VOLUME III: INTERSTELLAR Table of Contents

With traditional propulsion, 
flight to nearby stars take long centuries.
FORTUNATELY, g-force reduces flight time to a few years.

Unfortunately, fuel can severely limit duration/distance for interstellar g-force voyages; though, fuel is not a problem for interplanetary flights.  G-force vessels can easily carry sufficient fuel to accelerate at constant g-force throughout a trip to Mars, which would take a few days and only a few percent of the ship's mass for fuel.  However, interstellar vessels would easily consume well over 100% of its weight in fuel during the multi-year voyage.

Thus, interstellar g-force ships will conduct their voyages via 

three phases:

1. PHASE I. Accelerate at g-force for about a year to a significant percentage of light speed.
2. PHASE II. Cruise for a few years at this speed to save fuel (simulate gravity via longitudinal spin).
3. PHASE III. Decelerate at g-force back to near zero velocity for orbital operations at the destination stellar system.

Volume III: INTERSTELLAR

1.	INTERSTELLAR SCENARIOS Thought Experiment (TE) has grouped some common scenarios as:  1) Theoretical 2) Feasible 3) Practical.  Subsequent chapters focus on the practical.
2.	PUSH TOWARD INTERSTELLAR. Interplanetary performance envelope will need considerable "pushing" for interstellar flights. Particle exhaust speeds must be at least 86.6% light speed (.866 c).
3.	ACCELERATE FOR A YEAR: Compare spaceship's g-force speeds with c, light speed. See associated 1G TABLE: Accelerate for 1 Year.
4.	DETERMINE DUE DISTANCE.  Use exponential to determine g-force interstellar speeds; from integral calculus, use integral to determine distance duly traveled.
5.	TO NEIGHBOR STARS: Between an initial, year long, g-force acceleration and the voyage's final year of g-force deceleration, interstellar flights need a multi-year cruise phase to conserve fuel.
6.	PRACTICALITY: LIMITED RANGE G-force acceleration requires mass/energy conversion. Since spaceship has limited mass; it has limited range. Inevitable inefficiencies limit range even further.
7.	DYNAMIC EFFICIENCY FACTOR: Make the feasible range more practical with a dynamic efficiency factor which inversely correlates with vessel performance (particle velocity as it exits vessel's exhaust).
8.	FUSION WILL WARM US.  Fusion reactors will probably provide the power (though not the propulsion) for humans to live well and prosper during multi-year journeys to the stars.
9.	INTERSTELLAR SUPER G.  Unmanned AI vessels might use greater than g-force propulsion to resupply manned, interstellar vessels between the stars.  See associated 7G TABLE: Accelerate for 100 Days.
10.	SNOWBALL FROM OORT  From Oort's many comets, construct ice encased vessels to travel at interstellar super G throughout our stellar neighborhood.  See associated 7G TABLE: Decelerate for 48¼ days.
11.	ANNUAL SNOWBALLS  Interstellar travelers might need multiple resupplies throughout their voyage.  Thus, TE proposes more ways to throw more snowballs. See associated 1G TABLE: Decelerate for 1 Year.
12.	ENHANCED TIME DILATION. With annual snowballs, g-force vessels could conceivably accelerate to 86.6%c; then, passengers would age ½ as fast as Earth observers. (NOTE: Without "snowballs," practical cruise speed is 64.4%c; thus, STANDARD TIME DILATION TO AC:.)
13.	INTERSTELLAR COMMUNICATIONS Maintaining huge data flows over extreme distances will likely involve well planned placement of AI controlled, interstellar beacons.  IMPORTANT, these necessary, autonomous devices must actively avoid collisions, especially with the very vessels they support.
14.	INTERSTELLAR LIGHTHOUSES Like Earth's coastal lighthouses, neighboring stars can help us avoid enroute hazards. Singularities (aka "Black Holes") are especially insidious.
15.	HUBS: Sol's closest stellar neighbors can help humanity travel to even further stars. Vessels can stop there to replenish resources before traveling on. To better understand "hub" concept, also consider following.  OCTANTS: TE groups neighboring stellar systems (perhaps 51 within 15 LYs) into 8 octants. BEARINGS can help vessels precisely track distance along the course line.
