Who / (Who Not)	What / (What Not)	When / (When Not)	Where / (Where Not)	Why / (Why Not)	How / (How Not)	Emerging Categories
Who travels?	What is space?	Why now?	Moon, planets?	To colonize?	Spaceship	Probe, knowledge transport, material transport, colonize
Adult, children, old age?	Vacuum	Lack of resources	Under earth/rock of moon/planets	Humans move	(Not by spaceship)	Types of Force
Men or women?	What moves in a vacuum?	Too many people on one planet	Under ground biosphere/space station	To learn? Discover?	How else could one travel?	Ethics of machine growth
Big/little, tall/short?	What doesn't move in a vacuum?	To gain more resources	Too hot, too cold => underground	Machine learning/discovery	Hitch a ride on a comet	Matter manipulation
Intelligent or learning?	Space/time continuum	To make money	What is the temperature underground on a planet far from Sun? Close to sun?	Humans don't have to physically travel to learn or discover	Create a comet, create a man made orbital object, create a planet	Categorization of questions and possibilities is the goal.  In doing this new knowledge is created.
Machine only	Absence of matter	Global greenhouse gases	How to get underground?	Discover precedes travel?	Telescope/instruments on comet
AI machine	What is anti-force of a vacuum?	Environmental woes	Cave, dig tunnel, blast?	Do I know where to travel to before I discover it?  Trips are planned.  Destination is planned.	Nanoship
Should people travel?	What attracts an object in a vaccum?	(Not now)	(Sun)	Probes - To discover	Can't take people… Could move resources…Could be a probe
People travel to colonize, don't need to travel to learn/discover	Magnetism?	(Learn to live here)	Propelled by sun?	Nanoprobes	Nanotransport
Probe => discover/learn	What is force?	Why soon?	Outside solar system?	Nanoprobes on launched from comet	Solar sail nanoship
Can perfect biosphere from earth.	Something that can something else	Same as above	No heat	Raw materials/resources?	Knowledge transport?  Intersteller communication?
Ethics:  Learning machine/Discovery machine	Types of forces?	Can it wait?	Space station?	Can we use interplanetary resources on earth?	How to transport material?
Ethics:  Self-replicating probes	Attraction, propoulsion, repulsion, gravity, wind, orbital, pressure	What is a planning threshold?  E.g., 100 years?	Incremental travel? (Biosphere to Biosphere)	Would interplanetary resource use on earth create unsustainable waste?	Transport through ship
Private or governmental?	Every action has an equal and opposite reaction	What is goal?  Colonization?  What are incremental steps?	Traveling biosphere	Lack of food/water	Transport through light
Cost prohibitive	Grow force?	Affected by rise in tech?	Where life is sustainable?	Lack of energy	Transport through line
Who pays for travel?	What is travel?	Pull trigger to colonize too quickly?	food, atmosphere, water	Lack of oxygen
Metaphor: taking a trip	Move from one place to another	When we can [insert what]	Must probe	Lack of time	(Do we want to transport material?)
	What power?		Where resources are available	Lack of motivation	Light
	Natural power, reactive power, explosive power		Wherever there is matter	Too complex	How to probe?
			Must probe	Extreme heat, cold	Laser light probes
	What speed?		What is matter?	Gaseous surface of some planets	Light transport
	What sustenance?		What are resources?	Harsh environments	Biosphere ship
	Ship only or people?		Things that sustain or provide material to construct or provide fuel	Poisons
	Opposite:  Stay		Where energy is available	Lack of money	Wormhole
	Leverage other planetary resources	I did not develop these questions, but you can go as deep as you want.		(Raw material valuable)	Biosphere ship
	Machine:  Oxygen from water			Transport raw material?	Intermediate space stations
	Machine:  Matter manipulation			Lack of atmosphere	Anti-gravity
	Machine:  Power from matter			Create atmosphere	Solar sails
	Machine:  Power from matter vs. space	This process creates a problem scenario that can be built upon long-term			Rsk of material contamination
	Food, water, shelter				Underground space stations
	Types of Probes?
