Physics of Exotic Propulsion Promo

This 8 week course (Mondays, 17 June - 5 August 2024) will ask a simple question: If ET visitations are possible, then how would aliens get here? This course will briefly cover the history of human air and space travel first, with the historical claims that each were impossible. Then, after explaining Newtonian-physics-based propulsion, it will move on to describing the origins of Einstein’s Theory of Special Relativity (1905), explaining why the speed of light must be a constant and why that causes time to dilate (Twin Paradox) and length to contract, helping interstellar travelers along.
Students will also learn how we know relativity to be correct. The formulas for relativistic mass and energy will be explained from a qualitative perspective for the non-mathematically-oriented students. Problematic side effects like mass increase and starlight Doppler blue-shifting will be covered, with suggested solutions of new fuel sources and propellants like dark matter or energy, and new types of shielding against radiation, for relativistic spaceflight (still sub-light). At the course midpoint, case studies of UAP exhibiting high speeds / accelerations will be reviewed.
The course will then transition into General Relativity for handling gravity and acceleration, with a focus upon how this broader theory may allow for faster-than-light navigation of the cosmos, through the warping of the space-time fabric (gravitational waves and inflation will be discussed as examples) and Einstein-Rosen bridges, or wormholes. Lastly, the course ends with a discussion of non-relativistic solutions to observed UAP behavior using the classical mechanics of Newton and Galileo, emphasizing how Einstein is the icing on the cake.

If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (about 7.3 years would pass on Earth) and this includes turning the ship around halfway to decelerate. It would achieve about 95% light speed in 1 year. A 10 ton ship would require a mere 10 tons of continuous thrust. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way.
All that is needed to make this a reality is a fission rocket that can put out thrust for long periods and does not consume hydrogen. A true fission rocket should consume uranium or plutonium only. They are both jittery atoms that are on the verge of fissioning all by themselves, there should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion.
In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy the same should be true if you infuse them with energy. This might be as simple as having negatively charged uranium or plutonium atoms coming into contact with positively charged uranium or plutonium atoms.
With the constant acceleration method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 ship years.
