The Expanding Universe Dr Bob Lambourne Meeting : 11
October 2007 |
|
|
An
expanding universe is any model universe in which the space between widely separated
objects is expanding. In the real Universe, neighbouring objects such as
close pairs of galaxies do not move apart because their mutual gravitational
attraction exceeds the effect of the cosmological expansion; but the distance
between two widely separated galaxies, or clusters of galaxies, will increase
as the Universe expands. Bob Lambourne’s extensive experience and
knowledge were again demonstrated with this presentation on cosmology, the
microwave background, and many of the latest discoveries and conclusions
concerning redshift. |
