Some signs of quantum gravity may be an illusion

Quantum mechanics and Einstein's theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some experiments that appear to show gravity behaving quantum mechanically may have a much more ordinary explanation.

Quantum mechanics and Einstein's theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them.

A new theoretical framework suggests that some experiments that appear to show gravity behaving quantum mechanically may have a much more ordinary explanation.

Researchers found that scenarios involving a supposed "superposition of gravity" can sometimes be described equally well as quantum particles moving through classical spacetime.
