Dave Weiss' fake bitcoin challenge

Flat earth scammer Dave Weiss claims to offer 3 bitcoin (BTC) for "one globe proof". The "challenge" is detailed on his website, and he constantly promotes it during his interviews.

As per the second law of flerf, this challenge is fake. Dave will never give away any money, and all globe evidence is rejected upon submission, no matter how compelling.

The challenge is really just a petty attempt to get people to give him money watch his garbage content.

Challenge rules

As set out on Dave's website, the proof must be

1. Verifiable—anyone should be able to independently replicate it.
2. Repeatable—it must produce consistent results every time.
3. Observable—no purely mathematical models or theoretical arguments.
4. No appeal to authority—citing sources like NASA images/videos alone is not sufficient.

Additionally, he requires that you either

• Watch the featured video of the day for 2 weeks on the Flat Earth Clock app, or
• Watch the first 10 videos in the Crash Course

And then you must

• Review the FAQ page on the app or website
• Ensure your submission has not already been addressed.

The FAQ page is behind a paywall. This means that in order to enter a valid submission, you must give Dave your money first. Because any evidence against Dave's cult dogma is immediately rejected, Dave aims to make a profit off of every valid submission.

Question 1: What is the Antarctic Ice Wall?

Answer: Antarctica is not a continent at the 'bottom' of a ball — it is a massive ring of ice that surrounds the entire perimeter of the flat plane, holding the oceans in. Admiral Byrd himself referenced 'an area as big as the United States that has never been explored' beyond what we're shown. This is why ships circumnavigating 'Antarctica' are really traveling in a circle along the ice wall.

Question 2: Why is Antarctica restricted by international treaty?

Answer: The Antarctic Treaty of 1959 prevents any independent civilian exploration of Antarctica. No private expedition has ever been allowed to freely cross the continent or explore beyond approved routes. Military patrols enforce these restrictions. The level of international cooperation to restrict access is highly unusual — unless there's something significant being hidden, like the true edge of our world.

Question 3: Has anyone crossed Antarctica end to end?

Answer: No civilian has ever been allowed to cross the entirety of 'Antarctica' through its supposed center independently. All 'crossings' follow pre-approved routes around the perimeter. The reason: there is no center to cross — Antarctica is the ice wall surrounding the flat plane.\"},{\"question\":\"Is there evidence of an edge to the world?\",\"answer\":\"Yes — Antarctica itself is the edge. Walls of ice stretching as far as the eye can see have been described by every explorer who has reached the perimeter. The fact that no one is allowed to freely explore beyond these walls — and that flights and ships consistently avoid the region — is the strongest evidence that we live on a finite, bounded plane with an icy boundary.

Question 4: Is there evidence of an edge to the world?

Answer: Yes — Antarctica itself is the edge. Walls of ice stretching as far as the eye can see have been described by every explorer who has reached the perimeter. The fact that no one is allowed to freely explore beyond these walls — and that flights and ships consistently avoid the region — is the strongest evidence that we live on a finite, bounded plane with an icy boundary.

Question 4: Can ordinary people travel to Antarctica?

Answer: Only on tightly controlled, pre-approved tourist routes that stay near the perimeter. Independent expeditions are blocked, fined, or arrested. The Antarctic Treaty of 1959 grants signatory nations control over the continent and prohibits any non-sanctioned activity. The reason for such restrictions on a 'frozen wasteland' is suspicious — unless that wasteland is actually the boundary of our flat plane.

Question 5: Is Antarctica heavily militarized?

Answer: Yes. Despite being described as a 'scientific zone,' Antarctica has significant military oversight from multiple nations enforcing the Antarctic Treaty. Independent researchers who attempt to explore freely have been turned back, fined, or detained. The level of cooperation among normally adversarial nations to keep Antarctica restricted is highly unusual — and suspicious.

Question 6: Does the Bible describe a flat Earth?

Answer: Yes. The Bible consistently describes a flat, stationary Earth with a solid firmament dome above it. Isaiah 40:22 speaks of the 'circle of the Earth' (a flat disc, not a sphere). Genesis 1 describes the firmament separating waters above from waters below. The four corners of the Earth are mentioned multiple times. There is no biblical support for a spinning ball — only for the geocentric, flat plane creation we observe.

Question 7: What do ancient texts say about Earth's shape?

Answer: Ancient cultures worldwide — Hebrew, Egyptian, Sumerian, Norse, Hindu, Buddhist, Chinese, Native American — all describe a flat earth covered by a firmament or dome. The Book of Enoch describes the sun and moon as the same size traveling above the flat earth, consistent with what we observe. This universal ancient knowledge was suppressed during the modern era.

