THE OBSERVABLE WORLD

ACCORDING TO THE Big Bang theory, the universe came into being in one single moment—a cosmic cataclysm that gave birth to black holes, brown dwarfs, matter and dark matter, energy and dark energy. It gave birth to galaxies and stars and moons and suns and planets and oceans. It’s a hard concept to hold on to—the idea that there was a time before us. A time before time.

In the beginning there was nothing. And then there was everything.
