Challenging the Standard Cosmological Model

Some time ago I used the medium of this blog to plug a mini-conference at the Royal Society in London entitled Challenging the Standard Cosmological Model. Here’s a description of the meeting:

Is the universe simple enough to be adequately described by the standard ΛCDM cosmological model which assumes the isotropic and homogeneous Friedmann-Lemaître-Robertson-Walker metric? Tensions have emerged between the values of cosmological parameters estimated in different ways. Do these tensions signal that our model is too simple? Could a more sophisticated model account for the data without invoking a Cosmological Constant?

That conference is actually taking place this week (on 15th and 16th April, i.e. yesterday and today). I can’t be there, of course, because I’m here, but I can share the recording of the talks. Here is the first day’s worth. The recording is about 8 hours long so you probably won’t want to watch it all in one sitting. Let me point out the talk by Wendy Freedman, which starts at around 2:13.30 talking about the Hubble Tension largely from the point of view of stellar distance indicators and suggesting an answer of 69.1 ± km s-1 Mpc-1, which reduces the tension with Planck significantly.

And here is Day 2:

One Response to “Challenging the Standard Cosmological Model”

  1. I enjoyed Mohamed Rameez’s talk, that’s the kind of attitude I expected from more of the participants.
