Podría haber una antigua civilización enterrada bajo el Sáhara

Video Description

Hace apenas 6.000 años, el Sáhara, el desierto cálido más grande del mundo, era un territorio verde, lleno de agua y de vida. Recientemente se han encontrado los restos de diversas culturas de cuya existencia no teníamos noticia hasta ahora. Y es posible que, bajo sus arenas, se escondan los restos de una o varias civilizaciones de cuya existencia aún no hayan encontrado pruebas los arqueólogos. En este vídeo documental en español os contamos los enigmas que envuelven el Sáhara, desde la prehistoria hasta el Antiguo Egipto. #misterio #historia #documental Los científicos han hallado evidencias, en sedimentos marinos y lacustres, de que, durante el transcurso de los últimos ocho millones de años, en el Norte de África se han sucedido más de 230 procesos de desertificación y reverdecimiento. Sucede de manera cíclica, cada 21.000 años aproximadamente. ¿Cómo es posible? A finales de 2023, un equipo de investigadores encabezado por el climatólogo de la Universidad de Helsinki Edward Armstrong, publicó en la revista científica 'Nature' una posible explicación. Las leves oscilaciones en la precesión orbital de nuestro planeta –es decir, el cambio lento y gradual en la orientación del eje de rotación de la Tierra, que hace que este apunte a diferentes estrellas a lo largo de grandes periodos de tiempo– provocan, cada 21.000 años, que el hemisferio norte se oriente hacia el sol más de lo habitual durante los meses de verano. Eso provoca veranos más calurosos en el hemisferio norte, con un aire más cálido y que, por tanto, puede retener más humedad. Los investigadores, tras desarrollar un modelo climático que simulaba con precisión la circulación atmosférica sobre el Sáhara y el impacto de la vegetación en las precipitaciones, llegaron a la conclusión de que ese fenómeno que se produce cada 21.000 años intensifica la fuerza del sistema monzónico de África Occidental y desplaza la franja pluvial africana hacia el norte. Ya no llueve solo en las zonas subsaharianas, sino en el propio Sáhara. Como resultado, la sabana y los pastizales boscosos se expanden hacia el norte, cubriendo lo que hasta entonces era desierto, desde los trópicos hasta el Mediterráneo, proporcionando así un vasto hábitat para plantas y animales. Al cabo de entre cinco y seis mil años, la precesión orbital provoca que los veranos vuelvan a ser más fríos y el Sáhara se convierte de nuevo en un desierto. No se sabe con exactitud cuándo se inició el último proceso de desertificación en el Sáhara, pero debió de ser un evento bastante rápido, incluso brusco, hablando en tiempos geológicos, porque hay evidencias de que poco antes del 4.000 a. C. aún había amplias zonas verdes en el Sáhara y, en cambio, hacia el año 3000 a. C. ya era tan seco como hoy en día. El caso es que, si el Sáhara, periódicamente, se convertía en un entorno muy favorable para la vida..., ¿no es posible que, durante su último periodo verde, albergara alguna gran civilización cuyos restos hayan quedado sepultados por completo bajo las arenas actuales? Puede sonar como una idea descabellada, en este mundo de avanzada tecnología en el que la geografía parece incapaz de esconder nada a nuestros satélites, pero recordad que, como hemos comentado, el Sáhara ocupa casi nueve millones y medio de kilómetros cuadrados. Y, según diversas estimaciones, menos del 1% de toda esa superficie ha sido explorada con técnicas arqueológicas modernas. Tradicionalmente, la mayoría de excavaciones en el norte de África han sido organizadas y financiadas por gobiernos e instituciones extranjeras. Y estas, como es normal, se han concentrado allí donde se sabía, con un alto nivel de probabilidad, que se podrían obtener resultados. ¿Y dónde era eso? Habéis acertado...: en Egipto.
