Researchers at the University of Waterloo say a new “quadratic quantum gravity” framework could explain the universe’s rapid early expansion without adding extra ingredients to Einstein’s theory by hand。
The idea is especially notable because it makes testable predictions, including a minimum level of primordial gravitational waves that future experiments may be able to detect。
“Even though this model deals with incredibly high energies, it leads to clear predictions that today’s experiments can actually look for,” said Dr。
Niayesh Afshordi, professor of physics and astronomy at the University of Waterloo and Perimeter Institute (PI)。
“量子引力和真实数据之间的直接联系是罕见且令人兴奋的。
Their model also predicts a minimum amount of primordial gravitational waves, which are tiny ripples in spacetime geometry created in the first moments after the Big Bang。
