Description:
It's a little known fact that black holes are very shy creatures. Reticent, really. They'd rather stay out of sight, out of mind, thank you very much. And another thing, they don't appreciate when you talk about them behind their back, just because they're shy, doesn't mean they're not sensiti..... Sorry, what'd you say? Oh. That's not the reason scientists can't see them? Well, let's figure out the real reason together.

And here's your Shmoop du jour, brought to you by black holes.

Now you see 'em, now you don't. Yeah.

And our question:
- 00:19
Scientists cannot see black holes because...

- 00:27
All right, well, most of our science projects
- 00:29
involved Mentos and Diet Coke...
- 00:32
but we can still answer this question.
- 00:34
We can rule out A right away because the paragraph
- 00:37
tells us that black holes are fairly common.
- 00:40
And answer B can be ruled out because the paragraph states
- 00:42
that their effects can be observed.
- 00:44
So even though scientists can't see them, we know they exist,
- 00:47
like playing a game of hide and seek with a very acrobatic elephant.
- 00:51
This leaves us with answers C and D.
- 00:53
The paragraph does not mention us not having the technology
- 00:56
to see black holes, so we can eliminate C.
- 00:58
Which means that D has to be the right one.
- 01:01
Scientists cannot see black holes because they absorb all light.
- 01:05
Human vision is only possible when light can be reflected,
- 01:09
so we'll never see a black hole directly,
- 01:12
just its effects.
- 01:14
Like, you know, it sucks in the light and matter
- 01:16
from everything around it. So it's like it all disappears
- 01:18
into this black hole. That's probably what Einstein meant.
