The Subtitles Do Not Help

Worth a shot BB but the subtitles do not help. Cyborg is his own enigma.

In the 1660s, Newton had shown that white light, when sent through a prism, can be broken up into the colors of the rainbow. In 1800, William Herschel had asked himself a simple question: What lies beyond the colors of the rainbow, which extend from red to violet? He took a prism, which created a rainbow in his lab, and placed a thermometer below the color red, where there was no color at all. Much to his surprise, the temperature of this blank area began to rise. In other words, there was a “color” below red that was invisible to the naked eye but contained energy. It was called infrared light.

Today, we realize that there is an entire spectrum of electromagnetic radiation, most of which is invisible, and each has a distinct wavelength. The wavelength of radio and TV, for example, is longer than that of visible light. The wavelength of the colors of the rainbow, in turn, is longer than that of ultraviolet and X-rays.

This also meant that the reality we see all around us is only the tiniest sliver of the complete EM spectrum, the smallest approximation of a much larger universe of EM colors.

Most of the “colors” of the EM spectrum, extending from radio to gamma rays, are invisible to our eyes. Our eyes can only see the tiniest sliver of the entire EM spectrum, due to the size of the cells in our retinas.

This is the black hole V4641 Sgr. 🌌🌌🌌

It's actually a binary pair - a black hole + an intermediate mass star! This duo was discovered after some violent x-ray bursts were seen and it produces the fastest energy jets known! 💥💥💥

Some animals can see more than we can. For example, bees can see ultraviolet light, which is invisible to us but essential for them to find the sun even on a cloudy day. Since flowers evolved their gorgeous colors in order to attract insects like bees to pollinate them, this means that flowers are often even more spectacular when viewed using UV light.

so I know that we figured out shrimp don’t see forbidden colors but remember only a small part of the em spectrum is visible so there are probably still forbidden colors

Radio Wave Propagation

EM waves are cobination of Electric and Magnetic waves. Propagation means how radio waves travel from one point to another point on the earth through free-space. Free space can refer to atmosphere or the air. Electromagnetic Waves (EM waves) are produced when the electrons in a conductor (i.e. antenna wire) are made to oscillate back and forth. These waves radiate outwards from the source at the…
