Synopsis

Size doesn't matter

When it comes to the size of the cosmos, just remember that it's not size but how you bluff it that matters. True bluffers won't bother about the size of the Solar System. It's too small. Things are always colliding with each other.

Size does matter

While Galileo got by with a lens the size of a mandarin orange, today's astronomers scour the heavens using mirrors that range from the size of an average swimming pool to a new class of telescopes destined to exceed tennis court size?one of which is sited in Chile and aptly named the Very Large Telescope (VLT). Cosmologists are happiest when stating the obvious. Another one in prospect is of football-field proportions, and known as the Overwhelmingly Large Telescope (OWL for short).

Measure for measure

The Hubble trouble that sabotaged the $1.5 billion space telescope project was an error of 1.3 mm (.05 inches), and it required a space mission to fix it. More recently, instructions using imperial instead of metric measurement sent a Mars probe into oblivion.

Condensed milk

All the stars seen in the night sky are in Earth's home galaxy, which got its name, Via Lactea, from the Romans who, lacking imagination, simply borrowed the name from a Greek myth involving the breast of a goddess spurting milk across the sky.
