How the Universe Came from Nothing
Why is there something rather than nothing? For starters, why do we think nothing is a more natural state than something? Physicists are answering old questions in brand new ways.
What's the Latest Development?
Physicists are changing how we think of empty space, i.e. a vacuum, to explain how the universe could have come from 'nothing'. Empty space, it turns out, may not be empty at all. One of the leading proponents of this view, cosmologist Lawrence Krauss, distinguishes between three different kinds of empty space. One, which the Greeks knew, is a space where nothing is seen to exist but which we now understand to be teeming with energy and magnetism. From there, things get strange, then they get incredibly strange.
What's the Big Idea?
A second empty space is vacant of even space and time. In this empty space, entire universes could pop in and out of existence. The phenomenon, known as the Casimir effect, accounts for the energy that bubbles up even in a vacuum. The third kind of nothingness, or empty space, is one in which laws of physics are absent. Here, Krauss appeals to the theory of the multiverse, "a nearly infinite assemblage of universes, each with its own randomly determined rules, particles and forces," representing the solutions to string theory equations.

We're talking Ghost in the Shell type of stuff.
Maybe you watched Ghost in the Shell and maybe afterwards you and your friend had a conversation about whether or not you would opt in for some bionic upgrades if that was possible - like a liver that could let you drink unlimitedly or an eye that could give you superhuman vision. And maybe you had differing opinions but you concluded that it's irrelevant because the time to make such choices is far in the future. Well, it turns out, it's two years away.
Tragedy in art, from Ancient Greece to Breaking Bad, resists all our efforts to tie reality up in a neat bow, to draw some edifying lesson from it. Instead it confronts us with our own limitations, leaving us scrabbling in the rubble of certainty to figure out what's next.
- Why democracy has been unpopular with philosophers
- Tragedy's reminder that the past isn't finished with us
- …and why we need art in the first place
