Welcome to Litsy!

All those nagging questions you have about the universe are answered here, like Is there a dark side to the Moon? What happens when a comet hits the sun? Do the Martian canals have any water in them? Is the moon hot inside? What would happen if the sun were to collide with a black hole? Mars has polar ice caps: could polar bears live on Mars? If I could go back to the time of the dinosaurs, would the sky look the same as it does today? and many more.