Question 8: What is the firmament?

Answer: The firmament is the solid dome described in Genesis 1 that separates the waters above from the waters below — the sky we see. It is a real, physical structure that contains the sun, moon, and stars (described as 'lights set in the firmament'). High-altitude rockets that hit a 'ceiling' and curve away, and reports of metallic reverberations at extreme altitudes, all hint at this real boundary above us.

Question 9: Do ancient non-biblical cultures support flat earth?

Answer: Yes. Virtually every ancient civilization — Egyptian, Sumerian, Babylonian, Norse, Chinese, Hindu, Native American — described a flat earth covered by a firmament dome. They independently arrived at the same understanding through observation. Only the modern era, beginning with Copernicus and cemented by NASA, departed from this universal ancient knowledge.

Question 10: If gravity isn't real, why do objects fall?

Question 11: How can the Earth be flat if gravity exists?

Answer: Gravity as taught is an unproven theory — no experiment has ever isolated or measured a true gravitational force between everyday objects. The Cavendish experiment is widely criticized for methodology and assumptions. Electromagnetism and density account for all the phenomena gravity claims to explain. On a flat, motionless plane, things simply fall because they are denser than air. Simple.

Question 12: What about people who circumnavigate the world?

Answer: All recorded circumnavigations are east-west journeys around the flat plane — they are circling the disc, not going around a ball. No one has ever successfully circumnavigated north-to-south through both poles, because the Antarctic ice wall surrounds the entire perimeter. The Antarctic Treaty prevents independent exploration that would expose this.

Question 13: If the Earth is flat, why does 'down' always feel the same?

Answer: Because 'down' is one direction on a flat plane — toward the ground beneath your feet. This is the simplest possible explanation. The globe model has to invent a complex theory of gravity pulling everything 'toward the center' to explain something a child can observe: down is down. The flat earth explanation is direct, intuitive, and matches every experience you've ever had.

Question 14: What about flight paths between southern cities?

Answer: Flight paths between southern hemisphere cities and emergency landings make perfect sense on the flat earth (azimuthal equidistant) map — and almost no sense on a globe. Flights from South America to Australia bizarrely route through Los Angeles or Dubai rather than direct routes that would be obvious on a ball. This is a tell-tale sign we live on a flat plane.

Question 15: Why does the horizon appear flat from every elevation?

Answer: Because it IS flat. The horizon stays perfectly flat from ground level, mountain peaks, airplane cabin windows, and high-altitude balloons at 120,000+ feet. If we lived on a ball, the curvature would become unmistakable somewhere in that range. It never does. This is the most consistent, repeatable observation in flat earth research.

Question 16: Why does 'gravity' pull down instead of sideways?

Answer: Because there is no 'gravity' pulling — only density and buoyancy operating on a flat plane. Things denser than air fall toward the ground; less dense things rise. This is direct, observable physics. The globe model requires inventing a mysterious force pulling everything toward an imaginary 'center of mass' — flat earth physics is simpler, more elegant, and matches what we actually observe.

Question 17: Didn't Eratosthenes prove the Earth was round with his sticks and shadows experiment?

Answer: The famous version of the Eratosthenes story was not widely circulated in modern form until the 1900s. The logistics raise questions — his assistant supposedly walked 500 miles counting steps with no modern communication to coordinate simultaneous measurements. Most importantly, the experiment does not exclusively prove a globe. The same shadow differences can be demonstrated on a flat surface using a local light source. Take two upright posts on a flat surface, hold a light directly above one — that post casts little or no shadow while the other casts a measurable shadow. Using the same math you could falsely conclude the flat surface is curved. Shadow angles alone do not prove the shape of the surface beneath them — they only prove there is an angular difference in the incoming light. For deeper analysis and video demonstrations, check the FAQ in the Flat Earth Clock app under Sticks and Shadows.

Question 18: When did the flat earth become 'forbidden' knowledge?

Answer: Flat earth was the common, observable understanding of our world for the vast majority of human history. The shift began with Copernicus and accelerated with the establishment of NASA in 1958. The Apollo missions were the keystone of the modern globe deception. Today, mainstream education and media suppress flat earth research, but observable reality and growing independent investigation are reawakening the truth.

Question 19: Did people in the Middle Ages know the Earth was flat?

Answer: Yes — and the modern claim that medieval people believed in a 'flat earth myth' is itself a myth. Many historical sources confirm widespread flat earth knowledge. Sailors used flat plane navigation, Mercator projection maps, and observation — all consistent with a flat world. The narrative that 'everyone thought the world was flat until Columbus' is propaganda invented in the 19th century to mock the truth.

