Physicists discover a new way to solve the strange mystery of dark energy

Physicists have proposed a new explanation for dark energy. It can shed insights into the interdependence between quantum field theory and general relativity theory, as two perspectives of the universe and its elements. What is behind dark energy – and what links it to the cosmological constant introduced by Albert Einstein? Two physicists from the … Read more

Why more physicists are beginning to think that space and time are “illusions”

Last December, the Nobel Prize in Physics was awarded for the experimental confirmation of a quantum phenomenon known for more than 80 years: entanglement. As conceived by Albert Einstein and his collaborators in 1935, quantum objects can be mysteriously related even if they are separated by great distances. But as bizarre as the phenomenon sounds, … Read more

Quantum physicists determine how to control two quantum light sources instead of one

Researchers can now control two quantum light sources instead of just one. As … Read more

Physicists break the record for firing lasers in their university lane: ScienceAlert

Physicists have just set a new record by confining a self-focusing laser pulse to a cage of air, along a 45-meter (148-foot) long university corridor. With previous results well below a metre, this latest experiment led by physicist Howard Melchberg of the University of Maryland (UMD) breaks new ground for trapping light in channels known … Read more

Physicists have used entanglement to “extend” the uncertainty principle, improving quantum measurements

Nearly a century ago, German physicist Werner Heisenberg realized that the laws of quantum mechanics place some fundamental limitations on how accurately certain properties of microscopic objects can be measured. However, the laws of quantum mechanics can also offer ways to make measurements more precise than would otherwise be possible. In new research published in … Read more

Physicists have found that organelles grow in random bursts

Research from Washington University in St. Louis indicates that the organelles in the eukaryotic cell grow in random batches from a finite set of building blocks. Credit: Shutterstock Eukaryotic cells — the ones that make up most forms of life as we know it, including all animals, plants, and fungi — are highly organized organisms. … Read more
