Which scientists...ours of theirs?  

I don't disagree, but suppose the level at which we could see it was a 
simulation was the Planck scale.  This is not entirely speculative, since the 
Planck scale is where a conflict between quantum mechanics and general 
relativity must manifest itself.  If the Simulators were only interested in how 
the world operates far above that level then maybe they were sloppy and just 
left potential inconsistencies in the simulation.  The program will crash when 
we do the right experiment to reveal it.  But that level is thirty orders of 
magnitude smaller than anything we can reach now.
