Is there a term for the fact that research is done only with the means available? It could also be placed on https://english.stackexchange.com/, but I feel it is more suitable here. So: Is there a term for the (trivial) fact that research is done only with the means available? 

For example a mineralogist won't study stones from the Moon if s/he doesn't have one. More specifically to my case: I am looking for a term that describes the problem of researchers who want to do something, but cannot do it by hand and not even by computers due to lack of suitable software/hardware (e.g. inverting very large matrices); and as a consequence they don't do it. (And in a verly last step, I want to find out whether there is research done about the consequences on science due to lacking software/hardware.) Is it simply called "lack of technology" or something similar?
In my university, people often call limitations as 'constraints'.

I have heard them saying: 

"resource constraints" - availability of computers and machines, people

"financial constraints" - Money

"space constraints" - Physical space (room), lab etc.
