that particular galaxy was "only" 55 million light-years away or so...so when the light originated, we were still running around with the dinosaurs here on our flat earthIf this is several billion years old, I wonder how creationists will explain it. Maybe since the earth is flat, it will not get sucked in... the earth is aerodynamic ;)
The things I can think of "emitting" from black holes are Hawking radiation, the jet streams and (possibly) gravitational waves (the same way a big boat would cause waves by moving through water, so not really emitting it, but hey.)My bad, I was speaking more towards the light scientist have caught emitting from the center of a black hole. But yes, the light we see surrounding a black hole remains visible because of the bend in space time. In fact, it's the only explanation for WHY we would see it in the first place. I think I was typing before thinking ... lol
But yeah ... black holes are pretty cool. It was an awesome song in the 90s too ...
Interesting that this auspicious event(horizon) has occurred so close to the 15th of April, which is tax day in the U.S., and every year a large percentage of my earnings disappear into a black hole also known as the internal revenue serviceNow lets hear some off the wall test theories as to what a black hole is.
That's an interesting article, thanks!Here's an article on the subject regarding light emission. Here
For two weeks, the astronomers were able to observe flashes of light being released by the newly active V404 Cygni, which is one of the closest known black holes to Earth. It was woken up when the gravitational pull of its partner star pulled the two in too close, causing the black hole to strip away the surface matter of the star, before the whole thing fell in to release an incredible burst of radiation.
Just ask away and I'll answer to the best of my ability.I want Darth Matter to explain all the things to us.
I would humbly accept a specialized Forum title as payment for that role.
I have no idea what you just said but.. 1) I am thoroughly turned on, and 2) I am forced to believe what you said.The things I can think of "emitting" from black holes are Hawking radiation, the jet streams and (possibly) gravitational waves (the same way a big boat would cause waves by moving through water, so not really emitting it, but hey.)
Now, I'm a little rusty on the details. But Hawking radiation should be a way to make sure black holes don't violate too much of the known physical laws, and quantum physics in particular. One of these laws is that information on a subatomic scale can't be destroyed. So there should be some form of evaporation/information leaking out of the hole, although this is not in the form of light/photons. This isn't experimentally proven, but this model does give a lower limit to how small black holes can be created, which agrees with current observation.
With the jets, the story is a little different, as the jets are made up of energy not getting sucked into the black holes point of no return before being shot out at close to light speeds. Mass that gathers around the hole will fall closer and closer to the hole, as their potential energy is converted into kinetic energy. Due to how energy and rotations work (too long mathematical headache to do here), the black hole has to make the material loose energy to make it actually fall in and not just spin around faster and faster. This energy loss is... taken care of by the jets. Material/energy is shoved away along the poles of the black hole without passing the event horizon/point of no return. These have been detected before. Might even exist pictures of them. Or at least of jets forming the same way from other kinds of astronomical objects.
If you can find where you heard about scientists detecting photons from beyond the event horizon (at least, that's what I guessed was going on) I would LOVE to read more about it. Seriously, finding experiments going against common physics is the most fun.
