entity that is not limited by our perception

hi everyone,i'm just wondering if there is any entity such that it's magnitude can be increased without us having to increase space and we can continue to measure it with a given degree of accuracy(our limited perception does not get in the way),pls as many examples as possible.Thanks for any replies

If by entity you mean a physical quantity, things like voltage current can be increased without increased use of space (if that is what you mean by inrease space) and we can get accurate measurements too by use of proper instruments.

thanks for replying.spot on sir.But dont you think there is a maximum possible voltage(wont something burn out if voltage is too high?)?time matches the criterion however i'm looking for as many other examples of such quantities .Thanks again.

To display the measurement will take space. One can argue that there will always be a magnitude (of anything) that is impossible to measure simply because it takes too much space to display.
