The NASA Vehicle Assembly Building at the Kennedy Space Center in Florida is the world’s fourth-biggest building by volume. Built in 1966 to assemble the rockets for the Apollo and Saturn space missions – and later, the Space Shuttle – it’s the largest single-story building on Earth, ...
The growth of continental crust through melt extraction from the mantle is a critical component of the chemical evolution of the Earth and the development of plate tectonics. However, the mechanisms involved remain debated. Here, we conduct petrological and geochemical analyses on a large (up to ...
From a mechanical perspective, the changes in hydrological conditions in and around a landslide area are key factors in the pore water pressure buildup in the soil structure. This can cause a critical reduction in the soil’s shear strength provided by matric suction. The water infiltration ...
Scientistss have discovered the largest andoldest-known structure that was built by the ancientMayan people. Large and shaped like a(n)1.(长方形), the structure was builtbetween 2,800 and 3,000 years ago in what is nowthe Mexican state of Tabasco. Unlike the largeMayan pyramids built ...
The generally simple deposit structure is more suggestive of short-duration (hours to days) and high intensity (~ 10 11 kg s 1) eruptions, perhaps with hiatuses in some cases. These extreme discharge rates would be facilitated by multiple point, fissure and/or ring fracture venting of magma....
Unfortunately researchers stop working on it, Lead researcher has been changed, The Minister of local research has also been changed, and they are not concerned with this giant structure. I hope there are researchers from foreign parties that would complete the discovery. Sadahurip Pyramid. Reply ...
It rests on an artificially levelled mountaintop, and consists of three outer lines of gargantuan walls, 1,500 ft long and 54 ft wide, surrounding a paved area containing a circular stone structure believed to be a solar calendar. One block on the outer walls has faces cut to fit ...

Two of the largest protected areas on earth are U.S. National Monuments in the Pacific Ocean. Numerous claims have been made about the impacts of these protected areas on the fishing industry, but there has been no ex post empirical evaluation of their effects. We use administrative data docu...
