fun fact: the solar eclipse, as we experience it, is a uniquely Earthly phenomenon. we haven't seen another planet out there with exactly the right ratio of sizes and orbits so that a moon will block out a star but not its corona.
hey! this post is doing well! if you want to help out a trans woman who was fired for being trans and can't find work because the tech world has gone to shit, my venmo is $rachaelspooky
"It may be just serendipity that the sun is 400 times bigger than the moon but is also 400 times further away, meaning that both bodies appear the same size in the sky creating the perfect fit for the flaming sky show of a solar eclipse."
Jeffrey Kluger calls it the cold hard science warmed and redeemed by the fact that we are here to bear witness to it.
Maybe? Maybe something about this structure is conducive to life as we know it. Or maybe just really weird coincidence that seems significant because it happened to us. Not a big enough sample size to tell!
The specific configuration of the Earth, Moon, Sun triangle contributes greatly to how life evolved on Earth.
1: A single large satellite in an almost circular orbit stabilizes a planet's axis, contributing to stable conditions for solar radiation at any given point of the planet's surface.
2: The tides create a special transition zone between maritime and dry areas on shallow coasts, facilitating life's step towards the land.
Then: The sun is not a binary star, as most large stars in the galaxy seem to be. In a binary or trinary system, we wouldn't see stable orbits, as our planet has (the three body problem).
Furthermore: In terms of size, our sun is a class "G" star, which puts it in a very sweet spot, when it comes to stars' sizes:
Bigger stars burn faster, not giving billions of years for evolution.
Smaller stars live longer, but their physics is more unstable, creating huge electromagnetic outbursts, which would destroy complex molecules or could even blow away an entire atmosphere.
G-class stars are rather rare specimens.
Then, we have a massive planet like Jupiter in our solar system (far enough to not mingle with our planet's orbit), which acts like a gigantic hoover, catching comets and huge asteroids floating around.
Imagine, what could happen if we were hit by even bigger objects more often. One of these could have killed all life.
Then, during the forming phase of the solar system, Earth collided with another planet, Theia, forming the moon (which we already saw, is important), but also provided extra metal for the Earth's core, which gives our planet a stronger magnetic field than of any other of
I don't say, life couldn't evolve under other circumstances (we don't know, the universe is so incredibly big, we can not even really imagine its size), but the special conditions we find here, are truly quite rare, at least, as far as we know.
Our exploration of the universe and our galactic neighbourhood will remain fascinating as long as we do not kill ourselves with our own stupidity.
Regarding sizes, distances and other measurements, I can recommend watching
"Hidden Mathematics - Ancient Knowledge of Space, Time & Cosmic Cycles" with #RandallCarlson, which shows lots of so called "coincidences" - almost as if everything was designed on purpose.
Usually I'm a bit careful with pointing out such coincidences, because people tend to see "hidden plans" (i.e. religious or esoteric stuff) behind everything.
Jetzt fange ich gerade an zu gucken und er macht mich schon nervös, weil er es erstaunlich findet, weil er Zusammenhänge zwischen Einheiten, die auf den gleichen Primfaktoren aufbauen, findet.
So ist es nun mal im Dezimalsystem, wenn mindestens 2× der Primfaktor 3 auftritt (Einfach zu beweisen) und so sind diese Einheiten absichtlich konstruiert.
"The sum of angles in all these polygones again have the square sum of 9, for some strange reason".
Fuck nein! Nix "strange reason"
Die Innensumme der Winkel eines Dreiecks sind 2 rechte Winkel (Euklid!). Jedes Polygon lässt sich in Dreiecke zerlegen, also sind die Summen der Innenwinkel immer Vielfache rechter Winkel.
Und wenn der rechte Winkel in einer Einheit durch 9 teilbar ist, ist die Folgerung zwar cool, aber trivial.
