I was just watching a TV show where a guy (private detective) is using a 70-200 F2.8 to take few pictures during night. of course being a tv show he can take blur free pictures of moving objects in near total darkness.

but it got me thinking that is it possible to make a lens that can achieve this for real.

Something like a 70-200 F1.0 (f1.2)or a 100-400mm F1.0 (F1.2)

my question is that is it technically (and financially) possible to create a lens like that ..as i am sure such a lens wont have issue selling itself.
