1. Is it possible the existance of radiation that comes before the radio or beyond gamma waves or in other words, is the electromagnetic spectrum infinite?

...

2.

3. Somehow I think the upper limit would somehow be a factor of the speed of light, why..I don't know. It just seams like all my dreams and aspirations are always destroyed by that dead guy that says nothing can be faster then light. Nobody has yet to answer what color of light, but hey.

As far as below radio, sure it can be as slow as you want it. VLF is one of the ways subs can communicate under water. Normal radio waves get absorbed by the sea water a bit too easy. So they use very low frequency radio to communicate. I forget how low it is, but it's believe it's below our hearing range if I recall right. The antennas to pick it up are miles wide.

Welcome to the forum.

4. In theory it is infinite. The problem with low frequencies is that efficient antennae become huge.

Imagine a 1/4 way length antenna for say (ridiculous) 10Hz

v=f*wl

wl = 3 x10^8 / 10

wl = 3 x 10^7m

wl/4 = 7500000m or 7500km!!!

At frequencies above current radio frequencies the problem comes with parasitic reactive elements which effectively filter out the signals.

5. thank you for the insight in this topic.

6. Surely a wavelength less than the Planck length is impossible?

7. hmm...
as the infinite spectrum enters the other seven minute dimensions that exist all around us, could it adapt itself by applying the rules found in those dimensions in order to be compatible with plank’s length or other quantum sizes and in turn keeping the infinity property?

i don't get that plank constant or length, time etc is can someone please explain.
