_Researchers have proposed a new model that suggests the early universe's rapid expansion, known as inflation, may not have been powered by a new entity called the inflaton. Instead, they propose that the quantum foam of space-time, which is constantly shaking up space-time at submicroscopic scales, could have generated the necessary gravitational waves to create the seeds of large-scale structures in the universe. This model relies on the cosmological constant, a measure of the universe's expansion rate, and assumes that the quantum foam's fluctuations can create the right kind of deformations in space-time to form these structures._
