Voltage-Driven Liquid Metal Forms Snowflake-Like Fractals

A team of scientists at North Carolina State University has demonstrated that a gallium-based liquid metal alloy forms snowflake-like fractal patterns when electrochemically oxidized. The results appear in the journal Physical Review Letters. Gallium indium forms fractal patterns with the application of low voltage. Image credit: North Carolina State University. …

New Theory Explains Why Our Universe is Three-Dimensional

According to a new theory proposed by University of Edinburgh Professor Arjun Berera and colleagues, shortly after the Universe came into existence it was filled with ‘knots’ formed from flexible strands of energy called flux tubes that link elementary particles together. This is a graphic depicting formation of flux tube …

Scientists Detect Gravitational Waves from Colliding Neutron Stars

The LIGO Scientific Collaboration, Virgo Collaboration, and their partners have directly detected gravitational waves — ripples in space and time — from a pair of inspiraling neutron stars. Named GW170817, the event was not only ‘heard’ in gravitational waves but also seen in light by dozens of space- and ground-based …

Discovery of Gravitational Waves Wins 3 US Scientists Nobel Prize

In 1916, the famed theoretical physicist Albert Einstein postulated certain events in the universe would produce gravitational waves. The detection of such waves would be even more confirmation of general relativity, but Einstein suspected the waves would be too faint to be detected on Earth. Now, 100 years later, three …

Physicists Catch Fourth Gravitational Wave: GW170814

The LIGO Scientific Collaboration and the Virgo Collaboration report the first joint detection of gravitational waves, ripples in the fabric of space and time, first predicted by Albert Einstein more than a century ago. This is the fourth announced detection of a signal from two black holes in their final …

Scientists Design New Form of Aluminum That Floats

Aluminum is probably one of the most familiar metals in the modern world thanks to its usage in everything from smartphones to aluminum foil. Aluminum is so commonly used because it has a low melting point, works well in alloys, and is relatively light compared with its overall strength. What if …
