Quotes About Cosmology

Something pretty mysterious had to give rise to the origin of the universe.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

The original project began because we know the universe is expanding. Everybody had assumed that gravity would slow down the expansion of the universe and everything would come to a halt and collapse. The big surprise was it was actually speeding up.

This fact immediately suggested a singular event - that at some time in the distant past the universe began expanding from an extremely small size. To many people this inference was loaded with overtones of a supernatural event - the creation, the beginning of the universe.

I've always really been into science, and in the last five years I've gotten into theoretical physics and the origins of the universe.

I believe we exist in a multiverse of universes.

We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.

According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.

As scientists, we track down all promising leads, and there's reason to suspect that our universe may be one of many - a single bubble in a huge bubble bath of other universes.

Although we don't know what is outside our universe, astronomers still wonder. Several pictures of what there might be have been dreamed up. An interesting one, called multiverse, has lots of universes. Picture it as a foam of bubbles. Our universe would be one bubble, and we'd be surrounded by lots of other bubbles.

There may have been many big bangs, one of which created our universe. The other bangs created other universes.

'Eternal inflation,' as it's called - the endless generation of new universes - may be a hyper-cosmic imperative. It seems that it must happen.

I don't even really know what the big bang is, and so when people want to go through and say, 'Well, I believe that the universe started by God starting it,' that's fine by me.

A static universe isn't physically self-consistent.

The striking discoveries of contemporary science are continually telling us new things about how material creation came to be and how it continues to evolve. Although we do not have all the answers, we are clearly going in a direction that transcends the cosmology in which the great world religions came into existence. Our vision, understanding, and our attitudes about God inevitably must change.

Nothing cannot exist forever.

There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.

Back in 1917, when Einstein had analyzed the "cosmological considerations" arising from his general theory of relativity, most astronomers thought that the universe consisted only of our Milky Way, floating with its 100 billion or so stars in a void of empty space.

Partly as a result of vivid allegorical readings of Homer, the grotto of the nymphs in the Odyssey gets cosmologically extended in meaning, as in the De antro nympharum of Plotinus's student Porphyry, where cos- mos and cave exist for each other. The one is the symbolon of the other, and man is the tertium, who is prevented by temptation and gentle force from reaching his cave-transcending destiny.

A cosmology that admits of only one male god limits women's capacity to envision their full potential as human beings.

If infinities are signs of missing unification, a unified theory will have none. It will be what we call a finite theory, a theory that answers every question in terms of sensible finite numbers.

I'll describe the original approach of Barbour, but most of what I'll have to say applies to Gomes's version9, as well as more recent work of Barbour and his collaborators. A moment, for them, is a configuration of the universe as a whole. These configurations, according to Barbour and Gomes, are relational configurations, which code all the relations that can be captured in a moment, such as relative distances and relative sizes.

In practice, the greatest amount of information that may be stored behind a horizon is huge - 10^66 bits of information per square centimetre.

Metaphysics is the clearing house for all fundamental philosophical problems.
