Posted on January 23, 2018 by justinrstevens

Some scientists called it an asteroid.  Others theorized that it was an alien spacecraft.  Still others cast it off as a mere “space cucumber.” This mysterious space rock known as Oumuamua (Hawaiian for “first messenger”) has captivated scientists since its discovery in mid-October of 2017.  Oumuamua was discovered in Hawaii, hence its awesome name.

http://en.wikipedia.org/wiki/Hubble_Space_Telescope#mediaviewer/File:NASA-HS201427a-HubbleUltraDeepField2014-20140603.jpg A topic that has really intrigued me is the speed of light and the time it takes for light to travel. The above image was taken by the Hubble Space telescope of galaxies billions of light years away. Some of these galaxies even extend back in time to only a few hundred million years of […] Continue reading →

Posted on March 16, 2014 by paanvaannd

  Is there other intelligent life in the universe? Mathematically speaking, there’s almost got to be some. In fact, it would be quite surprising to find out that there aren’t other intelligent life forms, let alone simple life.

Given the values of a number of variables, his equation may be used to estimate the number of species in the galaxy capable of interstellar communication. Drake’s proposed equation is as follows: N = R * fp * ne * fl […] Continue reading →
