Greetings to all ...
My wife and I got into a discussion last nite after looking at Mars through the telescope. A question arised and we were wondering if someone could answer it ... If a radio signal travels at the speed of light (186,200 miles per second), then how long would it take it to get to Mars - from Earth? 36,000,000 miles is a very long way for a radio signal to travel ![]() Thanks in advance! -- Phil |
