How many galaxies are there in the universe?
it is believed that there are about
But that's really an estimate of number of galaxies and stars they might differ but till now it is believed to be accurate .
As there are numerous galaxies in our universe and all are moving far away (big bang theory <which proves that the galaxies are moving far away from each other , as the distance between the galaxies increases their speed also increases > ) .
Accurate number of galaxies as per me could only be measured when this universe collapses again after billions of years ( as per pulsating universe theory < a theory according to which the universe would expand for a great duration of time and would again collapse >).
