Hello and welcome to the Oxford University Physics Society (or PhysSoc for short)! This year, we have plenty of events on, including talks, socials, extracurricular classes and much more. This isn’t a society just for physicists; this is a society for anyone who is interested in physics, its applications, and physics-related topics. To find out more, have a look at our Youtube channel, our Facebook page or subscribe to our mailing list.
How do I get involved? Simple. Head over to the How to Join page and follow the instructions there.
Keep it |ψ|!
Week 1, Thursday, Prof. Subir Sarkar: “Beyond the Standard Cosmological Model”
The `standard model’ of cosmology is founded on the basis that the expansion rate of the universe is accelerating at present — as was inferred from the Hubble diagram of Type Ia supernovae. There now exists a much bigger database of supernovae so we can perform rigorous statistical tests to check whether these `standard(isable) candles’ indeed indicate cosmic acceleration. We find, rather surprisingly, that the inferred acceleration is mainly along the direction we seem to be moving with respect to the cosmic microwave background. It cannot therefore be due to the Cosmological Constant (aka vacuum energy), even though a variety of observations are supposed to have meanwhile confirmed its presence. This is an exciting time to be a cosmologist!
