Physicists observe gravitational effect on a falling quantum object for the first time

Researchers measured gravitational effects in falling quantum particles, according to ScienceDaily.

The short version

  • An international team observed a long-predicted gravitational effect in a falling quantum object for the first time.[ScienceDaily]
  • The experiment utilized ultracold rubidium atoms cooled close to absolute zero and was published in Science Advances.[ScienceDaily]
  • The findings do not provide a unified theory of quantum mechanics and gravity, nor do they prove gravity is quantum.[ScienceDaily]

Key facts

  • Researchers directly observed a gravitational effect in a falling quantum object for the first time.[ScienceDaily]
  • The research was published on September 2 in Science Advances.[ScienceDaily]
  • The experiment used rubidium atoms cooled to temperatures just above absolute zero.[ScienceDaily]

What remains uncertain

  • The findings do not provide a unified theory of quantum mechanics and gravity, nor do they demonstrate that gravity itself is quantum.[ScienceDaily]
