wHat is wisdom???
honestly, who are we to say. Just because the world has convinced us that wisdom is one thing does that mean it couldn't be another? I grew up beleiving that wisdom is a more mature way of seeing the world- but thats the way i grew up. anyone who grew up being toght otherwise. we can't just take a vote that wouldn't provide an accurate answer.
You guys/ girls/ whatever have any input?
- Some are concerned about the proliferation of space debris in Earth's orbit.
Progressive America would be half as big, but twice as populated as its conservative twin.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
