Using a specialized design approach, scientists create acoustic waves that behave as twisted, ultrasonic motors capable of rotating particles in space.
Results for "dark matter"
Dark energy telescope reveals early look at almost two million cosmic objects
Galaxies, quasars, and stars… oh my! Dark Energy Spectroscopic Instrument (DESI) first data is a small fraction of the huge cosmic survey it will conduct.
Modified theory of gravity eliminates the need for dark energy
Many physicists are still skeptical that dark energy can fully explain gravity, and are therefore exploring alternative theories.
String theory may offer an alternative to dark energy
A new study evaluates gravity using string theory, a promising candidate for describing particle interactions at their most fundamental level.
Could black holes be dark energy?
Astronomers looking at how black holes grow over time may have found the answer to one of the biggest problems in cosmology.
Explaining the Universe’s accelerated expansion without dark energy
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
Cosmic bursts unveil universe’s missing matter
Bright bursts of radio waves help astronomers locate a type of matter that researchers have been searching for for the past 30 years.
CERN scientists search for new physics in unusual energy patterns linked to hidden particles
Researchers at CERN’s Large Hadron Collider explore subtle energy signals to search for new physics beyond the Standard Model.
Hollow planets could help find primordial black holes
Small primordial black holes could have consumed the interiors of planets or asteroids, leaving their outer shells intact.
Black hole images deliver a deathblow to alternative theory of gravity
Images of the supermassive black holes wouldn’t have been possible if mimetic gravity was the right recipe for gravity.
