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,
