In recent decades, science has uncovered evidence that if the universe had been forged with even slightly different properties, life as we know it would be impossible. Small tweaks to our universe’s composition could erase the periodic table, disintegrate particles, and remove all the traces of structure in the cosmos. The fine-tuning of the universe for life is a major unsolved problem in the world of physics. Luke will introduce the science, and show how it leads to deep questions about our cosmos.
