Giant Black Hole Shreds and Swallows Helpless Star

What they meant anyway was that momentum is conserved.

Black Hoe tried to swallow me, bro!

[central_va]

you’re innocently committing a fallacy by assuming it’s still there. you’re essentially looking into the past. it is likely gone by now.

THis crap always confuses me. Ok it happened 2.1 B yrs ago. That says nothing about the age of the consumed star in question it could of only been a million years old for that matter.

Could that be construed as domestic violence? Will our local bipartisan government receive more federal funding to support such victims?

[hinckley buzzard]

Because the laws of physics dictate that energy must be conserved, the rest of the star shot away from the black hole at enormous speed.

Now there is a development I'd not heard of before. Fascinating.

[Charles Martel]

Ok if the flare's light took 2.1 billions years to reach earth then the star has to be AT LEAST 2.1 billion years old right? THe story reports the star is only a billion years old.....

"Oh, dear. Have I made an error in time?

How... fallible of me!"

[Mister Da]

Looks like an infrared closeup of Rosie O’s tongue snatching a fly from the air.

Meanwhile, our black hole is devouring the private sector.

[Getready]

don’t the law of physics breakdown at black hole “singularities”?
Why wouldn’t all of the star go into the black hole?
Why ain’t the black hole sucking all of the matter in from
all of the stuff in “space” which really ain’t that empty,
including the “stripped star”(no jokes here puhleeze.)

How did all these black holes start in the first place. I
always was told they bring “everything” into it’s venue over
the “event Horizon” and what’s gonna stop it? Only one star
every coupla eons...sounds strange...since the shape of
space is supposedly affected by mass, wouldn’t that cause
more stuff to be “funneled into the black hole?

Oh, well I just couldn’t master differential calculus, and
aal the other maths I would have needed to figure those things
out....

Good catch! From the 4th paragraph of the ScienceNOW story:

"...the black hole is about 3 million times more massive than our sun..."

I went to the abstract linked in the 4th paragraph

:"The black hole has a mass of about two million solar masses..."

He must have been a journalism najor. You must be able to count in most of the sciences.

[MadMax, the Grinning Reaper]

Nope. It was Whoopi Goldberg and (fill in the blank).

How about Wanda Sykes and any one of her partners?

I was going to write that too, but I was busy with a prior comment. In physics you always have conservation of energy and conservation of momentum. Even though there's no physical contact, think of recoil from a firearm when it's shot.

[calljack]

Of course there is physical contact. The bullet is in the chamber touching something or else the slug would go forward and the casing would go backward. The bullet goes forward and the backward force is transferred through the casing into the firearm mechanism, some of which might be used to activate a semi auto feature and the rest going into your wrist or your shoulder.

[neverdem]

Of course there is physical contact.

Between the black hole are the star? There's a gravitational force field, but that's about it.

Oh ... snap.
From the headline I thought Whoopie Goldberg was dating Ted Danson again.

[hattend]

The star could have been just a billion years old and it and the black hole are 2.1 billion light years away.

The two are not mutually exclusive.

The star was “born” and then killed by the black hole over its billion year lifecycle at 2.1 billion years distance.

I would assume they use the lifespan of other similar stars to determine how old this one star was. They obviously wouldn’t have seen it until the flare of it’s death

The black hole and the star are indeed 2.1 billion light years away, however, the star was just a bunch of hydrogen gas until gravity pulled it into a ball and it ignited a billion years ago.

[calljack]

I was talking about the firearm example
