What happens when the Universe ends?


TORONTO, Tuesday, Feb. 25, 2020 – How does it all end? Does the Universe end the same way it started, with a bang? Media are invited to hear theoretical astrophysicist and science communicator Katie Mack discuss what modern astrophysicists believe will happen in the end, in her talk Death of a Universe, at York University.

The Big Bang theory is widely considered the best explanation of how the Universe began some 13.8 billion years ago, but there are several ways it could end. Mack will explore what each possibility would entail if there were anyone still around to see it.

Mack investigates the connections between the subatomic world and the Universe as a whole, including dark matter.

WHAT: Talk titled, Death of a Universe, followed by a Q&A session, a tour of the Allan I. Carswell Observatory and a public viewing of the night skies

WHO: Assistant Professor Katie Mack, a theoretical astrophysicist and science communicator at North Carolina State University

WHEN: Thursday, Feb. 27, from 6:30 to 9 pm

WHERE: Tribute Communities Recital Hall, Room 112, Accolade East Building, Keele Campus, York University

The event is hosted by Future Women in Physics at York and the Faculty of Science’s Department of Physics and Astronomy.
