Video showing an unidentified flying object splashing down into the Pacific Ocean off the coast of San Diego two years ago appears to have been corroborated by military radar which shows as many as 14 UFOs swarming a Navy combat ship while traveling at speeds of more than 160mph. Earlier this month, investigative filmmaker Jeremy Corbell released footage showing what appeared to be a spherical object floating in the air above the ocean as it was observed by US Navy sailors aboard the USS Omaha in July 2019. Corbell on Thursday released another video of the same incident, only this...

To Rice materials scientist Rouzbeh Shahsavari and graduate student Sung Hoon Hwang, the spheres represent building blocks that can be made at low cost and promise to mitigate the energy-intensive techniques now used to make cement, the most common binder in concrete. The researchers formed the spheres in a solution around nanoscale seeds of a common detergent-like surfactant. The spheres can be prompted to self-assemble into solids that are stronger, harder, more elastic and more durable than ubiquitous Portland cement. "Cement doesn't have the nicest structure," said Shahsavari, an assistant professor of materials science and nanoengineering. "Cement particles are amorphous...

Linux can't be understood in terms of hierarchy. Neither can the Internet. That's because both are examples of heterarchy at work. Flatland, an 1880 novella by Edwin A. Abbott, is about a world with just two dimensions, inhabited by lines and polygons. Trouble starts when a sphere shows up. For business, the same kind of trouble started when Linux and the Internet showed up in the mid-1990s. No matter how useful Linux and the Internet prove to be, business still has trouble getting its head around a virtual world composed of end points that are all autonomous, self-empowered and at...

A team of astronomers is now looking for Dyson Spheres, massive star-scale solar power plants that extraterrestrial hunters hope alien civilizations employIn 1960, mathematician, physicist, and all-around genius Freeman Dyson predicted that every civilization in the Universe eventually runs out of energy on its home planet, provided it survives long enough to do so. Dyson argued that this event constitutes a major hurdle in a civilization's evolution, and that all those who leap over it do so in precisely the same way: they build a massive collector of starlight, a shell of solar panels to surround their home star. Astronomers...

At least 200 have been found, and extracted out of deep rock at the Wonderstone Silver Mine in South Africa, averaging 1-4 inches in dia. and composed of a nickel-steel alloy that doesn't occur naturally. Some have a thin shell about a quarter inch thick, when broken open are filled with a strange spongy material that disintegrates into dust upon contact with air. A complete mystery according to Roelf Marx curator of the South African Klerksdorp Museum, as the one he has on exibit rotates on its own, locked in a display case, free of outside vibrations. The manufactured metallic...
