Flat Earth General / my flat earth challenge!
« on: October 24, 2016, 06:08:43 PM »
In light of recent events, I wanted to make an example of a good, honest chalenge. So here it is:

I challenge anybody willing to participate to create a flat Earth model that features a sun that sets and rises in a way that matches what is observed in reality.

You may ignore any other constrains pertaining to a flat Earth such as distances, constellations, etc. The only constrains are that the earth must be flat, and the sun must rise and set in a way correctly in all locations.

Anybody who does not wish to participate in the challenge may choose to help me judge entries. I will take input and feedback from all participating sub-judges and decide if the entry completes the challenge.

The first successful completer of my challenge may request anything for me to draw in Microsoft paint. I will make the image to the best of my ability, and they may then use the image for their signature.

If you have questions or concerns, please ask.

Flat Earth Debate / Daytime and Nighttime doesn't match a spotlight sun.
« on: October 23, 2016, 05:04:09 PM »
I am basing this on the current most widely accepted flat earth model, the one found on the wiki. The map is this:


The theory states that the sun acts as a spotlight, illuminating a circle of area on the flat earth while moving across it.


However, this only matches summer day-night cycles. For example, during the spring and autumn equinox, at some point, the day-night on earth would have to look like this:



And even worse, during the winter solstace, the day-night would look like this:



A simple spotlight could not make these paterns, so the spotlight theory of the sun simply does not work.

Flat Earth Debate / accurate firmula for height hidden behind curcature?
« on: October 14, 2016, 08:56:26 PM »
I have seen flat earthers use an 8inch per mile sort of formula slot, but this does not take into account several variables, the most important being the height of the observer. Does anybody have a formula that takes this into account? If not, with a bit of work, I could probably come up with one. But I want to know if someone has done this already.

Technology, Science & Alt Science / Space X's plan to get a colony on mars.
« on: September 28, 2016, 02:28:19 PM »
So space X recently announced their grand plan for getting humans to mars and setting up a permanent colony there. Their rocket would be the largest ever built and it will be completely reusable and able to send 100 humans at a time for around 200,000$ per ticket.

Here is a short animation of the transportation system:

And if you want to sit through an hour of Elon Musk talking (he is a very bad public speaker) and get more information, there is this video here: " class="bbc_link" target="_blank">video

Some details of the trip and statistics:

Booster stage:
42 Raptor engines.
Thrust: 130 MN (29,000,000 lbf)
300 tons to LEO if reusable.
550 tons to LEO if expendable.
Similar grid fins as Falcon 9. landing back on launch pad for re usability.

Interplanetary stage:
6 vacuum raptor engines
18 MN (4,020,000 lbf)
3 sea level raptor engines
9 MN (18,000,000 lbf)
crew capacity of 100.

Raptor engines: about the same size and composition as the Merlin engines, but with three times the chamber pressure and 3 times the thrust. Statistics:
Thrust (vac.)   3,285 kN (738,000 lbf)
Thrust (SL)   3,050 kN (690,000 lbf)
Chamber pressure   30 MPa (4,400 psi)
Isp (vac.)   361 s
Isp (SL)   334 s

Test firing:

Suggestions & Concerns / new sub board: forum games.
« on: September 24, 2016, 03:39:38 PM »
I was wondering if there could be a sub board inside complete nonsense, where forum games could go (such as the counting game) I think it would be a nice addition.

The Lounge / Fantasy Fracas (community story)
« on: September 23, 2016, 07:21:42 PM »
Haven't seen a community story on this site, but I have had plenty of experience doing this on another forum, so I thought I'd give it a go.

Here's how it works. This community together will create a story. I will write a few paragraphs, and end with the main character needing to make a decision or a perform an action. You guys then suggest to me the decisions  or actions that the character will make, where I will write another few paragraphs. You can decide to make your suggestions realistic, or completely ridiculous, whatever you want. There won't be any punishments for silly ideas, but please do make an attempt to advance the story.

Rules:
1. Absolutely no suggestions involving the flat or round earth during the story.  Just don't mention it. I hope you understand.

2. No suggestions involving supernatural things. Ita fine if you want to suggest an action that would have a ridiculously low probability of working, but make sure that it is technically possible to do.

3. No fighting.

4. No trolling.

5. Have fun

6. Now rules as needed.

Let's get started!


It was just past midnight. You had the late night watch on the castle walls. It had been completely routine up to this point. You just passed your fellow watchman, Carter, when your heart stopped. You heard a sound you hoped to never hear in your life, the sound of goblin war drums. You shout "SOUND THE ALARM" but halfway through, your voice gets drowned out by the horde of goblins all shouting Anthe same time. You look towards the woods, and sure enough, thousands of the foul creatures were charging across the lawn, and made it to the wall faster than you thought possible. You faintly hear castle alarm being raised, but you don't have time to pay attention towards it. Ladders started slamming into the wall you were standing on, and four goblins saw you alone on the wall, and engaged, while the rest went towards the gatehouse. Two of them had spears, while then others had short swords. All you had was a sword and a knife.

