flaws in the ‘big bang’ theory?
But the official “age of the universe” has changed
with new discoveries. In the late 1950s and early
1960s astronomers identified objects called quasars,
which have a redshift greater than anything
previously observed in the heavens.
Applying the standard interpretation, astronomers
concluded that these objects must lie at the farthest
reaches of the universe, and the universe must be
bigger than previously thought.
Quasars also posed another dilemma. Based on
redshift, astronomers concluded that while
quasars appear dim and red in our sky, they are
actually very bright, but just very far away.
Based on redshift and at the distances claimed,
it would take hundreds of galaxies to produce
this brightness as seen from Earth.
Two Chandra observations of
the giant elliptical galaxy M87
were combined to make this
long-exposure image.
