PROGRAM

 

Tom introduced Charles Forbes Gammie, Professor of Astrophysics, the University of Illinois.   Professor Gammie received his undergraduate degree in Math from Yale and his PhD in Astrophysics from Princeton.   His research involves black holes and planet formation.

 

Gammie said that scientists can precisely date the age of the sun, planets and moon.   The Big Bang occurred 13.7 billion years ago.  Our solar system formed 4,576 billion years ago.   

 

The Apollo Moon missions changed scientists thinking about how the earth’s moon was formed.   Geologist and former US Senator Harrison Schmidt went to the moon and collected moon rocks.    Geologists found that the rocks from the moon have a similar isotopic fingerprint as those on the earth, but the moon doesn’t have the iron found on earth.

 

The current leading theory about the formation of the moon is that 4.5 billion years ago, the earth was struck by another planet.   Professor Gammie showed a computer simulation of this event.  Within a few hours, the other planet would have been destroyed, leaving a ring of vaporized rock around ours.   Eventually, the ring would have cooled, condensed and solidified into our moon.  The moon would have been about 3 earth radii from the earth.  The earth’s tides have pushed it further out by 3.8 centimeters per year.  It is now 60 earth radii from our planet.

 

Professor Gammie also talked about mile long lava tubes found on the moon.  The moon has no atmosphere but the lave tubes might one day provide a habitable shelter for humans
