Appearance of Moon Debunks Flat Earth with a 30-60-90 Triangle

The moon is at different elevations in distant cities while remaining the same size. If the Earth is a globe, that's because the ground is tilted different directions. If the Earth is flat, it's because the Moon is close while the size is distorted somehow.

In this video, I explain both ideas and show that if the Moon is an actual, physical object, then it's more rational to believe that the Earth is not flat.

I somehow forgot people believe the Earth is flat, thanks for reminding me.

[Swapnil]

"B- b- b- but it is indeed flat because that's what my ego dictates!"

[amensentis]

This is actually the most hardcore debunking of flat earth i have seen, provable by anyone with knowledge of like high school math, a telephone and a single friend.

Wow, I just realized this channel now has almost 500k subscribers. Congratulations professor!

This is one of my favorite teachers, yet he was never my teacher!

[liz.]

This is the most helpful and respectful debunking I have seen. I wish more people would take such a pure scientific approach to explain with out ridicule and address questions with the intent to inform.

Some more question to flat-earthers:
1. Why is flying from UK to NYC takes (consistently) ~40 min more than flying back??
2. If the Sun is a "bulb" then how come there are seasons??
3. If other planets are spheres, why would nature break its planetary consistency and make a flat anomaly?? Doesn't make sense..
4. And finally - if earth is flat, then why are we investing in discussion?? Instead, send a drone (equipped with camera) with enough fuel to Antarctica and see if falls from a cliff.. we have the technology i mean c'mon..

I'm pretty sure flat earthers cant understand what you said

Another compelling argument that can be made from the same pair of observations is that if the Moon were as close as flat earthers claim, observers in widely different locations would have different views of it (assuming the Moon is a sphere) or see it as circular only when overhead and an ellipse from everywhere else (if it were flat). Neither of those effects happens either.

He forgot to mention, in case earth is flat the moon not only should be twice bigger, but also look different since it's looked at different angle, for example different craters visible, different shadow aka moon phase, yet it looks the same.

I thought the moon was made of cheese. That's what some random 3D animation told me where a dog can prepare breakfast for its owner. Why wouldn't I believe it?

[Loifey]

It’s sad how someone already have disliked the video

[orangesheep]

Sent this to a flat earther

He blocked me on Twitter

[majabalaton]

Hello sir! I just followed your channel because your april fool videos. I thougt it wont be an 'april fool' video. I like geografy and astronomy and i really enjoyed this video. Thanks for the uploading!

[MrWeezer]

A terrific, clear, concise debunking. Kudos!

[ArcriLive]

I remember this guy from the prank school videos, but I've just realised he uploads actually interesting stuff.

Keep at it man, you're just getting started :)

[bobwill]

Question: I’m a flat earther, um, I mean, I’m in the lower of human IQ. Could you please dumb it down to my flat earth level of cognitive ability. Please note, I’m illiterate and will ignore anything you say, so, good luck.

[eugenemr]

Another thing he should've mentioned is, if photos of the Moon are taken simultaneously from 4 different location they all show the same features, how would this be possible if the Moon was close to Earth.

I was a flat earther before I watched this. Now I am a subscriber.
