Okay, okay, but roll with me here…

A lesbian version of Good Omens, with this idiot as Aziraphale…

and this idiot as Crowley…

These idiots here, these perfect, perfect idiots

These ones, these idiots right here. They could definitely fork up an apocalypse and if you don’t believe me you have never seen their show and you should <=

why are cyberpunk tabletop things so obsessed with decency and personhood being tied to how many surgeries you haven’t had

“if you have a prosthetic it takes out a part of your soul” like thanks shadowrun

[rlyehtaxidermist]

in early cyberpunk, the point was more along the lines of “if we integrate technology into our bodies we risk becoming dependent upon the people and institutions who control that technology, who would then use that to enrich themselves at our expense”

unfortunately that was too anti-corporate for American mainstream culture so as cyberpunk moved out of its niche it became “uhhh it eats your soul I guess”

also think about crowley saving aziraphale throughout history and it’s just a thing that aziraphale allows to happen repeatedly and and crowley’s role on earth really runs a lot more toward the angel-saving business with a side of wiling than the other way around, except that when it really matters, the time it really matters, the end of the world, aziraphale won’t let him. aziraphale rejects him. crowley is begging aziraphale to let him save him and aziraphale says no, and crowley goes back again to beg again and aziraphale says no, and then crowley goes back a third time, full up with desperation because hell is here they are already here we have to go now, he gets to the bookshop to beg with aziraphale a third time, and the bookshop is on fire. aziraphale is gone. 

it’s not just that somebody killed his best friend. it’s that for the first time ever, crowley didn’t save aziraphale. it’s that hell came for them–crowley doesn’t know that heaven came too. crowley thinks aziraphale was killed by hell because of who and what crowley is, right after aziraphale forgives him for that. right after aziraphale refuses to let crowley save him from that. 

in that moment, somebody didn’t kill crowley’s best friend. crowley did.

Blinded by the Light

One of the common tools of amateur astronomers is a red light used to see charts and telescope settings. The idea behind the use of red light is to maintain dark adaption for nighttime viewing. While red lights can help in that respect, things are not quite that simple.

Dark adaption comes in two stages. The first is simply the due to the size of our iris. In bright light our iris closes more to let less light into our eyes, while in dark light it opens up to let in light. This shift can happen in a few seconds. You can experience it, for example, when you enter a house on a bright sunny day. For a few moments things look dark, but you’re eyes adjust pretty quickly.

Real dark adaption happens on a chemical level. Your retina detects light through what are known as rods and cones. The cones come in three types that are differently sensitive to wavelengths, which is how we’re able to detect colors. Rods are more numerous, and are much more sensitive to light. Since rods only come in one type, they aren’t able to give us information about color. Both rods and cones become “blind” to light if they are over exposed. You may have seen this effect when you stare at an image for a while, then look at a white wall or sheet of paper. The after-image you observe is due to the over exposed cones. The chemical reset for cones is fairly quick, so after a few minutes the after-image will fade. For rods, however, the chemical reset can take half an hour or more.

During daylight hours, your rods are over exposed, and so are less efficient. As light gets dimmer, a chemical change allows them to become even more sensitive, and your eyes become dark adapted. If you’ve ever been camping, you might have noticed that as dusk falls the green leaves will appear brighter. This is actually due to your rods becoming dark adapted. Rods are most sensitive at around 500 nanometers, which is in the green to cyan range of the spectrum. In the truly dim light of a dark starry night, your rods become highly sensitive, and the night sky comes alive.

So what does this have to do with red lights? It only takes a brief exposure to bright light for your rods to over expose. Once that happens, you have a half hour or more to regain dark sensitivity, which can seriously hamper your astronomy experience. Since rods are less sensitive to red light (below 650 nanometers) you can use a red light source to view things without ruining your night vision. However it has to be the right kind of red light. Simply taping a red filter over a flashlight isn’t a great solution. Cheap filters don’t block other colors very well, so a bright flashlight with a red filter can still ruin your evening. There are red LED lights and properly filtered red flashlights that are made for astronomical viewing, and these are much more useful. Even then, you don’t want your light source to be too bright.

Although red lights are most commonly used, another solution is to use a cyan-green light. Since this is the region where rods are most sensitive, that might seem counter intuitive, but it’s that sensitivity that makes it useful. Since rods are most sensitive in that color range, you can use a very dim light, and still see things. As long as the light is dim, it won’t over expose your eyes, and your night vision will be maintained.

The best method to preserve dark sensitivity is to simply not use any light source at all. Find a dark place under a dark sky, and simply watch the stars. If you’re patient, the sky will seem to gradually brighten and you’ll be amazed at what you can see.
