Would a black hole lose mass if it accreted anti-matter? 🧪🔭

If you had a black hole with the mass of the whole known universe, how big would that black hole be? 🧪🔭

When two black holes merge, what happens to the singularity? Do they both exist within the event horizon? Love Matt’s reaction to this question! 🔭🧪

Do black holes accrete dark matter? 🔭🧪 Let's find out:

What is actually spinning if the centre of the black hole is a singularity? 🔭🧪

Do black holes look the same from different angles? 🔭🧪

Maddie explains:

New on our YouTube channel: the Black Hole Hunters team answer questions from our Zooniverse volunteers www.youtube.com/watch?v=J5fd... 🔭🧪

How does a star end up orbiting a black hole? 🧪🔭

Here’s Matt:

How do we make a black hole? Let Maddie and Matt explain 🧪🔭

What's it like spending your days searching for black holes? The Black Hole Hunters team talk about their work and what makes black holes so interesting 🔭🧪

Black Hole Hunters is now available in Japanese! Thanks to Zooniverse volunteer InoSenpai for providing the translations. www.zooniverse.org/projects/cob... 🔭🧪

There are millions of black holes in our Galaxy, but astronomers only know about less than 100 of them. Where are all the missing black holes? 🧪🔭 youtu.be/ZevfYc8_gnA

Shoutout to a crossover project alert! A volunteer on the Black Hole Hunters project proactively identified potential eclipsing binary candidates while analyzing TESS lightcurves. Science thrives on these unexpected connections! @adammc.space @blackholehunters.bsky.social

Posting this again because the 🧪🔭 feeds were having issues when I posted it the other day.

Do you want to be part of something huge? Check out this introduction to the Black Hole Hunters project and find out how you can help us search for the Galaxy's missing black holes www.youtube.com/watch?v=mtDk...

Today I'm simulating radial velocity measurements of black hole/star binary systems. The black holes aren't visible, but it's possible to see the orbital motion of their stellar companions. For @blackholehunters.bsky.social we need to know which candidates we can most easily confirm 🔭🧪
