Scientific breakthrough: scientists have created the world's most accurate nuclear clock

Published 2026-10-18

Scientists from the Vienna University of Technology have unveiled a unique development — the world's first nuclear clock. This device operates on the principle of utilizing the energy transitions of an atomic nucleus, which allows it to be significantly more stable than modern atomic counterparts.

The main feature of the invention is its incredible accuracy. According to the researchers' calculations, such a clock could lose only one second every 30 million years. For comparison, the standard atomic clocks we use today have a much higher margin of error.

The technology is also notable for its autonomy. The device is capable of self-correcting internal errors and can operate stably for over a day without external intervention. This achievement was made possible through the use of the latest laser technologies and research into the thorium isotope.

Scientists note that this invention opens up new possibilities for fundamental physics. High-precision time measurement will help us better understand the laws of the Universe, test the theory of relativity, and improve navigation systems used around the world.

Although the technology is currently in the laboratory research stage, it holds great potential for the future. In the long term, such clocks could become the foundation for ultra-precise communication systems and space exploration, where every fraction of a second is of critical importance.
