More evidence of sound waves carrying mass

A trio of researchers at Columbia University has found more evidence showing that sound waves carry mass. In their paper published in the journal Physical Review Letters, Angelo Esposito, Rafael Krichevsky and Alberto Nicolis ...

A high-precision test bench for LISA technology

For the first time, it has been possible to test laser measurement technology for LISA in laboratories almost under mission conditions. A team of researchers led by the Max Planck Institute for Gravitational Physics (Albert ...

Gravitational waves will settle cosmic conundrum

Measurements of gravitational waves from approximately 50 binary neutron stars over the next decade will definitively resolve an intense debate about how quickly our universe is expanding, according to findings from an international ...

Discovering new particles using black holes

Some theories that go beyond the Standard Model of particle physics predict the existence of new ultralight particles, with masses far below the lightest known particles in nature. These particles have such very weak interactions ...