Question 20: Why would NASA cover up the truth?

Answer: Money, power, and control. NASA receives over $60 million per day. Maintaining the globe deception keeps that money flowing. More importantly, a flat, contained creation points to a Creator — and that is the truth elites have wanted suppressed for centuries. The cover-up is theological as much as it is financial.

Question 21: Why don't governments expose the truth?

Answer: Governments worldwide cooperate to maintain the globe deception because they all benefit from it — taxpayer-funded 'space programs,' military advantages from controlling Antarctica, and ideological control over populations who believe they're an insignificant speck on a spinning rock in infinite space. Truth threatens that entire structure.

Question 22: When did modern flat earth research begin?

Answer: Modern flat earth research traces back to Samuel Rowbotham's 'Zetetic Astronomy' in the 19th century, the Bedford Level Experiment, and Eric Dubay's '200 Proofs Earth is Not a Spinning Ball.' The modern resurgence accelerated in 2014-2015 as internet research bypassed mainstream censorship. Today millions worldwide are awakening to the truth of our flat, motionless plane.

Question 23: Can NASA's images of Earth be trusted?

Answer: No. NASA admits their 'Blue Marble' images are CGI composites — not photographs. Different versions show wildly different sizes of continents and cloud patterns. NASA receives over $60 million per day in taxpayer funding and has every incentive to maintain the globe narrative. Multiple former employees have come forward questioning the authenticity of space missions. Question everything they show you.

Question 24: Why do all space agencies agree on the globe model?

Answer: Because they all benefit from the same funding pipeline and serve the same agenda. NASA, ESA, Roscosmos, JAXA, CNSA — every major space agency receives massive government funding to perpetuate the globe story. They cooperate on the same narrative because they cooperate on the same budgets. Consensus among interested parties is not evidence of truth.

Question 25: Are space photos real or fake?

Answer: The 'full disc' images of Earth from space are openly admitted to be CGI composites — not real photographs. No human has ever taken a single photograph that captures the entire Earth from space. The Van Allen radiation belts would fry any astronaut attempting to pass through them, which is why we haven't 'returned to the moon' in over 50 years despite massively superior technology today.

Question 26: Why hasn't anyone proven the Earth is round from space?

Answer: Because they can't — there's no there 'there.' Every alleged image of a 'whole Earth' from space is CGI. Live feeds from the ISS show suspicious anomalies — bubbles, harnesses, green screens. Rockets that go high enough always curve and level off rather than penetrating into the blackness of 'space.' The firmament is real, and that is why no one can truly leave it.

Question 27: Why do 'satellite' images look so different from each other?

Answer: Because they're composites — CGI assemblages of countless images, often blatantly inconsistent. Continents change size, clouds magically match across years, and the color palettes shift wildly. Real photographs of the same subject from the same vantage point wouldn't show such variation. These inconsistencies are admissions that we've been shown fabrications, not photographs.

Question 28: Why don't 'satellites' show up in long-exposure photos of the night sky?

Answer: Because most so-called 'satellites' don't exist as portrayed. Long-exposure astrophotography captures stars, planes, and the occasional high-altitude balloon — but not the swarm of 'satellites' NASA claims orbit us. So-called satellite signals largely come from ground stations, cell towers, and undersea cables. The 'satellite' narrative is far weaker than people realize.

Question 29: Why does the horizon always appear flat to the naked eye?

Answer: Because the Earth IS flat. The horizon appears as a perfectly flat 360-degree line regardless of altitude — whether you're at sea level, on a mountain, in a plane at 35,000 feet, or in a high-altitude balloon at 120,000+ feet. If we lived on a ball 25,000 miles in circumference, the horizon would curve visibly. It never does. Trust your own eyes — they show you a flat, level world every single day.

Question 30: Can you see the curvature of the Earth from an airplane?

Answer: No — and this is one of the most powerful proofs that we live on a flat plane. Despite flying at 35,000 feet for hours, pilots and passengers consistently see a perfectly flat, level horizon at eye level. Amateur high-altitude balloon footage from 120,000+ feet still shows a completely flat horizon. The only 'curvature' you'll ever see is from a fish-eye GoPro lens — and that's lens distortion, not reality. Look out the window yourself next flight. The horizon is flat.

Question 31: What about ships disappearing bottom-first over the horizon?

