For a pattern like this, with n cells in the top middle area:
`x = 13, y = 4, rule = KnuthArrowsD\$A.8A.2A2\$A.8A.2A!`

The speed is approximately C/2^^^^^...^^3 with n-2 arrows.
Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night

Ahh, so for 1 cell, then n cells, then m cells, it's asymptotic to c/2^^^^^...^^m+1 with n-2 arrows.

What will be the next step in how slow the spaceships will be?
I'm deleting the post and reuploading it the second time, and still nobody answers?

Well, first off, try doing some research yourself if you are really that desperate. Second, I am not sure what the next step is. Some of the other Turing machines on the page I referenced are able to calculate much larger values, so if you want to port them into Golly, you might be able to create slower ships.

### Re: Real Life Speeds

Saka, earlier in this thread, wrote:Idea:
1. A dot creates a c/2 dot moving left and spawns a binary counter that counts to the left.
2. Once the counter hits a certain point (noted by a dot), it starts counting down (If possible) and is moved 1 cell to the right.
3. After countdown has finished, the counter is turned into a c/1 dot moving left and a dot marking the position, but 1 cell to the right.
4. Once the c/1 dot catches the c/2 dot, it turns into a c/1 dot.
5. The c/1 dot moves to the right until it hits the binary counter marker (See #3).
6. Repeat.

This would be REALLY slowm

I made a rule based on that idea, with a few small changes.

The c/2 photon turning around is a bit wonky because it uses the vonNeumann neighborhood.
Example ship (c/178o):
`x = 7, y = 1, rule = ChaseShipA5.G!`

It isn't that slow, but the minimum population is the same for every speed (besides c/2 and c/1, technically).
Fastest possible ship with the same format:
c/19o
`x = 3, y = 1, rule = ChaseShipA.G!`

(Speeds c/2o and c/1o are also possible, but they aren't that fun.)

EDIT: Can anyone figure out the formula for the period?
EDIT2:
Dani found it:
6*l+2^(l-3)+2^l-8
where l is the width of the ship

I like that rule. This ship goes at speed c/301990048, which is the closest to 1 m/s (0.992722972 m/s) I could get:
`x = 28, y = 1, rule = ChaseShipA26.G!`

### Re: Real Life Speeds

This is interesting, as you can see by the graph, the periods of the ships start to skyrocket at around width 45 (according to the function in the original rule post)

### Re: Real Life Speeds

How large must the fourth ship be?
`x = 21, y = 3, rule = ChaseShipA.G\$A8.G\$A19.G!`

I feel we have a fast-growing function, though it won’t grow VERY fast.

How large must the fourth ship in that line be so that it won’t be destroyed and stopped by the previous one?

In this version, instead of creating a photon "reactivator", it uses another binary counter, and once the binary counter reaches the ship, it creates a photon that erases the counter and bounces back and reactivates the ship. This keeps the constant population at 2 and makes it slower as well.
Fastest: c/76o
`x = 3, y = 1, rule = ChaseShipBinA.G!`

The width 4 ship has speed c/1589o and the width 5 ship is a c/393309o. I've calculated that the period for the width 6 ship is around 6 442 451 107, give or take at most 2.
I have yet to find the formula for the speed.

I'm in the middle of making a rule for a new ship. I've created half of the process, and I'm taking a break for my mind.

### Re: Real Life Speeds

For Saka's newest rule, for a gap of n, the period is equal to:
`3 * 2^(3 * 2^(n-1) + 2n - 1) + 15 * 2^(n - 1) + 10n +3`

A gap of 100 has a period with more digits than could be stored on Earth.

To make a spaceship, you make a state 1, and then a gap (choose how long), then a state 2.

I don’t know the function for the speeds. At first, it looks like it doesn’t get slower than c/26 but then it matches up, and continues to slow down.
