Dark matter, dark energy0
19-Apr-2007 A new study of dark matter haloes shows they are shaped like frisbees, not rugby balls as had been suggested.
3-Apr-2007 Scientists propose a new model of large-scale gravitation in which the force on dark matter is different to that experienced by normal matter.
The Abnormally Weighting Energy hypothesis achieves a number of scientifically satisfactory outcomes: It agrees well with observation, particularly of distant supernovae. It does not require negative pressures. It predicts an age of the universe 3 billion years greater than current models. And unlike previous theories of dark matter, it does not lead to an exponentially expanding universe, but rather a normal Einstein-de Sitter space, in which expansion is slowed by gravitation.
Best of all, AWE explains with minimal change to existing physics the otherwise deeply mysterious “dark energy”.
4-Dec-2006 Observations from Hubble Space Telescope show that dark energy has been speeding up the expansion of the universe for the largest part of its existence. Story and science teaching resources (US or UK English) posted at www.realscience.org.uk
