Ladies and gentleman: This is a black hole

Well, this black hole we imaged is in a diggerent galaxy. As far as Sag A*, the black hole at the center of our galaxy, it is gaining mass much,much faster than it is evaporating.

I see. Interesting Sgr A* is getting larger. Will we get a pic of our black hole in the near future?

To be clear,we haveno direct observation of its increasing mass. But we know material is falling into it, and we know how slowly it evaporates.

We're trying to get an image of it right now. But we are being photobombed by a magentar:

It does seem like this is a big feather in the cap of atheist scientists. What could be valuable is the energy being given off by Hawking radiation.
 
Mind bending article on white holes and dark matter:

'White Holes' May Be the Secret Ingredient in Mysterious Dark Matter

"
The local density of dark matter, as suggested by the motion of stars near the sun, is about 1 percent the mass of the sun per cubic parsec, which is about 34.7 cubic light-years. To account for this density with white holes, the scientists calculated that one tiny white hole — much smaller than a proton and about a millionth of a gram, which is equal to about the mass of "half an inch of a human hair," Rovelli said — is needed per 2,400 cubic miles (10,000 cubic kilometers).


These white holes would not emit any radiation, and because they are far smaller than a wavelength of light, they would be invisible. If a proton did happen to impact one of these white holes, the white hole "would simply bounce away," Rovelli said. "They cannot swallow anything." If a black hole were to encounter one of these white holes, the result would be a single larger black hole, he added. "

Cool topic. Could, in theory, propel a starship:

"ARE BLACK HOLE STARSHIPS POSSIBLE?

By Louis Crane and Shawn Westmoreland, Kansas State University

ABSTRACT: We investigate whether it is physically possible to build starships or power plants using the Hawking radiation of an artificial black hole as a power source. The proposal seems to be at the edge of possibility, but quantum gravity effects could change the picture."