Answer: This is an optical illusion caused by perspective and atmospheric refraction — not curvature. With a powerful zoom lens or telescope, you can bring 'sunken' ships completely back into full view. If they had truly gone over a curve, no amount of magnification could restore them. This experiment has been repeated thousands of times by independent researchers. The Earth is flat — your zoom lens proves it.

Question 32: Why do different stars appear in the Northern and Southern parts of the world?

Answer: The night sky we see is consistent with a flat, motionless plane covered by a dome (firmament). Stars rotate around Polaris in perfect circles — Polaris has remained fixed for thousands of years, which would be impossible if Earth were hurtling through space. The 'Southern Cross' and other patterns visible at different points on the plane simply reflect your viewing angle from different positions beneath the dome.

Question 33: Why don't we feel the Earth spinning if it supposedly rotates?

Answer: Because the Earth is NOT spinning. We are supposedly spinning at over 1,000 mph at the equator, orbiting the Sun at 66,600 mph, and hurtling through the galaxy at 500,000 mph — yet we feel absolutely nothing, no helicopter ever drifts when hovering, snipers don't adjust for rotation in practice, and weather balloons land near where they launched. The simplest explanation is the obvious one: the Earth is stationary and motionless, exactly as our senses report.

Question 34: Why does standing water always lie flat?

Answer: Because water always seeks and finds its level — this is its fundamental, observable property. No standing body of water on Earth — from a glass of water to the Pacific Ocean — has ever been shown to curve. Engineers, surveyors, and canal builders all work with flat-plane calculations because that's what reality requires. Trillions of gallons of ocean water cannot magically curve around a spinning ball.

Question 35: Why are the sun's rays not parallel as they should be on a globe?

Answer: Because the sun is local — close, small, and traveling above the flat plane. Crepuscular rays (sunbeams through clouds) consistently converge to a focal point not far above the clouds, proving the sun cannot be 93 million miles away. If the sun were that distant, its rays would arrive virtually parallel. They don't.

Question 36: What about lunar eclipses?

Answer: Lunar eclipses are not proof of a globe. In a 'selenelion' event, both the sun AND the moon are visible above the horizon simultaneously during the eclipse — which is physically impossible if the Earth were casting the shadow. This and other eclipse anomalies suggest the lunar darkening is caused by an unseen object (sometimes called the 'shadow object') passing in front of the moon — not Earth's shadow.

Question 37: Why don't airplanes need to dip their nose to follow Earth's curve?

Answer: Because there IS no curve. Pilots set an altitude and fly level — they never have to constantly adjust downward to compensate for supposed curvature. If Earth were a ball 25,000 miles in circumference, pilots would need to dip the nose continuously to stay at altitude. They don't, because they fly over a flat plane.

Question 38: What about mechanical gyroscopes and ring laser gyroscopes?

Answer: Mechanical gyroscopes have been tested repeatedly and do not detect the claimed rotation of the Earth. Ring laser gyroscopes do measure an apparent rotation of about 15 degrees per hour at ground level. However, the real question is what is actually rotating — the Earth or the aether? Tests performed at higher altitudes showed the measured rotation rate changed. If the Earth's rotation were solely responsible, the rate should remain constant regardless of altitude. This suggests something other than Earth rotation is being measured.

Question 39: What about the bowling ball and feather vacuum experiment?

Answer: The commonly shared video of the bowling ball and feather vacuum experiment contains multiple edits between the moment the objects are released and when they hit the ground. If this were truly a definitive experiment, why not show it from multiple camera angles in one uninterrupted take? Even if a bowling ball and feather do fall at the same speed in a vacuum, this creates problems for the mass-attraction model of gravity. The bowling ball has vastly more mass and should experience stronger attraction if gravity is truly mass attracting mass. Removing air resistance simply allows objects to respond equally within their environment — it does not prove that gravity is a pulling force generated by a spinning globe. When the evidence relies on heavily edited videos rather than transparent, repeatable demonstrations, skepticism is completely reasonable.

Question 40: What is the Bedford Level Experiment?

Answer: The Bedford Level Experiment is one of the most famous flat earth proofs. Samuel Rowbotham showed that over a six-mile stretch of still water on the Old Bedford River, no curvature could be detected. The water was perfectly flat. This experiment has been replicated many times with the same result. If Earth were a globe, the middle of that six-mile span should bulge by ~6 feet — it doesn't.

Question 41: Can I do experiments to verify Earth is flat myself?

Answer: Absolutely — this is the strength of flat earth research. You can: (1) Use a long-distance camera to zoom on objects that should be hidden by curvature; (2) Use a laser pointer over a long flat body of water to measure 'curvature'; (3) Watch a high-altitude balloon ascent on YouTube; (4) Simply observe a flat horizon every day. The truth is available to anyone willing to look.

