"Data-reactid =" 24 "> The XENON experiment is designed to detect dark matter, the dark thing is not mysterious, the reason is that it is hardly ever to do it, it's hard to spot it. Clearly and without magnetic field, it almost never interacts with any normal association in any way.

In order to see the impact of a dark matter part, scientists can create extravagant experiments. One of them is the XENON observatory, which is essentially a liquid xenon tank, sitting in the basement of an Italian laboratory. This is little: the laboratory is about one kilometer long and the tank has 3.5 xenon tons.

The experiment uses xenon because it is one of the most important elements in the universe. Nothing reacts with xenon, especially under the underground mileage, which makes dark matter a perfect detector. After all, the dark matter reacts with Xenon, as it reacts with all, so XENON team 11.

Although it is not enough to find dark matter yet, it was enough to see the decay of a xenon-124 atom. Xenon-124 is a radioactive isotope, which lasts for an average of 1.8 years. To date, the life of the whole universe is 130 thousand million times longer. The Xenon-124 atoms disintegration is not uncommon.

And yet, he saw a XENON observatory, and the detective was sufficiently sensitive to pick and record. When XENON detects a rare event like xenon-124 disintegration, it will be able to see a dark matter that clashes with one of these xenon atoms. Now XENON team has to wait for everything.
