Yes, black holes exist in gravitational theories with unbounded speeds of propagation
Lorentz invariance (LI) is a cornerstone of modern physics, and strongly supported by observations.
Engineering discovery brings invisibility closer to reality
Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered ...
Mathematical scientist suggests possible test for existence of axions
Solving a physics mystery: Those 'solitons' are really vortex rings
(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying ...
Team finds 'tipping point' between quantum and classical worlds
If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons - the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's ...
'Photon glue' enables a new quantum mechanical state
(Phys.org) —Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials.
Universe may face a darker future
New research offers a novel insight into the nature of dark matter and dark energy and what the future of our Universe might be.
Atoms queue up for quantum computer networks
In order to develop future quantum computer networks, it is necessary to hold a known number of atoms and read them without them disappearing. To do this, researchers from the Niels Bohr Institute have developed ...
Researchers build acoustic tractor beam
Physicists investigate onset of effective mass
Biology meets geometry: Describing geometry of common cellular structure
Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ...
Researchers make magnetic graphene
Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic ...
Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years
Researchers design first battery-powered invisibility cloak
Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.
