Alan -
Are you aware that while gravitation can be mathematically formulated,
- there is absolutely no theoretical basis for how it may operate;
- that the proposed graviton, supposed to mediate gravity (an extension of the Standard Model of particle physics), is a theoretical particle never once yet observed by anyone anywhere;
- that while there is some indirect evidence, there is no direct evidence of gravitational waves as predicted by Einstein a hundred years ago; whereas:
- we understand, at the deepest (i.e. physics, if you really want to) level how evolution works;
- we understand what mediates evolutionary processes;
In the understanding stakes gravitation is still remarkably poor compared to evolution; rather a lot of very good maths and very good ideas and liberal amounts of Pritt Stick, card and glitter than hard knowledge.
