Here's another dot spark to glider that only requires the dot sparker to have a period of 24 or more, which is still unlikely but more likely than the one in the previous post. 34P14 shuttles are only an example and can be replaced with any period sparker that doesn't get destroyed.

I know I have 4 of the last 5 posts, but here's a p60 almost gun in a 24×32 bounding box (total 768); the only issue is that the gliders crash into the pentadecathlons. There has to be a way to do this. (You can merge it with the previous post if you're able to keep the newer timestamp on it.)

What exactly do you mean by that?

I am not reporting anything new; I am just noting that this is the smallest-known odd-period gun.

[MathAndCode]

I am just noting that this is the smallest-known odd-period gun.

After discoveries such as electricity, radio, and integrated circuits, how does only a new smallest odd-period gun imply that God is dead?

[Aleph]

After discoveries such as electricity, radio, and integrated circuits, how does only a new smallest odd-period gun imply that God is dead?

I agree. Suppose god does not exist. Then god is not dead, because they would need to exist to die.
Suppose god does exist. God is still not necessarily dead-the creator of the universe could easily add something to prevent us from killing them.

Religious discussions are off topic for this thread.

Good job, everyone! I wonder if a smaller pseudo-period 14 glider gun can be constructed with the new p42 one? I tried for a while but didn't find a p6 or p7 domino sparker for the GIG.

After reading about the p42/p63/p84 period-multiplying mechanisms I realised that the old blocker trick suffices to turn p84 into p168:
