In the celebrations of the total solar eclipse of 1919, take part in astronomical observations, guided visits to a historical observatory, and a public talk dedicated to Einstein’s contribution to science.
The 29th of May marked the centenary of the observations of the total solar eclipse of 1919, in Sobral (Brazil) and Príncipe (São Tomé e Príncipe), which resulted in the confirmation of one of Einstein’s General Relativity Theory predictions.
The concept of a Block Universe, in which the past, present and future coexist, partly appears within the context of Einstein’s relativity theories. It represented a step forward in the removal of time from Physics theories, which was not totally reasonable for Einstein, as noticed in his hesitation in recognizing that these scientific descriptions failed to completely satisfy our human needs; there is something essential about the Now (the present moment) that is outside the realm of science.
It is within this context that Paulo Crawford, from Instituto de Astrofísica e Ciências do Espaço, will discuss the concept of Newton’s absolute time versus Einstein’s relative time, the removal of time in the frame of a Block Universe and the Rebirth of Time, within Cosmology, in a never ending conciliation struggle between general relativity and quantum theories.
All activities are free, but the talk is limited to the number of places available. The guided visits to the observatory require prior registration upon arrival.
The Origin of Time in Cosmology: back to Einstein’s message (in Portuguese)
by Paulo Crawford, from Instituto de Astrofísica e Ciências do Espaço (IA) and Faculdade de Ciências da Universidade e Lisboa (FCUL).
