Out of the string theory swampland: New models may resolve problem that conflicts with dark energy

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of energy. But in the early 21st century, it was realized that most of the versions of reality described by string theory's equations cannot match up with observations of our own universe.

Stranger Things in the Universe

After years of painstaking development, too many sleepless nights, and the seemingly never-ending slog that is the careful scrutinization of data, cosmologists this spring finally made their announcement. Nautilus Members enjoy an ad-free experience. Log in or Join now . Dark energy—the mysterious force that is causing our universe to accelerate—may be evolving with time. The data could expose a crack in the standard model of the cosmos. A smal…

String theory has long been touted as physicists’ best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of energy. But in the early 21st century, it was realized that most of the versions of reality described by string theory’s equations cannot match up with observations of our own universe. In particular, conventional string theory’s predictions are inc…
