Universo peregrino: ciencia galega cara o mundo

“Universo peregrino: ciencia galega cara o mundo” (Pilgrim Universe: Galician science towards the world) is a series of online outreach talks organized by the Galician Institute of High Energy Physics (IGFAE) of the University of Santiago de Compostela for the Galician-speaking international community. In moments of isolation in which pilgrims cannot come to Santiago, the Xacobean city is the one that rebuilds the bridges and undertakes the pilgrimage to the world. Every Thursday in May and June 2020, at 16:00 (Madrid time), IGFAE researchers will give a talk on various physics topics that can be followed online. The videos will be uploaded to our Youtube channel afterwards.

May 28th. Héctor Álvarez Pol: “Do corazón da materia ao interior das estrelas” (link to live talk)

Cibrán Santamarina explains in this first talk the origins of matter and how particles such as the Higgs boson are investigated at CERN.

Sometimes, finding the origin of the smallest things we can imagine requires discovering how stars are born and die. And the mechanisms that we invent in the laboratory to understand the mysteries of the atomic nuclei are useful to diagnose and cure diseases. We will do a brief review of the subatomic world, reminding ourselves that we are all stardust.

Where does all that we see around us come from? A century ago this question was outside the realm of physics, but the scientific advances that have taken place in the last 100 years answered many questions about the origin and evolution of the Universe. In this talk we will make an introduction to the most remarkable achievements of this intellectual endeavor and explain the role that Stephen Hawking played in it.

Four fundamental forces can govern from the largest to the smallest objects in the universe. The gravitational interaction was the first to attract the attention of the great thinkers of antiquity, who were already raising their heads and trying to explain the intricate movements of the stars. In this third talk of Universo Peregrino we will see that there are many questions left to answer.
