What is the adverage time for this to happen?
I read an article that said that the normal time is less than 10billion for the galaxies to start forming together, but what is the typical time for this to happen?
Thankyou(:
About a billion years, give or take. 10 billion is almost the whole age of the Universe.
Calculation:
Typical distances involved: 300 kpc
Typical velocities: 300 km/s = 300 kpc/Gyr
Typical time = 300 kpc/ 300kpc/Gyr = 1 Gyr
