The discussion centers on the possibility of electromagnetic (EM) radiation existing outside the defined electromagnetic spectrum. Participants explore the implications of frequency limits and whether physical laws impose restrictions on the existence of radiation at subradio or supergamma frequencies.
Participants express disagreement regarding the interpretation of frequency limits and the definition of the EM spectrum. Some assert that the spectrum is bounded by definitions, while others argue for a more expansive view of frequency ranges.
There are unresolved questions about the nature of frequencies at the extremes of the EM spectrum and whether they relate to concepts like quantum energies or dark energies. The discussion reflects a lack of consensus on the implications of these definitions.
Vanadium 50 said:The EM spectrum encompasses all EM radiation, so by definition you cannot have EM radiation outside the EM spectrum.
No, it is just that there is no such thing as lower or higher frequencies. The EM spectrum goes from 0 to infinity, there is no frequency lower than 0 and no frequency higher than infinity.arjose said:Is there a physical law that creates this limitation or is it just a matter of technicality, where lower or higher frequencies are no longer defined as having electromagnetic nature?
