Bharat Ratra, A Shock in the Dark:
The Forces Expanding Our Universe 

Thursday, October 5, 2023, 5:15 p.m.

Donald W. Reynolds Razorback Stadium is big. So big it holds more than 70,000 people. Yet, if
you were to pick up Razorback Stadium along with the rest of Earth and every other planet
observed with modern instruments, you would only be holding less than a measly 5 percent of
the universe.

The bulk of the mass of the Universe now is dark energy, followed by dark matter.
We are still in the dark with dark energy. The intricacies of it are unknown, but Bharat Ratra, a
Distinguished Professor of physics at Kansas State University, has dedicated his research to
determining whether dark energy is responsible for the speeding up of the expansion of the
Universe. In fact, the discovery that cosmological expansion is accelerating is one of the most
significant scientific discoveries of the last quarter century.

Ratra’s research tells us that the universe is expanding, and so are the opportunities to learn
more with the Honors College. Join us and Ratra for an illuminating chat about dark matter,
dark energy and Einstein’s cosmological constant at the next Honors College Mic at 5:15 p.m.
Thursday, Oct. 5, 2023, in Gearhart Hall Auditorium.
