ejecta

Since the area is not specified, they'd err on the conservative side, cleaning a maximal range for any of their possible ejecta.

If the lines end up converging towards a crater, then they are caused by ejecta from a meteorite impact.

As you mention, this would be through ejecta transfer - some primordial bacteria hitching a ride on interplanetary asteroid impact debris.

In hypothesizing possible causes, I wonder about the relative size of the ejecta of a type 2 super nova.

So for example, if you have a bunch of crater ejecta, what can you tell me about the mass of the incoming objects?

Perhaps you could use Ejecta when they ask for iOS support?

What JS chart tool play well with ejecta in iOS?

Because Ejecta supports only the canvas element.

If we don't sterilize our craft, how do we then verify either that life arose independently on a non-terrestrial surface or that ejecta carried it?

This means it's not really stressing a JS runtime and could probably perform great under an interpreter (as demonstrated by Ejecta getting a good framerate) It also doesn't appear to produce a taxing GPU profile even on a canvas implementation.

One of the coolest things I learned from the original blog post [1] on Ejecta was a trick that the library uses for drawing polygons on the GPU in OpenGL without triangulating them first [2].

Hard to say, the Northern lights would move to the other hemisphere, the entire sky might glow if the field were not present (solar ejecta hitting the atmosphere everywhere) It is possible that the Van Allen radiation belts would vanish and reform in a different configuration.

All I can remember from it is that they estimated the ejecta at "about the mass of the Sierra Nevada".

The plus side is: If you manage to make a basic UI like in a "game" with canvas only, you'll get near-native performance, since Ejecta implements an OpenGL-enhanced canvas element.

Not only that you then layer the javascript on top of that with a 3rd party javascript interpreter (Ejecta)....

Ejecta has been supporting WebGL for a while now.

You can get near-native performance with Ejecta, which is something like a WebGL enhanced Canvas-only version of a web browser to put the game on the App Store.
