Supernova-X
Posted: June 3rd, 2012, 2:55 pm
Experimenting with backrakes many years ago, this pattern has been saved from an old computer. It grows in a chaotic fashion and does not stabilze because there are many interfering streams of gliders. It is called Supernova-X because it looks like a five pointed star that is exploding and always expanding. The repeating X pattern is formed by streams of gliders expanding in all four directions. The complexity increases in the center through millions of generations. It may eventually stabilize but at 280 million generations it is still growing chaotically, although it has a basic star shape. But even the star shape begins to deteriorate eventually.
The pattern is basically equivalent to just two backrakes and a debris pile, but I am posting the original file:
You will need to use hashing and take it out to 5 million generations or more to see what causes the chaos. New X patterns occur at 1 million, 2 million, and then more frequently after several more million generations. There are a few LWSSs and even a couple of MWSSs traveling North and South. Since they are faster than the gliders they show up past the perimeter of the star eventually. I have not seen an HWSS yet, it is remotely possible.
Again, this type of pattern can be made with just two backrakes and a still life or other "debris pile". In this case the "equivalent" backrakes are a P128 LWSS backrake and a P64 glider backrake.
If someone has a fast computer with lots of memory I would like to know if it is still going strong at 1 billion gens and beyond.

But even at 14,016,768 generations you see a lot of things. You can see a lot of pieces of 'dust' around the rapidly cracking 'star', which are gliders that had split up earlier from the main group.
