The missing link in cosmology is the nature of dark matter and dark energy.

My religion encompasses all religions. I believe in God, I believe in the universe. I believe you are god, I believe I am god; I believe the earth is god and the universe is god. We’re all god.

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.

My first popular book, ‚A Brief History of Time,‘ aroused a great deal of interest, but many found it difficult to understand.

The profoundly ‚atomic‘ character of the universe is visible in everyday experience, in raindrops and grains of sand, in the hosts of the living, and the multitude of stars; even in the ashes of the dead.

In the divine milieu, all the elements of the universe touch each other by that which is most inward and ultimate in them. There they concentrate, little by little, all that is purest and most attractive in them without loss and without danger of subsequent corruption.

Even sleepers are workers and collaborators in what goes on in the Universe.

Philosophers have not kept up with modern developments in science. Particularly physics.

I’m in awe of the universe, but I don’t necessarily believe there’s an intelligence or agent behind it. I do have a passion for the visual in religious rituals, though, even though they may be completely empty and bereft of substance. The incense is powerful and provocative, whether Buddhist or Catholic.

Once you make a decision, the universe conspires to make it happen.

Time can behave like another direction in space under extreme conditions.

Physics has a history of synthesizing many phenomena into a few theories.

M-theory is the unified theory Einstein was hoping to find.

Theoretical physics is one of the few fields in which being disabled is no handicap – it is all in the mind.

There are no black holes in the sense of regimes from which light can’t escape to infinity.

OK, so what’s the speed of dark?

What goes up must come down.

All are but parts of one stupendous whole, Whose body Nature is, and God the soul.

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there are far too many equations to solve. I’m no better than anyone else at understanding what makes people tick, particularly women.

I think perhaps the most important problem is that we are trying to understand the fundamental workings of the universe via a language devised for telling one another when the best fruit is.

The centre of the system of the world is immovable.

To the dumb question, ‚Why me?‘ the cosmos barely bothers to return the reply, ‚Why not?‘

The universe seems neither benign nor hostile, merely indifferent.

It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.

I don’t believe in an outside agent that creates the world, then walks away. But I feel very strongly there is an intelligence at work in every flower, in every blade of grass, in every cell of my body. And it is that intelligence that, I wouldn’t say created the universe. It is creating the universe. It’s an ongoing process.

There is nothing your highest self wants more than peace. This peace makes you feel worthy of all of the richest blessings of the universe, and when you radiate this out into the world, it is returned to you without fail.

To the mind that is still, the whole universe surrenders.

I need physics more than friends.

What goes on inside a star is better understood than one might guess from the difficulty of having to look at a little dot of light through a telescope, because we can calculate what the atoms in the stars should do in most circumstances.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

Religion is part of the human make-up. It’s also part of our cultural and intellectual history. Religion was our first attempt at literature, the texts, our first attempt at cosmology, making sense of where we are in the universe, our first attempt at health care, believing in faith healing, our first attempt at philosophy.

There were several possible solutions of the difficulty of classical electrodynamics, any one of which might serve as a good starting point to the solution of the difficulties of quantum electrodynamics.

The drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has the problem of always teaching techniques, rather than the spirit, of how to go about solving physical problems.

It should be possible to explain the laws of physics to a barmaid.

The cosmos is about the smallest hole that a man can hide his head in.

I had a project for my life which involved 10 years of wandering, then some years of medical studies and, if any time was left, the great adventure of physics.

In a way, the whole tangible universe itself is a vast residue, a skeleton of countless lives that have germinated in it and have left it, leaving behind them only a trifling, infinitesimal part of their riches.

We are an impossibility in an impossible universe.

The universe as we know it is a joint product of the observer and the observed.

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

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.

There happen to be a lot of people around who spent an hour on the Internet and think they know a lot of physics, but it doesn’t work like that… There’s a reason there are graduate schools in these departments.

There is no chance and anarchy in the universe. All is system and gradation. Every god is there sitting in his sphere.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein’s general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

Baseball is a universe as large as life itself, and therefore all things in life, whether good or bad, whether tragic or comic, fall within its domain.

The clearest way into the Universe is through a forest wilderness.

Throughout history, people have studied pure science from a desire to understand the universe rather than practical applications for commercial gain. But their discoveries later turned out to have great practical benefits.

It is reasonable that forces directed toward bodies depend on the nature and the quantity of matter of such bodies, as happens in the case of magnetic bodies.

Before we understand science, it is natural to believe that God created the universe.

I like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe – because, like Spinoza’s God, it won’t love us in return.

Space is almost infinite. As a matter of fact, we think it is infinite.

The universe is very large, and its boundaries are not known very well, but it is still possible to define some kind of a radius to be associated with it.

Everything is perfect in the universe – even your desire to improve it.

Everything in Nature contains all the powers of Nature. Everything is made of one hidden stuff.

The greatest progress is in the sciences that study the simplest systems. So take, say, physics – greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.

Cosmology is a rapidly advancing field.

The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.

The big message of gospel is that you don’t have to keep fighting the universe; you can stop, and the universe is quite good to you. There is a loss of ego.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn’t even nothing or once.

Historically, the stuff of the universe goes on becoming concentrated into ever more organized forms of matter.
