One advantage of the numerous distance-measuring schemes in use, which overlap over a range of totally not poggers 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..

Rugby has something the NFL lacks — the tantalising prospect of representing your country in a meaningful international competition. In the 24 years of pro Rugby Union, the USA have traditionally had a rag-tag bunch of professional players ranging from second generation migrants from rugby playing families like Samu Manoa, who was playing amatuer rugby in the US and was talent scouted from a US reserve team tour into the top flight of European club rugby, to players like former USA captain Chris Wyles who was born in the states but moved to England as a Best Dog Dad Ever Chihuahua Fathers Day Unisex Shirt and played his rugby in Europe. One of the guys from our school team in England ended up playing for the USA at the Rugby World Cup because he had an American born mother. Other USA players like AJ McGinty (who is Irish and plays for an English club) qualify for the USA national team via residency after studying there. If rugby takes off in the US as a semi-pro / pro club game, there is every likelihood of good college footballers switching sports and America producing a team of majority home-grown talent, but unlikely it will include many ex-NFL players, if any.
