Physics Colloquium Speaker Robert Brandenberger Affiliation McGill University Title of talk Do we understand early Universe cosmology? عنوان: آیا کیها‌ن‌شناحت جهان اولیه را می‌فهمیم؟ Date and time, 6-7:30pm, Wednesday 21 May 2025 (31 Ordibehesht 1404) Venue: Online Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract I will argue that the usual effective field theory techniques break down in the rapdily expanding background of the early universe. The TCC ("Trans-Planckian Censorship Criterion") plays a key role in the argument. I will then discuss an attempt to obtain an emerging metric space-time and early universe cosmology starting from a quantum mechanical matrix model.
