Astrophysicists duo propose Planck star as core of black holes
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Looking at quantum gravity in a mirror
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. At this scale, new phenomena could arise. However, the Planck-scale ...
Holometer experiment to test if the universe is a hologram
Is Everything Made of Mini Black Holes?
Physicist proposes simple experiment to detect foam-like structure of the universe
Smooth or grainy? New paper reviews research on the grain of space-time
Smooth" or grainy? Is space-time continuous or is it made up of very fine (10-35 metres on the "Planck scale") but discrete grains, if we look at it very close up ? If the latter were true, scientists think, ...
