"On Thursday it's predicted that LIGO scientists will announce the first clear evidence of gravitational waves, rumoured to have come from the merging of two huge black holes. And if the number of press conferences are anything to go by, we're in for something exciting, with simultaneous announcements scheduled in Washington DC, Livingston, London, and Paris, as well as an online broadcast."
India is moving forward with building their own version of LIGO for future collaboration. Now would be the perfect time to seek funding for this kind of stuff.
My in-laws took my wife and 4 year old son there, despite my protests. She said it was horrible. They literally have a set in the front when you walk in that has wax people standing with the dinosaurs in the wild. It's like the anti-science Christian theme park.

I'm genuinely curious as i haven't heard of any such thing in Europe.
I think this may even be a one of a kind thing in the US.
Now, if we're just talking the mindset of anti-science Christian positions (and not fucking theme parks)- that is certainly widespread in areas of the US, and likely also unique to most of the world. Except maybe fundamental muslims or something, I guess...

It really is interesting how that form of Christianity exists in the US. You'd expect Catholics in Europe in the proximity of the Vatican to be similar but it's not really the case. The extreme her are the Mary apparitions and miracles.
Would they just congeal into a super massive hole?
I thought it would be a bit more dramatic. I'm talking from a place of total ignorance but I always thought our universe is like a big raindrop or some sort of liquid and black hole are just points where something outside has broken the skin /surface tension and everything leaks out there.
Be cool if we knew. Doubt there's many bookshelves in them though.

Basically, as your follow-up post guesses, they just become a larger black hole--but, as one would imagine, these are pretty significant events, and colliding black holes were one of the important parts of that discover of gravitational waves a few months back. This page describes the event in a brief outline, although it's outdated (saying that waves haven't been observed): http://hubblesite.org/explore_astronomy ... d3_q6.html

Cool thanks fella.
I'll want to watch interstellar again now
Here's another sort-of-explanation (more up-to-date, but still made before GWs were discovered):
20 seconds in and already I have a question. About the rubber sheet and ball idea. How can something all around us be brought down to thinking about it as a flat sheet. It can't be flat if its surrounding us completely 360 and in all degrees

I think that's definitely an inherent limit of the analogy. Best to limit thinking about "the sheet" when thinking about solar systems (and to a lesser extent, galaxies), since they're all on basically the same plane and orbiting the same center of mass.
If you really want to get freaky-deaky, you can do some research into how every atom in the universe is exerting a gravitational pull on every other atom. That's right: there's an atom in your left pinky toe that's pulling on an atom on the other side of the Andromeda galaxy--the affect is way, way too small for any instrument we have to measure, but those sorts of predictions match up with everything else about gravity that's been observed. Now the sheet doesn't seem like so big a deal, does it?
