Why the laws of physics do not really exist

by Sankar Das Sarma The laws of physics may not be what they seem Yuichiro Chino/Getty Images Below is an excerpt from our Lost in Space-Time newsletter. Every month, we hand the keyboard over to a physicist or two to tell you great ideas from their corner of the universe. You can subscribe to Lost … Read more

Information is the frontier of the study of life

Life is really strange. From a physicist’s point of view, it looks even stranger. Life is unlike any other phenomenon in physics. Stars, electrons, and black holes are all amazing in their own way. But only life invents, and the first thing life invents is itself. Life is creative in a way There is no … Read more

Gamma ray eccentric forces explode revision of the theoretical framework

Submission of the artist. Credit: Anyu Lei and Jing Chen, Nanjing University College of Art The mysteries of the universe continue to fascinate astronomers, and with each new observation comes an opportunity to deepen–or overturn–our understanding of the cosmos. In the December 7 issue of the magazine natureAn international team of astrophysicists reports the discovery … Read more

The light paradox goes beyond the wave-particle duality

This is the third article in a series of articles exploring the birth of quantum physics. Light is a paradox. It is associated with wisdom and knowledge, with deity. The Enlightenment suggested the light of reason as a guiding path toward truth. We evolved to identify visual patterns with great accuracy—to distinguish foliage from a … Read more

Detecting dark matter using quantum computers

In a new breakthrough, scientists at the US Department of Energy’s Fermilab have found a way to detect dark matter using quantum computers. Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists don’t know much about it. They already know that it’s cold, which means that the … Read more

The threat of a common enemy may no longer unite polarized Americans, a study finds

Credit: Pixabay/CC0 Public Domain During World War II, the Americans banded together. They ate less meat and planted victory gardens. They lowered the thermostats and rationed gasoline. Republican, Democrat – it didn’t matter: Faced with a common enemy, American civilians were willing to sacrifice for American interests. That was 80 years ago, when the political … Read more

Scientists use a quantum computer to experiment with teleportation

Scientists say they have successfully used a quantum computer to “Teleportmessages between two imitative black holes. Quantum computing uses elements of quantum physics to complete processes that are too complex for conventional computers. Quantum physics is the study of matter and energy at the level of atoms or smaller. Researchers recently announced the creation of … Read more

Quantitative light color change on an integrated chip

Changing the color of single photons using an integrated phase modulator. Credit: Loncar Lab/Harvard SEAS Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they must have the same color — or frequency — and bandwidth. Changing the frequency of a photon requires changing its energy, … Read more
