Mapping the road to quantum gravity
http://phys.org/news/2014-04-road-quantum-gravity.html
"Lee lays out the problem: "Physics has one theory to describe how planets orbit the sun and another to describe how electrons 'orbit' an atomic nucleus. Both theories – gravity as described by Einstein's general relativity and quantum field theory – are great triumphs. Both are well-tested and powerful. The trouble is, we can't use both at once."
Relativity says that spacetime is smooth, and only big things can warp it, in ways that are exactly known. Quantum theory says that the smallest parts of the universe are constantly fluctuating and dramatically uncertain. How can something be both smooth and fluctuating, both exact and uncertain? How, in other words, can we make a quantum theory of gravity?
Physicists simply don't know. Researchers in both string theory and loop quantum gravity have made progress, but a fully functional unified theory has remained out of reach for more than 80 years."

"Physicists simply don't know."
Juuri näin ja he eivät yksinkertaista vain tiedä / ymmärrä sitä ettei vetävää voimaa / kaareutuvaa avaruutta edes ole olemassa!
Kaareutuva avaruus / vetävä voima on ihmisen hatustaan tempaisema käsite / jumala jota ei ole olemassa!
