This is a game that was inspired by Ray Bradbury's "The Golden Kite, The Silver Wind", which is in a short-story collection called "The Golden Apples of the Sun". In the story, the walls of two cities were constantly being rebuilt to beat the other city.
If I made my city a stick, you could be fire. You have to "build" your walls into something that can destroy the previous person's city. It is not actually made out of the material. It is just shaped like it.
You cannot do something like a "diamond sword". You can only do a "sword"! You cannot specify what the object or thing is made out of!
I will start by STICK
Magma
Black hole.
Gravity
This has escalated quickly.
A white hole continually emits matter (in theory). A white hole would emit straight into a black hole, just making it larger. (I say in theory as iirc they have not been observed like black holes.)
And now I am very interested in what would happen if a white hole were to enter a black holes event horizon...
Interesting....Supposing that there is "infinite" gravity, maybe they would just cancel eachother out.
Not at all, a black hole accelerates everything towards it at the speed of light, literally nothing can cancel it out afaik. Even two orbitting black holes just cause a larger event horizon. We don't even know if a white hole has some sort of anti gravity, as they have no explanation, and are just speculation. We have no reason to think they exist.
