you should really read the Wikipedia article on black holes: https://en.wikipedia.org/wiki/Black_hole

some paragraphs you might find relevant to your question:

By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists searching for black holes must generally rely on indirect observations. For example, a black hole’s existence can sometimes be inferred by observing its gravitational influence on its surroundings.

David Finkelstein, in 1958, first published the interpretation of “black hole” as a region of space from which nothing can escape. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. The first black hole known was Cygnus X-1, identified by several researchers independently in 1971.

The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. Any matter that falls toward a black hole can form an external accretion disk heated by friction, forming quasars, some of the brightest objects in the universe. Stars passing too close to a supermassive black hole can be shredded into streamers that shine very brightly before being “swallowed.”[11] If other stars are orbiting a black hole, their orbits can be used to determine the black hole’s mass and location. Such observations can be used to exclude possible alternatives such as neutron stars. In this way, astronomers have identified numerous stellar black hole candidates in binary systems and established that the radio source known as Sagittarius A*, at the core of the Milky Way galaxy, contains a supermassive black hole of about 4.3 million solar masses.

pretty sure that we can’t “watch” a black hole at all, since we need light to see and light cannot escape a black hole

in case you weren’t aware, Reason is a right-wing publication whose foundation is primarily funded by one of the Koch brothers

ContraPoints has a great Tangent video about liminal spaces, FYI

honestly I think it is less about health or safety and more about the disgust people feel - it really might just be irrational and nothing more

ah, maybe I had it backwards, maybe it was a 2 point lead that Trump had over Harris? Anyway, thank you so much for the link, that’s really helpful!

72 million voters voted for Trump, that’s not equivalent with embracing Trump’s hatred. Trump’s base is bigoted and hateful, but that doesn’t mean every voter is. A lot of them seem clueless, by all accounts. I think a lot of them were just voting against the incumbent because they were upset about price gouging and inflation.

I think Harris had a 2 point lead among male voters age 18 - 29. Where is the 2% stat from, I would like to learn more (if it’s convenient to share).
