The distances involved in space are very difficult for me to wrap my brain around. 10 million light years is a long way.

I feel the exact same way. I just don't 'get' astronomical measurements.

IIRC, a light year —as a distance measure— is how far light will travel in a year, in space. If you take light speed in a vacuum in miles per second(~186,000 miles per second), and multiply 186,000 miles by the number of seconds in a typical year (365 x 24 x 60 x 60 x 186,000) you get a number of miles light travels through space in one typical earth year.

I'm all right with the astronomical measurements...It's the astrological measurements used by obamao to compute the tax cuts that we should be thankful for that have me confused...
