UofT AstroTour: Surfing Through Spacetime on Top of Gravitational Waves
Foreseen by Einstein almost a century ago, gravitational waves were for a long time the last prediction of his theory of general relativity left to be confirmed. Last September, LIGO directly observed these waves being emitted from the merging of two black holes 1.3 billion light-years away. Thus, we opened a new window into the workings of our universe. In this talk, Alex Rachkov will cover what these mysterious waves are, recount the long journey of their discovery and the significance they have for the future of astronomy.
About the Speaker
Aleksandar Rachkov is a second-year PhD student in Astronomy and Astrophysics at the University of Toronto. His work involves studying the stability of the Solar System in the future and whether Mars could crash eventually into Earth. As a kid, he read an Arthur C. Clarke novel about using wormhole technology to transmit information and has been since then fascinated by the Universe and all its mysteries. In his free time, he enjoys reading science-fiction and talking about astronomy with anyone who would listen.
The U of T Astronomy Public Tour, or AstroTour, is a monthly event operated by the graduate students of the U of T Astronomy Department. The Tour features a public lecture by a member of the Department on topics ranging from their research to great moments in astronomical history. Following the lecture, tour-goers can peer at the night sky through the Department’s balcony and dome telescopes, or watch a planetarium show run live by astronomer. Admission to the tour is free. Seating for the lecture is on a first-come, first-served basis (doors open ten minutes before the start of the lecture), and the telescope observing is walk-in.
Who can attend: Everyone
Fee: Free
Reservations: Only required for Planetarium Shows (available March 31st at noon)
Organized by: Graduate Astronomy Students Association. The AstroTours are generously financed by the Department of Astronomy & Astrophysics and the Dunlap Institute for Astronomy & Astrophysics.
Location: University of Toronto, McLennan Physical Laboratories (MP 102), 60 St George St., Toronto, ON M5S 1A7
