DDO Astronomy Night: Weighing the Universe With a Balloon-Borne Telescope (ONLINE)

Weighing the Universe With a Balloon-Borne Telescope
Saturday, May 23, 2020 - 7:30pm to 9:00pm

Not only is the Universe expanding, but it’s also accelerating! This revelation implies either our understanding of gravity is flawed or that a mysterious negative pressure known as Dark Energy is driving the expansion. It turns out that the contents of the universe can be divided into three groups: dark energy, dark matter and the matter that is everything we can see and interact with, which only accounts for 5% of the universe!
 
One way to understand the relationship between these three groups is to find out how heavy they are! Unfortunately, there are no universe-sized scales so instead we have to build an experiment to weigh the universe for us! Mohamed Shaaban will join RASC at the DDO to talk about this exact experiment, the SuperBIT, which is a UofT-led collaboration with Princeton U, Durham U, NASA JPL, and the CSA.
