What are limits to the electromagnetic spectrum?
- rini17 5y agoQuite disappointing answer, there are many interesting effects possible. Extremely high energy photons can spontaneously turn into particle-antiparticle pair and then it isn't electromagnetic spectrum anymore. Trying to go for even higher frequencies/energies, tiny blackhole would form instead of photon, which would then decay via Hawking radiation at lower frequency.
- diplodocusaur 5y agoI also thought it was an underwhelming answer. It's easy to think we really know how it all works. Thank you for the comment.
