Hi there! I love polka dots, jelly, and Greek mythology. And I would like to add that A Midsummer's Night Dream is the best play ever written. That is all.

Time Travel!

Did you know that it's possible to see things the way they were in the past? It is - but the only things you can see that way (as far as I know) are stars.
Because some of the stars we see are so far away, even light takes a long time to travel from there to here. Sometimes it takes up to thousands of years! (See this article on how we see if you don't remember - otherwise this post would seem confusing and unrealistic: http://www1.curriculum.edu.au/sciencepd/readings/ligh_how.htm#1) So that means that the stars we see are actually the way they looked a long time ago.
Amazing, huh?
