If the sun's gravity could be used to create a giant telescope, people could send and receive intensely magnified signals that could allow us to call an alien civilization, some researchers propose.

Researchers announced that the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO), a huge physics experiment built to detect gravitational waves, has yet to find any. Rather than be disappointed by the null findings, physicists say the results were expected, and in fact help them narrow down possibilities for what the universe was like just after it was born.

Super-sensitive polarization detectors developed by the National Institute of Standards and Technology (NIST) and university partners will seek to measure whether the universe is forever expanding. The sensors also have civilian uses such as reducing glare in next-generation terahertz imaging systems that can see through the thick metal of shipping containers to detect hidden contraband.

The JASON Defense Advisory Group has issued a report assessing whether high-frequency gravitational waves could pose a threat to US security, be used to image the centre of the Earth, or be used for telecommunications.

An elite defense science advisory panel dismissed claims that high frequency gravitational waves (HFGW) could pose any kind of national security threat by being used for faster-than-light vehicle propulsion, enhancing GPS signals, or even long-range imaging.

A $205 million upgrade will allow a laser-wielding observatory to monitor tens of thousands of galaxies for mysterious gravitational waves. Leading investigators are confident that the Advanced LIGO (Laser Interferometer Gravitational-wave Observatories) Project will be able for the first time to detect gravitational waves from neutron stars and black holes, as predicted by Einstein's theory of general relativity.

Scientists searching for waves of gravitational energy that stretch space and time will soon be seeking the public's help in analysing their data.

Michio Kaku argues that new space probes will provide critical new information on parallel universes, cosmology, and wormholes that humanity will need to survive in the long-term.

India has begun an extensive scientific campaign to study gravity waves in the atmosphere.
