Quotes About Cosmology

It is necessary to posit something which is necessary of itself, and has no cause of its necessity outside of itself but is the cause of necessity in other things. And all people call this thing God.

I would hope that the publicity around the Higgs boson would increase the public awareness of physics and cosmology.

Life starts from a white hole and ends in a black hole.

Roosevelt followed it8 with a quirky essay in The Outlook entitled "Dante and the Bowery," arguing that literary stylists had grown too precious in eschewing contemporary imagery. There was as much epic grandeur and poignant example to be found in modern life, he suggested, as there was in Greek myth, or for that matter, thirteenth-century cosmology.

The physicist's picture of the world encompasses the entire sweep from future to past. The junction between the two, that minuscule ring of the present that matters so much to us, has no distinctive theoretical role.

If the universe sprung into existence and then expanded exponentially, you get gravitational waves traveling through space-time. These would fill the universe, a pattern of echoes of the inflation itself.

The waves travel with the velocity of light and slightly squeeze and stretch space transverse to the direction of their motion. The first waves we measured came from the collision of two black holes each about 30 times the mass of our sun.

No one knows who wrote the laws of physics or where they come from. Science is based on testable, reproducible evidence, and so far we cannot test the universe before the Big Bang.

You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.

Among the questions we have in mind: dark matter, antimatter, and matter symmetry.

'What was there before the Big Bang?' That's a question that both kids and adults love to pose to anyone who seems sympathetic. After all, if the universe has only been around for roughly 14 billion years, isn't it legitimate to ask what was in existence before the mother-of-all-events cranked up the cosmos?

If there's no limit to how big the entropy can get, then you can start anywhere, and from that starting point, you'd expect entropy to rise as the system moves to explore larger and larger regions of phase space.

De wortel is metafysica, de stam is fysica en de takken die daaruit voorkomen, zijn alle andere wetenschappen.

Our faith became a competitive theology with various parochial theories of salvation, instead of a universal cosmology inside of which all can live with an inherent dignity.

Multiverse theorists are certainly stark mad. They cannot make a worm, yet they will be making entire universes without a second thought.

If gravity were somewhat stronger or weaker, stars wouldn't exist, and neither would you. And the same can be said of other constants of physics. Several have to be 'just right.'

I'm a cosmologist. All I do is cosmology.

I've been working in cosmology since 1964.

It is embarrassingly unscientific to speak of anything creating itself from nothing.

Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there a countable tally of all the galaxies that exist, even beyond the ones we can see? Or is it infinite? The latter possibility is still on the table.

Literally, there is a lot of talk about sparks in the Kabbalah. It talks about when God created the world initially, there was an explosion that happened like a Big Bang but based on vessels and light.

It is crazy to postulate a trillion (causally unconnected) universes to explain the features of one universe, when postulating one entity (God) will do the job.

They made solemn pronouncements about conditions a trillionth of a second after the Big Bang, on the basis of computer models, which they had produced with computers not even bright enough to talk, let alone understand speech. They were unlike all the generations before theirs in several ways, but chiefly in that they had no faintest clue how ignorant they were. Previous ages had usually had a pretty good handle on that.

The Aztecs had believed the world would end in one of four ways: earthquake, fire, flood, or jaguars falling from the sky.
