Brainlock.

Walking back from the shop the other day I had a moment of deep wonder. It was dusk and the moon was up - I thought, "So that's a planet. And we're on another planet. So how does that all work then?"

I remember as a kid lying in my bed and imagining moving outwards (if even that makes any sense) through space and wondering where the edge was. But if you got there and then went a bit further...............

Re the picture:
"Representing a narrow "keyhole" view stretching to the visible horizon of the universe, the Hubble Deep Field image covers a speck of the sky only about the width of a dime 75 feet away. Though the field is a very small sample of the heavens, it is considered representative of the typical distribution of galaxies in space, because the universe, statistically, looks largely the same in all directions. Gazing into this small field, Hubble uncovered a bewildering assortment of at least 1,500 galaxies at various stages of evolution."

Do you know how big even one galaxy is? The average Galaxy has, wait for it, 100-200 billion Stars most similar to our Sun. Erm, nope, sorry, cannot fathom this.

So, 1500 Galaxies in a part of the sky covered by a dime at 75 feet away and each of the 1500 Galaxies contain 100-200 billion Stars like the Sun?

WWWHHHHHHAAAAAAAATTTTTTTT??????

Look at what HE made!
