In a blow to science fiction writers and daydreamers all over, it appears that the hopes of building a time machine may be dashed once and for all, reports the Los Angeles Times (LA Times) and other media outlets. Physicists at the Hong Kong University of Technology and Science have just proved that no machine will ever allow a person to travel through time because time travel is flat-out impossible and beyond the limits of the physical laws of the universe. Until now, it was thought that...

Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it? An international team of researchers, led by University of Toronto physicist Aephraim Steinberg of the Centre for Quantum Information and Quantum Control, have found a way to do just...

Bridging the classical/quantum divide Dartmouth researchers have discovered a potentially important piece of the quantum/classical puzzle "“ learning how the rules of physics in the quantum world (think smaller than microscopic) change when applied to the classical world (think every day items, like cars and trees). In a study published in the July 1 issue of the journal Nature, Associate Professor of Physics and Astronomy Alex Rimberg and his colleagues describe one example of the...

Thinking of the past or future causes us to sway backward or forward Although we can't technically travel through time (yet), when we think of the past or the future we engage in a sort of mental time travel. This uniquely human ability to psychologically travel through time arguably sets us apart from other species. Researchers have recently looked at how mental time travel is represented in the sensorimotor systems that regulate human movement. It turns out our perceptions of space and time...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...
