As a part of the international conference "Geometric Foundations of Gravity 2019" held in University of Tartu, Institute of Physics, there will be a public talk in English on Tuesday, 18 June 2019 at 6 p.m. in the Tartu Old Observatory (on Toomemägi).
Professor Lavinia Heisenberg (ETH Zürich) will speak on the topic "Our Dark Universe", explaining the recent advances in attempts to solve the puzzles of our universe (like dark matter and dark energy).
Even though the gravitational interaction was the first fundamental force ever discovered, it still remains the most intriguing one. Its most distinctive property is its intimate relation with the geometry of the space-time as Einstein brilliantly formulated in his theory of General Relativity. However, in order to describe the cosmological observations, this standard picture requires the introduction of two unknown ingredients, namely dark energy and dark matter. Could this signal the breaking of General Relativity? I will discuss some alternatives to this standard picture.
Everybody is welcome to attend, the entrance is free.
