I amuse myself by asking odd questions and then working them out.
For instance, I asked myself: The sun is 93 million miles away from Earth. Light travels at 186,000 miles per second. Expressed in hours, how long does it take light from the sun to reach the Earth?
I will work it out and post the answer I get in comments below. However, I have to go breakfast, and knowing the lack of speed with which I work, it may not be the first comment. Post yours if you want to play along.
