Gravitational wave scientists from The University of Western Australia have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test fundamental limits of general relativity.

Research Associate from UWA's Centre of Excellence for Gravitational Wave Discovery (OzGrav-UWA) Dr. Aaron Jones said UWA coordinated a global collaboration of gravitational wave, metasurface and photonics experts to pioneer a new method to measure structures of light called "eigenmodes."

The proof-of-concept setup the team developed was over one thousand times more sensitive than the original apparatus developed by telecoms scientists and the researchers will now look to translate this work into gravitational wave detectors.

OzGrav-UWA Chief Investigator Associate Professor Chunnong Zhao said the development is another step forward in detecting and analyzing the information carried by gravitational waves, allowing us to observe the universe in new ways.

"Solving the mode sensing problem in future gravitational wave detectors is essential if we are to understand the insides of neutron stars and further our observation of the universe in a way never before possible,"

Wow. Amplitude modulated light for fiber optics

You can solve for these using the cross section of maxwells silver hammer to determine the capability of the coupled flexural/torsional oscillations as well as the suitability of the first lateral eigenmode, you can also calculate in-plane forces from torsional and lateral frequency-shift data and analyze the origin of the forces regarding friction or shear

Not so sure about blac chyna holes though

Are we talkin’ QPSK or DSPK?

[algore]

Not sure what they are trying to pitch.

I think it is a Coherent PM-QPSK

We’ve been doing this is the US for years. Its called LIGO: Laser Interferometer Gravitational Wave Observatory. There’s one observatory in Livingston LA and an identical one in Hanford WA. The facilities operate in synchronized simultaneity. The scientists won a Nobel Prize for physics not long ago by being able to correctly predict the collision of two Black Holes hundreds of thousands of light years away by measuring miniscule changes in gravitational waves and in doing so, proving one of Einstein’s early prediction.
