Factory in space, dark matter stars.....

Prototype in-space factory built

A company called Magna Parva has produced a prototype of an in-space factory that should be able to produce gigantic structures in space  without the need to launch them off the Earth. This could open the door to building things in space too big or too fragile to be launched on a rocket.

The 'dark stars' ( Which they aren't really since they wouldn't give off energy, but hey, it's a cool name and why be pedantic?) would be naturally forming Bose-Einstein condensates, where all the atoms inside acted as one. Here's the original paper, although it's pay per view.

Fraser Cain takes a look at wormholes:

Fraser Cain is editor of Universe Today, and pretty much one of the biggest space buffs around. Here he's taking a look at wormholes: In science fiction, wormholes are a method often used to travel great distances across space. First proposed by Einstein (amongst others) there's always ben a question mark in the theories about whether they could be built in real life, and exactly what they'd really do....
