Single Idea 19482

[filed under theme 7. Existence / A. Nature of Existence / 5. Reason for Existence ]

Full Idea

Our best theories of physics imply we shouldn't be here. The big bang ought to have produced equal amounts of matter and antimatter particles, which would have almost immediately annihilated each other, leaving nothing but light.

Gist of Idea

Current physics says matter and antimatter should have reduced to light at the big bang

A Reaction

This is not, of course, a rejection of physics, but a puzzle about the current standard model of physics.

19954 It is impossible for find a model of actuality among the innumerable models in string theory [New Sci.]
19953 In string theory space-time has a grainy indivisible substructure [New Sci.]
19952 Black holes have entropy, but general relativity says they are unstructured, and lack entropy [New Sci.]
