Forget the Big Bang: Gravitational waves may have really created the Universe

A team of scientists has proposed a groundbreaking new theory on the Universe's origins, offering a fresh, radical take on the Big Bang's early moments. Unlike the widely accepted inflationary model, which involves speculative assumptions, the new model starts with the established concept of De Sitter space, aligning with dark energy observations. The scientists believe gravitational waves—ripples in space-time—were the key to seeding the formation of galaxies and cosmic structure, eliminating the need for unknown elements.
