How Far Are The Nearest Stars?

When this guy goes on his road trip, the first thing I thought was that it looked like Salt Lake City.

Speaking of Idaho, I took one trip to the relatively small town of Pocatello to play in a chess tournament.  It was 172 miles away.  I love Salt Lake City, but it is hundreds of miles away from other major cities.  Las Vegas is 420 miles away.  Denver is 520 miles, and so is Reno Nevada. Boise is 340 miles.

Drag racing

In a restaurant they had Drag Racing on a TV. The racer obtained 205 MPH in 6 seconds. I did some math and got 1.55 horizontal G forces, which is amazing. The net G force combined with the earth's gravity is close to 2.

It is my understanding that some electric vehicles can do better.


Best wishes,

Range of human radio broadcast.

Not the square, but the blue dot. 

I have heard that our radio broadcasts are too weak to extend even that far.

This is about three times the diameter of "Known Space", which is the area explored by humans in a fictional series of great science fiction novels by Larry Niven and others.  https://en.wikipedia.org/wiki/Known_Space  However, at least five different advanced species exist in "Known Space."

My point is that you could have a vast empire just in the area of the blue dot.

BTW, our galaxy has so much mass that there are a couple of smaller galaxies that orbit it in the same way planets orbit the sun.
