Quantum Spacetime Measured in an Major Step to Understanding the Fabric
of Reality

Physicists at Fermilab Measured Spacetime on the Planck Scale

The Debrief, 19 Feb 2021

Scientists with Fermilab recently announced the successful measurement
of quantum spacetime at the smallest imaginable scale in known physics,
known as the Planck length.

According to quantum mechanics, everything is continuously fluctuating
on microscopic scales. However, when measuring quantum matter on the
Planck-scale, scientists discovered that quantum spacetime is perfectly
still in the smallest region possible.

While considerable unknowns remain, gaining a better understanding of
quantum spacetime's bizarre world could be a significant step to
understanding the very fabric of reality and why things happen at
definite times and places. ...

Using an ultra-sensitive laser interferometer, the Holometer can detect
holographic fluctuations in quantum spacetime. As laser light passes
through an arrangement of mirrors in the Holometer, the mirrors can
show minute jitters of matter, or quantum-geometrical fluctuations.
Physicists call this property of spacetime "holographic" noise. ...

Recently completing final experiments with the reconfigured Holometer,
the Fermilab team of scientists once again found quantum spacetime at
the Planck scale is perfectly still. "Our final result is again no
jitters, which can be interpreted as no Planck-scale twists, of a
certain kind, in the fabric of spacetime. It seems spacetime at the
Planck scale is very quiet indeed," said Dr. Hogan in a statement
provided by Fermilab. Results of the study were published in the
journal General Relativity and Quantum Cosmology. ...
