Fact Check: the earth is flat

The Claim: "The Earth is Flat"

Introduction

The assertion that "the Earth is flat" is a long-standing belief that contradicts centuries of scientific evidence supporting the Earth's spherical shape. This claim has gained traction in recent years, particularly through social media and various online communities. Proponents of the flat Earth theory often present arguments that challenge established scientific understanding, leading to a resurgence of interest in this fringe belief.

What We Know

1. Historical Context: The idea of a flat Earth was prevalent in ancient civilizations, but empirical observations, such as the way ships disappear over the horizon and the round shadow of the Earth on the Moon during a lunar eclipse, led to the acceptance of a spherical Earth by the Greeks and later by the scientific community 27.

2. Scientific Consensus: The overwhelming consensus among scientists is that the Earth is an oblate spheroid. This conclusion is supported by various lines of evidence, including satellite imagery, gravitational measurements, and the physics of planetary motion 410.

3. Flat Earth Beliefs: Despite the scientific consensus, a segment of the population continues to advocate for flat Earth theories. Research indicates that these beliefs are often intertwined with broader conspiracy theories and skepticism towards mainstream science 369.

4. Arguments from Flat Earthers: Proponents of the flat Earth theory often cite perceived anomalies in scientific explanations, such as questioning the nature of gravity and the curvature of the Earth. They may also rely on anecdotal evidence and personal observations that they believe contradict established science 810.

Analysis

The claim that the Earth is flat is primarily supported by anecdotal evidence and interpretations of physical phenomena that lack rigorous scientific backing.

• Source Reliability:

  • NASA and Scientific Institutions: Sources such as NASA 2 and Scientific American 6 provide credible, scientifically-backed information that supports the spherical Earth model. These institutions are recognized for their rigorous scientific standards and peer-reviewed research.
  • Flat Earth Advocates: Articles that present flat Earth arguments, such as those found in IFLScience 8 and the Pursuit article 3, often highlight the psychological and social factors contributing to belief in flat Earth theories. However, these sources may not provide empirical evidence supporting the flat Earth claim itself.

• Methodology Concerns: Many flat Earth arguments rely on misinterpretations of scientific principles or selective evidence. For instance, claims about gravity and its effects on a flat Earth lack empirical support and contradict established physics 410. Furthermore, the methodology used by flat Earth proponents often does not adhere to scientific rigor, leading to conclusions that are not substantiated by reliable data.

• Potential Bias: Some sources discussing flat Earth beliefs may have inherent biases, either in favor of debunking these theories or in promoting them. For example, articles from scientific institutions aim to correct misconceptions and promote scientific literacy, while flat Earth advocates may present their views in a way that appeals to anti-establishment sentiments 369.

What Additional Information Would Be Helpful

To further evaluate the claim that the Earth is flat, additional information could include:

• Comprehensive surveys of flat Earth belief demographics and psychological profiles to understand why individuals subscribe to these theories.
• Peer-reviewed studies that analyze the cognitive biases and social influences that contribute to the persistence of flat Earth beliefs.
• More detailed examinations of the specific arguments made by flat Earthers, along with scientific rebuttals that address these claims directly.

Conclusion

Verdict: False

The claim that "the Earth is flat" is conclusively false, as it contradicts a vast body of scientific evidence demonstrating that the Earth is an oblate spheroid. Key evidence supporting this verdict includes historical observations, such as the round shadow of the Earth on the Moon during lunar eclipses and the way ships disappear over the horizon, as well as modern scientific consensus backed by satellite imagery and gravitational measurements.

It is important to note that while flat Earth beliefs persist among certain groups, these beliefs are often rooted in misunderstandings of scientific principles and a mistrust of established science. The arguments presented by flat Earth proponents frequently lack empirical support and rely on anecdotal evidence.

However, it is essential to acknowledge the limitations in the available evidence. The persistence of flat Earth beliefs may be influenced by psychological and social factors that warrant further investigation. Understanding these dynamics could provide deeper insights into why such claims continue to resonate with some individuals.

Readers are encouraged to critically evaluate information and consider the credibility of sources when encountering claims that contradict established scientific understanding.
