The Milky Way May Have a Disk of Black Holes

Computer models are helping scientists on the hunt for small black holes and new data is giving us a better understanding of the universe’s largest explosions.

Hey, these are my colleagues who authored the first paper you mentioned!!

[Master_Therion]

1:51 "Black holes got pushed into one plane." With orbital mechanics and conservation of angular momentum, I can see how that would happen. But the real question is, how did they get through airport security?

[OverlordZephyros]

Could there be habitable planets, even life, in the galactic center?

What would the night sky look like?

[mikerphone.]

If you're going to put a perfectly good telescope in chile, you should at least serve it over fries.

[cybersans]

Ii really thought he was going to say "that's a lot of damage"!

[rkpetry]

*_...no mention of what that horde of black holes does to larger stars settling toward the galactic core hole—10k 6 mi. dia. holes plowing-through-ripping-up 10⁶ mi. dia. giants…_*

This guy is the Chuck Woolery of YouTube. He hosts every show

[PuzzlesExplained]

Woah, never really noticed the intro on SciShow Space. I actually really like it in that 3D style, even though it differs from the other SciShow intros.

Oh and nice video lol

Every time I watch things like this I get dizzy at trying to comprehend the vastness of space. It really is mind boggling. Apparently the sky we can see with the naked eye represents a small circle on the edge of the Milky Way galaxy. Another interesting fact is that some astronomers aimed a telescope at one of the darkest patches in the night sky, the size of a small dot in the sky, and found that it contains millions of galaxies. Galaxies, not stars. I have no doubt that the universe is filled with life, and civilisations, but that we are all far too far apart from each other to ever have a chance of finding each other.
This does not even take into account the time issues. The earth has been around for 4.6 billion years, the universe for 13.7. Humans have been capable of transmitting and receiving radio signals for 100 years or so. It's not just a question of aiming our signals and receivers at the right star system out of all the uncountable possible star systems that exist, but also doing it at the right time, that narrow window in which a civilisation could possibly have existed capable of sending out signals. What are the odds that we are pointing it at the right system at the right time? Those signals may have already passed us by millions or billions of years ago, or they may never reach us because the space in between us is expanding faster than the signal can travel. I doubt we will ever find other advanced life.

Hey Hank, did you stand in the sun for 5 minutes? You look all sunburnt! 😆

Perhaps they can use the mini flash as an indicator as to direct obversations to the main event, for LIGO and other detectors. Athough, of course, LIGO doesnt need to be aimed.

[The_Angry_BeEconomist]

so basically the astronomical equivalent of a star lighting its own fart @4:00

[OriginalPiMan]

Amateur here, but I'd have thought it fairly obvious that black holes with masses in the same ranges as large stars would behave similarly to those large stars, in terms of how they move thanks to gravity.
A black hole with mass X has the same gravitational effects as a star of mass X at any point further from the centre than the star's radius. The density of the object only matters once you get close.

[BrookMonroe]

There aren't any black holes with masses like the Sun's. The minimum mass requirement for black hole creation starts at 4x the Sun's mass. It's not an order of magnitude, but it is significantly larger.

[jbtownsend]

I thought we already established there is gas, black holes, AND a ring, around Uranus. Can we get some real news around here?!

[maxcovfefe]

Maybe it'd be cool if we could get our sun to act like an intergalactic spaceship that could soar from galaxy to galaxy with our solar system in tow.

[lejink]

I’ve always wondered what happens to a neutron star that’s rotation exceeds its gravity’s ability to hold it together (I’ve watched some videos about pulsars that rotate so quickly they’re actually wider at the equator)
If it fly’s apart, what elements would result? Could we find neutron star clumps floating around

[flamencoprof]

Surprise, surprise, the largest sources of gravitational attraction are gravitationally attracted together.

[angelogforte]

Good to see ya back hank hope you enjoyrd your holiday? Haahaa

[kca_randy]

In other black hole news .... Is an awesome phrase.
