    How to detect EM waves of wavelength above 10 exp +10 meters?

    EM waves have no theoretical limits in their wavelengths, so that waves may have wavelengths less than 10 exp 10 -35 meters (Planck length) and greater than 10 exp +26 meters (length Our Universe) . If so, it would be possible to detect and record waves as small or as large? Theoretically...
