I live in a very large city in Europe. I think the number of stars you can see is less than 20. Ground based pollution is horrible, I don't know how you can compare those two.

Maybe because large telescopes aren't in very large cities.

  100 years ago, lots of them were.

    Kind of.

In general, I'm fine with scientists needing to accommodate people more than they had to 100 years ago.

      That list of telescopes only goes back to 1932, and I studied astronomy at one of the institutions in question. As an example, why is this area named Observatory Hill? https://www.google.com/maps/place/Observatory+Hill,+Cambridge,+MA+02138,+USA/@42.3817392,-71.1344962,16z/data=!3m1!4b1!4m5!3m4!1s0x89e3776d1ec85c91:0xae23dbc6ed061fa6!8m2!3d42.382442!4d-71.1310717 https://www.google.com/maps/place/Observatory+Hill,+Cambridg... > In general, I'm fine with scie!tists needing to accommodate people more than they had to 100 years ago.

        You're right, not quite 100 years.

        ... it's named Observatory Hill, in the middle of Cambridge Massachusetts, quite near to downtown Boston, because it has an observatory that used to work great before light pollution.

If you go back 100 years, you could see stars great from the middle of your very large city in Europe. Then the lights came, one by one. This process is just starting with satellites. Can you see the connection now?
