> you can only see stars around the edges, not in the center part at all


Firstly Barnard 68 is a molecular cloud.

Have you ever seen a fucking cloud? I'll explain some baby physics to you.

>what is gravity

The edges of the cloud have a weaker gravitational attraction than the molecules closer to the centre.

Molecules on the outside are far apart, not dense -> lets a lot of light through

Molecules on the inside are close together, dense -> blocks a lot of light

Molecules inside you are infinitely close together, you are really fucking dense -> you will never see the light
