This misses the point, Dave. The refractive index of water is the refractive index of water, whether you're in it or not. The transition from water to air and vice versa exaggerates the effect but that doesn't mean that light isn't refracted just because you're in the water with the fish. It is...

Broken clocks Yeah, except there's no comparison between the two! It's equivalent to comparing the arguments for the existence of DNA (something you have no way of confirming first hand) and the existence of Sasquatch. People who try to convince others that Sasquatch exists are lunatics...

David, Do some real research of your own. Go HERE and HERE and experiment with it. Plug in whatever numbers you want and see if you can make a flat Earth work. Hint: Don't make the mistake of only doing calculations from the surface of a flat earth. Do calculation as though the 90° angle is...

The Pythagorean Theorem has only to do with right triangles. That is, triangles with a 90° angle in it. It basic means that since you know that one angle is 90° then all you need to know is either the length of two sides or the length of one side and the angle of one of the other two corners and...

I appreciate that, Dave. I really do. I like you as well. That's the only reason I keep pressing this. Are you sure you understand it? Because the argument isn't for a globed Earth. It does not prove that the Earth is round, it proves that the Earth cannot be flat. Do you understand the...

What? You have to study the Pythagorean Theorem? You didn't go to high school? You can't pull up and read a Wikipedia article? What's their to study? I spelled it all out for you! If this angle is X and that side is Y then there's exactly one possible value for every other aspect of a right...

I knew you were going to say something stupid like this. You're hopeless. I doubt it. With no more intelligence and discernment than you've shown in this thread, I don't believe you for a minute. Do me a favor, unless and until you drop this flat earth stupidity, don't take my side on this...

David, Here's another bit of Pythagorean Theorum that disproves a flat Earth... This time let's assume that the distances on Earth as reported by Google Earth are accurate but that the Earth is flat. To make the numbers easy, lets assume a two locations on the equator on an equinox. And...

Then the Earth cannot be flat.... The last few days I've been playing around with some math and thought I'd post some of it here to see if it might move some of the flat earthers maybe an inch or two back toward reality... Let's put some of the sunset images we've taken to good use and see...

It wasn't intended to be. Would you watch a video that claims to prove the Paul was not an apostle? If so, you'd be wasting your time just as I would be wasting my time watching a single second of another flat earth video. I haven't watched any for months nor will I. I've told you this many...

David, Do you deny the validity of the Pythagorean Theorem?

Just go outside and take your own photos David! These Youtubers are liars.

Probably not.

There was a database error that kept happening the last couple of days whenever I'd post something. Then the site was down for maintenance and when it came back, the last couple of days worth of posts were gone. Oh well! Where were we?

We seem to have lost several posts! :confused:

Welcome back Dave, The following is a repost of an argument I made while you were gone after several of us had taken near simultaneous photos of the Sun's position above the horizon from our various locations. I'd love it if you'd take a look... The last few days I've been playing around with...

Now that's a cool series of photos!

I agree. I hear people criticize wikipedia all the time as though its just 85% crap but I've never found anything there that was anything other than informative and basically dead on. That's not to say that there isn't plenty of stuff that's probably bad but that's true of pretty much anything.

Precisely!

Well, I'm still stuck on the right triangle math stuff. Check this out... Patrick brought up the size of the Sun. In the context he was bringing it up in, it's completely irrelevant because the angles involved are all calculated from the point in the center of the Sun, regardless of how big it...
