Evidence of Gravitons

A research team led by Chinese scientists has provided the first experimental evidence hinting at the existence of gravitons, theoretical particles believed to mediate the force of gravity, according to the South China Morning Post (SCMP).

This discovery marks a significant step towards bridging the gap between quantum mechanics and general relativity, two pillars of modern physics that have remained largely incompatible.

The research, carried out by a collaboration between scientists from Nanjing University in eastern China, the United States, and Germany, involved placing a thin layer of semiconductor under extreme conditions. 

By cooling the semiconductor to near absolute zero and applying a magnetic field 100,000 times stronger than the Earth’s, the team managed to excite the semiconductor’s electrons to move in unison. This collective motion caused the electrons to spin in a manner consistent with predictions about gravitons, despite not confirming the particle’s direct existence.

“Our work has shown the first experimental substantiation of gravitons in condensed matter since the elusive particle was conceptualized in the 1930s,” Du Lingjie, the study’s lead author from Nanjing University, told state news agency Xinhua, as reported by SCMP.  READ MORE...
