I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.

I know bullets can be fast, but they are not exactly everyday life (at least in my life).

I included mass for obvious relativistic reasons.

You conveniently skipped over the "and are able to perceive" part

[–] Wolf314159@startrek.website 1 points 1 day ago (1 children)

No, I didn't. We can perceive electrons in various ways.

You can perceive high speed electrons in various ways, in your every day life?

Ok, that level of pedantry is my job

[–] Wolf314159@startrek.website 1 points 1 day ago (1 children)

That's not what pedantry means.

The effects of subatomic particles, even high speed ones, are apparent even if you are unaware of the cause.

Perceiving the effects isn't the same as perceiving the object, unless you take an extraordinarily pedantic definition of "perceive".

And considering an individual electron to be an object that you perceive is likewise not commonly an everyday occurrence, unless you take a likewise pedantic definition of "object".

And even the word "perceive" was my choice of word, describing specifically that I believed that the OP meant to exclude things like subatomic particles. So even in the end you're still trying to argue that I didn't really mean what I meant, due to word choice, which is also a very pedantic thing to do
