The Oort Cloud fascinates me.
It’s about 1 light-year away from The Sun, give or take, and is thought to surround us in a sphere basically…it’s lots of objects, balls of ice or rock or metal, whatever…it’s hypothesised that that’s where most of the things that hit our planet come from…
But the major thing that fascinates me is that if we ever gain the ability to travel at, or near, the speed of light, the Oort Cloud will basically save us from having to mine (and thus destroy) our planets just to get materials.
The balls of ice can be used for water, or even hydrogen. The water itself could be used to start terraforming a planet (throw lots of balls of ice at a planet, and shazam, it has water on its surface), the hydrogen for fuel. The rocks and metals? Materials, for building new space craft, or even starting work on the Dyson Sphere…
But, alas, if we were to use our current space travel methods (ie, a space shuttle), it’d take us just over 38,000 years to reach it…
