Sometimes it takes a second look or even more at an astronomical object to understand whats going on. This is what happened after astronomers obtained this image of NGC 5548 using the Hubble Space Telescope in 2013. While crunching the data, they saw some gas moving around the galaxy in a way that they did not understand.
From the supermassive black hole embedded in the galaxys heart, the researchers detected gas moving outward quite quickly blocking about 90% of the X-rays being emitted from the black hole, a common feature of objects of this type. So, astronomers marshalled a bunch of telescopes to figure out the answer.
Heres what they knew before: black holes force matter into a spiral that surround the object, creating a flat plane of material known as an accretion disc. Heating in this disc sends out the aforementioned X-rays as well as some ultraviolet radiation. But NGC 5548 is doing something different.

How does time react in a black hole? If not even light can escape, then it must warp time and space, so does that mean like a minute of our time would equal an infinite amount of time in a black hole?
Man knows one tenth of one percent of nothing, and we are not getting smarter, never mind common sense. In the future this will be irrelevant.
Oh I thought this was talking about Obama’s ass.
I went to a planetarium show with my family not too long ago. The “astronomer” opined at the beginning that the laws of physics break down as you approach and cross the event horizon. He then went on to tell us that time freezes at the event horizon so you could actually watch the universe age and pass away there. Uh, dude... you already said the laws of physics break down... put away the equation and picture matter and energy screaming its way to a superdense core, not hanging out watching the universe go by.
I didn't read the article, but is this another one of those cheap shots at America's film maker, Michael Moore?
You are pretty close to the truth. A black hole, I believe, is that region of space where time obtains a value of zero. In other words time stops. Assuming you could get inside the event horizon without getting ripped apart (you can't), you would never know it because you would never leave that instant in time.
“Assuming you could get inside the event horizon without getting ripped apart (you can’t), “
Some of the butter on the lobster might have gone rancid?
NGC 5548 is 245 million light years away.
Time would appear to move normal to the space traveler, but slowed to the observer.
If the traveler were somehow able to break free of the event horizon and return to Earth, he would find that the Earth and likely the entire solar system are gone - vaporized in a super nova millions of years prior to his return...
darn it...you beat me to it!
The Flotus has flatus?
Sorry. Don't buy it. By the time you reach the event horizon, you are screaming like a bat out of hell toward a very unpleasant coupling with a singularity. The fact that we believe time stops shows that the equations just don't work here. I know, I know... you must have light in order to have time. Got it... but just because light has been stopped in its tracks doesn't mean you are.
The tidal forces have already pulled you apart thousands of miles from the event horizon.
The fact that we believe time stops shows that the equations just don't work here.
It's not a matter of belief, it's a matter of science. And saying that equations that predict a result therefore "don't work" is manifest, self-contradictory nonsense. The equations predict the presence of singularities, and they predict what happens in the near vicinity, including the event horizon.
I know, I know... you must have light in order to have time.
This statement is more nonsense. You don't need to have light in order to have time.
Got it... but just because light has been stopped in its tracks doesn't mean you are.
All you've "got" is a very confused idea of what General Relativity says happens at the event horizon of a black hole. No light is required, and the field equations do NOT "break down." General Relativity describes gravitational attraction as a geometric phenomenon, and that geometry applies to light, neutrinos, gauge bosons, or any other matter or field in space.
I’d throw a “like” on here if we had it.
