A Physicist Defends Imperfection in Our Universe: It’s Essential

We owe our existence, says Marcelo Gleiser, to the fact that our universe is full of lopsided, not balanced, quantities

Philosopher and physicist Marcelo Gleiser, author of A tear at the edge of creation (2013), sees lack of symmetry — lopsidedness — as essential to the nature of our universe: We left-handed people are a minority among humans, roughly a 1:10 ratio. But make no mistake: the Universe loves left-handedness, from subatomic particles to life itself. In fact, without this fundamental asymmetry in Nature, the Universe would be a very different place — bland, mostly filled with radiation, and without stars, planets, or life. Still, there is a prevalent aesthetic in the physical sciences that pushes for mathematical perfection — expressed as symmetry — as the blueprint for Nature. And, as is often the case, we get lost in a…
