Do 'bouncing universes' have a beginning?

Aug 11, 2022 (SPX)

Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end - only eternal cycles of growing and shrinking that exte...

First stars and black holes

Aug 11, 2022 (SPX)

Did primordial black holes help or hinder formation of the universe's first stars, eventually born about 100 million years later? Supercomputer simulations help...

UK scientists have created an 'eternal engine' to keep the next generation of atomic clock ticking.

Aug 11, 2022 (SPX)

Now, research undertaken at the University of Sussex, and continued at Loughborough University, has solved a major stumbling block in the development of these p...

No trace of dark matter halos

Aug 09, 2022 (SPX)

Dwarf galaxies are small, faint galaxies that can usually be found in galaxy clusters or near larger galaxies. Because of this, they might be affected by the gr...

A molecule of light and matter

Sneaky discovery sheds light on star death, black holes and gravity waves

Jul 26, 2022 (The Conversation)

Albert Einstein first published his book explaining the theory of general relativity - which postulated black holes - in 1922. One hundred years later, astronom...

Unravel the mystery of the quasar's anisotropic effects on surrounding gas

Jul 26, 2022 (SPX)

Because luminous nuclei of distant galaxies (quasars) emit strong ultraviolet radiation, they ionize** hydrogen gas (intergalactic gas***) around them. If the q...

Photonic spin hall effect: Fundamentals and emergent applications

Jul 26, 2022 (SPX)

It can be regarded as an analogue of the spin Hall effect in electronic systems: the right-handed and left-handed circular polarization components of light play...

Scientists capture first-ever view of a hidden quantum phase in a 2D crystal

Jul 25, 2022 (SPX)

AI-assisted analysis of three-dimensional galaxy distribution in our Universe

Jul 22, 2022 (SPX)

When the biggest galaxy survey to date in the world, the Sloan Digital Sky Survey (SDSS), created a three-dimensional map of the universe via the observed distr...

Measuring the Universe with Star-Shattering Explosions

Jul 22, 2022 (SPX)

With no landmarks in space, it is very difficult to get a sense of depth. One technique astronomers use is to look for "standard candles," objects or events whe...

Novel way to 'see' the first stars through the fog of the early Universe

Jul 22, 2022 (SPX)

The researchers, led by the University of Cambridge, have developed a methodology that will allow them to observe and study the first stars through the clouds o...

Physicists harness quantum time reversal to measure vibrating atoms

Jul 15, 2022 (SPX)

A major hurdle in the path toward better quantum measurements is noise from the classical world, which can easily overwhelm subtle atomic vibrations, making any...

Physicist defends validity of Stokes-Einstein equation in living systems

Jul 15, 2022 (SPX)

Working with proteins in live bacteria, Yong Wang, assistant professor in the Fulbright College of Arts and Sciences, tested the 117-year-old equation, which pr...

A new spin on nuclear magnetic moments

Jul 15, 2022 (SPX)

These nuclei do not exist in nature, and once created, their lifetimes can be as short as a fraction of a second, so the team artificially created the nuclei us...
