Presenter: Dr. Rutuparna Das, Astrophysicist with Harvard University, Center for Astrophysics

The meeting will take place at 7 PM at the Robinson Nature Center and on Zoom.
Topic: Shedding Light on the Dark Side of the Universe
Brief description of the Discussion:
Our universe is expanding. Not only is it getting bigger and bigger, it’s accelerating. This mind-boggling revelation of the 90’s has opened up a treasure trove of questions about our cosmos. What is causing this acceleration? Will the universe always behave like this, or will it someday start slowing down? And how do we find out?
This last question is more complicated than it may seem at first glance. “Dark Energy” is the name given to the cause of the universe’s acceleration. We cannot see it, and we do not know much about what it is. To try to comprehend its effect on our cosmos, we turn to Dark Matter, yet another component of the universe that we cannot see. How do we quantify this invisible matter, use it to understand this invisible energy, and then use that to explore the fate of our universe?
Bio: Rutuparna Das is an astrophysicist and science communicator who spends her time learning about the universe and sharing its wonders with everyone around her. After going to undergrad at MIT, she completed her PhD at the University of Michigan, where she worked on weighing clusters of galaxies and figuring out what the cosmos is made of. She’s now at the Center for Astrophysics | Harvard & Smithsonian, spreading the joys of space through NASA’s Universe of Learning, and continuing her research into the composition of the universe. When she’s not staring at the sky (both with her naked eyes and through data from giant telescopes), she enjoys reading, crafting crazy desserts, taking an inordinate number of nature photos, and writing (sometimes silly) poetry about the cosmos.
