Hewkii's Mask

Just to warn you, this is sort of a storyline rant. Don't take it the wrong way -- I like the story, always have, but sometimes things just need to be said, you know. This time around, it's about Hewkii's mask power.

I'm reading through Prisoners of the Pit again, and Hewkii is using his mask of Gravity to make a 200-foot venom eel slam into the sea floor and a Takea shark float helplessly away to the surface. And I'm thinking this is just one of the most miserable plot defects I've encountered in Bionicle. When you're maneuvering underwater, what is the force that makes you sink or rise? It ain't gravity. It's bouyancy. Density determines "weight" underwater, and mass is almost a negligible factor. The hardcore theorizers will blame it on altered physics, but honestly, do the same tweaked physics that allow for a life-supporting ocean magically cause water pressure to cease to exist? Gravity is the most useless power to have in the ocean. Consider this: the same multi-ton ocean liner that sits like a permanent fixture on land stays afloat in water. That's what it's engineered to do. It's all about density. A compressed block of steel of the same exact mass of the ship would sink like a stone in the ocean, but the ship is constructed with specialized, hollow chambers that make it of greater volume without ever increasing its total mass, therefore decreasing its density. And that turns that hopelessly sinkable block of steel into a reliably bouyant sea vessel. See how relatively little it takes for density to overcome the "mighty" pull of gravity? How could Hewkii use the force of gravity against sea creatures endowed with natural floatation mechanisms?

Just thinkin. =]

BTW, I will be away from the net until a week from Sunday.

Also, if you would be so kind to read this post, tell me what you think.

Gravity keeps all the water and sand onto the planet's surface and prevents it from going out into space. ;)

Think about it, if you increase gravity thousands of times above normal, the most buoyant thing is going to crash downwards. ;)

Your first sentence -- that's absolutely correct. Don't forget that that's the same gravity that causes water pressure, the effect of water's "piling up on itself." The box on the bottom of a tower of boxes is the one that gets squeezed the most. So it is with the water at the bottom of the ocean. It gets squeezed, and the sqeezing gets gradually less intense as you go toward the surface. You know how you can squeeze a sliver out of your skin? The water squeezes objects in it to places of lower pressure, and since the pressure gradient gets less intense upward, that's what causes objects to float up to the point at which their weight and the squeezing force are in equilibrium -- and that point isn't always at the surface, it can be at some point below. Where that point is depends on density.

 

You make it sound as if bouyancy equals weight, but they aren't the same thing. At some point, gravity could win over on an extremely bouyant object, but it would have to be ridiculously powerful. Like putting out a house fire with a lawn sprinkler.

It affects the object. But there are more "ridiculous" mask powers. Shielding? Dimensional Gates? Illusion?

. . . reanimation. . .

Because that would be hugely inefficient and therefore a big evolutionary no-no. You just don't get aquatic creatures that have a natural tendency to sink.
