A new study proposes that gravitational waves, rather than the traditional inflation theory, could explain the universe's origins, offering a simpler and more verifiable model based on Einstein's general relativity and De Sitter space, potentially reshaping our understanding of the early universe.
A new study proposes an alternative to the inflation theory of the universe's origins, suggesting that gravitational waves and the De Sitter space model could explain the universe's formation and evolution without requiring a rapid expansion immediately after the Big Bang.

Researchers from Kyoto University are exploring 'de Sitter space' to explain gravity in the expanding early universe by invoking a higher dimension. They have developed a method to compute correlation functions among fluctuations on the expanding universe by making use of holography. The team's calculations only considered a three-dimensional universe as a test case, but the analysis may easily be extended to a four-dimensional universe, allowing for the extraction of information from our real world. The approach possibly contributes to validating superstring theory and allows for practical calculations about the subtle changes that rippled across the fabric of our early universe.
