The Necessary Universe

KEYWORDS: nature; cosmology; cosmos; relativity; space-time; universe

The Lord created me the beginning of his works,
before all else that he made, long ago.
Alone, I was fashioned in times long past,
at the beginning, long before earth itself.

Proverbs 8:22-3 (New English Bible)

Fair are others: none beholds Thee;
But thy voice sounds low and tender
Like the fairest, for it folds thee
From the sight, that liquid splendour;
And all feel, yet see thee never,--
As I feel now, lost for ever!

Percy Bysshe Shelley

Relativity and Cosmology

I want to emphasize there is a Hubble constant!

Allan Sandage

Cosmology is often wrong, but it is never in doubt.

Lev Davidovich Landau

Oh! let us never, never doubt
What nobody is sure about!
