Space Colonisation

 Wormhole teleportation can be achieved by a circular gate having connecting projector on the inner rim to make a step through gate to a chosen other teleporter. A connecting projector can be achieved by funelling energy in a light ray of entangled photons. The photons can be entangled with photons at another gate.

 An idea for launching a spaceship is to put a track on a mountain or a scaffolf to launch it by a mach train into space. This negates the need for rocket fuel.

 To terraform a planet, dumpming healthy soil and seeds with water in it can bring about a biosphere.
