NASA's black-hole hunting telescope has captured a cosmic battle between dark and light.
NuSTAR, formally known as the Nuclear Spectroscopic Telescope Array, has observed a supermassive black hole's gravity tugging on X-ray light that's being emitted near that black hole.
That light is getting stretched and blurred, and researchers are getting to see it all in unprecedented detail, said NASA in a news release issued today.
Scientists can now see the corona "lighting up material around the black hole," which allows them to study "the most extreme light-bending effects" of Albert Einstein's theory of general relativity, said NuSTAR's principal investigator, Fiona Harrison, in the news release. She is with the California Institute of Technology.
As if NuSTAR's observations and Einstein's theories aren't mind-boggling enough, NASA says the black hole Markarian 335 "spins so rapidly that space and time are dragged around with it."

Apparently the black holes spin so rapidly that space and time are dragged around it! What that means precisely and the consequences are beyond my meager mind.
"Well, in our country," said Alice, still panting a little, "you'd generally get to somewhere else—if you run very fast for a long time, as we've been doing."
"A slow sort of country!" said the Queen. "Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!"

Black hole bends light, space, time -- and NASA's NuSTAR can see it all unfold
This is pretty exciting and mind-boggling stuff.
It gets better. Apparently the black holes spin so rapidly that space and time are dragged around it! What that means precisely and the consequences are beyond my meager mind.

The universe is full of weird and wonderful things and we are not even beginning to scratch the surface on what we know about it. Just imagine what we could learn if our efforts were fully focused on knowledge and benefiting the human condition, rather than all the crap that goes on in the world for the benefit of a few.

Dragging time around, means that things go slower. The faster your velocity, the slower the rest of the universe seems to be moving. This allows for unstable sub-atomic particles traveling close to the speed of light to live longer than they otherwise would if they were stationary. In sci-fi terminology it's like a stasis-pod to keep anything from aging. So if you could get a restaurant/spaceship into an orbit around a black hole, you could in theory live long enough to own a restaurant at the end of the universe.

The good side to all this is that mass will be in a sleeping state. Where it can recover any lost energy well it existed as a rock or light, gas, or what ever.