Flat Earth Debate / Inverted moon on flat earth is impossible
« on: August 30, 2016, 03:13:07 PM »
It is a well known phenomena that people living in the northern hemisphere see a moon that is flipped from what the southern hemisphere people see. In the northern hemisphere, the moon looks like this:


And in the Southern Hemisphere, it looks like this:



This is easily explained by a round earth:



Yet a flat earth cannot explain it. People living on the southern hemisphere would see different orientations depending on the part of the southern hemisphere they live in. Here is an image I made to illustrate:



There is a serious problem with the flat earth model. Either it needs to be corrected, or you need to accept that the earth is round.

Flat Earth General / How does the atmosphere stay in?
« on: August 30, 2016, 11:08:24 AM »
According to the wiki, the Ice wall is only 150 feet up. Yet scientific experiments (and airplanes) have confirmed that the atmosphere extends much higher than 150 feet, but decreases with altitude.

Since the atmosphere density decreases with altitude, the atmosphere cannot be universal. Therefore, what is keeping the atmosphere from spilling over the ice wall?

Here is a graph of atmosperic density vs altitude:

Flat Earth General / Possible experiment to determine curvature.
« on: August 29, 2016, 09:26:05 AM »
I thought of this experiment, but I am not sure how well it would work, or if anybody has the proper tools.

Somebody with a good camera and a tripod should find a high elevation right next to a large body of water, and setup the camera perfectly level. Then take several pictures and see where the horizon is on the camera. On a flat earth, the horizon should be exactly at the mid-point of the field of view, but on a round earth, the horizon should be a couple arc-minutes down. I am not sure if anybody has camera's that could detect that, but here is the formula for how many degrees down the horizon should be based on how high off the ground you are (the higher the better):

cos-1(6371000/(6371000+h))=angle

h is measured in meters, and the angle is measured in degrees. At 1 meter up, the horizon should be 2 arc minutes down, but at 50 meters up, it should be about 13 arc minutes.

I am not a camera person, so I don't know if cameras that can see such a small angle exist, but if anybody does know, please say so.

Flat Earth General / E=mc^2 And other Einstein things.
« on: August 06, 2016, 05:29:19 PM »
Papa Legba thinks that E=mc^2 is unproven. But it actually has.

. . .

If it didn't exist, nuclear bombs would be impossible, and stars wouldn't shine.

This is a general Einstein thread I guess. For discussion.

Flat Earth General / I fixed every problem with the Flat Earth Theory
« on: July 29, 2016, 02:27:03 PM »
It was so simple, I'm surprised nobody thought of it before. I saw this on a web comic, and I thought: "since everybody knows that the earth is flat, but there are all sorts of mathmatical problems with it, there MUST be a particle like this that fixes all the problems! I give you, the flat earth fixion!

Here is the image I was referring to:

I need help getting all the problems with the flat earth theory put on this particle, then I will make an edited version of this image that explains everything.

Suggestions & Concerns / Should TotalLackey be banned
« on: July 25, 2016, 05:08:38 PM »
I think it is pretty obvious that TotalLackey is a PapaLegba alt, which violates rule 3:

. Multiple Accounts 
Do not create alternate accounts ('alts').

Flat Earth General / Flat Earth vs. Sphere earth poll
« on: July 22, 2016, 06:24:00 PM »
I looked a few pages back, but couldn't find a poll that was like this, so I was curious to see the thought demographics of this forum.

Simple question: Do you believe in a flat earth, spherical earth, or other (concave, dome, etc.)

If you chose other, please specify in a comment. Cheers!

Technology, Science & Alt Science / Round Earth Physics questions
« on: July 22, 2016, 06:18:50 PM »
I had a skeptimatic questions thread earlier, but I wanted to give flat earthers a chance to ask questions about how objects would work in round earth physics.

If you have any questions about what would happen in round-earth physics, post them here. I will try to answer, or somebody else will.

Flat Earth Debate / Questions for sceptimatic
« on: July 21, 2016, 07:44:46 AM »
I decided to make a thread exclusivity to try and find out how physics works in sceptimatic's mind. He hasn't bothered to answer in any other threads, and he told me to make a new thread, so here we are.

A few questions I have:

1. What is so special about the molecules in the atmosphere than no other molecules have. Why can we only get leverage off of the atmosphere, but not from any other object?

2. What are the laws of physics in your world?

Everybody else, chip in as well. I am sure this will require a team effort to figure out how he thinks physics works, but we may solve it yet!

EDIT: Septimatic has rage quit on this thread, so it is pretty clear that his own theory doesn't hold up. No use asking questions anymore.

Flat Earth General / domelike earth
« on: July 20, 2016, 12:48:57 PM »
I was wondering about how the sun could set on a flat earth, and how the southern stars were visible only to the southern "hemisphere" And I thought of a solution that partially works. The earth is a dome with the north pole at the top of the dome, and the Antarctica wall at the bottom edge of the dome. The sun and moon would circle around the dome at an altitude lower than the north pole, but higher than the Antarctica wall. This would explain sunsets and sunrises. This also makes southern "hemisphere" travel times closer to what we observe in reality, but not quite exact, some fine tuning would be necessary to know the exact angle of the dome.

The stars are in a rotating sphere around the dome earth, so the southern stars are only visible to the southern "hemisphere" While the Northern stars are below the horizon.

The only major problem I see is how we are stuck to the ground. Since the acceleration theory would mean southern "hemisphere" people would tumble off, there must be some attraction to the center of the dome. Maybe electromagnetism?

Please give feedback so I can perhaps see other problems and fine-tune the final angle of the dome so that it makes the most sense.
