What if the dark energy, which according to astrophysicists represents almost 75% of the entire universe did not exist? Is the proposal that launch the American Mathematical Joel Smoller and Blake Temple in the latest issue of the journal PNAS.
few years ago astronomers thought that after the big bang of the Big Bang, the universe must be slowing. However, the study of distant supernovae revealed that the universe is expanding at an increasing rate. To explain this mysterious acceleration introduced the concept of dark energy.
Astrophysicists have worked with this scenario during the last decade, but this could be about to change. Smoller and Temple have just developed a model based on Einstein's equations to explain the anomalous acceleration of the universe without resorting to dark energy or cosmological constant (initially introduced by Einstein in his field equations of general relativity). Under the new theory, the universe would spread in waves, which would explain the acceleration of the galaxies.
