So far, we've learned a lot about smaller black holes,
but why let them have all the fun?

2
00:00:05,333 --> 00:00:12,000
Larger ... well, MUCH larger black holes can be just as social,
but their situation is ... a little bit different.

3
00:00:12,000 --> 00:00:17,333
If we take a closer look, we can see that some of these
black holes really LOVE being the center of attention.

4
00:00:17,333 --> 00:00:23,500
Because they're so massive, they can gather up not just a bunch of
gas and dust, but also, well, friends!

5
00:00:23,500 --> 00:00:30,250
In fact, they can pull in a LOT of company,
including stars, neutron stars, and even smaller black holes!

6
00:00:30,250 --> 00:00:33,333
You'll often find these social gatherings in the centers of galaxies,

7
00:00:33,333 --> 00:00:38,833
where some of the black holes even launch giant,
powerful jets into space, just like their smaller cousins.

8
00:00:38,833 --> 00:00:46,250
Now, what about the black hole's friends? Well, if they’re far away,
many of them are content to simply zoom around in a long, lazy dance.

9
00:00:46,250 --> 00:00:50,083
However, as some get closer, things can get …
a little weird.

10
00:00:50,083 --> 00:00:55,083
For example, if some stars get too close, they can potentially
get completely pulled apart!

11
00:00:55,083 --> 00:01:00,750
In other cases, if the friend is a neutron star or another black hole,
and IF it somehow gets REALLY close,

12
00:01:00,750 --> 00:01:04,083
it can get sent off on a bizarre-looking dance around the black hole …

13
00:01:04,083 --> 00:01:07,916
and eventually crash into (and merge with) its big companion.

14
00:01:07,916 --> 00:01:12,750
Of course, these are just a few examples, and depending on
the size of the friends … and the black hole,

15
00:01:12,750 --> 00:01:15,500
things might actually, uh … be … erm …

16
00:01:15,500 --> 00:01:18,166
Ah, friendship! So complicated.

17
00:01:18,166 --> 00:01:25,583
Anyway, if you're looking for a fun night out with lots of company,
grab your telescopes and look no further than these giant black holes.