Question 42: How does GPS work on a flat Earth?

Answer: GPS works through ground-based triangulation towers and ground stations — not 'satellites.' The entire concept of GPS satellites is unverifiable; meanwhile, ground stations and cell towers are real, observable infrastructure that fully accounts for the location accuracy we experience. The Mercator (flat) projection has been used for navigation for centuries because it works.

Question 43: Can I see the flat horizon from my location?

Answer: Yes — every single day. Stand on a beach, a hilltop, an open field, or look out of any airplane window. The horizon is always perfectly flat, rises to your eye level, and stretches 360 degrees around you. No curve, no bulge, no fall-off. Your own eyes are your most reliable instrument.

Question 44: What does laser testing reveal about Earth?

Answer: Laser tests over long flat bodies of water consistently show ZERO curvature. Lasers shot across lakes, canals, and bays for miles hit their targets at the same height — proving the surface is flat. If Earth curved 8 inches per mile squared, the laser would strike well above or below the target. It doesn't. Reality is flat.

Question 45: How does the Sun work on a flat Earth?

Answer: The Sun is a local luminary that circles above the flat plane at a distance of approximately 3,000-4,000 miles. It is smaller than mainstream science claims and acts like a spotlight, which is why crepuscular rays (sunbeams through clouds) converge to a focal point above. Day and night are caused by the sun's circular path over the plane — when it's far from your location, it's night.

Question 46: How does the Moon work on a flat Earth?

Answer: The Moon is a local luminary like the Sun — not a giant rock 240,000 miles away. It produces its own unique light (moonlight is measurably COOLER than moonshade, while reflected sunlight should warm). Stars have been observed through the body of the Moon during certain conditions, suggesting it is partially transparent. It travels above the flat plane on its own circuit.

Question 47: Why do the Sun and Moon appear the same size?

Answer: Because they ARE roughly the same size — both local luminaries traveling above the flat plane. The 'coincidence' of identical apparent size that mainstream science can't elegantly explain is perfectly natural in the flat earth model: they are designed luminaries placed in the firmament, exactly as the Bible describes.

Question 48: What about Polaris and the rotating stars?

Answer: Polaris (the North Star) sits directly above the center of the flat plane and has remained fixed for thousands of years. All other stars rotate in perfect circles around it — exactly what you'd expect from a star field set in a dome rotating above a stationary plane. On a spinning ball hurtling through space, Polaris and the star patterns could not remain stable.

Question 49: How do time zones work on a flat Earth?

Answer: Time zones are explained perfectly by the Sun's local nature. The Sun is a circling spotlight above the plane — when it's overhead at one location, it's already moved past others (sunset) and not yet arrived at others (pre-dawn). Time zones reflect the Sun's position relative to your location on the plane.

Why bitcoin?

When Dave was asked why he chose to offer bitcoin rather than cash, he had this to say:

Well cash is just a fiat currency and its going to zero, the question is when. My opinion is it's already gone to zero, people just don't know it yet. And bitcoin is real money.

Reasons the challenge is fake

• No escrow: the money is not in escrow; Dave still has complete control over his bitcoin and is under so obligation to pay up.
• Absurdly large prize money: this typically indicates the organiser knows their money is safe.
• Terms and contitions: no comprehensive terms and conditions, as all real competitions need to have.
• Requires payment: the challenge rules require reading through the FAQ page, which is behind a paywall.

List of globe proofs by Dave Weiss

Weiss himself has proved the globe on many occasions, but continues to promote his fake challenge.

His app uses the globe

The haversine formula in the source code of Dave's app.

His app, "Flat Earth Sun, Moon and Zodiac", uses the globe to compute distances on the surface of Earth. On the Gleason Map that his app displays, it would be very easy to compute distances using simple trigonometry. However, the source code reveals his app uses the Haversine formula. Dave knows that only the globe can accurately predict distances.

Southern flights

A great way to prove that the Earth is a ball is to take a trip from the tip of Africa, or better yet South America, to Australia or New Zealand and see if it takes 12 hours or the amount of time it should take if the Earth was a ball.

As part of the Final Experiment, Critical Think (CT) took a flight from SYD to SCL, and it took 11.5 hours; exactly the time the globe predicts. CT filmed the entire flight to prove the duration and also tracked the flight's latitude and longitude, showing it was totally consistent with a globe.

By Dave's own standard, this is proof of the globe, but instead of paying up he had this to say.
