the earth is actually a triangle

No <:PotatoFlatEarth:651630736712925195>

prove me wrong

If the sun circles us then the logical conclusion would be a ring of ice around us where the sun cant reach. So the known earth is a circle

but wouldnt the sun melt the ice

@Pewdielie yes to a certain point

Just as is observed

Let's debunk this one

how does flat earth account for 24 hour sunlight in the antarctic during the summer solstice?

@Citizen Z thanks for posting the Olbers Paradox meme! I had forgotten about that. back in grad school I was taking an advanced mathematics for physicists course and the prof (also head of our theoretical chemistry group) put this problem on one of our exams. When we discussed later, he didn't offer an explanation for why we don't see this in real life and just said "it's interesting, isn't it? with a little smile :). He was a devout Christian so perhaps he had a suspicion that something is wrong but didn't dare bring it up in class. I should contact him and discuss FE. He is one of the sharpest guys I've ever met.

Its because of redshift

no I think it's gravity

I don't see how gravity would cause that effect?

it sucks the light away so we can't see it

Yes its interesting.

wha?

🤣

😄

oh its a joke

sorry. we shouldn't make a joke of space.

that's NASAs job

Whats a joke?

we pay them $20 billion per year so we shouldn't do their work for them...

The explination for this paradox fyi is that light that travels long distances gets shifted to lower frequency, an effect called "redshift." This means that stars that are very far away emit below viable ranges.

right. millions and billions of "light years" away!

but there is cosmic background radiation at lower frequencies that is similar to what the paradox describes that you can detect with a large telescope

hmm....I think I'm sticking with gravity

pardon the pun 🙂

The solution to the Olbers paradox is that there are many things in between the stars and the Earth, like nebula which absorb nearly all visible light

i am stuck on probability hw

😠

ironically i have probability hw i should be doing rn

i get answer two different ways that both seem right but they both different

yuck

There is light everywhere in the universe in the form of the cosmic microwave background

u can post the question and i can try to help if u want

im not sure if i can
