Charles,
Thanks for your helpful suggestions. By the way, I find your web page links
concerning time dilation, dark matter, gravitational lensing, etc. quite fascinating.
I have since I was a teenager found the Lorenz transformation a source of
great interest in understanding the limits of space travel.
Cheers,
Robert
