Scientific Halloween takes place in Ufa Planetarium today

UFA, 31 October 2017. /Bashinform News Agency, Galiya Nabieva/. Today Halloween will be celebrated scientifically in Ufa Planetarium. The joke lies in the fact that physicists suggested to celebrate "Dark Matter Day" on October 31 on the Halloween holiday, the planetarium informs.

Dark matter is 85% of matter in the universe. But since it does not emit electromagnetic radiation and does not interact with it, it is not recorded through direct observations. That is, for science it is a kind of ghost of unknown nature. It is also elusive, like those spirits and evil spirits that penetrate our world on the eve of November 1, whose holiday, in fact, is Halloween according to the beliefs of the ancient Celts.

All over the world, particle physicists conduct activities regarding their search for dark matter.

Ufa Planetarium timed to the Dark Matter Day a premiere of the full-dome film "Phantom of the Universe: the Hunt for Dark Matter" with comments of an astronomer. Beginning is at 7 pm, admission is free.
