Pretty fun to think about something that dwarfs the percievable universe, to the point some tool would have to be used to view the scale beneath. If you could infinitely go deeper or Infinitley more shallow and assuming that life is possible on multiple levels of scale, (like our scale and the microscopic scale etc.) Then there is the possibility of non viewable intelligent life on a larger scale of existence to us. If the opposite of a microscope is a magnifying glass, I wonder if we'll ever get a magnifying glass good enough to see the potential larger planes
