As an example, steel before 1940s didn’t have minuscule traces of atmospheric radiation in it.
Research conducted after the atmosphere had increased radiation would be different to research conducted after, in that vein.
Scavenging WW1 wrecks for non-contaminated steel for use in things like medical equipment is still ongoing, as an example.
Time can certainly change the answer to a question without any input from the individual user.
If it ‘can’, it can also ‘cannot’. The idiom refers to doing things where time changing is irrelevant.
