Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.

In this sense, science, as physicist Steven Weinberg has emphasized, does not make it impossible to believe in God, but rather makes it possible to not believe in God.

The universe has a much greater imagination than we do, which is why the real story of the universe is far more interesting than any of the fairy tales we have invented to describe it.

The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.

We now know that we are more insignificant than we ever imagined. If you get rid of everything we see, the universe is essentially the same. We constitute a 1 percent bit of pollution in a universe . . . we are completely irrelevant.

Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
