#10 Black holes are truly fascinating and complex. Firstly, though, light can and does "escape," it just gets stretched to a wavelength that we cannot see.
The "event horizon" is so named because from the perspective of everything outside the black hole, all events stop. Completely. If we could observe an object reach the event horizon, it would freeze in time and remain that way for eternity, never changing in any way whatsoever no matter how many trillions of years we observed it. Forever. This is why we'll never be able to see inside of one. "Information" does escape, however, in the form of Hawking Radiation, and even all black holes, like stars and planets, will eventually fade away from existence due to entropy.
For the object entering the black hole, events would occur normally. The object would get stretched out, forever falling into the singularity- a point of infinite density in which all quantum mechanics break down. It's a place in which any direction you turn will always face the center.
The stretching, or "spaghettification" happens because the gravitational force overpowers the bond between molecules. As it falls, gravity becomes even more powerful than the strong and weak nuclear forces and rips apart the atoms themselves, breaking them down into the most elementary particles of matter- strings.
The details of what we know about quantum mechanics take us almost all the way down, but since we can't directly observe what ultimately happens, it's still a mystery. Unfortunately- barring some massive, physics-altering technological breakthrough- the answer will continue to elude us indefinitely.
TL,DR: Black holes are really, really neat.

#26 The average human blood cell is comprised of many trillions of atoms. If you had a chunk of matter made of 10 billion atoms, you wouldn't be able to see it at all.

#19 they had me until mathematics and philosophy... mathematics is applied reality. Because no amount of opinions change what 2+2 is only what we call it. Math is understood by all species.
