The holograms you find on credit cards and banknotes are etched on two-dimensional plastic films. When light bounces off them, it recreates the appearance of a 3D image. In the 1990s physicists Leonard Susskind and Nobel prizewinner Gerard ‘t Hooft suggested that the same principle might apply to the universe as a whole. Our everyday experience might itself be a holographic projection of physical processes that take place on a distant, 2D surface.
NASA chief Charles Bolden announced the winners of the space agency’s commercial crew development competition to encourage progress in privately built spacecraft during a morning briefing at the National Press Club in Washington, D.C.
Not sure what to think about this article. What it’s actually saying is that the US is teaming up with Mexico to train people and test technologies for future manned exploration of Mars in the Mexican desert. So it’s not really as unusual sounding as the headline makes it out to be. The strange thing though is that the article in incredibly poorly written. I don’t know if that’s because it was babelfish translated into english or what, but it’s hard to follow the whole thing.
Gyre is meant to be a research station and an off shore resort, replete with gardens, shops and restaurants. Its shape is what is touted to make it a sturdy structure that can withstand ocean winds. Four arms extend from the center spire (1.25 kilometers in diameter). They keep the structure afloat and create a harbor large enough to accommodate huge ships.
A little while ago somebody made a prediction about self-contained buildings that operate on the same kind of principle as a cruise ship. This is kind of a similar thought. Unfortunately, because it has solar panels and wind turbines and water turbines they’re touting it as a sustainable tower in the sea. But can anything like a giant building floating in the sea be sustainable? Not even close, but it sure looks cool, and it’d be fun to visit.
