Hubble’s law: v = H0D implies uniform expansion of the
Universe
Recent studies have shown that the expansion of the Universe is
speeding up because of a repulsive force (anti-gravity) whose
source is termed “dark energy”
All parts of the Universe, including the rulers we use to
measure distances, are expanding uniformly
The reverse extrapolation of the expansion of the Universe
leads us to believe that the Universe started with the Big Bang
Scientists believe that there is no preferred point in our
Universe that could be termed the “center of the Universe”
