Scientists State The Laws of Physics May Be Changing

Image by GettyHowever, we would bet most people do not think that line applies to the actual rules of the universe itself. As it turns out, however, researchers at Microsoft, scientists at Brown University, and one professional who consulted for Disney's "Wrinkle in Time" believe the laws of physics may actually be slowly changing, complicating...

Robotic Motion In Curved Space Defies Common Laws of Physics

Until currently, physicists thought this to be a constant, following the law of...

SU(N) Matter Is About Three Billion Times Colder Than Deep Space

An artist’s conception of the complex magnetic correlations physicists have observed with a groundbreaking quantum simulator at Kyoto University that uses ytterbium atoms about 3 billion times colder than deep space. Different colors represent the six possible spin states of each atom. The simulator uses up to 300,000 atoms, allowing physicists to directly observe...

Building a “Quantum Heat Pump” To Search For Elusive Dark Matter

Scientists have developed a heat pump that uses light particles on a quantum range. Scientists can currently measure radio frequency signals closer to the quantum limit. Professionals say this technique works in searching for dark matter, a component of the universe whose existence is discernible primarily by its gravitational attraction. 30.1 percent of the...

New Proof That Water Separates Into Two Different Liquids At Low Temperatures

Credit: CC0 Public DomainA new kind of "phase change" in water was first recommended 30 years ago in a research study by scientists from Boston University. Because the shift has been predicted to happen at supercooled problems, however, confirming its presence has been challenging. That is because, at these low temperatures, water really does...

Physicists Make Significant Gains In Race For Room-Temperature Superconductivity

A team of physicists from UNLV's Nevada Extreme Conditions Lab (NEXCL) used a diamond anvil cell, a research device similar to the one pictured, in their research to lower the pressure needed to observe a material capable of room-temperature superconductivity.

The design might allow the construction of an ultrafast laser up to 1,000...

Japan’s Fugaku Supercomputer Powers Up Drug Discovery, Storm Forecasts

TOKYO-- Discovering brand-new drugs and also predicting severe weather is one of the tasks the Japanese-built Fugaku, 1 of the world's rapid supercomputer, has taken on as its applications broaden.Fugaku will certainly be at the center of a two-year experimental study research focused on a pharmaceutical development platform. The government-sponsored project, posted in July,...

Scientist Says That Dark Matter May Be Information Itself

Info DumpThere is no shortage of debate regarding the nature of the dark matter, a mysterious substance that many physicists believe makes up a large proportion of the total mass of the universe, despite never having observed it directly.Currently, a physicist from the UK called Melvin Vopson is raising a startling possibility: that dark...

Three Papers Highlight the Results Of Record 1.3 Megajoule Yield Experiment

On the one-year anniversary of achieving a yield of more than 1.3 megajoules at LLNL’s National Ignition Facility, the scientific results of this record experiment have been published in three peer-reviewed papers: one in Physical Review Letters and two in Physical Review E. This stylized image shows a cryogenic target used for these record-setting inertial fusion experiments. Credit:...
