“Imagination is more important than knowledge”
Albert Einstein
There is a website called “Journey by Starlight” which is said to be a blog for the curious and scientifically perplexed. It is basically about Einstein’s Theory of Relativity.
“This is the story of a great journey that started with a great thought. One day in 1895 a boy looked into a mirror and wondered what the universe would look like if he could travel on a beam of light. That sixteen year old boy was Albert Einstein and that one thought started him on the road to discover his Theory of Relativity. The great man has been reinvented as Albert 2.0 to come back and blog about a journey through space on a beam of light and explain the science behind everything from atoms, blackholes to global warming. The most recent posting is on this page. If you’ve just joined and want to start at the beginning use the index on the left. If you’re bored try these links below just for fun.”
It incorporates an Alien Contact Calculator which uses something known as “The Drake Equation.” The calculation at the moment shows that there are probably another 25 civilisations in the Galaxy.
Great site.
