[ETL]

Why would anyone refer to a nonsense idea? “Theories” that don’t work are nothing but blather, no matter how many eggheads talk about them. We’re just talking about guesses based on guesses based on assumptions at this level anyhow.

Yet we are surrounded in our everyday lives by incredible technology that is based on such "nonsensical theories".

Er, we aren’t.

Pretty much any wild-*ss*d idea can be called a scientific "hypothesis".
If or when it gets strongly confirmed, then we promote it up to the rank of "theory".

But if, as sometimes happens, further evidence & new ideas strongly falsify a theory, then it's no longer called a "theory", it looses its stripes and gets busted back down to the rank of "hypothesis".
Indeed, after a certain point we don't even call it that, it's just a dumb-*ss*d idea, with a dishonorable discharge from legitimate science.

For an easy example, think "flat earth".

So, all that incredible technology surrounding us is based on confirmed theories, not just hypotheses, much less dumb-*ss*d ideas.
