Quadratic Gravity Theory Reshapes Quantum View of Big Bang

New Research Says the Big Bang May Be Linked to a "Deeper Theory of Gravity," Challenging Past Ideas

Researchers say a new theory tackling the Big Bang could reshape how physicists think about the earliest moments of cosmic history. A team at the University of Waterloo and the Perimeter Institute for Theoretical Physics has taken a different approach to exploring the origins of the universe from past efforts, with a new theory that points to a rapid expansion that occurred after the Big Bang, which could have arisen naturally from a deeper theo…

Quadratic gravity theory reshapes quantum view of Big Bang

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe's rapid early expansion could have arisen naturally from a deeper, more complete theory of quantum gravity. The paper, "Ultraviolet completion of the Big Bang in quadratic gravity," appears in Physical Review Letters.

Revolutionary Theory Transforms Quantum Perspective on the Big Bang

In an extraordinary leap toward demystifying the origins of our cosmos, researchers at the University of Waterloo and the Perimeter Institute for Theoretical Physics have introduced a groundbreaking framework that promises to transform our understanding of the Big Bang. Steering clear of the conventional reliance on Einstein’s General Relativity supplemented by arbitrary external components, this […]
