How logic alone may prove that time doesn't exist

Modern physics suggests time may be an illusion. Einstein's theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously—with no special ...

Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...

Evidence of a new subatomic particle observed

The BESIII collaboration have reported the observation of an anomalous line shape around ppbar mass threshold in the J/ψ→γ3(π+π-) decay, which indicates the existence of a ppbar bound state. The paper was published ...

Searching for new asymmetry between matter and antimatter

Once a particle of matter, always a particle of matter. Or not. Thanks to a quirk of quantum physics, four known particles made up of two different quarks—such as the electrically neutral D meson composed of a charm quark ...

Designing a cost-effective X-ray free electron lasers facility

Many advances in structural science since the 1970s were made by probing materials with synchrotron radiation: that is, high energy X-rays generated through accelerating high-energy electrons. The latest generation of such ...
