Planetary Collision

When an asteroid or a moon collide with another celestial body will this collision cause the planet to break into pieces? Will this pieces then fly around in the system ?

At least not currently and I have not seen any plans to do this.

that's acually a super good question and the right time to be asking this kinda stuff.

Apart from being a gigantic middle finger to physics, that would destroy an entire planet, instead of what you're trying to destroy.

Planet smashing works, but it's not finished. It still has a long way to go.

how so? our moon was formed this way.

Yeah, it seems fairly common.

However is it a good gameplay addition considering that we don't play on the same system for centurys?

I remember a guy here was talking about how electromagnetics can rip mountains off of planets and bring two celestial bodies close enough to collide. I asked him for a source but I never got any response.

Also, this isn't really a giant middle finger to physics as some would believe. A planet is a very thin shell of loosely coagulated rock surrounding a superheated lava lamp, with a really tough, really hot, semisolid core. And that's just for our planet; most planets are piles of dust in a remotely ball-shape.

Eh, think of it this way. I'd consider a normal weight for a full grown human male 180 pounds. Imagine something about 1/10th your weight, 18 pounds, being hurled at you at several hundred miles an hour. HURTS, DON'T IT?

They've talked about the effects of planet smashing. Craters will be made, so their goals are to have battles rage across pockmarked planets and moons and after getting hit several times, lava will start bubbling up and stuff. And from Uber's verbiage I've gotten the impression that after enough smashes planets will eventually be completely destroyed.

No definitive word on that as far as I'm aware.

You can't just 'shatter' a planet. To shatter the earth, for instance, you would need 1.129 x 10^32 J (Earth's gravitational binding energy). Considering an asteroid going at 72 km/s (the fastest speed anything orbiting the sun can hit the earth with) and that all the kinetic energy of that asteroid would be converted to 'shattering energy', without any energy loss (which is impossible), said asteroid would have to have roughly twice the mass of Triton. So if we're talking in realistic orders of kinetic energy to shattering energy (I like that term), we're talking other planets.

And the moon breaking off is something completely different to (as well as happening during completely different circumstances than) shattering the Earth.

But I still stand to my point that it would be kinda game breaking when you just want to hit the planet instead and completely blow it up instead of a specific point on the planet and only blow up your enemy.

ok that is in no way citable as an argument.

he's doing up-in-the-air-talk the kind scott manley does.

He's using references from the incidences known in his field of study, notice the "just about", that translates to : "including but not limited to". He's saying that's the case as most asteroids hitting our planet come from the outside of our solar system, don't swing around our sun first and don't generally have superior speed. here we're talking about moving an orbital body with engines powerful enough to do so (which by the way has no common ground with science) and swinging around the sun a couple times to pick up speed.

so what we're doing here, in terms that you can understand is "a gigantic middle finger to speed limits" (of course not anything crazy as we can still see it moving, so probably something close to 72km/h anyways, it doesn't matter, the impact with an orbital body twice as big would instantaneously bring both orbital bodies to fusion temperature on the surface and probably send a lot of magma if not chunks into space.)

I wonder what wierd effects bringing relativity into the engine would have on the game, with the whole "your perception of time depends on how fast you're going/how close to a large mass (planet) you are" thing going on. wait, maybe we already have that, it's called clientside lag, when you try to smash an asteroid...

Relativity doesn't really come into play on normal celestial scales, at least not in the time scales of battles, which last hours at the most. Maybe if you were on... You know, the surface of a star, you might notice a difference.

But then you'd be on the surface of a star.

Yeah I know it doesn't come into play at these scales, but I meant, what if we implemented if for the game, in such a way that it does come into play. Not a serious suggestion, mind you.

mod material.

Pretty sure there was some research published recently that suggested this wasn't the case actually.

Not to say it's not a possible, credible theory, this paper just suggested it wasn't the case with our moon.

EDIT: can't find any evidence of the research. Maybe I dreamed it.

My mistake, I thought we were talking relatively small things to planets, not planets to relatively small things.

Also, those Earth statistic are only viable when you're actually talking about Earth and the Sun. I was just using them for reference, you can't use them on just any solar system.

But I might also be putting too much thought in a game I don't even (intend on) own(ing).

Hey,

cool that a nice discussion started around that topic. But beside this speed stuff which I can't judge if it is right or wrong wouldn't it be incredible cool if a planet would blow up into pieces when it would be hit from another celestial body? That is a game, haven't seen commanders walking around the earth with spraying nano stuff around do you?

I can imagine that it could be complicate to calculate / render a planet breaking into pieces, what would about simply having a probability of the planet collapsing when it is hit? When this would happen a timer would start for a couple of minutes which would give you time to escape. When the time is over the planet would simply explode. To make this one easier the whole screen simply gets blended for a couple of seconds when it explodes and then the new asteroids are on their way? For galactic war this could be even cooler think about sending asteroids or planets even to other solar systems ... Or simply having flying them to other other solar systems by mistake?

ya uh, you're really gonna have to find that research.

In any case people do a looot of researches. You can publish a research if you want saying that baby boys are born on
Mars and baby girls on Venus then, transported to their parents by the kindly, peaceful nazi aliens that dwell on the dark side of the moon if you want to.

It'll be criticized as crap and laughable by a bunch of people, but you can still publish it. Then a bunch of other people will be able to cite it as scientific research.

The asteroid-crash moon theory is only a theory (...we have no proof) but it's the one recognized by NASA and illustrious scientists alike as the best and most probable theory there is.

And i'll just take the opportunity to revive THIS thread.

Yeah, I realise that, I'm talking about something published in a serious peer reviewed journal. Perhaps I read it in New Scientist? But I don't keep old issues and I can't seem to find it now.
I don't pretend to be an astro-physicist, this is gonna be an article from a magazine, but it wouldn't have been trash.
