But the technology could also, theoretically, be used to develop placid super-soldiers.

The hunt for gravitational waves is back on. After a series of upgrades, the National Science Foundation’s Laser Interferometer Gravitational-Wave Observatory (LIGO) will resume its search for ripples in space and time on Monday, April 1.
LIGO is famous for making the first direct detection of gravitational waves in 2015, for which the observatory’s founders were awarded the Nobel Prize. The observatory was able to detect gravity waves generated by two colliding black holes which were located 1.3 billion light-years away from Earth, and since then has observed nine more black hole mergers and one collision of two neutron stars.
Gravitational waves are ripples in the fabric of spacetime, caused by massive bodies which bend it like a bowling ball placed on a rubber sheet. They were predicted by Einstein as part of his general theory of relativity in 1916, but it took nearly a century for physicists to observe them because the effects are so small. Since these waves have been detected, they can be used to investigate cosmic objects as an alternative to light-based telescopes.

Physicists have measured the sound of ‘nothingness’ at room temperature — an important step in our future ability to listen in to the Universe.
You can think of it a little like this — we’ve now been able to measure the way some of the ubiquitous ‘background noise’ of space interacts with our equipment, which will hopefully help us tune it out going forward.
After all, the entire Universe is crackling with the static of quantum physics, and in order to be able to pick up the faint echoes of distant astronomical giants — such as the gravitational waves rippling off a black hole merger, for example — we need to be able to tune out the quantum static.

Science fiction met space fact this week in the Seattle area when the cast of “The Expanse,” the science-fiction jewel in Amazon’s streaming-video crown, got a look at Blue Origin’s spaceship.
Amazon CEO Jeff Bezos is the common denominator in the meetup: He personally engineered the sci-fi series’ shift from SyFy to Prime Video, and announced it onstage at a space conference last May while I was sitting beside him. Bezos is also the founder of Blue Origin, the space venture that is testing its New Shepard suborbital spaceship and gearing up to build its orbital-class New Glenn rocket.
During last May’s sit-down with Bezos, I joked that cast of “The Expanse” might want to take a ride on New Shepard, just to get some real-life experience behind their portrayal of space travel. And Bezos played along.
