I like the bug facts, learning stuff is cool

HELL YEAH. I love science :D

Solar Eclipse, 8th April of 2024

Credit to NASA 💜

It was so beautiful.

[housecow]

i cannot give details bc. doxxing. but y’all i just had a defining moment for my research!!! the moment im back in TX i will feast in honor of it :3

[iknkeli]

drew this on my math book 🙌🙌

[ices-casket]

Hanging out with my friend and her brother was drawing with chalk, so I thought why not and joined him. (He looks a little wonky 😵‍💫)

And the angle that my friend saw

Extra drawing under the cut

The angle makes his face look extra weird so I just cropped it but there was text

"You have to wear sunscreen."

I know I yap a lot, but OML, I saw an aerial performance and thought 'top gun au. Now.' I need to touch grass. I enjoyed the cosi installment tho (science <33 (Nilered/Blue NEEDS to post another video) (the helicopter flying overhead kept distracting me))

I LOVE THE GLOBE OF DEATH⁉️ LIKE MAV AND GOOSE AS RIDERS WITH CAROLE STANDING IN THE MIDDLE??? My friend got to go in it was so cool.

I shouldn't be posting this much, but I draw quite a bit (I might just draw a few things and put it all in one post idk)

Because I’m a science bitch with a degree in science bitch shit (it was math-physics), I’d like to just explain my issue with there being a perfect eclipse in all the Dragon Age: the Veilguard promo material. Which is that it doesn’t work.

Like an eclipse isn’t just a moon blocking out the sun, it’s a moon with the same relative size as a sun, perfectly aligning with the sun. Any old planet can have an eclipse, it’s very hard to have a perfect eclipse. Often times the moon and the sun do not have the time relative size, thus leading to them lining up, but it being a partial eclipse with what’s called an annulus or ‘ring of fire’. The eclipse we had back in April was a perfect eclipse, meaning that it did not have a ring of fire, and that you could look at it! Don’t look at a partial eclipse with an annulus, it may look like a total eclipse, but it’s not. You will get hurt.

Now the issue is that the Thedas moon can’t do that.

See these moons?

See this sun?

The moons shown are bigger, in fact far too big to do a total perfect eclipse. It would just be a total eclipse with the sun being blocked out. So, the Moon cannot be the solar eclipse moon. This is where the problems start.

So what about the second moon of Satina that’s never been depicted?

Well, first off, for the big moon to be that big, it must either be very very large, or very close (remember, relative size, large items look bigger, but so do close up items). Now if it’s a large moon, then Satina could be a moonmoon, it could be hiding, we could be looking at a binary moon system, or Satina and the Moon could be far apart not affect each other. In that final case though, it does mean you should have more eclipses, so I suspect it’s not that.

So that leaves us with the others. Now, in order:

I’m just guessing it’s not a moonmoon. I would love it to be a moonmoon. But I don’t think it is. Mostly because no one cares about moonmoons except me and other people who find the name hilarious. Also that would make Satina not a moon of Thedas, but a moon of the Moon.

The moon isn’t hiding. I love the idea of a hiding moon, but it means that thw two moons have to have the same orbital speed. Or, the mass/orbital radius (distance from planet to moon) ratio has to be the same for both. But that’s not possible. Let’s say the Moon mass is 1 and it’s radius is 1. Then the mass/radius ratio is 1. Okay, so we take the second moon and make it small, let’s say half the size of the Moon, then the radius has to be 0.5. And sight lines are more or less a linear relationship, so that would mean the relative size of both moons would be the same. Now while he’s, this could be the case, BioWare’s also made it clear Satina is the smaller moon. So this doesn’t work.

Binary moon system. Honestly this would be two giant moons orbiting each other and is just a large moonmoon then. No I will not be explaining the physics of this. But it’s functionally that small things don’t actually orbit large things, small and large things orbit around the center of mass of their system, which just so happens to generally be in the center of the larger object.

The final one honestly could work! Honestly this is the most probable. That the Moon is big and close, and that Satina is much further away. Now, there does become an issue of Satina needing to be fairly large to do that, and at that point Satina and the Moon would gravitationally affect each other. But there’s probably a gravitational sweet spot where that’s not the case. However I’m not doing the math.

So what if the moon is just super close? Well… it would still be pretty big actually. Considering it takes up so much of the sight line, even if it’s super close, that’s large as shit. Furthermore, it’s a sphere, and thus it must be Of A Certain Size. The smallest spherical object in our solar system is still ~400km in diameter. However most spherical moons do tend to be bigger than this. Our moon is around 3400km in diameter, though it is unusually large.

As a final note, I do suspect that it’s just the 4th one of these, combined with Satina having phases, as the Moon is always a full moon, yet art in Thedas depicts phases. Likely referencing Satina.

So, ultimately I’m still wondering why there is a perfect total eclipse in the trailer and art, why Thedas has and knows about these things. Also why the fuck doesn’t Thedas have more imperfect eclipses with their giant moon! That should be blocking out the sun semi regularly! It’s not even that hard! It’s giant, and earth has yearly eclipses, Thedas should be having so fucking many okay?

my theory of science as a field is that. you know those light box things we would use to trace pictures as kids? my theory is that the true nature of reality is this wild complex crazy complicated picture, and it’s covered by about 100 layers of paper and that’s what we can perceive. and science is us putting that on a light box and trying to trace it. and every time someone makes a new discovery it’s like peeling away one tiny layer of paper to make it easier for the next person to trace.

Something that really stuck with me my first year of med school was learning that women are born with all of their eggs. They won't produce any more over the course of their life, and they grew with us whilst in the womb. That just tells me that everyone has kinda been with their mom since before their moms were even born. And I find that very sweet.

✨️ Supernova Remnant × Black Hole ✨️

SS433 is just that:

a black hole about ten times the mass of our sun & it's devouring the remnants of a large nearby star. [Njoom].

In a single year, it steals the equivalent of about 30 times the mass of Earth of material, which makes it the greediest black hole known in our galaxy!

It’s even stealing more material than it can consume.

Some of the excess stellar material gets blown off the disk & forms two hemispheres on opposite sides of the disk.

Within each one is a cone-shaped void that opens up into space. These are the cones that corral the high-energy X-ray light into beams (blue & purple) also called jets.

SS433 is located 18.000 light-years away from Earth & can be found in the Supernova Remnant Westerhout 50 or W50 in the constellation Aquila. It's also called Manatee Nebula.

Axolotls = Coolest Animal Ever

Axolotls are my new favorite animal. The fact they can regenerate any part of their body is incredible. The science behind why they can is equally fascinating. For the longest time ever, I’ve known I wanted to major in biology in college. I think understanding why the axolotl can regenerate and the potential ways that lead to future scientific breakthroughs for humans is my new passion.

Monster Fuckers are starting to reach positions of leadership in science, and I'm delighted to see it :p

(more seriously, gorgeous science and full of future possibilities!)

💖🌺If you get this, answer w/ three random facts about yourself and send it to the last seven blogs in your notifs. anon or not, doesn’t matter, let’s get to know the person behind the blog🌺💖

hi L!! thank you sm for this ask!! <33

1. i did musical theatre for about 6 years before switching to focus on film!! (shoutout to my fellow altos out there, musical theatre hates us fr but we’re in it together 🤞🏼)

2. i used to bake and decorate cakes for about a year during the pandemic to pay my bills :P very amateur if you will, but still fun + i needed money lol

3. i 🩷 science!! especially anthropology, i took so many anthro classes while i was in college idk why i didn’t minor in it 😭 but i am a big science nerd hehe

Me, about to answer a science-related question for my sister:

My mom: it’s because god made it that way
