Significant advances in exploring QG-motivated phenomenology 3 have been achieved in the past decade. In some cases, it was possible to establish bounds on QG effects at the Planck scale. Among the ...

(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 ...

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 ...

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 ...

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, ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...

(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 ...
