Strangely, massive black holes are much safer to visit than small ones. The dangerous gravitational tidal forces that can rip you apart occur inside the event horizon of super massive black holes, and it's relatively safe to approach and establish an orbit at a reasonable distance. You can do some "time travel" into future, too, by hanging around in the high gravity zone for a while.
Second? I assume Australia, but what about Komodo Island?
It’s a real-life version of one of the most feared monsters in horror fiction… only smaller. A lot smaller. On Wednesday, an international team of researchers unveiled the fossilized remains of an ancient relative of the sea cucumber. It had 45 tentacles and lurked at the bottom of the seas some 430 million years ago.
A new species of crab that scientists say is the "strangest crab that has ever lived" has been discovered in Colombia and the United States.
The prehistoric crab dates back to 95 million years ago and scientists say it defies all the normal crab features. The new species, named Callichimaera perplexa, has bent claws, big eyes with no sockets, an exposed tail and leg-like mouthparts.
