Roto turned the fastest in human history

Scientists created a tiny rotor spinning at speeds of up to 60 billion rpm - the fastest artificial roto in history, and 100,000 times faster than a normal toothed drill.

The record breaking invention not only extends the boundaries of physics but can also be used to study some of the mysteries of quantum mechanics and how objects work in a vacuum.

The team said it must really face some of the basic principles of science here, like how gravity and friction work in a vacuum. Now that nano robots have been set up and functioning, some detailed research can begin.

Senior researcher Tongcang Li from Purdue University in Indiana said: 'This study has many applications, including physical science. We can study the harsh conditions that different materials can exist. "

Super gyroscopes are made up of a silica nanoparticle, shaped like dumbbells and levitated in a vacuum with a laser. The laser can be polarized in a straight line or circle, and its circle mode creates rotation.

When the laser beam is straight, the dumbbell vibrates more than rotates - meaning it can be used to measure very weak forces. Both modes of operation will be useful for future research.

The nanoparticle itself is only the size of a bacterium, about 170 nanometers wide and 320 nanometers long, so you can't see it with the naked eye. But its design looks like this:

Mr. Li said: 'People say there is nothing in the vacuum, but in physics, we know it is not really empty'.

'There are many particles that can survive for a short time and then disappear. We want to find out what's going on there, and that's why we want to create the most sensitive twisted balance . "

One of the advantages of having a suspended and rotated nanoparticle in a vacuum like this also means that accurate measurements can be made, without being affected by the standard variations in Airflow and temperature.

And this research group is not the only ones busy working to get nanoparticles spinning in a vacuum: further potential discoveries are significant.

For quantum mechanics, it helps scientists explain the behavior of the universe at a very small and really large scale - areas where classical physics models like us still know begin to work. use.

Having such a small object for testing can be thought of as a better understanding of how the building blocks of matter work at the smallest scales.
