ORC’s have measurable size.
Heights and widths of identical ORC’s at distances D and 2D should vary linearly (similar triangles).
If the inverse square law applied, then the ORC at distance 2D should be one quarter as luminous.
An accurate telescopic photo of the farther ORC would then be twice as far based on lengths and four times as far based on luminosity.
Wherein lies the error giving rise to this contradiction?
Maybe odd radio circles have near field and far field regions? Conventional antennas do. Also there might be some dBi gain (decibels relative to isotropic). For instance if a dipole emitted one ORC at an antenna pattern maximum relative to us, and another, nearer ORC was emitted near a null in the pattern, it would confound the inverse square expectation. ORCs don't have to come from dipoles for this to apply; any anisotropic source will do.
