Since the beginning of the 20th century, huge breakthroughs have been made in the field of physics. But many mysteries are still waiting to be revealed. In astrophysics and cosmology, dark matter is one of the great unknowns that remains today. It escapes the Standard Model, and is estimated to account for more than 80% of the matter that exists in the entire Universe. However, we can only “see” it through the gravitational effects it causes, as it does not emit any electromagnetic radiation.
SA2_GRWA
The first experimental detection of gravitational waves, obtained by the LIGO collaboration in 2015, is one of the great scientific milestones of the 21st century. These ripples in space-time are caused by some of the most violent cosmic phenomena, such as the mergers of black holes and neutron stars or supernova explosions. In this way, these events contribute to validate the theory of general relativity put forward by Einstein in 1915.

We are exposed to a constant ‘bombardment’ of cosmic rays, which impact with us at near-light speeds. Approximately at a frequency of one ray per second on a surface like the palm of your hand. Luckily, these are harmless radiations, but fascinating because they come from far, far away in the universe.
