The fact you can see light at a long distance can be explained by gravity. If i remember hs science lol, its that gravity can bend light.

LOL U! What is this 'gravity' of which u speak?

because

LOL. this post is dumber than the OP.

What's really funny to me about the lighthouse argument (I have spent a bit of time on the flat earther forum because it's endlessly entertaining to me, these people are further off the deep end than lizard people) is that it uses the exact same type of math that completely destroys the flat earth hypothesis.

D- troll

I only know RF from strategy forums from way back...... This is wtf

The Earth IS flat, as a first approximation, and as the most useful frame of reference for daily living.

Well, not EXACTLY flat... there are hills and stuff.

Also it's ridiculous to adopt heliocentrism as your model for daily life. Unless you are involved in launching things into space, it's perfectly fine to assume that the Sun revolves around the Earth. Otherwise you'd have to argue with everyone who said "Beautiful sunset", etc. etc.

As for OP, I have no idea what he's on about.

Open your mind.

Seems like a weak op because it just disproves RE without explaining why FE is the only alternative. Why not a square?

Ugh. Presumably you're just trolling, but the sad thing is that for every post modern hipster pretending to really be a flat-earther for the lols, there are a number of genuinely mentally ill people who should be getting help, and you're just encouraging their ravings.

Anyway, go to a beach. Watch a sail boat in the vicinity of the horizon. You will observe that the bottom of the boat disappears over the horizon before the mast. This is difficult to explain if you don't think the Earth is a spheroid. A pair of binoculars may help in your investigations.

The law of perspective is important to understand. It is that objects appear larger the closer they are and the smaller the farther away they are. Imagine a row of telephone poles down a road, they are all the same height but far off in the distance appear miniscule. This is part of the explanation of sunrises and sunsets which I'll cover more shortly but I want to mention first another reason how the law of perspective shows that the earth is flat.

On a cloudy day, even knowing that all clouds are on the relatively same plane/floor, they appear to meet the horizon. If you look directly above you see the floor of the cloud level above you. If the RE is true any observer between you and the horizon would look up and see a cloud level above them - however if the earth is curved then the clouds in the distance should appear tilted more and more the farther away they are.

This holds the same for hot air balloons and planes close to the horizon - have you ever seen the bottom of a hot air balloon as it should be clearly visible tilted to your perspective due to curvature. The bottom of the basket or cloud should appear to both you and the observer at the horizon.

Think above a skyscraper far off in the distance, it should not appear completely vertical but should be tilted away from you because its base is curved away. You will never see this because the earth is not round.

Now as for sunrises and sunsets it is due to the law of perspective that the sun 'drops' beyond the horizon. It goes farther away than you can see and eventually goes so far that its light no longer shines causing night. Why does the sun not get smaller as it gets farther away? Because the air is denser lower to the ground than high in the sky. You can see this by standing within a few yards of a street lamp, and noticing the size of the light; on going away to many times the distance, the light upon the atmosphere will appear considerably larger. This phenomenon may be noticed, to a greater or less degree, at all times; but when the air is moist and vapory it is more intense. It is evident that at sunrise, and at sunset, the sun's light must shine through a greater length of atmospheric air than at mid-day; besides which, the air near the earth is both more dense, and holds more watery particles in solution, than the higher strata through which the sun shines at noonday; and hence the light must be dilated or magnified, as well as modified in color.

I was awaiting someone to bring this up as it is the classic 'proof' of a round earth. The simple fact is it is a limitation of vision. If you watched the boat disappear then pulled out your binoculars you would still see the boat, it didnt disappear your vision wasnt capable of defining it anymore. If it disappear from your binoculars and you pulled out a telescope you would be able to see it again. This is a simple thing to test rather than accept what you've always been told.

And now you're gonna do the thing all FEers do where they pretend trig doesn't exist and ignore any arguments about it

You didnt address the fact that the bottom of the boat becomes non-visible(and replaced with visible water) before the top of the boat.

Yeah, you're pretending I said something else. I didn't say the boat disappeared, I said the bottom of the boat disappeared over the horizon and the mast was still visible. It doesn't make sense for the mast (which is smaller) to be visible while the hull (which is bigger) is not visible unless something is obscuring the hull.

The issue isn't one of the boat, in its entirety, being visible or invisible due to distance, but rather the bottom of it not being visible while the top is, due to the curvature of the Earth.

If the earth is a flat disc, what's on the underneath side?

Your troll powers are weak, by the way OP. The correct flat-earth answer to my objection is just to claim that what I say is not true, and request pics as proof, and then when I show you pics claim they are faked.

I read up on this once. It's so funny. Some people think that the disc edges are really tall ice walls manned by assassins that shoot down anyone that gets too close.

How do the seasons work conventionally? The sun shines its wonderful light upon earth and heats us up from over 90 million miles away. During the winter season RE is actually 2 million miles closer to the sun but because it is tilted it the sun is less effective and causes the earth to be colder. And in the summer the earth is not tilted away from the sun (but is 2 million miles farther away than in the winter) and causes it to be hotter. This is what the RE model presents, that the suns light covers over 90 million miles and because of a shift that causes it to travel a few thousand additional miles (even though it is 2million miles closer!) it makes the earth cold. Absurd.

Here is the explanation in the FE model.

You realize this isn't the explanation at all, right? Of course you do.

What causes the sun to jump orbits? Why is it in orbit at all? What is it orbiting?

Oh and the other great one was NASA just being a giant money laundering scheme for the flat earth Illuminati

So you believe that at cruising altitude and speed there is a sweet spot that keeps the plane locked into a level position because it moves into less dense air and falls then levels in the denser air?

Since math isnt wrong please explain the rivers, kansas, and Salt flat in Bolivia.

What is big and magnetic and in the north/center of the FE map?

What in the actual **** are you talking about?
