Creates the fastest artificial object on the planet

Scientists have set a record for the fastest rotating object made by humans. A tiny device can make more than 300 billion revolutions per minute and move 500,000 times faster than a dental drill. According to newsweek.com, a team from Purdue University in France has used a powerful laser to accelerate a microscopic object floating in a vacuum to set a world record.

Purdue University specialists have developed a unique method to create the fastest object on the planet.

What is the fastest object on the planet?

The fastest rotating object on earth was created in the walls of a French laboratory where scientists were able to use light to levitate a microparticle in a vacuum. This became possible because photons – the smallest particles of light – have hardly any measurable effects on any object with which they are in contact in one way or another. It is known that the force of such an interaction is the pressure of light radiation, which in this case is a million times weaker than gravity – one of the four fundamental forces in the universe.

Photons of light can accelerate particles to incredible speeds

When Johannes Kepler first noticed in 1600 that the tails of the comets always point in the opposite direction from the sun, the scientist could not even imagine that his discovery could one day help create the fastest object that mankind ever had has observed. For example, Tongtsan Lee, professor of electrical and computer engineering at Purdue University, argues that the new method of giving speed to a small object is based on the same principles that Kepler identified when studying comets. In addition, experts used the properties considered by Kepler when working with concentrated lasers to turn nanoparticles. According to the scientists, the resulting nanoparticle is not only the fastest, but also the most sensitive of all known torque detectors.

Despite the fact that the pressure of light radiation is an extremely weak force, the prospect of using it can reassure any science fiction fan. The technology is already being used to test new methods for moving spaceships, including the LightSail-2 device: It is known that the sun sail project developed by the US Planetary Society with the support of SpaceX and Ilon Mask is moving with the help of solar photons can, the earth-like sailboats resemble with wind power. The technologies of the LightSail 2 project can become a prototype for a new generation of spacecraft that can develop incredible speeds. By the way, one of these ships will be able to reach the closest star system from Proxima Centauri in a few decades.
