Scientists at the American University of Bordeaux have invented the fastest object in the universe, which is designed to measure the frictional force that arises from quantum fluctuations.
Science Alert Magazine reports that this object is constituted of atoms of silica nanoparticles (silicon dioxide), in the shape of dumbbells flying in the vacuum, of a (150) nanometers diameter and around a billion rounds per second.
This system is so sensitive that it is possible to measure quantum fluctuations.
Lasers are used to fly and spin these particles, one of which generates pulses of polarized light.
As a comparison, the dental drill rotates at a speed of (500) thousand rounds per minute, while the pulsar with the record rotational speed – the fastest known natural organism rotates (707) rounds per second or (42420) rounds per minute.
The researchers were able to increase the speed of these particles to (300) billion rounds per minute.
This new experiment is an update of the Cavendish experiment, which resulted in coming up with gravitational constant value in (1793), when the scientist (Henry Cavendish) used two balls of lead of different masses installed at the ends of a shaft of (1.8) meters length hung to a wire.
The two balls were of proximate weights, which allowed the calculation of (the gravitational constant) based on the measurement of the twisting of the wire.
Nanoparticles, which rotate very quickly, are sensitive to quantum fluctuations in the vacuum, and are able to convert them into radiation.
This in turn affects the measurement of particles’ rotation.
