Monthly Meeting: Dr. Luke Hart – “Cosmic Microwave Background Radiation: Ripples from the Big Bang”

Friday, 18th March 2022 @ 19:00 - 21:00 GMT

The March 2022 monthly meeting of Liverpool Astronomical Society for the 2019 – 2022 (138th) session will be held on Friday, March 18th from 19:00 to 21:00.

Our guest speaker this month is Dr. Luke Hart, Software Engineer at TNEI Services Ltd. focusing on power systems analysis, part of the ESA New Horizons Spectral Distortion Working Group and postdoctoral researcher, PhD student and MPhys student at the University of Manchester. Luke’s lecture is entitled:

“Cosmic Microwave Background Radiation: Ripples from the Big Bang”

There have been lots of amazing astrophysical discoveries in the 20th century including the first pulsars, the birth of radio astronomy and even the first attempts at using supernovae to explain stellar life cycles. One of the most important however has been the discovery and subsequent understanding of the microwave background radiation (CMB) – the peculiar relic signal that echoes from the Big Bang epoch itself. In this lecture, I will broach the history of the Big Bang and how it was discovered, discuss what the fuss is all about: how a tiny ripple in a sea of light can give us the subtlest of clues about our own universe’s understanding. I will try to link in recent research and modern satellites, theories and other advances in the field of modern cosmology and how they relate to the CMB. To conclude, I will talk about the most exceptional of advances in theoretical cosmology and how these tiny little flickers in the signal could potentially allow us to look even further back than before.


This meeting will be held at our normal venue of the Quaker Meeting House, but will also be live-streamed via Zoom and YouTube.

Society members have been sent a Zoom invite.
A recording IS publicly available for this lecture »»» at this YouTube link.
