Beyond light
Here, in the Universe series

A colisão de corpos de extrema densidade, como buracos negros e estrelas de neutrões, produzem ondas gravitacionais

Albert Einstein previu, há mais de 100 anos, que o tecido do espaço-tempo, para além de ser curvado pela presença de matéria, também pode vibrar – refletindo-se na variação periódica da distância entre dois pontos. A colisão de corpos de extrema densidade, como buracos negros e estrelas de neutrões, produzem ondas gravitacionais com amplitude suficiente para serem detetadas pela tecnologia atual.

The third session of the lectures series Aqui, no Universo (“Here, in the Universe”), organized by Culturgest in partnership with Instituto de Astrofísica e Ciências do Espaço (IA).

With Lara Sousa and Sofia Andringa, and hosted by Filipa Melo

In addition to meteorites, the light of stars and planets, and radio messages from space missions, what other information comes to us from space? What invisible messengers can we ask about what exists outside the Earth?

High-energy subatomic particles produced by extreme phenomena – cosmic rays – light and elusive, almost undetectable particles, such as neutrinos, and the tremors in space-time predicted by Einstein and recorded for the first time in 2015 – gravitational waves – generated by the densest concentrations of matter, black holes, which has opened new windows of information about a Universe on the edge of light, and still almost unknown.

Lara Sousa, of the Instituto de Astrofísica e Ciências do Espaço (IA) (Institute of Astrophysics and Space Sciences) and Sofia Andringa, of the Laboratório de Instrumentação e Física Experimental de Partículas (LIP) (Laboratory of Instrumentation and Experimental Particle Physics), tune the Universe through some of these alternative channels. It’s this in which they seek to complement the images and light collected by telescopes, with the aim of, little by little, revealing the stories of the invisible Universe that are yet to be told.

The host will be Filipa Melo, writer, university professor and literary critic.
