A century of General Relativity, proposed by Einstein

November, 2015, is the 100th anniversary of Albert Einstein's presentation of his General Theory of Relativity. This theory gave impetus to other ideas, including an expanding universe, black holes. As the Wikipedia says, this theory is still the best current description of how gravity works, 100 years after its proposal. (However, most of us, including some scientists, don't talk about gravity that way. We speak of it as if Isaac Newton had explained it. He was almost right.)

New Scientist has a timeline of the most important events related to this theory, since that time. We are not yet certain about what is going on with dark matter, and we have no "theory of everything" relating General Relativity with sub-atomic structure, but some amazing discoveries have occurred, in the century following 2015. The Atlantic also celebrates, pointing out that GPS satellites wouldn't work correctly if they weren't corrected for the effects of General Relativity.

See this post on the Big Bang, which is by no means necessarily a disproof of God's creativity.

Thanks for reading.
