Last year, I fell down a rabbit hole of reading about bumblebees (they are awesome btw, they have thumbsized ones in Brazil), and a line stuck with me forever - " bumblebee queens rule the hive with a combination of pheromones and violence'. I thought they were cute before, now I think they are cute and badass.

Oh, that's what a horse fly is ? I've always called them blow flies, and had no idea what a horse fly was. TIL.

So black holes with accretion disks are already cool – no matter the orientation, the disk never obscures your view of the shadow of the event horizon. In fact, you always see the entire shadow, because gravity bends light from just outside the back side and sends it our way. Similar bending occurs on the light coming from the back of the accretion disk, so we see a really cool 360 view of black holes! https://www.youtube.com/watch?v=zUyH3XhpLTo Well Nasa just worked out what it would look like if all that gravitational lensing occurred for binary supermassive black holes https://www.youtube.com/watch?v=rQcKIN9vj3U

Black holes "should" last infinitely, cause they just eat stuff forever (excepting Hawking radiation). Just stumbled across white holes though, which "should" last for an infinite short time, puking out all their (and their source black hole's mass with the same energy as said black holes suck mass in. Possibly the source of our own Big Bang. How are white holes created from black holes? Yes (best laymen answer I've seen so far). Apparently we're looking for a white hole right now, even though they may take forever to form, and may last a forever a small time (I like more and more that "infinity" just means we haven't figured out what ever it is is just yet). https://m.youtube.com/watch?v=wWzEUDk-9m0

Otteration posted:Black holes "should" last infinitely, cause they just eat stuff forever (excepting Hawking radiation). This post and that video are not very good characterizations of what a "white hole" is. Long story short, a white hole is a mathematical quirk that pops out of the mathematics of the most basic and naïve formulation of a black hole, one that postulates a non-rotating, uncharged black hole in an otherwise empty universe for eternity. They're an extension of the black hole and they occur basically in another universe as a consequence of the existence of the universe with the black hole, and they're the opposite of a black hole - instead of all possible paths ending at the singularity, all possible paths start at the singularity. In other words, instead of light (or anything else) being unable to escape, it is unable to get in. You can (mathematically) construct a series of universes where infinitely long paths go from a white hole, through infinity to another universe, and into a black hole, and out a white hole in yet another universe, and so on. This is all obviously the sort of nonsense you get when you make a mathematical model that is too simple. I'm not sure where you got the "take forever to form" and "last forever a small time", since by definition they don't form - they always exist and last forever in their extremely simple mathematical model of a universe. Once you remove the perfect symmetry of the empty universe, or the symmetry of the black hole existing for all time, there is no longer any reason to think there is a white hole counterpart to a normal black hole (of the sort you might get from a collapsing star, for example, or the supermassive ones at the centers of galaxies). However, there have been various ideas of how to re-jigger the white hole idea to try and explain the origins of the Big Bang. Interesting ideas, to be sure, but ultimately doomed to fail for now, because we do not have a complete theory of how the universe works on very, very, very, very, very small scales. There is little reason to think that such a thing as a "black hole singularity" (as in, an infinitely dense point of finite mass) is real, and not a consequence of a limited theory, and therefore, no good reason to suspect that matter might be vanishing into another universe to pop out of a white hole. Not that "the big bang is a white hole, and black holes create universes" is a bad theory, just one whose time is yet to come, and one which is neither mainstream nor well-supported. I'm not sure how they mathematically reconcile the instantaneous nature of the "Big Bang white hole" with the non-instantaneous nature black holes, but it's been a long time since grad school and my general relativity is rusty, so I'm not sure if I could tell you whether it's properly explained or just a load of horseshit.

The PBS Space Time series on Youtube are excellent continuations on these for anyone who found this interesting. The guy who does them is an actual astrophysicist and the videos are interesting and engaging without stooping down to the "SOOOO EPIX" that too many contemporaries fall into. Space is interesting enough! It doesn't need zazzing up!

Cool, thanks for the correction.

White holes, much like string theory, warp drives, wormholes, and other things we don't fully understand, are a thing that much pop sci communicates wrongly as a result of the popularizer's untempered enthusiasm for bizarre speculative ideas. It's not so much that there's disagreement on the facts, it's that there's disagreement on how to communicate them on a spectrum from exciting to realistic. So I'm here to give you the realist interpretation of the facts at hand.

So I'm here to give you the realist interpretation of the facts at hand. If we don't fully understand a thing, how is it possible to communicate it wrongly? Lots of pop sci are quoting actual theoretical physicists in an attempt to describe white holes to the rest of us, despite those physicist's wide ranging opinions, and lots of bizarre speculative ideas come from those same physicists. No one is saying saying that they are big foot. If you have a unified theory to describe them to the general public in understandable language, go for it please. Until then, they're going to be the equivalent of "Spooky action at a distance." https://www.pbs.org/wgbh/nova/article/are-white-holes-real/ The Bad rear end tangent is that we monkeys will figure it out eventually, or at least die trying to (or maybe die hitting each other with bones because of the thing that suddenly appeared).
