The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

Researchers have devised a new way to define thermodynamic concepts in microscopic quantum systems, where conventional distinctions between heat and work begin to blur. Researchers at the University o ...

For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered ...

But in Tallulah, a charming town in Madison Parish, retirees are quietly living their best lives without checking their bank accounts every fifteen minutes or subsisting on a diet of discount ramen ...

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they ...

Researchers at the University of Stuttgart have successfully teleported quantum states between photons from two distant light sources, marking a pivotal advance toward practical quantum repeaters.

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Over geological time, information loss is the norm, not the exception. The “unitarity” principle of quantum mechanics says ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

How many times have you said, “I wish the days were longer”? Well, NASA scientists say the construction of China’s Three ...

At first glance the foxes looked unchanged but inside, the experiment was rewriting nature’s script. The team removed fear of ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...
