hi all the LIGO gravity wave announcement is really exciting and WAY COOL for a lot of reasons. its the 1-century anniversary of einstein making the prediction. “einstein strikes again!” much like universe expansion, he changed his mind over their reality but seemed to have settled on their plausibility.[b2] its another huge victory for Big Science™. the experiment has extreme sensitivity and cost about ~$1B over several decades. it was heavily funded by NSF instead of european agencies, although there are other detectors set to go online soon. its a tour de force of experimental science.
there is a big CS angle here, playing a supporting role unf with little fanfare. articles state at least 24M cpu hours were involved in simulations; the figure is probably much higher. (few seem to be keeping track.) it was largely processed by Atlas, operated by Albert Einstein Institute.
this is all fabulous, but could some day a CS-centric initiative (eg into the deep aspects of say complexity theory or automated theorem proving) be launched with similar scale and epochal results? am feeling someday CS may play the starring role.
so, two black holes merging in one of the most energetic cosmic events ever traced, apart from the big bang. actually its quite reminiscent of the big bang and one sort of wonders, maybe, like out of the disney movie of the same name, the end game for black holes is for all of them to eventually merge and swallow the entire universe… and then but of course maybe that leads to a new big bang?
scientists are expecting on the order of tens of similar events per year! so this is an entirely new branch of observational physics and science born this week. scientists and physicists around the world are nearly giddy (as much as is possible for meticulous professionals!).
think, gravity waves and higgs discovery only a few years apart. it seems to be a golden age for physics. it reminds me of that famous shakespeare quote:
There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy.
gravity waves are basically a dynamic ripple in space-time. physicists have been somewhat conditioned to think of spacetime as stretchable but mostly somewhat monolithic and static. now we have a new very dynamic picture. it also reminds one of the long attempts to unify general relativity and quantum mechanics that go back to einsteins age.
