Cosmology Interest Group

CIG Page Image


The Cosmology Interest Group is a
sub group of the Lincoln Hills Astronomy
Meetings are in the form of a lecture or a
video series,
focusing on
some aspect of cosmology;
followed by a spirited discussion.  There is no need
to be proficient in math or physics formulas. 

We try to keep things as simple as
possible, so everyone can grasp the topic being
presented.  This is a fun group with lots very smart
members to answer just about any questions you

may have about the cosmos.
