Can Gravity Create Light?
A group of researchers have made a shocking discovery about one of the most fundamental forces in our universe. According to a new paper, which is set to publish in Physics of the Dark Universe next month, gravity may have created light in the earliest days of the universe.
According to the new paper, early gravitational waves may have been so strong that they created radiation because they shook space-time so hard. It’s an intriguing discovery that rethinks what we know about gravity as a whole, despite it being one of the most fundamental forces in existence.
The basic theory behind the belief that gravity could create light rests heavily on the forcefulness and strength of gravitational waves found in the early universe, back when the early universe formed and experienced an event that scientists call inflation.
According to this proposed event, the universe expanded greatly in a very short time, creating a sloshing mess of gravitational waves that would have collided with each other over and over again. As we know them today, these waves are extremely weak and require very strong equipment to detect them.
