Challenging the standard cosmological model, London, 15-16 Apr 2024

Post by Subir Sarkar » November 17 2023

https://royalsociety.org/science-events-and-lectures/2024/04/cosmological-model/

Scientific discussion meeting organised by Prof James Binney FRS, Dr Roya Mohayaee, Prof John Peacock FRS & Prof Subir Sarkar
15-16 April 2024, 09:00-17:00, The Royal Society, London SW1Y 5AG
Enquiries: Scientific Programmes team <[Log in to view email]>

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?

Free to attend - both in-person and on-line attendance available.
Advance registration is essential (an optional lunch is available to purchase during registration): https://rsproduction.powerappsportals.com/events/details/?id=a620b6c7-3a68-ee11-9ae7-6045bdf1e702

Dear Professor Sarkar,

I wonder if poster papers will be considered for inclusion in the Philosophical Transactions of the Royal Society A.

How much is the registration fee for participating in the meeting?

Thank you.

Sincerely,
rajendra gupta

There is no registration fee. Only invited talks are published in the Proceedings.

The meeting room is now full - but registration for on-line participation will remain open.
