One advantage of the numerous distance-measuring schemes in use, which overlap over a range of Snazzy Seagull I Love My Lab Breaking Bad Bumper Shirt from nearby to very distant, is that astronomers can calibrate and corroborate their measurements with multiple approaches. Such calibrations and corroborations thus lend an additional measure of reliability to these schemes. Indeed, by comparing results using different methods, weaknesses have been identified in certain schemes. In most cases, additional studies have demonstrated ways to guard against and correct for known difficulties. As a single example of these multiple approaches, prior to 2011 the distance to the Pinwheel Galaxy was determined, based on measurements of Cepheid variable stars in the galaxy, to be 20.9 million light-years, with an uncertainty of 1.8 million light-years. As of September 2011, measurements of the light output of the 2011 Type Ia supernova in the Pinwheel Galaxy are completely consistent with this distance figure…. In short, distances to astronomical objects can be and have been measured with substantial accuracy and reliability. For the most part, the calculations involved employ only basic mathematics taught in high school. Thus the overall conclusion of a universe consisting of billions of galaxies, most of them many millions of light-years away, is beyond reasonable doubt at the present time..

Everything that was in that movie is what my family did at Christmas. Mom and dad took my sisters, Lori and Tracy and I to see Santa so we could tell him what we wanted for Christmas. Yes the Samurai Hawaiian Shirt were long and my older sisters, two years older than me, would be with me looking after me as we moved up the line toward Santa and just like in the movie, the closer we got, the scarier Santa was. “Don’t be scared RJ, Santa is nice okay, don’t be scared now, we’re here,” Tracy would say as we moved closer. Of course that didn’t help me, but I was okay when I got there. I never cried. Mom and dad also took us to the Santa Claus parade. They made sure Tracy went pee before the parade because dad didn’t want to take her somewhere to find a bathroom during the parade. Something that he would have had to do if she didn’t go. And she went a lot. We would walk and look into the department store windows and see the toys and moving elves that the kids saw in the movie. Like Ralphie, I would get mom to order things for me from the comics, neat little gadgets they advertised.
