The Seven Wonders of the Ancient World | The Mausoleum at Halicarnassus.

Description

The Mausoleum at Halicarnassus or Tomb of Mausolus was a tomb built between 353 and 351 BC in Halicarnassus (present Bodrum, Turkey) for Mausolus, an Anatolian from Caria and a satrap in the Achaemenid Persian Empire, and his sister-wife Artemisia II. The structure was designed by the Greek architects Satyros of Paros and Pythius of Priene. Its elevated tomb structure is derived from the tombs of neighbouring Lycia, a territory Mausolus had invaded and annexed c. 360 BC, such as the Nereid Monument.The Mausoleum was approximately 45 m (148 ft) in height, and the four sides were adorned with sculptural reliefs, each created by one of four Greek sculptors: Leochares of Athens, Bryaxis of Halicarnassus, Scopas of Paros, and Timotheus of Epidaurus or Athens. The Mausoleum contained 400 freestanding sculptures. The mausoleum was considered to be such an aesthetic triumph that Antipater of Sidon identified it as one of his Seven Wonders of the Ancient World. It was destroyed by successive earthquakes from the 12th to the 15th century; it was the last surviving of the six destroyed wonders. The word mausoleum has now come to be used generically for an above-ground tomb.Source: Wikipedia.orghttps://en.wikipedia.org/wiki/Mausoleum_at_HalicarnassusThe New Period Chat Radio presents: Seven Wonders of the Ancient Worldhttps://www.youtube.com/@thenewperiodhttps://www.youtube.com/playlist?list=PL6upa16ru_Cz0QV19XB-KWBpDNZ8N4Ukehttps://www.youtube.com/@thenewperiodcrhttps://rumble.com/c/c-5025829https://www.bitchute.com/channel/JtdWZsd7QnbPhttps://rumble.com/c/c-5025829Patreon page: https://www.patreon.com/hectorvladimirSubstack page: https://hectorvladimir.substack.com/Hector Vladimir 2026©#mausoleum #mausoleumathalicarnassusMusic by Christodoulos HalarisThe Greeks OSTNarrated by Hector Vladimir in 2017

Currently, we struggle to come up with acceptable rationales to begin to plan for it. Not only that, but the task is of gargantuan difficulty. Interstellar travel is limited by several major factors, including physical and technical, and the human factor. The physical challenges include the vast distances among stars, and the time that separate suns are just incomprehensible. Other physical factors include the interstellar medium, which is hazardous with radiation and celestial objects. And, the lack of gravity is one bonus challenge that we can overcome, not after massive investments. The technical challenges are many. We lack the overall state of technology to undertake an interstellar mission. We have not the rocket power, the payload to LEO capacity, the energy and material resources, nor the infrastructure required to even begin an interstellar program. And, we lack the word industrial, scientific, and political cooperation to gather the needed resources for this largest of projects. Lastly, the human factor puts the final nail in the coffin of interstellar flight. Introducing many problematic situations with our needs as humans. The nagging problems of space radiation, low gravity, isolation, distance from earth, and hostile environments; all bring hurdles to any interstellar mission. In fact, the human factor is the largest hurdle to such mission. However, I do believe that someday we will fly across the stars, but not in the way that many envision. I believe it will happen in an unexpected but “sure-fire” manner. This short book describes the challenges and possibilities with interstellar human travel. Enjoy.
