A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth.
The burst, called GRB 250702B, was first spotted by NASA’s Fermi Gamma-ray Space Telescope in July. Such bursts are bright flashes caused by jets fired out from energetic events, such as massive stars collapsing into black holes or neutron stars merging, and they usually last no more than a few minutes.
GRB 250702B, however, lasted for 25,000 seconds – or about 7 hours – making it the longest-known gamma-ray burst. Scientists had struggled to explain it, but Eliza Neights at NASA’s Goddard Space Flight Centre in the US and her colleagues now suggest an unusual and rare possibility.

I mean... 7 hours isn't that long. Especially depending on the size of the star that was consumed. Even the Sun's light can take thousands of years to actually exit the sun. While sure, gamma rays should have an easier time exiting a star, 7 hours is still a fucking photograph flash to a stellar event...
(also who ever is surprised a black hole would win against ANY star is either playing a fool or fucking braindead)

Not disagreeing, but you're oddly intense about this... you good champ?

Saying, "fuck" twice is hardly being intense.

The wording is not how light from our sun works... Unless you're simplifying greatly. It's not in a maze or some container that takes thousands of years to escape. The light is based on photons that are emitted via nuclear fusion then some mass being converted to energy/photons.
I've read that photons can bounce around (i.e. be absorbed and re-emitted) an estimated 40,000 years... but we all should understand that is a) an estimate and b) an estimate for the inner-most photons. Photons created via near-surface level areas of the sun may be emitted outward from the sun near-instantaneously.
All this to say that the light/photon(s) don't/doesn't start out as light. However, once a photon exists, it may be trapped for thousands of years due to the shear amount of mass trapping it and needing to be absorbed/re-emitted until space-bound!

Greatly simplifying, yes.
The point is the vast majority of stellar scale events are crazy slow compared to what we'd normally assume, because stars are insanely huge. 7 hours is still a flash in the pan.
The black hole didn't just drop straight in. The sun was undoubtedly orbiting the black hole. It'd take time for the matter to even get close enough. 7 hours sounds crazy fast to me.

If minutes is normal for a gamma ray burst, hours is an order of magnitude longer. Still, flash in the pan indeed! Lucky we caught it.

Utterly wrong. The entire point of a black hole is that it IS an infinity from our perspective. Not even light escapes. They break basically every mathematical model we have ... because of infinities.
To a star, it IS infinite, and the fact you do not understand that is ... alarming to say the least.

It IS an infinity ... from our perspective.
Just because you don't understand what those words mean doesn't make me wrong.

The black hole didn't struggle.

For comparison, it usually takes me at least 10 hours to gobble down a whole star. Those gamma rays do a real number on... well, everything in the vicinity, really, but especially my heartburn.

How many samples defined "normal"?

Why is that alarming, is this person a black hole engineer?

BEWARE OF DOG! IT CANNOT FATHOM THE RELATIVE INFINITENESS OF A BLACK HOLE COMPARED TO A STAR!
