On Friday, Jan. 20, renowned astrophysicist Rocky Kolb from the University of Chicago spoke as a part of Fermilab’s Public Lecture Series and reminded us that there is still much to discover about our cosmos.
Kolb opened his lecture by examining the possibility of other “earths” among neighboring stars and then switched to a discussion about his two areas of research: graviton detection and the search for dark matter. Kolb explained that looking through a telescope is actually looking back in time because it takes many years for the light from distant galaxies to reach us. He then showed the audience images of ancient light collected by a telescope and brought us back to a few seconds after the Big Bang.
The images raise more questions than answers: What is dark matter? What happened to all the antimatter? And where are the gravitons that pull it all together? He then explained the curious theory of quantum expansion that created all matter and emphasized that we ourselves are “an amplified quantum expansion.” Kolb ended his talk with a discussion about the future of cosmic research, where it’s headed and how important it is for today’s youth to carry the torch and continue on the path to discovery.
The full talk will be posted on the Fermilab VMS website within the next few weeks.
