The École Centrale de Lyon's Student Office (BDE), with the support of Director Frank Debouck, initiated a series of conferences in 2018. Under the name AGORA, the BDE invites specialists and gives them carte blanche.
The 2019-2020 cycle began on Monday 16 September with Françoise Combes, astrophysicist and member of the Academy of Sciences. She proposed a conference entitled: "Are the Black Holes too greedy?".
