What happens when the universe gives you too much data, conflicting answers, and a mysterious force that might be changing with time? From compressed cosmic surveys to dueling expansion rates and dark energy on the move, this night tackles the universe’s juiciest mysteries with cutting-edge tools and cosmic curiosity.

Faster analysis of the universe with compression

Yan Lai (PhD candidate, University of Queensland)

Imagine trying to take a photo while on vacation, but your phone tells you the storage is full. Scientists encounter a similar problem while analysing vast amounts of data from the latest universe surveys. In this talk, Yan Lai will explain a faster method to analyse the data by compressing it.

A crisis of cosmic scale

Leo Giani (Post-doc, University of Queensland)

We have known that the Universe is expanding since the 1920's, yet we still don't know how fast! After a decade of research there are two equally reasonable yet fundamentally incompatible measurements that are challenging our understanding of gravity and the Universe. In this talk Leo Giani will introduce you to the biggest crisis of modern astrophysics—and the "gravity" of the situation.

A New Hope for the Universe: Is Dark Energy Weakening?

Dr Rossi Ruggeri (Lecturer, Queensland University of Technology)

Latest results suggest dark energy might not be constant, challenging our understanding of the universe. Join Rossi Ruggeri to explore how the largest 3D map of the cosmos reveals hints of evolving dark energy — and what it could mean for the fate of the universe.
