Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
Could classical theory be just as weird as quantum theory?
Is the universe a hologram?
Describing the universe requires fewer dimensions than we might think. New calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.
Throwing light on a mysterious human 'superpower'
Most people, at some point in their lives, have dreamt of being able to fly like Superman or develop superhuman strength like the Hulk. But very few know that we human beings have a "superpower" of our own, ...
Physicists offer a solution to the puzzle of the origin of matter in the universe
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, ...
Photon 'afterglow' could transmit information without transmitting energy
Loophole in theory offers insight into the 'lithium problem'
Physicists propose method to measure variations in the speed of light
Higgs particle can disintegrate into particles of dark matter, according to new model
The 'Standard Model' of particle physics successfully describes the smallest constituents of matter. But the model has its limitations – it does not explain the dark matter of the universe. Christoffer ...
New way to calculate how long it would take to fall through a hole in the Earth
Unlikely hydrogen bond discovered
As with magnets and alternating current, positively charged molecules never aim for one another. Indeed, similarly charged poles are repelled. Nevertheless, a team from the University of Copenhagen's Department ...
A pinch of baking soda for better vision?
Bicarbonate (baking soda) makes sparkling water sparkle, causes bread to rise, absorbs odors and can be used for cleaning all sorts of stuff, including your teeth. In the body, it plays essential roles in ...
When temperature goes quantum
A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential ...
