Alright guys/gals, this one is extremely hypothetical but in a sense does have something to do with us and humans as a species. Granted we don't destroy ourselves or are wiped out by aliens, etc., that is to say that we survive to see the day when all of the energy and matter in the universe starts running out, what will we do? In a more scientific sense: How may entropy be reversed? I realize technologies would be incredibly different than now. It's like comparing rocks to missles. Isaac Asimov wrote about this in his famous short story "The Last Question". If you are interested you can find the full text here, it is a very short read:
- 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.
