This research investigates whether dark energy, responsible for the universe’s accelerating expansion, evolves over time rather than remaining constant. Using galaxy distributions, supernovae, and cosmic microwave data, new statistical methods suggest evolving models may better fit observations, potentially reshaping our understanding of cosmology and the universe’s long-term fate.

My talk explains how neutron stars—extremely dense remnants of stellar explosions—contain matter we cannot study on Earth. By analyzing gravitational waves from colliding neutron stars, the speaker models how their deformation (or “squishiness”) reveals their internal composition. This method may uncover entirely new forms of matter and transform fundamental physics.
