Economy 52,861 Posted November 28, 2019 Share Posted November 28, 2019 https://www.straitstimes.com/asia/east-asia/scientists-spot-black-hole-so-huge-it-should-not-even-exist-in-our-galaxy A black hole with 70 solar masses (over twice as massive as the upper limit thought possible from typical black holes) has been discovered in the Milky way Galaxy This is a bit puzzling for scientists because typically there are 2 types of black holes... There are the stellar black holes created from the collapse of super massive super Nova which typically do not exceed 20 solar masses at most... Then there are the super massive black holes that can be millions of solar masses and usually exist at the centre of galaxies. The origin of super massive black holes is still up for debate But case and point, blackholes have always been either the smaller stellar black holes or the super massive, never something in between... In theory a supernova should not create a black hole of this mass but it is far too tiny to be a super massive black hole making its origins puzzling and up for debate Link to post Share on other sites More sharing options...
27monster27 15,869 Posted November 28, 2019 Share Posted November 28, 2019 Well, since it is a bit too small to be an intermediate mass black hole, I assume that it possibly could have been a stellar mass black hole that ate up enough mass that allowed said black hole to be that dense. he/him/his Link to post Share on other sites More sharing options...

That's what I was thinking but I feel like if the answer was that simple scientists wouldn't be making a thing about it It would have to eat up A LOT of mass to grow to that size... I think part of the reason this doesn't make sense is that the only areas of the galaxy with enough mass density to fuel a black hole to this size would be near the core, but then near the core a blackhole would simply be attracted to the super massive black hole and be gobled up In essence, a blackhole this size isn't supposed to exist, at least not in our galaxy... Yet it does Link to post Share on other sites More sharing options...

It's certainly a possibility... But they would have to by coincidence both be in the upper limits of what a Steller blackholes in our galaxies mass density should be able to go up to and they would coincidentally have to run into eachother... They also couldn't originally be from the same area otherwise if they were competing for matter they wouldn't have gotten so big so presumably they would have to run into eachother coming from opposite directions It's a possible explanation but a lot of unlikely coincidences would of had to happen... Curious to see what they make out of this as time goes on Link to post Share on other sites More sharing options...

Nevermind @27monster27 found another article that mentioned a possibility https://www.google.ca/amp/s/www.sciencealert.com/an-impossible-black-hole-has-been-found-in-the-milky-way-galaxy/amp Basically if a black hole managed to form quickly enough after the end stages of a dying star going Nova and the ejected matter managed to be sucked back into the blackhole before being ejected too far to escape it's gravity... This black hole would have a MUCH larger starting mass than most black holes because the entire original mass of the super massive star would fuel the black hole instead of just a small fraction of the dense core giving it a head start to already be bigger even before it gets to accumulate more mass over time An unlikely merge of 2 exceptionally large Steller black holes like you (27monster27) mentioned was indeed also included as a possibility Link to post Share on other sites More sharing options...

Now, a star this large most likely would have made for a far denser black hole, but this could have been photodisintegration. For stars that have the ability to undergo hypernova, the process of photodisintegration plays a large role. The photodisintegration process takes energy away from the explosion, causing a "failed supernova/hypernova". Essentially, a massive stars death without the explosion. he/him/his Link to post Share on other sites More sharing options...
