Could weight compounders destroy planets?

[Brackcha he/him]

Unless I'm mistaken it's weight that causes planets to have gravitational pulls so could weight compounders who had stored enough weight gain their own gravitational pull and mess up planets? Like could a person in mistborn era 3 take a rocket ship into space then make their own planetary sling and hurl their own planet out of the cosmere? Or better yet into other planets?

Technically, I believe it is mass that creates gravitational pull.

I think they would die long before they managed to tap that much weight. Also, unless they were compounding to an insane degree, I do not think a single person could store that much weight. I am not, however, 100% sure my interpretation of how this scenario would play out is correct.

 

edit: this thread might be better in the "Cosmere Q&A" section as it is not a theory but a... question.

How the weight tapping works isn't 100% scientifically sound, as Sanderson admits in AoL annotations. It's not quite gravitational and it's not quite mass related. Here's the quote

One thing I like a lot about Wax’s abilities is the power he has to manipulate his weight. There’s some realism to what he does—for example, increasing his weight doesn’t make him fall more quickly, but it allows him to do some powerful things while falling. Destroying the chandeliers is an example.

At the same time, I acknowledge that the weight manipulation aspect of Feruchemy is one of its more baffling powers, scientifically. Is he changing his mass? If so, he should become more dense, which I don’t actually make the case when it plays out in fights. (Otherwise, increasing his weight enough would make him impervious to bullets.) So, if it’s not mass manipulation, is it gravity manipulation, like Szeth and Kaladin do? Well, again, not really—as when his weight increases, his strength and ability to uphold that weight increase as well. Beyond that, Wax can’t make himself so light that he has no weight at all.

So . . . well, at this point, the ability to explain it scientifically breaks down. I do like what it does, but I have to set its boundaries and stick to them—and accept that some of what’s going on is irrational. (And don’t get me started on what should really be happening scientifically when Wayne speeds up time.)

I'm not a science/astronomy guy really, so not sure how that affects the answer to this question, but thought it pertinent to have this out there.
