In his latest book, the Nobel Prize winner Steven Weinberg explores how science made the modern world, and where it might take us from here.
Multiverse Collisions May Dot the Sky
Early in cosmic history, our universe may have bumped into another — a primordial clash that could have left traces in the Big Bang’s afterglow.
In a Multiverse, What Are the Odds?
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics.
At Multiverse Impasse, a New Theory of Scale
Physicists have begun to explore the idea that mass and length may not be fundamental properties of nature. The hypothesis could help to avoid the conclusion that our world is just a weird bubble in an endlessly foaming multiverse.
