What you probably don’t realize is that there is a super-massive black hole smack dab in the center of our Milky Way galaxy. By super massive I mean around 4 Million Solar masses in the case of the Milky Way; but black holes can be orders of magnitude larger, even Billions of Solar Masses. Gulp! Not only that there are super-massive black holes in the center of many, if not most, galaxies in the universe. By the way, the $60 phone call has been performed a great many times over distances as long as 10,000 miles which, if my math is correct, is almost half-way around the world. Obviously the operating mechanism - the “force” as you say - is independent of distance. Oh, my! 😬
Kip Thorne of Gravity Wave fame had to correct Carl Sagan’s idea in his book Contact that was to use a black hole to transport Ellie to the very distant planet in Vega. Obviously that wouldn’t work too well. So Carl Sagan used Kip Thorne’s suggestion of a worm hole.
