Hidden in the large-scale structure of the Universe – the so-called cosmic web, subtle waves provide a priceless view on the cosmos, helping scientists highlight some of the mysteries about its structure, evolution, and its current accelerated expansion governed by dark energy. This phenomenon is known as Baryon Acoustic Oscillations (BAOs). To understand what they are, we must travel back in time to the early Universe! Are you ready?

Gravitational lensing is a fascinating phenomenon that happens because of the way gravity works according to Einstein’s theory of General Relativity: mass curves spacetime. Imagine you have a massive object, like a star or a galaxy, sitting in space. This object has a strong gravitational pull, which means it will bend spacetime and – since light follows a path along this now bent space – it also bends the path of light that passes nearby.

Dark Matter is not one of the powerful sith lord in the Universe, but is one of the biggest mysteries in astrophysics. It refers to a transparent form of matter that does not interact with light, making it invisible to our telescopes. Nevertheless its presence can be inferred through its gravitational effects on usual visible matter and the large-scale structure of the Universe.
