The ultimate force in the universe: Some thoughts about gravity. ... Gravity through the ages Aristotle: Earth, water, fire, air. Earth and water fall `down' to the center of the cosmos (geocentric or earth centered universe). The more earth or water in the object, the faster it is attracted to the center. ... Determines the fate of the universe (expand forever, or contract back in a `"big crunch"). ... Determines the fate of stars when they die (white dwarfs, neutron star, or black hole). ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
