How do you anons think the universe was created?
Do you think it was made by some higher power? Maybe a scientific phenomenon, or perhaps it was just always there.
All thoughts and beliefs are welcome, religion, scientific research or just personal beliefs, they're all just as valid to the question. After the universe was created, how did all the atoms and matter get there? What caused all of this matter to just appear? Excited to hear your thoughts.

Ever since I discovered it, I was fascinated by Conway's Game of Life. For those of you, who are not familiar with it: it is a cellular automaton with two dimensions on a rectangular grid with each cell having either the state "dead" or "alive". From any given state, the next state is computet by a very simple set of rules:

-if a cell has less than two neighbors it dies
-if a cell has two or three neighbors it lives on
-if a dead cell has three neighbors it becomes alive
-if a cell has more than three neighbors it dies

The attached image shows what patterns emerge. You can see still live, oscilators and gliders fliing around.

More info in these formations on wikipedia: https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

But what is even more fascinating is that people built very complex structures in Game of Life. Like spaceships, cannons or even functioning CPUs.

The answer on stack says it takes 11,520 generations per clock count (I guess it means for 1 minute)
Also that simulator site allows to set the framerate. So: (from a comment on stack)
>24 FPS with a Generation Step of 8
>24 x 8 x 60 = 11520
Should work. I don't how precise it is, and you'd need to start it perfectly on time, but it would be fun

 No.403[D][DF]

>>402
As far as I understand it, the "step" parameter is the amount of steps per frame. So with a step value of 512 and fps of 20 that is 10240 steps per second.

The Problem is, that it displays only every 512th step. If it took only 3600 steps for a minute it would show every step with 60fps (60 steps per second * 60 seconds in a minute).

 No.404[D][DF]

>>403
Sadly that can't work with the current design
>At the very top, there's the clock. It is a 11520 period clock. Note that you need about 10.000 generations to ensure the display is updated appropriately, but the design should still be stable with a clock of smaller period (about 5.000 or so - the clock needs to be multiple of 60).
You'd need to redesign the thing for a smaller display, or it would all just be a mess

Nuclear waste lasts a long time, like super long. We're talking longer than all of recorded history by orders of magnitude. Right now, the only way we know how to deal with this waste is to bury it somewhere and put up a bunch of signs that say "there's a bunch of radioactive material here, so put away that shovel." The problem is, language changes over time. English from a mere 500 years ago is nearly indecipherable to anyone without a college degree. How do we tell people 10,000 years in the future to stay away, without dedicating the resources to constantly maintain these burial sites? What if we get sent back to the stone age by a meteor impact, massive pandemic, or nuclear holocaust? What then?
The Sandia Report gives 9 messages that need to be conveyed:
>This place is a message... and part of a system of messages... pay attention to it!
>Sending this message was important to us. We considered ourselves to be a powerful culture.
>This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.
>What is here was dangerous and repulsive to us. This message is a warning about danger.
>The danger is in a particular location... it increases towards a center... the center of danger is here... of a particular size and shape, and below us.
>The danger is still present, in your time, as it was in ours.
>The danger is to the body, and it can kill.
>The form of the danger is an emanation of energy.
>The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited.
Humans are notoriously curious, so it's rather difficult to keep them out of the metaphorical cookie jar. Especially when said cookie jar is filled with the curses of ancient gods. Written language is useless, as has been covered, and word of mouth is dodgy at best. So it's down to symbols to communicate the message of "bad, stay away." These range from fairly tame, like a grimacing human face, to badass, like so-called "hostile architecture" (pic related)
So, my question to you and the purpose of this thread is, what is YOUR solution to the problem of communicating danger to future Post too long. Click here to view the full text.

I think that problems like these will sort themselves out. Say that theoretically all knowledge of the present is destroyed. The descendants of the survivors build their own primitive cultures, with traditions and taboos. People who dwell in radioactive locations will become sick and die. Stories of those peoples sickness will spread and locals will come to understand such a place as dangerous, cursed, etc.: a place to avoid. Rebellious idiots break the taboos and go there and die, and are a sacrifice to the survival of the traditions and thus to the society. And the cycle continues.

You can avoid the linguistic problem by image-idea rather then word-idea key pairs.
I would do something like this:
Put three of four statues of humans with waste
One where human is healthy, digging
One where he comes close the marked item
One where he is sick and close to death
They would go one taller than the other, or only be viewable in such a way that the sequence would be pretty clear. One other suggestion I've heard was to incorportate folk stories with clues to these dangerous places, but in my opinion people would forget the important details quite fast.
