If it were discovered that the redshift of spectral lines lyk ; 5 3 lr165b:hvcpgcoprlt 0u9)ntof galaxi ln(q (p3ej,lbes was due to something other than expansion, how might our view of the u(bqpne(l 3,ljniverse change? Would there be conflicting evidence? Discuss.
参考答案:
If the redshift was due to something besides expansion, then the Big Bang theory and the view of an expanding universe would be called into question, since the redshift is a major piece of evidence for the expanding universe. Also, the cosmic microwave background data would be conflicting evidence to this new data. Cosmic microwave background is seen as a confirmation of an expanding universe. Thus if there were some other explanation for the redshift, there might be two distinct schools of thought based on these two conflicting pieces of evidence.
