I Just Remembered I Have Some Aurora Borealis Stuff I Could Share - Tumblr Posts

It definitely made sense, a lot of it, actually. I've seen these graphs before, and they finally make sense!

About history mixed with astronomy, Weird Sky Stuff™️ had been considered bad omen until at least early 19th century. At least in Poland. It appears even in The Gem Of Polish Literature "Pan Tadeusz" by Adam Mickiewicz ('Pan' in Polish means Mister though it's used more like Sie in German. I think. I passed German on cheating and the fact that nobody, including teacher, really cared. Anyway, if you did the most grammatically accurate translation of the sentence "Panie Prezydencie co Pan o tym sądzi?" meaning "Mister President, what do you think about it?" it'd be "Mister President, what does Mister think about it?". Sorry for the long rant, I love my language). Anyway, in this long ass poem, there is mention of the comet appearing in the sky and it being viewed by the local population as a sign that something bad is about to happen. In the book, it's about a year before Napoleon's campaign against Russia, (if I recall correctly, it was showed down my throat in school enough for me to not want to check it), and we know how it ended. Poles were generally on Napoleon's side since Russia was one of the three countries that took our independence, and Bonaparte promised to give it back. Apparently, it was kinda autobiographical of author. Though I think comet irl was blamed for something, I think it was some blight. Idk. Though I can recite first fifteen or so verses of it from memory, up to twenty-two with minor help. My family and friends can too, "Pan Taduesz" is a really big thing in Poland for a cottage core story with far less "fight for the fatherland" bs than usual.

Anyway, since it wasn’t really as spacey as it should be, I brought out my astro fun facts book, but none of the chapter titles sparked my interest (and all of them are pretty basic) so I'll rant about chances of meeting aliens.

When thinking about it, we need to consider few things.

What are that chances that there is other habitable planet?

What are the chances that life appears on such planet?

What are the chances that on this planet, there are species that created civilisation advanced enough to travel through space or at least send their own Voyagers?

Is this planet even in our observable universe?

I'll try answering these questions one by one

1.

I don't know the exact numbers for it, but when looking for habitable planets, few things come into consideration. Size of the star, it's brightness, how calm it is (idk how too explain it, it can't be roatating too fast or giving off too much radiation and stuff), how far the planet is from the star (it has to stay in the zone where temperatures allow it to have liquid water) and whether or not it's a stone planet (rocky planet? I'm not sure about English terminology). I watched series of YouTube videos explaining it once (they were made for the purpose of worlbuilding though) but I don’t remember almost anything from them so I can't give you numbers.

Also some may argue tha with sample size of one we can't really say what are the requirements for the planet to have life on it, so anyway numbers can be whatever

2.

For this one, I genuinely have no clue. Scientists aren't even sure how life came to be on Earth, I don't think anyone has any numbers on how likely it was to happen. Unlikely, I think.

You have to consider the age of the planet and the whole system when considering that, though. This is a reason why it's unlikely to find life around big, short-living stars.

3.

On Earth, it's 1/5 to 10 billion according to this site. Which is pretty cool, I think. We don't think about it often, but humanity is an evenement in the history of the world. There was only one species that created civilisation, one that started rebuilding the environment around it to suit its needs better, one that tamed fire and thunder, one that used riches from underground, one that explores deep seas despite not being able to breath underwater, one that flew without wings, one so full of wonder it reached the stars. And it took us hundreds of thousands of years to achieve it.

But we did, so there is always a chance that there is someone else who also managed.

4.

Who knows, but there are three ways two planets can answer that question, and I have crudely made pictures to explain it.

For the purpose of the explanation:

The size of the visible universe is dictated by from how far away light has gotten to us. It's getting bigger with every second. Obviously, for every planet size will be the same.

Anyway, the first relation we can have with alien civilisation is this:

We're actually in each other's visible universes! Just you wait until we detect each other and meet! Hopefully peacefully!

I'm of course, Oompa Loompa Planet has civilisation capable of sending their people to space!

The second way for it is:

Where we aren't in each other's visible universe but we share some stars. I personally find it pretty cool. Like "I look at the same stars as [insert some celebrity/other well known figure]" but more.

And mabe, we'll meet. It can take billions of years but maybe. If we escape before Sun dies, of course and if they do too, probably.

But there is also a third option:

We have nothing in common. It's kinda sad and we probably will never meet but who knows.

This is of course all pretty speculative but I find this topic interesting

I can look up some history meets astronomy stuff if you want. I'm really curious about what else you have up your sleeve

For reasons I'll not yet disclose

Also, if you want, share astro fun facts in reblogs and tags
