The Sun will shine directly on the Earth's equator, casting both north and south hemispheres in equal day and night. It's the first day of spring in the north and the first day of fall in the south.

Centuries of astronomy and cosmology have led to an ever-larger picture of our ‘universe’ — everything that we can observe. For just as long, there have been speculations that there are other regions beyond what is currently observable, each with diverse histories and properties, and all inhabiting a ‘Multiverse’. Dr. Matt Johnson of York University & the Permiter Institute joins us to talk about the "Multiverse" concept and will discuss the first observational tests to prove they exist.
