I don't repeat work, see my signature and easily available zetetic works if you actually care about the numbers.
I don't see anything calculating where the focal point of diffracted light around the moon would be. I'll happily read the work elsewhere so you don't need to do it again, but it's customary to provide a footnote or citation of some sort so that readers can quickly find the source material your statement is based on.
Could you just point me to which of those threads has your calculations?
Happy to help
I'm sorry, but it's apparent from your google search that you don't understand the question. I'll try again.
In order for you hypothesis of a scorched Earth to be correct, the focal point of the diffracted solar light would have to be the exact distance between the Earth and the Moon. None of the works in your signature link have any calculations showing where the focal point of a lunar aragoscope would be. None of the links in your google search address where the focal point of a lunar aragoscope would be. Your initial post has no demonstration that the focal point would actually be at the correct distance to burn the Earth.
Since you're so fond of people doing their own work, I'm sure you wouldn't expect me to have to go through the actual process of calculating where the focal point would be to disprove your claim, seeing as it's entirely your responsibility to do the calculation supporting your currently baseless assertion.
Come back when you've done your homework.
