Slightly off topic, and a little old, but I found while looking for more examples of Vegan Trekkers.
The reason your logic points to there always being 13 full moons in a year is because you are constantly changing the start of the year date to coincide with a full moon, as we are agreed that there are actually slightly more than 12 full moons in a year then your method will always result in 13 full moons making an appearance. However if you keep your starting point at a particular date, say January 1st, and the finishing date 365 days later, December 31st, then most years have 12 full moons, but roughly every third year you get 13 full moons. A full moon occurs every 29.5 days, bloody close to a month, hence the name m(o)onth.Lots of interesting stories, I’ll admit. Almost all in a context that is not real. It’s not the stories I object to, it’s the context. The stories, characters and action is the main draw of the movies – but to enjoy all these, one must accept the context of the movie. Much like in other types of movies. Say – a western. Horseback riding, oil lamps, saloons and six bullet guns belong – cars, airplanes, electricity and machine guns don’t belong. One cannot immerse themselves in a western when there are elements that make it obviously not a western.
In the same way, science fiction as a context relies on one’s ability to shelve reality in favor of a context that isn’t real.
The reason I asked you to consider the in water/in air scenario is to get you to think about the context of “gravity”. Do you think it works differently in water? This is the force that is supposed to be holding trillions of gallons of water to a spinning planet.
The correct answer to why objects rise or fall is relative densities, not gravity. A submarine in the water, what affects it’s depth? Gravity? No. Relative density. To dive, it releases air, changing it’s density in the water. To rise, it uses air compressors to add air to the sub, and change it’s density relative to the water so that it will rise.
Space is supposed to be a vacuum. In the water, you are surrounded by a dense material you can move around in. On the ground, you can move along the ground, but jumping up always means coming back down, not floating around. This is because you are more dense than the medium (air) that surrounds you. But water or air provide us something to “push off of” to move. Space, what do you push off of? It’s a vacuum.
But let’s say there was some magical quality about space that allows one to travel in it. So in other words, not a true vacuum. How does one defy the gravitation force that keeps planets spinning around the sun? Science fiction movies take this power for granted. It’s easy to jet around in space and defy this massive force that keeps planets both spinning and rotating around the sun. Even the so called rules of the universe are contradicted by most science fiction movies. One must put up with a huge amount of cognitive dissonance to accept the “reality” of them.
There are 13 moons in a year. Check this year, for example. Full moon was on the 21st January, 2019. If one counts to December, there are only 12 full moons. However, 21st of January to December 31 is not one year. In January 2020, there is a full moon on the 11th. Making 13 full moons between 21st Jan 2019 and 21st Jan 2020. Year after year after year, 13. If I’m wrong, point to a year where there was less than 13 full moons.

With regards to propulsion in space, rocket engines work obeying Newtons third law, every action has an equal and opposite reaction. The expulsion of the propellant acts against the motor that ejects it, causing a motion in the opposite direction equal in force to that released.
Relative density can apply alongside gravity, they don't have to be mutually exclusive.
The theory of gravity can be used to explain certain things, most commonly the moons gravitational effect on the Earths oceans, causing tides. That has nothing to do with relative density.
No, this is incorrect. If a full moon is not present in January, until say, the 20th, and there are only 12 from the 20th of January to December 31 - then it is incorrect to say there were only 12 moons in that year - because not a full year was counted. Therefore, it is necessary to go to the same date (the 20th in this case) of the following year to see how many moons there were in 365 days.
In a vacuum, there is nothing to "push off of".
Gravity is a magical force that keeps trillions of tons of water stuck to spinning earth, but is so weak it allows a helium balloon to defy it. If the moon was responsible for tides, why only for oceans? Shouldn't it also affect smaller bodies of water like pools and lakes?
It does, just to an extent that is barely noticeable.
It doesn't matter which date you use as a start date, providing that you continue to use the same start date for each consecutive 365 days, If you do so you will find that roughly 2 out of 3 consecutive sets of 365 days will have 12 full moons, the other one will have 13 full moons. That is a fact, and undeniable.
The force is an equal and opposite reaction to the force released by the rocket, it doesn't have to 'push off' anything

Do it and show me where I am in error. Please be specific and name the year, including a full 365 days from start of count to finish.
