On June 16, 1995, Robert Nemiroff ( MTU ) and Jerry Bonnell ( UMCP ) posted the first Astronomy Picture of the Day . The site received 14 page views that day. The breathtaking beauty and didactic efforts of the APOD ’s daily posts have earned it global renown, and the site now receives over one million page views each day. From 14 to a million hits: Learn about the site first-hand from co-founder Robert Nemiroff in this telling Q&A, and don't forget to " Discover the cosmos! " Q. How did you and Jerry first come up with the idea for APOD? A. In 1995 Jerry and I shared an office at NASA's Goddard Space Flight Center and were watching the web develop. We would contemplate how we could contribute and brainstormed several ideas. The Astronomy Picture of the Day (APOD) was one of those ideas. This idea played off an underlying concern that astronomy images were sometimes being circulated as email attachments without people knowing what was being pictured.

They found no evidence that this fantastical form of travel exists. Time travel into the future is physically possible: Einstein's theory of special relativity predicts that the time between two events is slower for faster-moving objects. This has been experimentally proven by measuring clocks on commercial planes. But time travel into the past is trickier. Although many scientists have proposed the possibility of time travel into the past using the equations and concepts of Einstein's subsequent theory of general relativity, few scientists have conducted experiments to test these theories.
