The first photos of a black hole:

A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow.

Death by Spaghettification (very cool, worth your time to watch)

I liked this video on black holes. This link starts in the middle to make a point.
Light is red shifted into invisibility due to time dilation - rather than light cannot escape.

It's both amazing and mind boggling to think of how far we've come in our ability to see and try to understand the world/universe around us. I love that the people on the Science Channel are very good at describing/explaining it. They're so enthusiastic about it too, and that makes it fun to watch.

Hey Cap! Nice to "see" you and agree with the Science Channel being so enthusiastic about it.

:yeah that: :D


I finally saw a story about the young computer scientist who help bring this image:

29-year-old Katie Bouman 'didn't know anything about black holes'—then she helped capture the first photo of one

daisypusher: watching and working on comprehending. My brain wants to understand this, but it is not fully armed, and there are lots of rusted out pieces.
