In 2018 a black hole was observed to swallow a star and now it's vomiting it back up
It’s not significant news when a black hole shreds and consumes a star — that’s just what black holes do. However, when that black hole starts ejecting material from a star years later, then scientists start paying attention. Scientists were recently caught by surprise when a black hole in a galaxy located 665 million light years away exhibited this exact phenomenon.

In 2018, the black hole consumed a star about one-tenth the mass of our Sun. While it’s normal for black holes to fling some of the consumed star material back into space, it usually happens during or shortly after the consumption event. Sending the outflow back into space several years later has been unheard of until now.

trust the science.....


"nothing can escape the pull of a black hole...."


Oh wait, maybe it can. That was yesterday's science.

What’s also interesting about this TDE is that the black hole is spitting out material at 50% of the speed of light. Yvette Cendes, a research associate at the Center for Astrophysics, explains that 10% of the speed of light is the normal speed for black hole outflow. So, not only is the BH spewing out star material years later, but it’s doing so at a much faster rate than normal.

waitwhat

how do they even know its the same material/star that's coming out?

Maybe black holes are sentient and do what they want. Who knows?

What’s more interesting is the fact that they said it happened 3 years after being consumed and they don’t know why.

The 3 years is a significant piece of a puzzle because it was likely auto ejected immediately but due to the bending of time to the observer it appeared to be 3 years.

As an object enters the event horizon at the speed of light it will appear to freeze in time.

This may be an indication of the slow down in time that gives the appearance to freeze. Since the event is happening almost instantly the time delay is about 3 years.

Not one article I have read or discussion I have seen mentions this point.
