OK, I Think I figured something out.
I saw the Hubble deep field scan
the picture that was taken of a 1mm by 1mm section has at least 10,000 galaxies in it.
To figure the surface are of the sphere that Hubble would be traveling on
4*pi*r^2
r of earth 6378
hight of Hubble 559
r of sphere 6378 + 559 = 6937
4*pi*6937^2 is 604718497 km
km to mm x6.04718497 x10^14
sphere so the estimate-able number of galaxies visible by Hubble would be 6.041897*10^14*
10000= 6.041897*10^18
According to wikipedia there are 100 billion (10^11) galaxies
This calculation is so much smaller then what
I got. Could I be right?
