100 anos de Relatividade Geral

Em 2019 comemoram-se 100 anos da confirmação experimental da Teoria da Relatividade Geral. As observações realizadas em 29 de Maio de 1919 no Príncipe foram um marco relevante para a História da Ciência e para a Ciência. Foram efetuadas observações que são um momento marcante da visão que temos hoje do Universo pois permitiram, pela primeira vez, verificar que os dados obtidos experimentalmente estão de acordo com a previsão da Teoria da Relatividade Geral de Einstein para a deflexão da luz pelo Sol.

Permitiram não só a projeção mediática de Albert Einstein, mas acima de tudo, a verificação experimental de uma previsão da teoria, que levou a comunidade científica a encarar a gravidade de uma forma totalmente inovadora e que ainda hoje desafia as maiores mentes do nosso tempo.

Durante o eclipse solar de 29 de Maio de 1919, a ilha do Príncipe, uma ilha na costa Oeste de África e o Sobral, no Brasil, foram palcos de observações astronómicas históricas de um eclipse solar total levadas a cabo por um grupo de astrónomos liderados por Arthur Eddington numa expedição conjunta entre a Royal Astronomical Society e da Royal Society.
