XIETIAN
it seems he can manipulate gravity only up/down (to 15x). it would be cool if the skill evolve so he can freely adjust the direction of the gravitational force/field. (aka can make attacks miss to any direction or make space chaotic by continuously and randomly adjusting the intensity/direction of gravity)
Gravity is essentially an effect of "bending" space-time. And what does bending mean? Well, if you make a 4 dimentional graph representing how space changes with time, you will see the lines curve, compressing space towards the center of gravity. In case you're wondeing if this compression would mean stuff inside grows smaller, that isnt the case: other fundamental forces can lock particles in their position. How does that work? Idk, ask an expert in relativity, or something. Well, back to the fact that space compresses, if you got the image, you should notice that the space around the center is "moving" towards it: that is gravity. There is no force that keeps us on the ground, it is space that moves "downwards" dragging with it its contents. If space moves down, yet we "stay in place" we experince an upward acceleration, thus the feeling of weight. How can space move/compress relative to the objects within it? Idk, thats just the most correct representation I could getafter exploring the topic for a long time. There are many things that could make this representation feasible, specially if you realize that moving time and space variables in relativity's equations can lead to versatile results: I have seen some yt arguing that the time dialation caused by gravity leads to the force as we know it. Which actually makes sense, if you do your own reasoning with the aid of some equations, you can find that dialating time can cause gravity, just like the mainstream equations say that gravity dialates time. Why am I explaining all of this? Well, I guess it would be interesting to point out that gravity hability, if it were thought of with real world physics (mercy on this one, if my thoughts are wrong, I am not a physicist), is derived frpm control over space, time or both. Perhaps he won't be able to control those concepts individually, to preserve the "fairness" of the mc's op level, but I have to point out that gravity control is space-time control in the real world: I mean, the creation of portals, or stopping time, might not work in the real world, since such extreme actions should cause extreme repercussions: such as supernova explosions, or just an error in the simulation, that might force us awake from this virtual reality.
If you’re trying to be scientifically accurate with this gravity manipulation skill it’s gonna be real tricky and very op. Since it can effect fire that means it can effect plasma and gas. Meaning it also effects the air. The air at the peak of Mt Everest is 1/3 as dense as at sea level and people can suffocate due to lack of oxygen. Flipping gravity that can effect the air to 1/15 will effectively suffocate anyone that needs any kind of air in a matter of minutes if not seconds. Ok, science lesson is over. 🥳
