Giant black hole is seen gobbling up a star
Source: Los Angeles Times
A star in another galaxy was ripped apart by the black hole's intense gravity 2 billion years ago and recently witnessed by scientists. 'It turned into this really thin piece of spaghetti,' one said.
Back when single-celled organisms ruled Earth, a gigantic black hole lurking quietly at the center of a distant galaxy dismantled and devoured a star.
On Wednesday, astronomers reported that they watched the whole thing unfold over a period of 15 months starting in 2010, the first time such an event had been witnessed in great detail from start to finish.
"The star got so close that it was ripped apart by the gravitational force of the black hole," said Johns Hopkins University astronomer Suvi Gezari, lead author of a paper about the observations that was published online by the journal Nature.

It's fascinating.

Can anybody answer this? Can "God" survive a black hole LOL

(53,410 posts)Did we actually find one and see it in action like this? That's the knowns I believe in. Not the Rummy type unknown knowns.

(53,410 posts)The poster above claimed we've known for quite some time. I notice I didn't get a response so maybe we haven't actually known beyond some theory.
Thanks for the video.
It is now widely accepted that the center of (nearly) every galaxy (not just active ones) contains a supermassive black hole.[104] The close observational correlation between the mass of this hole and the velocity dispersion of the host galaxy's bulge, known as the M-sigma relation, strongly suggests a connection between the formation of the black hole and the galaxy itself. [105]
Simulation of gas cloud after close approach to the black hole at the centre of the Milky Way.[106]Currently, the best evidence for a supermassive black hole comes from studying the proper motion of stars near the center of our own Milky Way.[107] Since 1995 astronomers have tracked the motion of 90 stars in a region called Sagittarius A*. By fitting their motion to Keplerian orbits they were able to infer in 1998 that 2.6 million solar masses must be contained in a volume with a radius of 0.02 lightyears.[108] Since then one of the starscalled S2has completed a full orbit. From the orbital data they were able to place better constraints on the mass and size of the object causing the orbital motion of stars in the Sagittarius A* region, finding that there is a spherical mass of 4.3 million solar masses contained within a radius of less than 0.002 lightyears.[107] While this is more than 3000 times the Schwarzschild radius corresponding to that mass, it is at least consistent with the central object being a supermassive black hole, and no "realistic cluster [of stars] is physically tenable."[108]

Also if you watch "Through the Worm Hole" there's a whole episode on black holes. They spend time with a lady who does nothing but look for black holes for decades. She (as above) can tell where they are by the movements and orbits of stars. Not to say the pictures of one destroying a star aren't greatness. But it's not like this is the final "proof" they are really out there.
And you didn't answer my question. Can Jesus go hang around an event horizon and play horseshoes or not?

You don't think Jesus or Allah could pull it off?

(53,410 posts)and actually if you're trying to make some point about believing in God or being an Atheist you're doing both a disservice. Your questions are stupid and meaningless. Are you even trying to make some kind of point? Or are you claiming in your all knowing of all answers way that the story of Peter Pan is the same as the Bible?
I do know one thing. You don't fucking know any more than anyone else does, what the Truth is.

If you aren't asking these questions that's where people just go to blind faith. Blind faith in a couple thousand year old books written by men who thought earthquakes were the vengence of some superior being.

(58,349 posts)This computer-simulated image shows gas from a shredded star falling into a black hole. Some of the gas also is being ejected at high speed. Astronomers observed a flare in ultraviolet and optical light from the gas falling into the black hole and glowing helium from the star's helium-rich gas expelled from the system.

Thanks for the thread, hue.

(10,618 posts)...there was a civilization on a planet orbiting that star. Imagine how they felt as they realized their entire planet was doomed.
Now imagine how earthlings feel about dooming their own planet with toxic waste, radiation, and global warming. Oh, that's right. Nobody on this planet gives a damn!

(37,748 posts)My sense of awe and wonder are set to overdrive when I start thinking about how incredibly vast space and time really are, and the absurdly huge amount of force surrounding and controlling them, the unlimited boundaries we often often merely pretend to have even the tiniest bit of knowledge of.
I enjoy being small and insignificant-- less pressure at parties that way.
