Black holes keep ‘burping up’ stars they destroyed years earlier, and astronomers don’t know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable ‘burping’ bouts. Half of all star-killing black holes may experience the same.

It sounds like the matter isn’t coming out of the black hole, but actually the accretion disc that is in the process of being sucked into the black hole so we aren’t breaking the event horizon threshold as title suggests

It wouldn’t be pop-sci if it didn’t have a misleading clickbait title!

It couldn’t be the actual black hole past the event horizon, right? It would logically seem that inescapable precludes burping or farting matter

scientist quoted as saying black holes were “shitting [their] guts out” and “blowing megachunks all over the proverbial tile floor of space”

This is my assumption. Clearly the accretion disk isn’t the point of no return, or maybe stuff on the inside = past point of no return, stuff on the outside can get flung off?

If I remember correctly the point of no return is called the Event Horizon.

Ok so black holes are just teleporters to other dimensions right?!

It’s a one way teleporter to a single dimension, because you’re entire mass will be a single imperceptible point.

But it’s not a single point though, because blackholes with a different mass have different sizes, so it’s more like a “maximum density” that can exist in this universe…

It’s an oversimplification, but something with the mass of say, a human, will be crushed into a very very very very tiny space. A much smaller space than 0.1mm radius, which would hold Earth’s moon’s mass of 7.342×10^22 kg.

Size and density have non-standard definitions in this context.

As far as i know the Mass of the black Hole is concentrated in the Center (singularity). But it is surouded by its schwarzschild Radius. Anything that enters it cant escape.

Time slows down as the mass approaches the center, so it just can never reach it. It’s stuck in time dilation approaching infinity.

That’s what the current understanding of physics says. But given that there are singularities that come out of the math, all that really means is we don’t actually know what happens inside a black hole.

I equate it to a can of spray cheese. Small hole, puffy cheese.

I thought you were making this up, but apparently there actually is “cheese” that comes in a spray bottle.

What the wiki article does not explain, is why.

It’ll teleport you from the third dimension to the first dimension.

No indication that any of the returning matter ever made it beyond the event horizon but how wild would it be if matter can come back from that somehow, would shatter current understand of the phenom.

It would be amazing if that happened! We desperately need to be proven wrong somewhere if we want to develop a theory of quantum gravity.

So would it be appropriate to say they are passing gas?
