Breakthrough in the nonlinear generation of primordial gravitational waves

It has always been hard to measure gravitational waves especially in the beginning of the universe. We have just recently discovered a way to do it. This new breakthrough from China and Japan have discovered old gravitational waves in high energy physics when the universe was born. It was found by a phenomenon and then it was probed by the gravitational wave detectors that we have recently been using. This will give us a lot of information about the infancy of the universe.

Key Takeaways:

• It has been very hard to measure gravity waves, but we have discovered a new way.
• The teams that created and found this are from all over the world.
• They are hoping to get more answers to the birth and beginning of the universe.

“In a Physics Review Letters paper published on Dec 15th, an international research team, led by Cai Yifu, professor of the University of Science and Technology of China, and his collaborators discovered the hypothetical possibility of resonantly generated primordial gravitational waves within high-energy physics when the universe was in its infancy.”
