TL;DR we found these chemicals present but with only one cherry picked exception we make no quantifiable claims of potential harm. That exception is lead, and we used the strictest standard we are aware of to describe the "dose", also note that we assume that the product is ingested to come to our conclusion. We also use weasel wording to avoid explicitly claiming that there are any regulatory or legal violations.

As someone who has worked in compliance testing for tightly controlled software platforms, things like this piss me off. These problems have known solutions.

Every use case we have is essentially “Here’s a block of text, extract something from it.” As a rule, if you ask GPT to give you the names of companies mentioned in a block of text, it will not give you a random company (unless there are no companies in the text – there’s that null hypothesis problem!). Make it two steps, first: Does this block of text mention a company? If no, good you've got your null result. If yes: Please list the names of companies in this block of text.

It really isn't though, at least not for long, as of mid 2023 there are publicly showcased compact lightweight prototypes with 240° FoV.

So, without reading, here are my uninformed thoughts on how I would do it:

You could probably figure out the distance by using a technique we use to figure out the distance to nearby stars, measuring the change in position in the sky relative to very far away stars. I think you'd only need to observe two stars to figure out the distance.

Could also use pulsar timing like gps signals to track the location of the Earth throughout its orbit.

Could also take measurements after launching a pair of space probes away from the earth.

If time counts as a dimension then there's 7-11.

Los of batteries are hmm in some circles purely by their dimensions. 18650s for example.

35mm (film)

9mm, 12ga, 22cal (firearms and munitions)

A pint (beer)

A 40 (beer again)

Eventually, there will be a telescope to be the last to set the record for the most distant galaxy observed, because cosmic expansion will make it impossible to observe things so distant. I sometimes like to imagine what it will be like in the far future when you can only observe things a billion ly away, or a few million.
