Microscopic wormholes may be driving the accelerated expansion of the universe, scientists say. These tiny wormholes are constantly being born from the vacuum of space due to subtle quantum effects.
If confirmed through experiments and observations, the wormholes could become a valuable source of information on quantum gravity — a theoretical unification of the fundamental forces of the universe, often considered to be the Holy Grail of theoretical physics.
Numerous astronomical observations show that our universe is expanding at an ever-increasing rate. However, Einstein’s general theory of relativity states that if the universe contains only the species of particles and radiation we know, such behavior of the fabric of space is impossible.
