Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest scale imaginable according to known physics. At this limit, the Planck length, ...

If you divide the matter in the Universe into smaller and smaller constituents, you'll eventually reach a limit when you hit a fundamental, indivisible particle. All macroscopic objects can be divided ...

A bunch of the talks I went to last week at DAMOP were about searching for extremely tiny effects (I wrote about some of them, but there were a bunch more). Some of these were looking for real ...

Cosmic collider: could an advanced civilization harness a black hole Has an advanced alien civilization built a black-hole-powered particle accelerator to study physics at “Planck-scale” energies? And ...

While various studies have hinted at the existence of dark matter, its nature, composition and underlying physics remain poorly understood. In recent years, physicists have been theorizing about and ...

Scientists studying radiation from a distant gamma-ray burst have found that the speed of light does not vary with wavelength down to distance scales below that of the Planck length. They say that ...
