" or "common sense" out of our proofs - it might be wrong, just like the "axiom" of 3D Euclidean space. Only through the uncomfortable procedure of symbolic logic can we clearly chart out the hierarchical structure of the Knowledge Tree in which all conscious entities reside; Russell proposed that the human

Modern : General Relativity (Albert Einstein) "When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter." General Relativity: Metaphysics Metaphysical Problems of Albert Einstein's General Relativity Einstein (from Faraday, Maxwell, Lorentz) represented matter as a continuous spherical electromagnetic force field in spacetime. Thus Einstein argues that there is no 'particle' and matter is spherically spatially extended, effectively uniting Space, Time, Matter and Gravity as One thing, spherical fields. i) Einstein's Relativity is a Theory of a posteriori Effects not a priori Causes, and is founded on Many things (Matter) rather than One thing (Space). However, Metaphysics is founded on the Principle that Reality must be described from One thing that causes and connects the many things (not from our empirical senses of the many things / matter). Unfortunately, Einstein did not know how matter existed in Space and his electromagnetic field theory of matter is Inductive (empirical / a posteriori) and describes effects (of relative motion). The theory of relativity leads to the same law of motion without requiring any special hypothesis whatsoever as to the structure and behavior of the electron. (Einstein, 1954)

Click here to download a PRINTABLE pdf version of this page. In 1916 Albert Einstein put forward his theory of gravity called General Relativity . In this theory Einstein assumes that the effects of gravity can be described in terms of the curvature of space and time together. This hybrid 4-D space, upon which Einstein formulated his theory, is called spacetime . There are three dimensions of space in the four-dimensional spacetime combined with one dimension of time. In General Relativity Einstein links the curvature of spacetime with the way matter and energy are distributed in the universe. One can summarize the coupled arrangement between matter and spacetime curvature in Einstein's gravity theory by the following statements: Mass (the source of the gravitational field) tells spacetime how to curve. Spacetime tells matter (any massive body besides the source mass) how to move. Before Einstein's radical proposal about spacetime, space was thought of as an unchanging stage upon which all the motions and interactions of matter were played out. Space was like a tabletop upon which transactions occurred independently of the structure and layout of the table. Einstein's ideas however implied that space was highly changeable. It was like a flexible material that accommodated every massive object by curving appropriately in the local vicinity of the object, much like a stretched sheet of elastic material would accommodate itself to a heavy ball placed on its center area.

Main October 03, 2007 The Mystery Lurking at the Center of the Milky Way It is always a joy to find that there are no absolutes in science. Rules that have long since been taken as fact get thrown out the window with one unexpected discovery. One needs look no further than the scientific “facts” that the earth was the center of the universe, or that it was flat, to find out what happens. The latest scientific fact fearing for its future, is Einstein’s own Theory of General Relativity. The competition lies within the swirling mass of a black hole, a naked singularity. Each black hole contains a singularity, according to general relativity. When matter collapses in on itself, as a sun will do leading to the inevitable creation of a black hole, it forms a point or ring of infinite density.
