OK but it’s pretty cool that the moon is just far enough and just the right size relative to Earth and the sun to give us all those rad eclipses.

EDIT: Also I tested and this burger is the same size as a Canadian one dollar coin.

I read somewhere that this phenomenon is so unlikely that if we ever need to represent our planet in an intergalactic context, the solar eclipse would be a good candidate for a symbol to put on a flag [citation needed]

[–] luciole 16 points 2 months ago (1 children)

I’m down and anyone who isn’t hasn’t seen a total eclipse yet. I saw my first one last year and by the time it finally came up I was starting to be a little fed up of hearing about it and slightly skeptical about how big of a deal it was. Then the day came, it got dark in a way my senses were not ready for and finally Totality happened, I saw the diamond ring with my own eyes and I lost my marbles at how fucking deeply existential this moment felt. 10/10 would watch again

[–] SomeoneElse@lemmy.ca 5 points 2 months ago

I’m in the UK so didn’t see the last one but during the previous one I found looking around at the darkness and observing how all the birds went quiet was a bigger deal than the actual eclipse of the sun. I mean that was still really cool, but the dark and stillness was uncanny.

[–] puttputt 7 points 2 months ago

Sorry, but a similar design is already taken by the planet where everyone's obsessed with The Ring

[–] deadbeef79000@lemmy.nz 3 points 2 months ago

Iain M. Banks wrote a book on that. Inversions I think.

[–] GreatTitEnthusiast@mander.xyz 8 points 2 months ago

Because the moon is moving away very slowly there will be a last total solar eclipse at some point. We're lucky to have such good ones currently

You mean a Loonie.

SMH.

[–] luciole 2 points 2 months ago (1 children)

You’re right I should use the scientific names for things in this community.

[–] Underwaterbob@lemm.ee 2 points 2 months ago

Accuracy is important. Precision, too. Don't mix them up!

That's just what CSA and NASA want you to think. /flerf

[–] jsomae@lemmy.ml 15 points 2 months ago (2 children)

actually the part that i am scratching my head at is the sevenfold brighter bit.

[–] MadLegoChemist@startrek.website 6 points 2 months ago (1 children)

I was curious about this too. From random web searching (Syfy.com), the sun is 200,000 times brighter than the moon in the visible light region of the electromagnetic spectrum.

[–] jsomae@lemmy.ml 3 points 2 months ago (1 children)

I know human perception is logarithmic. I'm interested why it was thought it was 7x brighter. "Sevenfold as the seven days in one" it seems?

[–] MadLegoChemist@startrek.website 1 points 2 months ago

I didn’t know about logarithmic perception, that’s interesting! I bet you’re right about 7x being chosen due to the significance of the number seven in the Bible.

[–] vithigar@lemmy.ca 2 points 2 months ago

I was surprised to see that they dug a verse from the Book of Enoch. It's not even considered to be canon within Christianity or Judaism.

[–] LibertyLizard@slrpnk.net 15 points 2 months ago (3 children)

Is flat earth still a thing? I haven’t been hearing as much about it lately but maybe people just stopped caring.

I do wonder how long a movement that can be easily disproven by literally anyone can sustain itself. I mean sure, the true believers will stay but if anyone can go out and confirm the roundness of the earth themselves it makes it a bit tough to keep people who are on the fence…

[–] scrubbles@poptalk.scrubbles.tech 21 points 2 months ago

I think the vast majority of promoters online were trolls, and the vast majority of followers were morons

[–] CosmicTurtle0@lemmy.dbzer0.com 12 points 2 months ago

You haven't heard as much from them because they are being drowned out by MAGAs. Though, TBF, the overlap between flat earthers and MAGAs is pretty large.

[–] Tlaloc_Temporal@lemmy.ca 7 points 2 months ago

There's actually a trip to Antarctica to see the midnight sun funded by globe earthers planned soon. Many flat earthers were invited, but most have chickened out and the rest are hedging their positions with "24 hour sun doesn't mean anything, even if we see it, it doesn't matter".

[–] Worx@lemmynsfw.com 15 points 2 months ago (2 children)

Americans are insane. I don't want to stereotype, but who the fuck needs a burger the size of a car?

[–] vrighter@discuss.tchncs.de 1 points 2 months ago

I had lots of cars the size of burgers though, when I was a little child

[–] Dyskolos@lemmy.zip 9 points 2 months ago

I'm actually still convinced that Flats are just trolling the whole world and pissing their pants from laughing when noone looks.

These things can't be truly real and serious. They can't. No. Nonono.

[–] xilliah 8 points 2 months ago

Fun fact as a game dev I had to write this code a couple of times where I project the 3d stuff into 2d like that so when you tap with your finger or click I can do proper distance checks in 2d (what's closest to the finger?), even though it feels and acts 3d.

[–] drolex@sopuli.xyz 7 points 2 months ago

I never remember which one is the burger eclipse and which the car eclipse

[–] FarceOfWill@infosec.pub 6 points 2 months ago

What is that? A car for ants?

[–] sundray@lemmus.org 5 points 2 months ago

Great, now I'm hungry for car : /

[–] madjo@feddit.nl 5 points 2 months ago* (last edited 2 months ago)

Flerfs can't understand scale, they can't understand 3d space, they can't understand distances, they can't understand pretty much anything. The world is scary for them, they deserve our pity AND scorn. If only they paid attention in school

Basically the father Ted skit with cows https://youtu.be/MMiKyfd6hA0

[–] cordlesslamp@lemmy.today 3 points 2 months ago (1 children)

how can I calculate the distance at which the sun filled my entire field of view?

[–] jjagaimo@lemmy.ca 5 points 2 months ago (2 children)

Theta = 1/2 human fov

r = radius of sun

[–] cordlesslamp@lemmy.today 3 points 2 months ago (1 children)

so simple (and not at all). Thanks.

[–] Tlaloc_Temporal@lemmy.ca 1 points 2 months ago (1 children)

d = r/sinΘ

Human FoV is about 210° with both eyes. Thus Θ is 105°.

The radius of the sun is 695,508 km.

Thus, d is 695,508/sin(105) → 720,043 km

720,043 - 695,508 = 24535 km away from the surface of the sun.

However, because the FoV is greater than 180°, this is actually below the surface of the sun, and any distance below the surface is enough to fill your vision.

To completely fill your field of view with the Sun, you'll need to take a Parker Bath and dip into the sun.

[–] cordlesslamp@lemmy.today 1 points 2 months ago (1 children)

I think 210° is when you moved your eyes to the limit at both sides. So let's say it's FOV when your eyes look straight forward and don't move.

[–] jjagaimo@lemmy.ca 2 points 2 months ago* (last edited 2 months ago)

The 210 is straight ahead horizontal FOV, i just didn't realize it was greater than 180°, which means it can technicaly never completely fill your peripheral vision. Your binocular vision with both eyes is around 115°. Vertical fov is only 135° though.

[–] MonkderVierte@lemmy.ml 2 points 2 months ago

I'm currently reading "The sword of Dawn" manwha. There, the planet is closer to a low luminosity star, making sunset/rise way bigger.
