Describe your life in an alternate universe.
Life in a different universe, as depicted in theoretical physics and science fiction, could range from subtly different to utterly alien, depending on how the laws of physics and history diverge. While some might feature near-identical versions of our world, others could have vastly different physical laws, leading to entirely different forms of matter, energy, and even the possibility of life itself. Physicists propose that in some universes, life might not even exist due to fundamental differences in particle interactions.
