Parth G's video: Physicist Reacts to asdfmovie - It s BOFFIN Time - Analyzing the asdfverse with Science

Could we really use physics to study what happens in the asdfmovie universe? And more importantly, why would we want to? Hey everyone, I'm back with a new video! This time, I wanted to make it a fun one, so I decided to analyze an asdfmovie sketch (from asdfmovie 3) with Classical Physics. If you're not use to the term "Classical Physics", it simply refers to the physics you're most likely to learn at school. It is primarily based on things like Newton's Laws of Motion. Classical physics has nothing to do with Mozart or Beethoven, don't worry. Now in this particular little sketch, our friend decides to "screw gravity" and float off into space. I wanted to see how this particular asdf universe compares with the universe that we live in, and how this character could decide to work against gravity and simply fly away. So my starting point was to apply the laws of gravitation that apply in our universe (which happen to be Newton's Laws of Gravitation, to a good approximation), and then make any tweaks as necessary. As it turns out, based on all the information we have in the sketch, it's perfectly reasonable to assume that the two characters in the sketch are on a planet like Earth before one of them decides to float away. Newton's Law of Gravitation states that the gravitational force exerted between two objects is equal to the universal gravitational constant, G, multiplied by the product of the masses of the two objects, divided by the square of the distance between their centres of mass. Now the universal gravitational constant, G, is a very important quantity. it basically encodes just how strong gravity is in our universe. If the value of G was bigger, then gravity between any two objects would be stronger, and if G was smaller then gravity would be weaker. My hypothesis is that before our friend floats away, Newton's Law of Gravitation applies to this adsf universe with the value of G being (maybe) similar to that seen in our universe. However, at some point our friend decides to hire Wizzo the Wizard to change the value of the gravitational constant to zero. This means that gravity no longer exists in the asdf universe. Surprisingly, even if gravity were to instantaneously disappear, our friends would not immediately float away from the surface of the Earth as stated by Newton's First Law - this is discussed in the video. So for one of them to fly away, they will have had to exert a force on the Earth (i.e. by kicking off) so the Earth would exert an equal and opposite force on them (Newton's Third Law). There are other ways to achieve the effect of our friend floating off into space. One way would be for Wizzo to simply change the mass of our friend to be zero. This way, there would no longer be a gravitational force between this friend and the Earth. However, everything else in the universe would still be the same and this is not catastrophic enough for a TomSka universe. Also, the happy look on the face of the other friend at the end of the sketch suggests that they're (1) amazed by the first friend floating away, and maybe (2) happy that they may be able to do the same - this would only be possible if the value of G was suddenly changed to zero.
