Kicking around on a piece of ground… how cats spend their days

21 June 2013

The movements of ten cats living in relatively close proximity to each other in Shamley Green, a village in the English county of Surrey, were the subject of a recent study. Each feline was outfitted with a GPS tracking collar, and their activities monitored over a twenty four hour period.

Some of the findings may prove surprising though. As any moggy owner knows, cats are territorial, but here they appeared, at times, to share turf with their neighbours, so long the felines in question had no direct contact with each other.

It’s also interesting to see how far some cats roamed, relatively speaking, from their home, with some appearing to visit what looked to be an isolated spot, some distance from their usual stomping ground, once a day. What would be the deal there?

The Alcubierre Drive, a means of faster than light speed travel?

6 June 2013

Could NASA be developing a means of moving through space at speeds greater than light? Apparently so. The trick though to travel at speeds faster than light is to generate a space, rather than a craft, that exceeds light speed, and then slot a vessel into that space.

It’d be as if you were going down a water slide, or something, where the water is moving you, and you’re just along for the ride.

Traveling faster than light has always been attributed to science fiction, but that all changed when Harold White and his team at NASA started to work on and tweak the Alcubierre Drive. Special relativity may hold true, but to travel faster or at the speed of light we might not need a craft that can travel at that speed. The solution might be to place a craft within a space that is moving faster than the speed of light! Therefore the craft itself does not have to travel at the speed of light from it\’s own type of propulsion system.

Intriguing, if nothing else.
