the shocking revelation that empty space indeed has energy—and enough energy in fact to dominate the expansion of the universe.

light is an electromagnetic wave.

Light is an electromagnetic disturbance propagated through the field according to electromagnetic laws." With

For those who like to quote Aristotle's wisdom when appealing to his "Prime Mover" argument for the existence of God, let us remember that he also claimed that women had a different number of teeth than men, presumably without bothering to check.) Everything

When it comes to understanding how our universe evolves, religion and theology have been at best irrelevant.

We live at a very special time. . . the only time when we can observationally verify that we live at a very special time!

This makes it sound as if light has intentionality, and I resisted the temptation to say light considers all paths and chooses the one that takes the least time because I fully expect that Deepak Chopra would later quote me as implying that light has consciousness.

The universe is the way it is, whether we like it or not. The existence or nonexistence of a creator is independent of our desires. A world without God or purpose may seem harsh or pointless, but that alone doesn't require God to actually exist.

Nevertheless, the declaration of a First Cause still leaves open the question, "Who created the creator?" After all, what is the difference between arguing in favor of an eternally existing creator versus an eternally existing universe without one?

The central problem with the notion of creation is that it appears to require some externality, something outside of the system itself, to preexist, in order to create the conditions necessary for the system to come into being. This is usually where the notion of God—some external agency existing separate from space

La realidad debe primar sobre las relaciones públicas, pues no se puede engañar a la naturaleza.   RICHARD P. FEYNMAN (1918-1988)

one's universe would appear very different from the vast bulk of space around it, which would still be inflating. In this picture, inflation is eternal. Some regions, indeed most of space, will go on inflating forever.

he realized that he could get an approximate answer that was "good enough" in a short time

A universe without purpose should neither depress us nor suggest that our lives are purposeless. Through an awe-inspiring cosmic history we find ourselves on this remote planet in a remote corner of the universe, endowed with intelligence and self-awareness.

nuestro universo desaparecerá tan abruptamente como, probablemente, empezó.

the remaining 70 percent of the total energy in the universe resided not in any form of matter, but rather in empty space itself.

Maybe all of the mysteries of particle theory can be solved by invoking the same mantra: if the universe were any other way, we could not live in it.

There are areas of philosophy that are important, but I think of them as being subsumed by other fields. In the case of descriptive philosophy, you have literature or logic, which, in my view, is really mathematics.

When a person's religious beliefs cause him to deny the evidence of science, or for whom public policy morphs into a battle with the devil, shouldn't that be a subject for discussion and debate?

Donald Trump called for the closing of borders to Muslims; John McCain said, in response to the President's address on the San Bernardino shooting, that 'this is the war of our time.' As that shooting shows, we react to terrorism with far more intensity than we do to an ordinary crime.

These days, gun violence can strike anywhere, from a church hall in Charleston to a movie theatre or a Planned Parenthood office in Colorado. But our response to it depends on whether that violence is understood to be terrorism.
