Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?

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

According to String Theory, what appears to be empty space is actually a tumultuous ocean of strings vibrating at the precise frequencies that create the 4 dimensions you and I call height, width,...

A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like...

Without these supernova explosions, there are no mist - covered swamps, computer chips, trilobites, Mozart or the tears of a little girl. Without exploding stars, perhaps there could be a heaven, but...

It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase.

You are exporting disorder {in the form of heat into the Universe} now as you read this book. You are hastening the demise of everything that exists, bringing forward by your very existence the...

If you ever start taking things too seriously, just remember that we are talking monkeys on an organic spaceship flying through the universe.

Stars, too, were time travelers. How many of those ancient points of light were the last echoes of suns now dead? How many had been born but their light not yet come this far? If all the suns but ours...

God created… light and dark, heaven and hell - science claims the same thing as religion, that the Big Bang created everything in the universe with an opposite. Including matter itself, antimatter

Do you know how I picture God myself?" he said. "As an enormous, creative organ beyond our ken, who scatters millions of worlds into space, just as one single fish would deposit its spawn in the sea....

Each being in the universe yearns for the free energy necessary for survival and development. Each existence resists extinction. The consequent history of violence in the universe is as inevitable as...

From what we cannot hold, the stars are made

All that we think and know is an illusion. Nothing exists. Everything is an opinion.

Who do we think we are - we small creatures with three - pound brains, a few limited senses, and life spans barely long enough to get to know our neighborhood, much less the planet, and much less the...

Overhead, without any fuss, the stars were going out.

Fifth is Q, the amplitude of the irregularities in the cosmic microwave background, which equals 10

Hinton spent most of his adult years trying to visualize higher spatial dimensions. He had no interest in finding a physical interpretation for the fourth dimension. Einstein saw, however, that the...

Light gave birth to the existence. Existence gave birth to reality. Reality gave birth to eternity. Eternity gave birth to time. Time gave birth to life. The past gave birth to the future. The future...

People who believe themselves ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the cosmos. And therein lies a fascinating dichotomy....

In the beginning, there was physics.

The infinite zero of a black hole - mass crammed into zero space, curving space infinitely - punches a hole in the smooth rubber sheet. The equations of general relativity cannot deal with the...

Every second the Universe divides into possibilities and most of those possibilities never happen. It is not a uni - verse - there is more than one reading. The story won't stop, can't stop, it goes...
