they knew that space was there because they can perceive it directly. it's literally right overhead all the time for their entire evolution. they know the faces of thousands, millions of stars, as soon as they tip their faces up. eridani is a name from two thousand years ago. all their stars have been named and known and watched and sung about for longer than any individual human civilization. they have always known the eridian star was there.

Over approximately 10 days, our Artemis II crew successfully completed a voyage around the Moon. They gave us stunning photos of the far side of the Moon, Earth, and a solar eclipse, along with inspirational messages, laughs, and even a few tears. Let's recap the Artemis II mission.

First step: fit check.

Artemis II astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen got suited up and had their spacesuits checked to make sure they were ready to go to space.

Shockingly, however, spending most of your time in close proximity to 500 pounds of liquid mercury is Not Great For One’s Health and tons of lighthouse keepers started to go crazy from the whole. Mercury poisoning thing. Hence why there are a lot of “haunted” lighthouses or wickies that lose it and maybe do a bit of manslaughter.

In a letter written on April 19, 1825, Augustin Fresnel proposed the use of mercury to reduce the friction in revolving lenses. His statement follows: “I propose to float our rotating devices, of the first order, in a bath of mercury, instead of placing them on rollers. This project won't present many difficulties; nevertheless, as I have not put it into execution, I won't require you to adopt it for your first lighthouse.”

Fresnel’s plan for mercury flotation was not put into practice until 1890 when Monsieur Leon Bourdelles, Chief Engineer of the French Lighthouse Service, designed and built a workable mercury flotation system. The mercury bath allowed the lens to operate in an almost frictionless environment and, additionally, allowed the speed of rotation to be dramatically increased.

It mattered for optics reasons.

Under less-than-ideal conditions, you can only see the beam when it’s pointed more or less directly at you. In-between beams you would not be able to see anything. One solution to this was to create multiple beams, and the lenses Mr Fresnel designed usually created 8 beams. But, even still, duration between flashes could be as long as one minute in the old mechanical roller systems.

The nearly frictionless operation of the Mercury suspension system allowed the lenses (large pieces of precisely ground glass weighing several hundred pounds in some cases) to rotate fast enough that they could be redesigned to create fewer (usually 3) beams. Fewer beams from a similar light source will be proportionally brighter, and the gains in speed were sufficient that duration between flashes could still be reduced to as little as 10 seconds.

This was a big upgrade. It didn’t just make the lighthouse signal faster, it allowed them to completely overhaul the lens and derive more visibility from a light source.

Nifty little language game here.

I can read back to 1500 with basically no difficulty

at 1400 I have to read slowly and carefully, but I can understand all of it save a couple words

at 1300 I can still comprehend most of it if I read slowly, but a much larger percentage of the words are unfamiliar to me, even with context

Warhammers in the European tradition were a response to advancements in plate armor technology: by the late Middle Ages, plate armor granted such significant protection to those lucky enough to lay their hands on a full suit that they posed an almost insurmountable threat to an unarmored fighter with armed with only a sword, club, or rudimentary spear. Late-medieval full plate is one of the purest symbols of power projection and power preservation in military history— in fiction, they mirror the status and power of the sword, stripped of the romantic and heroic ideals granted to the sword by its storied history.

140 MILLION YEARS BACK.

If you don't know how far that is, that's basically the start of the cretaceous. Let me simplify that for you even further. Chimpanzees and humans seperated, what, 5 or 6 million years ago?

This is basically like if humans could hybridise with THESE THINGS.

This is the sort of thing that should be impossible. They used those eggs to be ABSOLUTELY 100% SURE NOTHING WOULD HAPPEN.

And then THEY GOT FISH OUT OF IT.

Like. You can quite clearly understand why they didn't think anything would happen. WE ARE MORE RELATED TO BLUE WHALES THAN THESE THINGS.

THE AMERICAN PADDLEFISH AND THE STURGEON ARE SO COMPLETELY UNRELATED THAT THIS IS NOT PLAYING GOD. IF ANYTHING THIS IS AN ACT OF GOD.

THE SCIENTISTS HAD NO BLAME IN THIS BECAUSE NOTHING LIKE THIS HAD EVER HAPPENED BEFORE

THESE THINGS, FOR HYBRIDS, HAD A REALLY HIGH SURVIVAL RATING. LIKE 70% OF THEM SURVIVED.

To put that into perspective, getting a blue whale and a squirrel and trying to hybridise them is more sensible, and that wouldn't produce anything but getting you banned from science. Most animals that aren't plants can barely hybridise two degrees away from each other.

BUT THESE TWO ENTIRELY UNRELATED FISH create PERFECTLY HEALTHY HYBRIDS.

And this is a Russian Sturgeon:

(glances at fish)

before the sturddlefish, a purple squale would have seemed more likely- and since that's ridiculous and obviously no one would think that's possible except as a joke, that should speak to HOW impossible this situation seemed, and why they thought obviously this will be perfectly fine. If you took squirrel eggs (the gamete) and tried to use whale sperm to fertilize them, you could reasonably expect that to not work. That should be a good control. The eggs would definitely not actually be fertilized, and even if sperm somehow made it into the egg and some kind of development started, you would expect them to not make it to term and definitely not make a whole ass new animal that's perfectly fine actually.
