Fluorescent hot pink post-algae-quasi-worm species that live on a moon under a bright uv star living symbiotically with black plants. Their broad leaves look like tar paper joints during the day, but at night, they unroll and do their photosynthetic thing from underneath by the light emitted by the quasi-worms.
Ooh, what a lovely idea! And it opens up a whole can of (quasi-)worms . . . er, questions. Like, how did algae evolve into such a helminthoid animal? And will diurnal herbivores eat the plants' leaves if they're all rolled up? Or is the rolling-up a defense mechanism to save the plants from defoliation by slash-and-burn herbivorous animals? Will eating the plants when they're rolled up like tar paper joints get the herbivores high?

An intentional naming, or a curious coincidence?
It's the latter. I came up with the planet name when I was 15, and had never heard of Harvey Keitel.
Ha! Course I had Gen. Wilhelm Keitel in mind!
I had to look him up. What a terrible man. [:(]

I've been reading about coreless planets, and I'm wondering if it is possible they could contain a strong magnetosphere?

By coreless, I mean a world that has no metallic core or magma, and is entirely rocky mantle.

Is there a way I can get around having a core in order to have a magnetosphere?

The idea for my world is about a society with no metal, and I thought "Hey, what about an entire planet without metal?"

There's metal in our bodies .... calcium, iron, etc .... though if youre willing to radically rework the evolution of life, you could perhaps have us getting our body's firm parts from something like chitin, which is non-metallic, or silica, which is what plants' thorns often come from.
I'll take the theses, and you can have the thoses.

Not a coreless planet, but a planet with no metals could. It could use a core of just hydrogen to create a magnetosphere, but otherwise the core of the planet must be metal to develop one

Could a planet with a hydrogen core still be earth like in that it could support carbon based life, have continents and oceans, etc?

How would humans fare?

"Could" is a difficult word.

We should reiterate that anything could happen in a fantasy world. It could literally be made out of cheese if you wanted it to be. Naturalism is not the only route here.

However, if you do want to be naturalistic, then you have some pretty massive problems here.


A planet with no core

The core is what creates the magnetosphere. No core, no magnetosphere. Also, no plate tectonics, which probably means no carbon cycle, so probably no breathable atmosphere and little climate stability.

A planet with no metals

People are made out of metals. If you have no metals, you have to complete throw out earth biology and start from scratch. [the obvious one is calcium for bones, but small quantities of iron, magnesium, selenium and so forth are essential for cellular processes.

A gas core

What happens if your world has gas at the centre? Well, we need to distinguish two very different scenarios: hollow earth; and gas planet.


---------------

A hollow earth

In this scenario, the mantle is made of rock, but the core is made out of gas. What happens? Well, it could get quite complicated.

The first thing to say is that it's almost certainly impossible. You know what happens when you have a lot of rock sitting on top of gas? It falls down. The entire weight of the mantle would be pushing down on its inner surface, and nothing but hot air would be holding it up. No vault could be perfect enough to not allow some of the rock to fall - and then ALL of the rock would fall.

Now, it could theoretically be possible. If you make the gas hot enough and dense enough, the pressure of the gas attempting to escape could equal the weight of the rock pushing down on it. It's hard to imagine this working in practice, though - surely, even if it were globally true, there would be small areas where it wasn't true and grains of rock would fall. As rocks fell, the gas would expand into the gaps, and eventually it would find a way to burst out and the planet would explode. After all, our hot liquid rock in our planet periodically bursts out the top - but fortunately, liquid is a lot less explody than a pressurised gas!

The real physical killer, though, is how such a situation would arise. It's one thing if a god sets it up like that (they could make the inner surface of the mantle out of solid, impervious unobtainium, for a start). But in nature, you could never all all the rock converging simultaneously to trap exactly the right amount of gas in the middle - instead, like grains in a sieve, the rock would inevitably fall to the bottom while the gas floated to the top.

One fun thing about a hollow earth, though: inside the mantle, there is effectively no gravity!

Oh, and about hydrogen forming a magnetosphere: yes, if it's metallic hydrogen. Specifically, it needs to be liquid metallic hydrogen. Metallic hydrogen only exists at insane pressures (it's debated whether we've ever managed to produce any). Even the pressure at the centre of our Earth is not great enough to produce metallic hydrogen!

-------------------

A gas planet

It is conceivable that life could exist in a gas planet. There can be a band in which liquid water is possible, and conceivably at reasonable temperatures and pressures - such a band does exist on Venus, for instance, which isn't a gas planet but does have a big atmosphere. So far as I'm aware such bands don't exist on our gas giants - high enough up to have normal pressure, and you're very, very cold; warm the place up and you get crushed. But it should theoretically be possible, I'd have thought?

Obviously, though, you wouldn't have any earthlike life. Clearly you couldn't have continents and oceans - as you can observe, rocks are heavier than air, so they would fall down (once you reached air that was dense and hot enough for continents to float on... well, then you'll have some survivability problems!).

So when I filled the star motif of this flag after using the pen tool it looked like this:

It's pretty good, but I'm thinking I could also make the octogon into a circle or fill in the white spaces.
What do you think of it?

It's best the way it is. Neither circlifying the octagon nor filling the little white spaces would improve it, I think.

lol, your avatar.

If anyone is irked. I won't spam the threads with this sort of thing, maybe find a discord server.

Not at all. This is precisely the kind of thing this thread, and indeed this forum, is for!

In fact, rather than the chat we engage in on the discord, it would actually be nice to see longer, ooey-gooey loret-porridgey posts detailing the meaning, history, and culture behind this flag!

My avatar was not the reason to make this suggestion. I do think your flag looks more interesting than mine the way it is.

As elemtilas said, this subforum is an appropriate place to talk about your flag. If you want to go further than just "quick questions", I'd suggest the Symbols of Concultures thread, where there is plenty of flag discussion. You can also make a thread specifically for your conculture.
