>I see nothing stupid with using quantum mechanics and nuclear science in this context.

why don't you?

Nothing in any of the examples show anything remotely related to either fields.

It's a brash leap to judgement to presume that something unexplained is using phenomena that we're well aware of -- and it's a brash leap to presume that given a video of flight dynamics that one can understand the technological progression of history required to do so.

Example : If it was an alien, how do we know they didn't purchase the technology? How do we know that another race didn't gift them something beyond their comprehension?

If we're making big leaping judgements given small amounts of evidence, why not write an entire history and lore for these aliens that must exist, given that we saw an unidentified aircraft?

It's ridiculous to jump to such lengths when a much more reliable and proven answer to the question of unidentified aircraft is : 'Military experiment'.
