Quantum sensors could end submarine stealth by detecting the faintest magnetic or gravitational ripples deep underwater. As nations race to deploy them on drones and ships, the future of naval warfare may depend on who masters this new undersea detection power first.


How quantum sensors could make submarines almost impossible to hide

While the concept of warp drives may seem like something out of science fiction, recent research suggested that these hypothetical faster-than-light engines could produce detectable gravitational wave signals and detect alien civilisations.

Warp drives may reveal alien civilisations by sending gravitational waves through universe

The Indian government gave a go-ahead to Rs 2,600-crore project on Thursday for setting up a Laser Interferometer Gravitational Wave Observatory-India (LIGO-India) in the Aundha area of Hingol district in Maharashtra.

In landmark move, India gives nod to LIGO observatory in Maharashtra to study gravitational waves

The waves, caused by the collision of two neutron stars some 130 million years ago, were first detected in August by the Laser Interferometer Gravitational-Wave Observatories

Scientists detect light from gravitational wave source
