Join C2ST and cosmologist, Dr. Chihway Chang for a presentation on this mysterious force. Together we will seek to answer questions such as:
- What is dark energy in simple terms?
- Why is dark energy important to us?
- Is dark energy everywhere?
- And how does dark energy affect humans?
According to Einstein’s theory of General Relativity, gravity should slow cosmic expansion. Yet, in 1998, two teams of astronomers studying distant supernovae made the remarkable discovery that the universe’s expansion is speeding up. To explain cosmic acceleration, cosmologists are faced with two possibilities: either 70% of the universe exists in an exotic form, now called dark energy, that exhibits a gravitational force opposite to the attractive gravity of the ordinary matter, or General Relativity must be replaced by a new theory of gravity on cosmic scales.
