Uma visão algo fantasiosa dos Airbus de 2030...

Of all the aviation tech emerging from the Farnborough International Airshow, Airbus’ futurist visions are among the coolest.

The aviation firm unveiled its 2030 Concept Plane earlier this week, which includes dreams of a self-cleaning cabin; extra-long, slim wings; a U-shaped tail; and an intelligent fuselage designed to improve efficiency.

Airbus acknowledges the plane is somewhat a flight of fancy, but it’s worth imagining how aviation would look if advancements in existing technologies “continue apace,” as the company puts it.

Um novo tipo de Telescópio, qua vai ver o Universo com 500 vezes mais detalhe, e ainda por cima vai ser MAIS BARATO!


New Redshift-Scanning Technique Could Create Map of the Universe with 500 Times More Detail

It took mankind centuries to map the Earth, and even with all of the indexed knowledge in the world behind it Google can't always figure out exactly where the nearest Pinkberry is. So one might imagine how even with the amazing leaps in technology over past decades, mapping the universe is no small undertaking. But a new technique could allow cosmic cartographers to map 500 times as much of the universal landscape as they have thus far at a fraction of the cost.

We don't know a whole lot about dark matter, outside of the fact that gravity suggests that it's there. But we do know that galaxies exist in a sort of dark matter web that runs throughout the universe. Using luminous galaxies as waypoints, astronomers have been able to map this cosmic web to some extent, but galaxies more than 5 billion light-years away are too dim to survey. Since we know that the leftovers of the Big Bang have left us with a far-off waypoint that we've determined to be about 45 billion miles away, we can be sure that we haven't mapped the vast majority of the observable universe because we simply can't see it.
