Hello again

Still do not know any pictures that i would like to post.

The mysteries of light still astound me.

There are so many misconceptions about light, and where there may be an absence of light.

Is there something about light that actually holds the universe together?

Apparently there are many more objects known as ‘Black Hole’ than we ever imagined.

How much gravity is produced by these Black Holes, and by light itself?
