Early Universe from Home 2025 has ended. The public talks from the conference are all available in this YouTube playlist. Stay tuned for the announcement of Early Universe from Home 2026 next year!

Early Universe from Home is an online cosmology conference with an innovative format. This format, pioneered by Cosmology from Home, produces a dynamic and collaborative workshop experience within the online domain. It includes the use of pre-recorded talks, and a combination of asynchronous and scheduled live discussions. A permanently available and freely-navigated discussion space also facilitates ongoing, organic discussions.

The conference will bring together cosmologists from around the world to discuss, and share ideas on, cosmological correlators, phase transitions, topological defects, primordial black holes and other early structure formation.

Pedagogical Talks

• Richard Easther (The formation and evolution of structures – before and during reheating)

• Anne Green (The observational status of primordial black holes in 2025)

• Daniel Baumann (Correlators and their usefulness to other early universe fields)

• Ryusuke Jinno (What is interesting in early universe, phase transition research in 2025?)

Planned Themed Discussions During the Event

• Early universe candidates for the origin of supermassive black holes at the centres of galaxies.

• The memory burden effect in evaporating primordial black holes: How seriously should we take it and what are its consequences?

• Constraints and consequences of different axion masses in the post-inflationary scenario.

• Usefulness of “correlators” for early structures, phase transitions and topological defects.

• Status of gravitational wave predictions from first-order phase transitions.

• …

• Many more on topics suggested by participants during the event.
