If you’ve seen the 2013 Superman reboot Man of Steel, you would have been introduced to the concept of terraforming. The remnants of the Kryptonian race wish […] Continue reading →

Alien Contact

Posted on April 27, 2015 by lukegchapman

The first time I heard about alien contact was actually from Scooby Doo and the Alien Invaders. I don’t know if anyone remembers that movie but there was a site in the movie where there were a ton of satellite dishes and they were receiving signals from “the great unknown.” I have always wondered what… Continue reading →

My New Outlook on Space

Posted on April 27, 2015 by robbyks

Space has always been a fascinating thing to me. In the past, I would often find myself getting lost on Wikipedia reading articles about the Big Bang or the future of the Sun.
