Where does random derive?

maybe consciousness ?...not sure. maybe its justa figment of our commingled brains lol !

figment of the imagination................ is where heliocentric theory derived................ and shall forever reside.

The question of where quantum randomness arises is rather deep.  We can imagine there is some place - necessarily outside of space and time - from where the randomness arises. We could also imagine that it has no source, it just is. But these are very obscure philosophical questions.

For many sorts of commonplace randomness, we can see where the randomness arises. But it pretty much any physical system, QM is at the bottom,

Eg a great source of randomness is to apply a digital-analog convertor to a very precise thermometer and observe thermal noise. The least significant bit of the temperature will be very random.  Doing similarly with many physical observations will also work. Eg radio noise from the Sun. Or the Cosmic Microwave Background. All have very pure noise in their fine-scale variation.

If the earth is actually not moving anywhere ........... where is randomness then? 

Avatar of Elroch

Everywhere.

And all motion is relative. That means it only makes sense to say something is moving w.r.t something else.

Acceleration, however, is absolute.

pick a atom out & try2follow it - its kinda fun !...Brownian Motion

...i slowed it down some...here:

...tho now it looks kinda choppy - o well.

looks like heliocentric theory to mewink.png

Theoretically no but mentally yes because why would you suddenly think of that or do that or whatever in your head mentally it’s random but mathematically or theoretically no because everything has a meaning and everything has an explanation so no
Avatar of czechsalmon
Like #7 has a meaning it’s to explain the mental randomness by talking about something completely off topic but it also has a explanation that’s it’s "random" and this forum is asking if it’s real and he think so because it’s "random"

random/happenstance ......what's the difference? 

Avatar of czechsalmon
#8 it’s not because theoretically you say something what might make sense somewhere in the universe because the universe is infinite what = to infinite patterns making me typing this exact thing and every single think to ever happen to humanity was same "theoretically if the universe is infinite" and so that means also infinite worlds of what you said was true
Avatar of czechsalmon
But of course we’re not in physics or math class so I’m gonna say it’s true because more people use the "mental randomness" just like me I also use it more so technically yes
Avatar of czechsalmon
This question is really opinion wise

Actually if the universe isn’t infinite but it’s infinite old it still counts because that means it’s contained and in billion years it will kinda explode and reform himself all new like if you put an apple there it will be rotten soon but in a billion years it will be nice and red again

finite/infinite ........bedazzling man from birth to death.

You talk about infinity so did I do I don’t know if you’re talking "randomness" or I just don’t understand

no apology necessary. 

if something is random, say like the stars, how did they decide the distances? 

factually or theoretically? 

Avatar of Elroch

It is a philosophical question whether the question of whether the Universe is finite is a scientific question or not!

The reason is that while it is conceivable that it could be experimentally determined that the Universe is finite, it is inconceivable that it could be determined that it is infinite in a finite time. So at any time the most you can know is that the Universe is "bigger than X". Thus as a hypothesis it could never be checked.

However, a counterargument is that there are many scientific hypotheses that are only ever checked in one direction. Eg the hypothesis that the fine structure constant is constant can never be proven. Rather it just gets failed to be disproven. So the hypothesis that the Universe is infinite can have that status - consistent with the evidence and never disproven.

If the arrangement of your living room is random, how can you measure distances?

Your question makes no sense. The distance to relatively near stars is determined by the surveyor's technique of triangulation. And it works well.
