[Desde la Ciencia] La Tierra es plana

by Óscar Cárdenas Hernández 40

Por: Óscar Cárdenas Hernández

23/agosto/2017 Autlán, Jalisco. (LF) O al menos así lo creen muchas personas. Algunas religiones y culturas en la historia de la humanidad han considerado a nuestro planeta como un disco plano y que es el centro del universo, y por lo tanto es posible encontrar diferentes modelos de una Tierra plana.

Sin embargo, en esta ocasión hablaremos de los postulados de un grupo internacional llamado “Flat Earth Society” o Sociedad de la Tierra Plana en español, que tiene entre sus miembros a personajes famosos de la música (como el rapero B.o.B.) y del deporte (como el basquetbolista Kyrie Irving de los Cavaliers de Cleveland).

La historia de esta sociedad data de principios de 1800, cuando fue fundada por Samuel Rowbotham en Inglaterra. Sus postulados sobre una Tierra plana estaban basados en la interpretación literal de pasajes bíblicos, sobre los cuales creó un sistema llamado “Astronomía Zetética” que establece que la Tierra es un disco plano cuyo centro es el Polo Norte, rodeado por una barrera de hielo en el borde “sur” del disco, como lo muestra la siguiente figura.

En este modelo de Tierra plana, el Sol, la Luna, los planetas y las estrellas se encuentran a unos pocos miles de kilómetros de la superficie terrestre. Por ejemplo, la Luna y el Sol estarían a unos 4,800 kilómetros de la superficie del planeta, y lo que Rowbotham llamaba “cosmos” estaría a unos 5,000 kilómetros.

Después de la muerte de Rowbotham en 1884, sus seguidores fundaron la Sociedad Universal Zetética (Universal Zetetic Society) y diseminaron sus ideas en Estados Unidos, donde el movimiento permaneció latente durante un tiempo hasta que fue re-fundada por el inglés Samuel Shenton en 1956. Después de su muerte en 1971, la sociedad fue presidida por Charles Johnson hasta su muerte en el 2001. Actualmente la Sociedad de la Tierra Plana es presidida por Daniel Shenton y mantienen un sitio en internet (https://theflatearthsociety.org/home/) donde se pueden consultar los argumentos que esgrimen sus miembros para defender la idea de una Tierra plana.

¿Y cuáles son algunos de sus argumentos? Aquí algunos de ellos.

  1. El horizonte siempre se ve plano, la Tierra no tiene ninguna curvatura. Aunque Aristóteles demostró la circunferencia del planeta en el año 330 AC y Eratóstenes calculó su circunferencia exacta en el año 240 AC.
  2. Las imágenes tomadas por satélites son falsas y forman parte de una conspiración mundial para evitar que la gente sepa que la Tierra es plana.
  3. La Antártida es una barrera de hielo impenetrable… Cuidada por personal de la Administración Nacional de Aeronáutica y el Espacio (NASA por sus siglas en inglés).
  4. La gravedad no existe, el planeta siempre está “subiendo” en un movimiento llamado “Aceleración Universal”, originado por una capa de “energía obscura” …
  5. El Sol está a sólo 4,800 kilómetros del planeta y tiene un tamaño de sólo 51 kilómetros de diámetro.
  6. Tanto el Sol como la Luna se mueven en círculo alrededor del disco del planeta, como se observa en la siguiente figura.

Aunque estos argumentos no tienen ninguna base científica, hay mucha gente que los cree. Se estima que alrededor de 10,000 personas forman parte de la Sociedad de la Tierra Plana e inclusive tienen presencia en redes sociales como Facebook y Twitter. Aún en pleno siglo XXI, todavía existe esta discusión…

¡Nos leemos en la próxima!
