Title: |
The dark side of the
universe: when light doesn't travel in straight lines |
|
Speaker: |
Richard Massey |
|
Description: |
Most of the Universe is made of mysterious
"dark matter" and "dark energy". Both ingredients are invisible - which
makes life difficult for astronomers - but we are beginning to get the first
picture of what they are. They give themselves away by bending light around
them, a characteristic effect first predicted by Albert Einstein. Richard
will describe how Arthur Eddington's 1919 observations of an African solar
eclipse demonstrated this effect and proved the general theory of
relativity. He will discuss a return expedition to celebrate the anniversary
last year and how the latest observations from the Hubble Space Telescope
are revealing the dark side of the Universe everywhere around us. |
