Infrared light, and the range of light beyond the Electromagnetic Spectrum

For such a long time, there's been speculation that there could be at least one extra spatial dimension, except for time. Gravitational waves could change that: because what we think of as the "fourth dimension" could actually be the third dimension seen in a light that could reveal an entire new aspect on reality. But gravitational waves are like the riffs in dried up mud, and we are essentially in the mud, trying to study things that can be too futuristic for us but still detectable by modern technology! Radio waves are generally thought of as the end of the electromagnetic spectrum, at about one kilometer or one and a half miles long, but true electromagnetic radiation is composed of even longer wavelengths, those emitted by electronic devices. Then there are gravitational waves, which we have uncovered, and might actually use more practically for astronomy some day. In theory, humans can't even see Infrared light, but if you create Infrared glasses in a way as to block out stray light from entering, you could after a long enough time adapt your vision to be able to see the Infrared light: I don't recommend this, even though IR isn't dangerous like Ultraviolet light, as the refraction of Infrared light differs from that of usual light that we see. Infrared light needs to be focused more closely than visible light, so after a while of observation in Infrared light, your eyesight will probably adjust well enough so to become shortsighted in visible light!
