only 70 galaxies....
I see what you mean, but...
Hmm.. 70 Galaxies only....

One of my former hobbies was astronomy, and I have a faint idea on how big one Galaxy is.
It is as far as Beyond imagination bigger than huge, so.. ha ha.
Did you know... Everyone agrees on this.. If you want to get somwhere in Our Space, you had to travel With the speed of light yes?
For the record, speed of light is 300.000Km pr second, or, 1080mil Km/H,and for you who have not switched over to metric values, it should be like 671mil mp/h. Get it? We agree this is pritty fast yes? (Even faster than Bill's truck, and even if his tires got a grip lol)
Now, it happens, you do have a Space ship that would do this speed. so, full throttle... or....
Problem is... G force.
Our physical body has some basic limitations, darn....
So, you fire up this fast Space ship, heading for some distance Galaxy. Preferrable one of the Close ones you have already processed. Just to take a look see around the neighbourhood.
Problem is, when putting the pedal Down on this vessel, you begin to feel Dizzy. Yes, Your body cannot take more than 9g's over a period, and that's 88m pr sec.
If some Math up this numbers, you will probably find that at full throttle, you would die from age before reaching such speeds.
Perhaps "some" decided we are not suitable to visit other galaxies?
So RHMash... be happy for the 70 galaxies you have reached so far
