I sadly don't understand these units and your point is drained in it. The point I want to make is that the "force" of vacuum is limited by the difference of pressures.

You say it changes "drasticly" with area or suction but that is untrue. It changes linearly with area (not drastically) and pressure difference has a maximum. The maximum is defined by the pressure of the vacuum(=0) and the pressure of the ambient air (1 arm). Both are constant so the maximum is constant and actually not that big.

The difference between ambient pressure and inner pressure is always smaller than ambient pressure. Delta p is therefore limited. The force comes from Delta p times contact area which is constant.

I sadly don't know your units of mass but as I said a perfect vacuum over an area such as the Bowl is as strong as a muscle. The Ravioli will in no world produce a strong vacuum so muscle will win in most cases.

It's delta p and not fraction p. The difference between ambient pressure and inner pressure (at least zero) is always smaller than ambient pressure. Delta p is therefore limited.

The pressure acts over the area of contact. For a perfect vacuum it would lead to ~1kN of force. This is the same order of magnitude our muscles produce. If you take into account that the vacuum results from cooling over such a small temperature interval the force can't be too high.

The power of suction is physically limited. That means it either isn't suction or op is crazy weak. My guess is that the plastic melted (probably not from boiling Temp) or op is strongly exaggerating.

Chemically it's the smell of beet red. Most people describe it vastly differently because the retro nasal smell makes it feel like something else. Pretty interesting if you ask me.

I should be able to see the sun during the whole night. If it radiates in a cone the sun will rise in the middle of the sky. This model is - even for flat earthers - unimaginative.

I'm a physicist. If you are an engineer that sounds like a "you" problem.

It looks like a strategy game but actually isn't. The strategy part just isn't developed enough. It's a story and RPG style game with a strong focus on economy management. The game discourages strategy by telling you how strong an army is (as a number) and giving you no tactical option. Meaning higher numbers will always win.

The (new) DLCs are mostly very bad and short so the game as a whole is in a strange state where you can play a good game with missing features without DLC or you play a bad game with lots of features that is very expensive with all the DLC.

I kinda hope that the game dies soon because the frequent game breaking updates and optional (and disadvantages) DLC makes modding annoying even though there are extremely fun mods, even better than the DLC.

I always wondered what would happen if you cite an original source of something we consider common sense now. What would nature say if you use conservation of momentum and cite Isaac Newton and the Principia Mathematica.

What if you quote something in latin. For most of science history this was completely normal.
