Repulsive Astronomy: Strengthening the case for dark energy
Ron Cowen

Astronomers have found new evidence for one of the strangest properties
of the universe. A mysterious substance, dubbed dark energy, appears to
be ripping the cosmos apart, causing the universe to expand at an
ever-faster rate.

The wrenching findings come from a correlation between two kinds of sky
maps-one that denotes the positions of large numbers of galaxies and
another, a snapshot of the cosmic microwave background, which is the
remnant radiation from the Big Bang.

By comparing the maps, astronomers have found the imprint of dark
energy, which pushes objects apart and thus counters gravity's familiar
tug. Previous support for dark energy has been based on the brightness
of distant stellar explosions known as supernovas (SN: 3/31/01, p. 196:

evidence, however, some researchers weren't convinced.

"Since the implications of dark energy are so profound for physics,
having multiple, independent lines of evidence for its existence is
absolutely essential," says Joshua A. Frieman of the Fermi National
Accelerator Laboratory in Batavia, Ill., a coauthor of one of four
dark-energy studies recently posted online. Each study uses data from
the Wilkinson Microwave Anisotropy Probe (WMAP), a satellite that is
generating detailed maps of the cosmic microwave background (SN:
2/15/03, p. 99: http://www.sciencenews.org/20030215/fob1.asp).

The outer edge of the universe is speeding up by anti-gravity.
Just as time slows down in gravity - time and light speed up by
anti-gravity.
This could cause time to possibly move equally for objects being moved
away from each other by this force.
Understanding that this is happening to space-time at its edge
is for me the end of physics.

Anti-gravity is stretching space-time causing light to move faster
there.
Just as there is contraction there is space-time expansion. Light
goes fsster in this faster time.
