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 ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

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 ...

No matter how much evidence there is supporting their existence, black holes remain firmly in the realm of theoretical physics. Because of their properties—their structure, the fact that they emit no ...

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, ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The greatest scientific legacy that Albert Einstein left us is this: ...
