Red shit
shows the universe is expanding, initially must have been formed from a single point
what is CMBR
cosmic microwave background radiation
what is cosmic microwave background radiation
the remains of the thermal energy from the big bag spread thinly into microwaves - spanning the whole Universe
two main reasons for the Big Bang theory
More distance galaxies move away from us faster - more distant galaxies have greater red-shift
Initial big bang heat is now spread thinly across the universe - CMBR is everywhere at -270*C
which came first
the discovery of red-shift led to the development of the BBT, the discovery of the CMBR provided very strong support for it
