Universe Sandbox is an interactive space simulator for Windows based PCs. Unlike most astronomy software that just shows you what the sky looks like or where the planets are, Universe Sandbox is a powerful gravity simulator. You can add another star to our solar system and watch it rip the planets from their orbits.
Posted on 21 Jan 2011 at 13:34 ISPs are threatening to cripple websites that don't pay them first. Barry Collins fears a disastrous end to net neutrality You flip open your laptop, click on the BBC iPlayer bookmark and press Play on the latest episode of QI. But instead of that tedious, plinky-plonky theme tune droning out of your laptop’s speakers, you’re left staring at the whirring, circular icon as the video buffers and buffers and buffers... That’s odd. The end of the net as we know it | Broadband | Features
The Measurement of Science Albert Einstein’s greatest scientific “blunder” (his word) came as a sequel to his greatest scientific achievement. That achievement was his theory of gravity, the general theory of relativity, which he introduced in 1915. Two years later, in 1917, Einstein ran into a problem while trying to apply general relativity to the Universe as a whole. At the time, Einstein believed that on large scales the Universe is static and unchanging. But he realized that general relativity predicts that such a Universe can’t exist: it would spontaneously collapse in on itself.
As the country remains highly polarized and chronically dissatisfied with the performance of the two major parties, the internet, and advent of social media in particular, could catalyze the historic campaign of an Independent presidential candidate as early as 2012. Joe Trippi, the internet guru behind Howard Dean’s remarkable 2004 presidential campaign and the mind behind Jerry Brown’s 800 number fundraising effort during his 1992 presidential run, echoed this sentiment at the South by Southwest Interactive festival’s recent gathering. Now trending: the internet could usher in an Independent revolution that topples the two-party establishment | CAIVN

Massive Earth-like planets that have both continents and oceans may be better at harboring extraterrestrial life than those that are water-only worlds. A new study gives hope for the possibility that many super-Earth planets orbiting distant stars have exposed continents rather than just water-covered surfaces. Continue reading "SuperEarths with Exposed Continents Boost Chances for Extraterrestrial Life" » In 1980 and 1981 NASA's Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet's uppermost clouds surrounding its north pole.
If the popular misreading of Mayan mythology is correct, we have fewer than two more years left on this Earth. That leaves precious little time for the tech industry to develop and perfect of all the cool technologies that sci-fi authors have dreamed up over the years. Still, while a December 2012 apocalypse may spell doom for the commercial viability of hovercars, it doesn't mean that the next couple of years in tech will be dull — quite the contrary. 2011 is already shaping up to be a banner year for tech and web innovation. Below is a list of over 40 websites, apps, companies, gadgets and technologies that the editors of Mashable think that you should keep an eye on over the coming year.
