yours isnt the end all either

2019-10-28 09:26:50 UTC  

yeah i recognize its my personal preference for how to live

2019-10-28 09:27:02 UTC  

its just a more complex model

2019-10-28 09:27:08 UTC  

very true

2019-10-28 09:27:13 UTC  

and not the real thing

2019-10-28 09:27:14 UTC  

i see what you mean

2019-10-28 09:27:25 UTC  

well yes, we can never prove we have the final model

2019-10-28 09:27:43 UTC  

i think we might be close honestly. QM is fantastically good the only flaw is its not background independent like GR

2019-10-28 09:27:49 UTC  

the final model is the universe itself.

2019-10-28 09:27:56 UTC  

Nothing we can invent can explain the real model, because it would be made up of parts of the real model

2019-10-28 09:28:01 UTC  

we need a model for QM where spacetime is emergent instead of baked in

2019-10-28 09:28:03 UTC  

whats M ?

2019-10-28 09:28:09 UTC  

you can't make it more simple without cutting corners and generalising.

2019-10-28 09:28:21 UTC  

the thing is QM is ridiculously simple

2019-10-28 09:28:32 UTC  

and it works everywhere but black holes

2019-10-28 09:28:36 UTC  

M for Mexican

2019-10-28 09:29:08 UTC  

To understand QM you need nothing more than basic linear algebra, basic calculus, and abstract algebra

2019-10-28 09:29:16 UTC  

yeah but i think qm is a general idea, it doesn't account for every single action at every point in time... i understand that sentence i just made can be broken apart easily though .lol

2019-10-28 09:29:18 UTC  

but theres always deeper layers

2019-10-28 09:29:38 UTC  

can you explain what you mean by that

2019-10-28 09:29:49 UTC  

it can explain almost everything, it just cant predict all outcomes

2019-10-28 09:30:17 UTC  

basically we need better resolution at smaller scales to really see what's happening. qm is predictive, but not an exact model of reality.

2019-10-28 09:30:23 UTC  

the biggest problem is QM treats time and space as absolute, when we know theyre not

2019-10-28 09:30:26 UTC  

theyre emergent

2019-10-28 09:30:57 UTC  

we dont need better resolution.... QM is an exact model of reality or very close

2019-10-28 09:31:04 UTC  

We don't really go smaller anymore. We get more abstract to account for different cases and observations.

2019-10-28 09:31:08 UTC  

yeah VERY close.

2019-10-28 09:31:09 UTC  

JQM

2019-10-28 09:31:12 UTC  

the fuzziness of quantum predictions is a consequence of our inability to measure exact quantum states

2019-10-28 09:31:24 UTC  

and the reason we cant is because there's no operator for them

2019-10-28 09:31:46 UTC  

das tru

2019-10-28 09:31:48 UTC  

an operator is a hermitian matrix you can multiply the wavefunction by to obtain a measurement

2019-10-28 09:32:02 UTC  

das rite

2019-10-28 09:32:02 UTC  

hermitian is a fancy way of saying symmetric matrix when the matrixes are complex valued

2019-10-28 09:32:07 UTC  

tru

2019-10-28 09:32:19 UTC  

yes.

2019-10-28 09:32:27 UTC  

W = wavefunction, P = position operator. WxP = observed position of particle

2019-10-28 09:32:36 UTC  

uhuh

2019-10-28 09:32:46 UTC  

The reason we have uncertainty principle is because matrixes dont always commute

2019-10-28 09:33:05 UTC  

meaning that W x P x M != W x M x P (M = momentum operator)

2019-10-28 09:33:10 UTC  

What is the result of a quantum calculation?
