Interstellar Travel And The Physics Of Interstellar Space Journeys
Interstellar travel and the physics of interstellar space journeys is considered in the sense of achieving it in a human life time.
A human life time is 122 years at overall maximum.
For interplanetary travel 10-25 miles per second is fine.
For interstellar travel 1,000 times that must be achieved or 10,000-25,000 miles per second.
For intergalactic travel in a human life time a system must go about 22,000 times light speed to reach the Andromeda galaxy.
The first thing is that the interstellar medium is mainly a vacuum.
It's not empty but it's the closest that could be to a 100% vacuum.
Because of this it becomes improbable that a very small projectile the size of a sewing needle would hit or be hit passing through the interstellar medium.
The second thing is that stars are very far apart on the scale of light years.
This translates into trillions of miles apart.
To journey from our solar system to any star system 4.
3 to 15 light years going 25,000 miles per second would take 35-125 years.
These are short time periods for star travel.
The amount of drag on a projectile in interstellar space is at the point of being zero.
The third thing is that all of the means that humans have produced since 1950 can't go fast enough to reach the next closest star system in a human life time.
Rockets and probes can only go about 10-20 miles per second.
This is fast of course but only for interplanetary travel.
It would take a little over 73,000 years at such a speed to reach the Centauri star system which is our next closest star neighbor.
Interstellar travel isn't difficult because all that's needed is a mechanically workable method to do it.
Such a method exists and is called 'The Johnson Rail'.
With the above written 3 matters of the vacuum of space, the distances to and between stars and the two dozen or so ideas produced to cross such distances we come to the simple physics of it.
The physics is to achieve 10%-15% of light speed (18,600 to 27,930 miles per second respectively) which are non-relativistic speeds to cross the distances in a short time.
The vacuum of space has no resistance so a device sent through it and can arrive at its' destination for stars 4.
3-15 light years distances within 35-125 years.
The physics is simple: send milligrams and not kilograms.
Use 1,000-20,000 watts of power and not megawatts or gigawatts or more.
This shows that there are only a few problems for interstellar travel and they're very easy to solve.
Accelerate a very small quantity of mass to 25,000 miles per second.
This sounds impossible but isn't! Why? Because the smaller the mass the less amounts of energy needed.
The less amounts of energy required the easier for humans to manage this in space.
The simpler the idea or concept the easier to find a workable mechanical method because the simpler the solutions to all of its' problems.
