We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Cosmology is enough to make anybody feel mentally ill, disoriented. The very notions of space-time, and of infinity, scramble my brain and make me think about God.
Here's a good piece on the latest: Proof of the Big Bang - A stunning discovery made at a research station in Antarctica indicates that Albert Einstein was right about the nature of the universe:
The colossal forces of inflation caused the fabric of space-time – a concept introduced by Einstein as a way of reconciling gravity, motion and time – to start wobbling, like the surface of a sea subjected to an earthquake. One objection to relativity was that no one had evidence that violent events can make gravity form waves like this. Now they have.
Erp, doesn't Einstein's theory of relativity say we cannot go faster than the speed of light? And don't the scientists in Antarctica say they vindicated Einstein's theory of relativity by discovering evidence that the big bang expanded billions of times faster than the speed of light? Serve mine with an extra olive and extra vodka please. This could take some splainin.
Thanks for the link chuck. I now have a much wiser bookmark list. It always comes down to that pesky space don't it? Performing feats tangible stuff can only dream of. For my part, I'm glad we have unlimited galaxies and universes. First, we now have solid scientific evidence that global warming is a very small problem. Second, those evil, nearly omnipotent galaxy destroying, reality changing, time twisting super villains in the comic books can't possibly destroy everything. A worry I can now retire.
The simple truth is that space time does create a physical barrier denoted in the famous equation. However, there is nothing that says one cannot avoid the speed limit by changing local space time or eliminating it locally allowing for higher speeds. The theory is sound, it's just a question of engineering at this point.
Eventually, the Quantum Gang and the Relativity Gang will have their Unified Field Theory (or the God Equation) which will make the light speed limit an anachronism.
Strictly speaking we were already pretty sure gravity waves existed, since pulsar spin slowdown matched the predictions of general relativity that they would lose energy emitting gravity waves. But we hadn't seen any gravity waves yet. LIGO isn't ready...
