Math Encounters:

"The Structure of Space: Measuring the Shape of the Universe" with David Spergel

Wednesday, July 7 at 7:00 pm ET (New York)

In person!

Is the universe infinite or finite?  Will it expand forever or collapse in a hot Big Crunch?  And what is its shape?  Join David Spergel, Director of the Center for Computational Astrophysics, Flatiron Institute, as he introduces geometry and topology, the mathematical concepts used to answer these questions.  Learn how observations of the microwave background (the leftover heat from the Big Bang) have revealed the universe’s shape and can help predict its destiny.

Special introduction by Janna Levin, Claire Tow Professor of Physics and Astronomy at Barnard College of Columbia University.

This event will take place in person at MoMath at 11 East 26th Street.

All in-person seats are available on a first-come, first-served basis.

MoMath requests that unvaccinated guests wear masks.

Please arrive 15 to 30 minutes before the event to complete registration.

This event is free, but a $25 donation will help MoMath defray reopening costs as patrons are welcomed back to the physical Museum.
