26 New Black Hole Candidates Found In Andromeda
William Robinson writes "Astronomers have discovered 26 new likely black holes in the neighboring Andromeda galaxy — the largest haul of black hole candidates ever found in a galaxy apart from our own. The central region of the Andromeda galaxy is chock-full of black holes, according to extensive observations with NASA's Chandra X-ray Observatory."
These 26 black hole candidates add to nine previously known for a grand total of 35.
to all the atoms and radiation that gets sucked into a blackhole? does it just disappear into nothingness?
Interviewer: What would you say your biggest weakness is?
Black Hole: Dumb fucking question! [spaghettifies interviewer]
Cool! maybe we can finally measure the speed of dark!
...In my frame of reference, at least.
And it's RIGHT BEHIND YOU!
.. there's a reality show/politics joke in there, somewhere; I just know it...
An enigma, wrapped in a riddle, shrouded in bacon and cheese
So you're saying that in a few hundred thousand years, radiation levels in the Andromeda galaxy will have risen too high for it to continue supporting life? That means those aliens who took over the Enterprise and tried to leave our galaxy with it will be here soon! Panic! Run!
The miky way, our galaxy, is scheduled to collide with the andromeda galaxy in 4 billion years. What if we hit a black hole? This universe is getting more and more dangerous all the time.
Talk about a wild midseason replacement!
Each week, we eliminate some of them, until the live broadcast, at which point America texts in their votes, and they pick one to be black hole?
It's what can we do with them. We know they exist, how about scientists find some great functional use for Black Holes - that way, when we can eventually get near one, we can use them for something. Obviously theory is fine, but.. GET CRACKIN'! Great, there are a dozen more, who cares! Find something to do with them!
I thought this was a story on the 2016 presidential race.
Table-ized A.I.
....there are quite a few "black hole" candidates in Washington.

There are 2 groups of people you can make fun of on the Internet without fear of attack. The illiterate, and the Amish.
The idea of a white hole was originally proposed by Igor Novikov, a Russian astrophysicist (with degrees in physics and astrophysics...). The idea is a valid solution to the Einstein field equations, and can be derived as a natural extension of the Schwarzschild metric. That is not to say they actually exist, only that they would not violate general relativity.
Such work is a perfectly valid approach to physics. You take a a tested theory and see where the mathematics goes, to see if it predicts new things that could be observed. Ideally you find something that must exist because that provides a strong test of the theory, but sometimes you find it just says something could exist, which is much weaker, and still might not allow for a process for such a thing to come into existence even if it allows for the existence. But you keep an eye out, and a few times that has resulted in new discoveries, but must remember that is is still possible for the theory to be correct and such an object not to be findable anywhere.
The problem isn't mathematicians taking over physics, it is when blurring or forgetting the line between the idea of something must exist according to a theory and it being a possibility, with or without reason to think such a thing could have formed. More often than not, this is a vice of pop-sci, which is often quite interested in the more exotic topics that fall into the latter category, although physicists will make that mistake too.
The big thing that differs physics from math is that in physics you need to know the history of the science, not just the formula.
There is really only three reasons to know the history: for pedology as some of the older models are simpler and make good introductions, as a source of ideas that may inspire new ideas or help explain why new ideas don't work, or for curiosity. This is no different for math than physics. The big difference between math and physics is that the latter requires familiarity with both the math and observation..That doesn't forbid speculation, just means you need to keep things in perspective and know that something is speculation.
A very simple model (but incorrect) for black holes is as a gravitational singularity.
And now you seem to be getting into the territory of either not explaining yourself well, or suggesting that you may be one of the kinds of people you speak out against, having an opinion on something they are not familiar enough with.
(For the record, while I had degrees in both physics and math, I ended up becoming an experimentalist...)

As Kryten explains, a white hole is a very rare spacial phenomenon - for each action there is an equal and opposite reaction, and whereas black holes suck matter from the universe, white holes spew time back into it.
