10.10 Conclusion<quoted text>Do you all ever listen to what you say? You seem okay with the US being a gayocracy or athiocracy. How polarizing is it for the president of the US to come out and say that he supports same sex marriage when 44 states do not and neither does the constitution and the Supreme Court that he hates?
It appears that your personal beliefs hold back science, because all evidence supports an earth no older than 7,000 years.
According to astronomical observations, galaxies like our own experience about one supernova (a violently-exploding star) every 25 years. The gas and dust remnants from such explosions (like the Crab Nebula) expand outward rapidly and should remain visible for over a million years. Yet the nearby parts of our galaxy in which we could observe such gas and dust shells contain only about 200 supernova remnants. That number is consistent with only about 7,000 years worth of supernovas.
Let's briefly summarise how YECs such as Davies and Sarfati are correct and incorrect. First, in their favour, they are correct on:
The frequency of supernovae occurrence in our Galaxy
However, that's actually it. This is the only point in their favour. In contrast, they are completely incorrect about the following:
The number of actual, observable SNRs in our Galaxy.
The typical observable lifetime of SNRs.
The evolutionary timescales of SNRs.
The uniformity (or lack thereof) of SNR characteristics.
The presence of Radiative SNRs.
The difficulty of finding SNRs.
The distance to SNRs.
In others words, just about everything. In addition, the methodology that they use to calculate the numbers of SNRs they claim should be present is hopelessly wrong. They have also engaged in repeated misquotation, selective interpretation of the data and indeed, selective ignorance of data which disagrees with their conclusions. They are quick to assert that astronomers are confused and bewildered about the so-called "mystery of the missing supernova remnants". This however, is an assertion completely without foundation. There is no mystery. The YECs are making the mystery up themselves. They are completely wrong:
