ASVAB Paragraph Comprehension 1.3 Detail

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 our question:

00:19

Scientists cannot see black holes because...

00:22

[ mumbles ]

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.
