Or could it be evidence for an electromagnetic basis for gravity?A China-led team has detected the first experimental evidence for particles that behave like a graviton, a long-sought-after particle that gives rise to gravity, a fundamental force in our universe.
By putting a thin layer of semiconductor under extreme conditions and exciting its electrons to move in concert, researchers from eastern China’s Nanjing University, the United States and Germany found the electrons to spin in a way that is only expected to exist in gravitons.
Although the experiment did not confirm the existence of gravitons directly, it was the closest scientists had been and would open a new pathway to the search for gravitons in laboratories, the team reported in the journal Nature this week.
