A Science Fiction Blog By Sean O'Brien Mon, 23 Aug 2010 02:27:53 +0000 http://wordpress.org/?v=2.9.2 en hourly 1 Have physicists discovered alien life? http://www.spacetimestories.com/uncategorized/have-physicists-discovered-alien-life/ http://www.spacetimestories.com/uncategorized/have-physicists-discovered-alien-life/#comments Sun, 13 Sep 2009 03:13:28 +0000 Sean http://www.spacetimestories.com/?p=412 Work published in 2008 from Israel claims detection of element #122.  If true the implications are stunning.  The only possible method of generating element 122 is by artificial nucleosynthesis, a technical feat beyond the capability of modern day humans.

While subsequent study may have disproven the theory this opens up a new method of proving the existence of aliens.  Even a single atom of element 122 (or higher) would be an artifact proving the existence of alien life…

Or time travel, it’s always possible that in the future human will make the element and then send back in time either coincidentally or as an actual component of the time machine.

Regular readers of my blog know that I propose there are no aliens anywhere and never have been.  So if element 122 is really discovered I claim it’s proof of time travel, not aliens.

This assumption seems very weak to me.  Why would every single species stop communicating by radio?  He also has an implicit assumption that colonization is rare or non-existent.

The real answer to the Fermi Paradox is much simpler:  the rate of evolution of sentient species is less than 1.0 per galaxy per 13 billion years.  We are the first and only intelligent species in the Milky Way, the odds that another will evolve before we have colonized the galaxy is nearly zero.  This theory perfectly fits the observed facts.
