That says the surface of the water bends down

light bends up

That contradicts the first gif

Which seemed to have suggested that light bends down then up

an the other image explains that

That's a Sheeple gif! Been a while since I saw that.

🙂

Please explain I don't understand it

Refraction causes light to bend upwards

This is what I need explaining

Wait

Bend upwards as in

The claim is boats *appear* to disappear over the horizon, because of up curving refraction.

Wait wait wait wait wait

Okay.

It's miserable how I cannot post an image to explain what I wanna know

Let me describe it

First: light travels down then up
Second: light travels forward then up
Third: light travels in a straight line with a downward component

Which one do you mean

Also, I do not understand refraction coefficient monitoring

you want reading material on REFRACTION being tested empirically?

Is it true that some flat earthers believe that Australia doesn't exist?

@Secrette yes. after laughing, we need to look at the proofs they have

and laugh again amirite

I've never met anyone who believes that Australia doesn't exist.

I heard it from somewhere, but I can't remember.

@Rigg5 what do you think about sunspots?

what are they?

in the FE model

@Sassy Undeniably this new kid @Geekgasm has questions about FE

@🎃Oakheart🎃 plz?

@Chris | Flat Earther yo

Whats up?

Why do you keep mass pinging everyone?

@burrito linguini

cy wanted to speak to you

he got banned tho
