ON A human scale, an atom is inconceivably small. But size is relative. On the Planck scale—the smallest that physical theory recognises—atoms are huge. At this scale, named after Max Planck, the ...

Quantum gravity theory is untested experimentally. Could it be tested with tabletop experiments? While the common feeling is pessimistic, a detailed inquiry shows it possible to sidestep the onerous ...

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, ...

Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. Now scientists have proposed a new quantum experiment ...

The economy has been sputtering for years; it sure could use a boost. Planck-scale physics is the coming thing in basic science. How big a boost could the economy get from Planck-scale physics? A new ...

(Phys.org) —While the natural world is replete with compounds that form the basis of many disease-fighting pharmaceuticals, it is also the case that humans and other mammals produce their own ...

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: ...

(Phys.org) —Two astrophysics, Carlo Rovelli and Francesca Vidotto, have uploaded a paper to the preprint server arXiv in which they suggest that a structure known as a Planck star exists at the center ...
