What is dark matter and why is it important for understanding the Universe?
This is one of the key questions in modern cosmology.
Dark matter is a mysterious form of matter that doesn't emit, absorb, or reflect light, making it invisible to direct observation.
However, it has a real gravitational effect on nearby matter and light—and it's through this effect that scientists have inferred its existence.

There is much more dark matter in the Universe than ordinary atomic matter.
It forms the gravitational "scaffold" on which galaxies and galaxy clusters are built.
Although we still don’t know what dark matter is made of and haven’t yet detected its particles, we see that its role in the evolution of the Universe is crucial.

In this video, we’ll explore the most popular facts about dark matter.
