scientists announced today new evidence supporting the theory that the infant
universe expanded from subatomic to astronomical size in a fraction of a second
after its birth.
the finding is based on new results from nasa's wilkinson microwave anisotropy
probe (wmap) satellite, launched in 2001 to measure the temperature of radiant
heat left over from the big bang, which is the theoretical beginning to the
universe.
this radiation is known as the cosmic microwave background (cmb), and it is
the oldest light in the universe.
using wmap data, researchers announced in 2003 that they had pieced together a
very detailed snapshot of the universe as it was about 400,000 years ago, and
that they had determined things like its age, composition and development.
the previous data showed that the universe was about 13.7 billion years old.
it also revealed that it wasn't until about 200 million years after the big bang
that conditions were cool enough for the first stars to form. scientists were
also able to conclude that the universe is composed of about 4 percent real
matter, about 23 percent dark matter, and about 73 percent dark energy. nobody
actually nows what dark matter or dark energy are, however.
