Why, it's actually an eater. Just not a glider eater (and not known to be a spaceship eater as far as I can tell, until/unless someone discovers or engineers a spaceship that can be eaten by these two tubs), but nevertheless an eater:

Most likely there's a compatible glider synthesis for the unstable object eaten by the two tubs as shown, where the first interaction with the two tubs happens as shown and not at any earlier time.

EDIT: this suggests a question: which small objects can serve as spaceship eaters (when one is allowed to choose the spaceship)?

For example, is there a spaceship that can be eaten by a single ship? In principle one could find a salvo that has zero total effect when it hits a ship. However, most people wouldn't describe an arbitrary salvo as a spaceship.

In this case, this counts as a Glider Eater which recovers in 3 ticks.
And the conjecture "No glider eater can be constructed with a recovery time of three ticks or less" is false.

mmm, I would think eaters should only eat spaceships, otherwise they are just catalysts, but well, all eaters are catalysts already, just that some eaters manages to suppress blocks or blinkers too, so that makes this a bit ambiguous, but anyways, that's just a matter of personal preference here.

It also shows up in this conduit, but that's for a different reaction:

In this case, this counts as a Glider Eater which recovers in 3 ticks. [...]

The reason why (I think) that doesn't really count as a glider eater, was already suggested by WhiteHawk.

More precisely: the "glider" cannot be naturally rewound arbitrarily far back in time from that location. It cannot get there as a glider; it would necessarily interact with the tubs earlier. Therefore that pair of tubs is not a glider eater, as far as I see.

There might be a different spaceship that can be eaten by the same pair of tubs (xs8_25204a4), though.

Crossposting some (complete or partial) glider eaters, which look like they fit in this thread, but for some reason were labelled as "glider receivers". As far as I can tell, neither of these reactions as shown can work as a useful receiver, and I don't see an obvious way to make any of them work as a receiver.

The first RLE contains a glider eater. Second RLE contains an inaccessible "block and blinker" factory and a hard-to-access beehive factory (both factories are activated by a glider). The reply shows a variation which is a blinker factory activated by a glider.

Question: what are largest (measured by the minimum population) known spaceships edible by a single eater 1 (without any other catalysts or any sparkers)?

^^ The most likely outcome is that the answer will become "arbitrarily large", when someone discovers an extensible spaceship containing either a wick segment or a wave segment, such that when the "head" is eaten by a single eater 1, the remaining "tail" burns cleanly as a fuse without leaving any leftover junk.

Here is a finite eater that can eat arbitrarily large spaceships. Perhaps it is possible to find variants of the front that can be eaten by a single eater 1.

Yay! We made a wing eater! Can you add it to the wiki?

Is there a list on spaceship eaters?

Is there a list on spaceship eaters?

I think the most recent stamp collection posted on this thread was from several years ago now -- July 14, 2021. There was also an earlier collection of c/4 diagonal spaceship eaters by Gustone -- November 9, 2019. No wing eater in there, though, it seems.

As new things are found and need to be added to stamp collections in "collection threads" like this one, the usual way of keeping the thread organized and up to date is for someone to volunteer to keep a latest-and-greatest stamp collection pattern in the first post of the thread.

However, this thread happens to have been started way back in 2009 by Ajax, who hasn't visited the forums for over a decade.

Would anyone be interested in being the volunteer maintainer for the Spaceship Eaters stamp collection? I can arrange to give such a volunteer editing control over the first post.

Yay! We made a wing eater! Can you add it to the wiki?

There are unlimited numbers of spaceships, and many different ways to build eaters for any one of them. We don't have any kind of centralized record-keeping system, or any widely accepted metric for deciding if one spaceship eater is worth documenting. For example, is a smaller bounding box "better" than a quick recovery time, or the other way around? It depends on the situation.

But mostly spaceship eaters are something of a curiosity, anyway. If you think about it, they mostly come in handy only if for some mysterious reason there's a predictable source of spaceships somewhere -- and for some equally mysterious reason we want to get rid of them.

Spaceship eaters that allow for some kind of optional output signal are called stable signal converters, and are tracked on that thread. The most entertaining ones are for spaceships where a synthesis exists, and someone has made an X-to-spaceship converter for it, so that it becomes possible to close a loop. Ultimately maybe that's not always terribly useful, either, but at least it's not an immediate dead end!

Long story short -- I'm thinking spaceship eaters in general might not be quite newsworthy enough for each new example to need to get added to the LifeWiki.

My suggestion would be to update the Eater article with a link to an updated stamp collection of spaceship eaters in the first post of this thread, once that is brought up to date.

I might be able to help to update it, seeing as the frequency of new eaters here is currently about 1 per month.

Sounds good! There's probably a bit of one-time work to do, to look through the thread between 2021 and now, and copy/paste into the stamp collection any spaceship eaters that aren't already represented. And optionally maybe improve the labeling a little bit, so it's easier to find things starting from the initial far-out zoom level.

You should now be able to edit the first post. Let me know, probably by PM, if you have any trouble doing that, or if you want to pass on the Spaceship Eater Collection Maintainer's Hat to somebody else.

For example, is a smaller bounding box "better" than a quick recovery time, or the other way around? It depends on the situation.

Why not just list the smallest by bounding box AND by recovery time? This would make it easier to decide which ones to list. Nevertheless, the wing eater is the only one, so that should be listed.

I am making a spaceship eater collection, and the format will be like this. The yellow squares mean there are no variants for e.g. population/bounding box. The S and E numbers are to find the spaceship or the eater in the collection. The reason there's both is because there might be eaters that can eat multiple spaceships. Are there any suggestions?

Code: Select all

x = 265, y = 94, rule = LifeHistory
