Cellular Automata Methods in Mathematical Physics
I came across http://publications.csail.mit.edu/lcs/p ... TR-615.pdf, which has a large number of CAs that model physical systems. Most of the ones I've seen look well within Golly's capabilities, so is there any interest in converting them?

Chained Gosper guns
I would be surprised if this hasn't already been discovered, but the queen bee shuttles in a Gosper gun can be chained so that they have an arbitrary number of barrels. The RLE should make it clearer... x = 288, y = 134, rule = B3/S23 277bo$277bobo$260b2o18b2o$262bo17b2o4b2o$249b2o12bo16b2o4b2o$249b...

ALPACA
ALPACA is a metalanguage for specifying near-arbitrary CAs, invented by Chris Pressey; It has some rather nice features, such as classes of states and fairly complex expressions specifying transitions. Currently, the only implementation is written in Perl and gives a rather crude, non-interactive te...

Re: Glider circuits: components and contraptions
Apropos of nothing, there is a binary adder in WireWorld that can handle arbitrarily large integers at http://www.quinapalus.com/wires8.html. This should be translatable into Life, though stabilising it might be tricky.

Re: Stable technology
But the Universal Turing Machine was implemented with p30, so it's certainly practical for computation.

Stable technology
Other than easy construction and asynchrony, what advantages does it offer over p30 and p46 technology? p30 90° reflectors can fit in a 9x23 bounding box and can receive another glider in 30 generations; the stable 90° reflector in Gemini has an 81x70 bounding box and takes 488 generations to recove...

Re: Speed of light is not constant!
Because Manhattan is not appropriate for Life: the distance between a cell and a cell diagonally adjacent to it should be 1, not 2.

Re: Spaceship speed limits
Well, the data transmission rate of the LST is so horrible that it only really makes sense if you want to transmit halfway across the universe. Each sequence of 10 pulses carries one bit and it has an insane cooldown time, so a line of c/2 spaceships would have a much better bitrate, at the expense ...

Re: Spaceship speed limits
However, most technology runs at either p30 or p46 or is stable, so you wouldn't be able to process the data fast enough.

Re: Spaceship speed limits
Allow me to clarify this to you. Information cannot travel more than 1cell/generation in Life. It is incredibly obvious; it derives from the axioms of Life. This is not a "philosophical" matter; it is hard mathematical reality. The Stargate does not send information at 15c/14; this is an illusion th...

Re: IRC channel
Yes, it was empty at the moment because all the people there are already on #esoteric, but there are quite a few people on right now.
EDIT: Wait, now I realise. It's ##gameoflife, with two hashes, not #gameoflife.

This seems the best place to say this: after a lot of Life-related discussions on Freenode's #esoteric channel and discovering that there seems to be no IRC channel for Life, we set up the ##gameoflife channel for irc.freenode.net. Please join!

Well, the title sort of says it all. What is the state of the art in communications at lightspeed? The most recent resource I can find is from 2008.
