Of the nature and State of Man, with respect to the Universe

Say first of God above, or man below,
What can we reason, but from what we know?

-Alexander Pope-

Of course those of the Age of Reason had no idea of the size of the universe and the English language has no word to describe just how much bigger the visible universe is in comparison. Indeed they did know that it wasn't as the ancients thought: our floating planet covered by a rotating bowl with lights affixed, above which gods lived -- a bowl so close that it was possible for bronze age people to reach it by building a tower. Intimations they had, that a universe vast enough to include other suns, other worlds, could not have been designed to be a place for humans; a place for humans to dominate; a place designed for no other purpose.
Ask for what end the heavenly bodies shine,
Earth for whose use? Pride answers, 'Tis for mine

The Anthropic Principle suggests otherwise. As Steven Hawking says, it simply states that the suitability of Earth for life on Earth is self explanatory: any form of intelligent life that evolves anywhere will automatically find that it lives somewhere suitable for it. If existence wasn't created for us, that's one less ineffable mystery that needs to be dressed up in godlike robes.

Indeed, 16th century astronomer Jerome Wolf wrote to Tycho Brahe that the "infinite size and depth of the Universe" ( if only he knew how close to infinite it is) was the greatest danger to Christianity. Fortunately for that enterprise, most today still haven't grasped that size and what it says about the irrelevance of Human values and indeed the importance of anything to do with us.

What we've come to know about the nature of reality; about what the meaning of is is, has presented us with a landscape more vast and more inaccessible to the public grasp than is the 14 billion light year fraction of what is that we can see. There are whole dimensions that we can't see and can't come close to comprehending and what we can see and comprehend is little more than the shadows in Plato's cave. That everything in this infinite universe can be attached to a two dimensional membrane floating in 11 dimensional space/time requires more than fasting, chanting, meditation and drugs to become apparent keeps reality well out of the reach of all of us. Certain conclusions about it however, are hard to avoid without avoiding the entire question of just why is is. To my admittedly limited mind, questions of creation, of entities involved with creation, entities beyond the properties of matter and energy and dimension and in what places they exist, are absurd. Isn't it absurd to discuss the number of angels that can dance on a pinhead without being able to ascribe any characteristics or properties necessary to their existence? And of course we cannot without dragging them into a place of scrutiny, which is impossible.

Entia non sunt multiplicanda praeter necessitatum

Said old William, hundreds of years before the Enlightenment; don't create entities if you don't have to, yet we're still doing it. We're still creating creators, plugging the ever narrowing gaps in our ability to explain nature with gods and demons and angels and disembodied spirits, although it's long since become obvious that we don't need gods of gravity or electricity or of the nuclear forces. We don't need gods to determine why and when it will rain or to give purpose to earthquakes and storms or to make it very important to the cosmos that we worship a certain god and avoid another or refrain from sleeping with the wrong people or obtain knowledge reserved for the gods.

Know then thyself, presume not God to scan;
The proper study of mankind is Man

What we see as energy and matter and time are properties of other phenomena, not results of conscious or unconscious entities that create and control them. We don't need to create them to explain what is otherwise explained by what we can demonstrate and we can demonstrate that random fluctuations of that fabric which manifests itself in all things can more easily do what the old consciousness needed to create entities to create.

Stephen Hawking's soon to be released book claims that existence explains itself, that there is no need to invoke entities for which existence contains no place and allows no properties to explain the spontaneous origin or virtual particles or indeed that tiny part of an infinite thing called existence. If indeed, current theory is correct, there are such an infinite number of conditions that can be called universes, inaccessible from one another, all our religions become absurd. In such isness, the creation of ever more universes is an inevitable result of the nature of is. No nebulous incorporeal entities need apply.
And in spite of pride, in erring reason's spite,
One truth is clear: whatever is, is right

M-Theory is hard to grasp. OK, it's damned near impossible, but as theories do, it predicts outcomes otherwise not predictable. Hawking has come to embrace it as it makes the singularities embedded in classical theories nugatory. It makes it unnecessary to postulate something existing before time that caused time to start, for instance. It makes it unneccesary to postulate the entire idea of anything before time.
"It is not necessary to invoke God to light the blue touch paper and set the universe going,"
Hawking writes in the introduction. Indeed, it's no longer necessary to explain the tides, the winds, the orbits of bodies in space, lightening or the nearly infinite number of gaps in our knowledge in which gods once found refuge.

If there are no more gaps for our gods to hide in, no more firmaments to divide heaven and earth, what then will become of them? Perhaps we'll find him in the one place we have never looked. In ourselves. If universes can be self-creating by virtue of physical law, cannot we be self creating in terms of what we wish to be?

History says no, Glenn Beck thinks it leads to death camps, theologians trip over their tongues trying to show how even if there isn't a God or any place for him or anything he could do if he could -- there is a God. Personally I prefer the freedom of knowing nothing matters for very long; nothing a hundred billion years of time won't wash away. I prefer to think that only the free can be moral, only the mortal can be compassionate and only in our transience can we find glory.

A Larger View of Things

Time to put things in perspective. Literally.

Take a look at this nifty presentation, The Scale of the Universe, that takes us from the infinitesimal (the Planck length -- 0.00000000000000000000000000000000001 m -- we are told that any length shorter than that makes "no physical sense" -- sure...)

Simon Hakansson's rendition of quantum foam somewhere on the level of the Planck length.

to the unimaginably vast (the estimated size of the Universe -- 93,000,000,000 light years -- yeah, wrap your mind around that!)

and everything in-between:

Enjoy and marvel.
