The concept been given main boosts from Edwin Hubble's observations that galaxies are speeding faraway from us in all directions, and through the 1960s discovery of cosmic microwave radiation—interpreted as echoes of the big bang—by Arno Penzias and Robert Wilson.
It isn't clear what the final word destiny in the universe is. At present some cosmologists take into consideration the universe will proceed to expand, finally cooling off, or “freezing out”. That may end in the heat death of your cosmos.
