The half-life of xenon-124 is an incredibly rare phenomenon in the entire Universe

A group of scientists from Europe, USA and Middle East have recorded the rare phenomenon in the Universe. To see this event helped a detector of dark matter XENON. It is reported by Sci-News.

Detector dark matter XENON

It was originally designed to detect potential dark matter particles — weakly interacting massive particles, known as wimpy. To avoid interference a special camera placed deep underground and filled with ultra pure liquid xenon-124. The equipment would capture the characteristics of the interaction of particles. So scientists hoped to obtain the first direct proof of the existence of vinow.

The glow of the isotope xenon-124

But the detector did not reveal any traces of dark matter. Instead, the participants of the scientific experiment was able to observe the decay of atomic nuclei of xenon-124. The half-life of most isotopes of xenon is less than 12 days. Xenon-124 is an exception. According to scientists, the half-life of 18 sextillion years, which is a trillion times the age of the Universe itself.

We will remind that earlier scientists have questioned the existence of dark matter. Also physics has called into question the basic theory of Stephen Hawking.
