![]() ![]() This workshop will discuss various theoretical and experimental challenges to conceive the QGEM protocol in a lab that will require an unprecedented level of accuracy in witnessing the quantum nature of one of nature’s weakest interactions. This prescription for witnessing entanglement certifies gravity as a coherent quantum mediator through simple correlation measurements between two spins: one embedded in each test mass known as a QGEM (quantum gravity induced entanglement of masses) protocol. Despite the purported weakness of gravity, the phase evolution induced by the gravitational interaction of two-micron size test masses in adjacent matter-wave interferometers can detectably entangle them via the exchange of graviton mediation even when they are placed far enough apart to keep Casimir-Polder forces at bay. Along this line, a primary question is whether gravity is a quantum entity subject to quantum mechanical rules. Plus: Extreme Gs in a centrifuge – Simulating gravity on other planets, what it’s like to live in space with astronaut Chris Hadfield, cooking in space with ESA astronaut Samantha Cristoforetti, videos about zero-g, and more videos about spinning.Understanding gravity in the framework of quantum mechanics is one of the significant challenges in modern physics.

For all my mind could tell, my limbs were not there…”Īstronauts typically have an allocated exercise period of two hours a day in space to counteract these effects… Despite exercise, it still takes months of rehabilitation to adjust on Earth after a typical six-month space mission. “The first night in space when I was drifting off to sleep,” one Apollo astronaut said in a NASA interview, “I suddenly realized that I had lost track of … my arms and legs. Bones and muscles weaken, and other changes also take place within the body… Astronauts’ sense of up and down gets confused, NASA said, because the vestibular system no longer can figure out where the ground and the ceiling are…Ĭrewmembers also experience a disruption in their proprioceptive system, which tells where arms, legs and other parts of the body are oriented relative to each other.
