The next Jerzy Pniewski and Leopold Infeld Colloquium of the Faculty of Physics will be held on Monday, JUNE THE 7TH, at 4.30 PM.

Thanks to a discovery made in 1929 by Edwin Hubble, we know that the universe we live in is constantly expanding. One would expect that the rate of expansion, slowed down by gravitational interaction, would decrease with time. However, there is a surprising acceleration of this process. Moreover, there is no consensus on the rate at which the expansion occurs. Depending on the measurement method, significantly different results are obtained, which calls into question our understanding of a number of laws of physics. These issues will be the subject of a lecture entitled:

PRECISE DETERMINATION OF THE COSMIC DISTANCES AND THE UNIVERSE'S EXPANSION MYSTERIES,

delivered by

PROF. GRZEGORZ PIETRZYŃSKI (ASTRONOMICAL OBSERVATORY, UNIVERSITY OF WARSAW)

The abstract of the lecture is provided below this message.
