תקציר ההרצאה

One hundred years ago, Einstein famously introduced an extra term into his equations to describe a static universe.  A decade later, when astronomers found the Universe is not static, but expanding, he discarded that "cosmological constant."  In the past 20 years, astronomers, including Prof. Kirshner, have found that cosmic expansion is speeding up, driven by a mysterious “dark energy” whose nature we do not fully understand, but which makes up ~70% of the mass-energy in the Universe and which bears an uncanny resemblance to Einstein's idea.
