Some Things You Just Have to Know

The 'fact' about the stars in the sky being so far way...  Is flat out incorrect!  These are Milky Way galaxy stars (where we live) and they aren't that far away.  Most stars live millions to many billions of years.  The furthest star you are going to see, with your eyes, are, at most, ~10000 light years distant.  That's not very long in star time!

The most stars you can see with your naked eye is about ten thousand of them...roughly the number of grains in a handful of sand.  This is only the smallest fraction of the number of stars that are.  The number of stars that are  is greater than all the grains of sand on all the beaches on earth.  - Carl Sagan

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates


The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates. Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states. It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).
