Yeah. I'm not counting on this but it'd be stupid to overlook it.

Well, we have magic, we might be able to do it even if it's not possible in this universe without.

We'll have to test it. On a continent no one's watching.

Risky to just try it on Angband?

I mean, we either don't hit hard enough and tip the Enemy off or we do but don't know how close is safe to stand. It won't be as well aimed as actual rocket scientists can do.

I am not sure there's anywhere you could test without tipping him off.

Really? Valinor's not a candidate for other reasons, but empty islands?

None that we know of. And he might hear such an explosion, and Ulmo might be furious.

Empty continent, then, and we can just not test in the same place twice in case it does get his attention. I don't know how much there is to learn from a crater.

Could know he needs to protect Angband against that avenue of attack.

Hm. His magic's slow, right? We could try a couple tests, and the real one as soon as possible if they're accurate enough to be safe.

That is probably the way to go, yeah.

Good, then the rest's just a practical problem. I'll have to borrow Elenwë and check if gravity still works, and if so we'll need whatever metal you can get that's hardest to melt.

I will start inquiring.

In the meantime, back to spamming the Enemy or are you planning to give the practitioners the rest of the break they earned?

Back to spamming the Enemy. It seems likely it did something.

And if it does the same thing again, maybe we can throw things at him while he isn't at his strongest.

Yep.

So the people who know what the festival's really about get rotated out to resume chanting things at Melkor. Amber prioritizes talking math and gravity with Elenwë; the final product could be needed at any time.

Gravity: behaves at least in the sense that objects accelerate when you drop them. They don't have the precision instruments to test more than that.

Lead balls and wire? Would have been nice to have some numbers to run. They do have unfair advantages in the preventing air currents department. 

Well, do objects accelerate at the same speed and parallel directions regardless of where above the disc they're dropped from? If so then it doesn't make sense but at least aiming will be easy.

That is how it works at least unless you get close to the edge.

Which they are not.

If whatever the Valar did to make down be down instead of hubwards keeps applying regardless of altitude, they can just send projectiles up and ram them back down. The main limitation would be how much mass they can do it with, not whether they can time an orbit right.

There are no signs that the false gravity stops behaving the way it does higher up, until they get high enough to see the whole disk. At that point things they drop start skewing oddly and where they land is not predictable at all.

Valar. If they could have figured out the "get a bunch of stuff and leave it alone" strategy for making spheres, this would be a lot more effective. As it is they'll have an upper bound on height and probably speed.
