On 31 October 2019, the JINR Universal Public Library invites to celebrate the International Dark Matter Day, a scientific Halloween.

Dark matter doesn’t interact with light but accounts for 85% of all the matter in the universe. It’s completely invisible to us, yet distorts space and somehow binds galaxies together – we only know it exists because of its gravitational effect on visible matter. Dozens of experiments are underway around the world, working to better understand dark matter and hopefully detect an interaction. This year, the Nobel Prize in Physics was awarded in part for discoveries in theoretical cosmology that contribute to our knowledge of dark matter and its role in the early universe.

What keeps galaxies from flying apart? What is the invisible mass that bends light in space?

Let’s figure it out! Come and join the International Dark Matter Day on 31 October in the JINR Universal Public Library (13, Blokhintsev str).

Following a tradition, the programme will be divided into two parts: the scientific-educational and popular science. This year, a quest will be prepared for children as well. The start of events for children is set at 5:00 PM, for adults – at 6:30 PM.
