Schrödingers cat is an observer and his thought experiment therefore doesn't make sense at all. The cat is dead the second the atom decayed, because she observes her own death.

Just kill the cat and be done with it.

cat is another dimension, dead in ours?

maybe schrodinger was one of those morons who believed animals arent conscious
who knows

>she observes her own death
"Observer" has a different definition in science than a conscious entity and the fact that you don't know this means you shouldn't be here

Why does it need to be a cat? Might as well use a dog or literally any other animal

Schrodinger imagined this experiment because at that time he didn't believe in quantum mechanics and wanted to show the absurdity of it.

Why the fuck popsci faggots are so obsessed with this shitpost mental experiment

All that stuff with observer is just experiment on brainwashing, nothing to do with physics.

That's certainly a metaphor for sub-atomic physics. But I'm no scientist so

Cat dies the moment gas is released, gas is released even without observer, because trees fall in the forrest even if nobody looks. It's philosophy. In physics shit doesn't change by observing, only by means of observation. E.g. some measurement changes the system.

Schrödinger was just trolling, taking the observer’s paradox to an extreme to make a silly point. At no point did he actually believe a cat can be alive and dead at the same time. You guys just fell for it (and every high school teacher)

[Anonymous No.12136209]

EVERYONE: please actually learn QM and the math and the experiments around QM before posting this shit.
The reason QM is considered weird is NOT BECAUSE of some misunderstanding of any thought experiment or anything like that. It's because the empirically observed behavior of particles makes no sense under any classical view of reality.

I am a layman. Please tell me if this description is roughly accurate. Basically the way I understand it is that, at particles seem to behave in strange and unintuitive ways at the micro scale. I read a metaphor like, "imagine if when boiling a pot of water, it didn’t gradually begin to boil, until a specific temperature is reached, and then it begins boiling all at once" or “imagine baking a cake, and instead of cooking slowly, after exactly 2 hours elapse, it goes from ingredients to being a finished cake”. Basically, you would expect things to behave continuously as we see at a macro scale, but on the micro scale we see things happening only at discrete energy levels.

Is this somewhat accurate? Or am is this just total BS I’m spewing?

if you're dead, how can you observe anything?
if you don't observe anything, how can it collapse out of superposition?

I subscribe to the Primary Observer interpretation.
In about 10 years we'll be able to conduct an experiment to see who the Primary Observer is.

>ITT: People who don't know what an observation or observer is in the context of QM.
Oh my god and I thought I was stupid, this board really is filled with retards isn't it?
An observation is a measurement, not just "lel conscious being looked" you /x/ tier dopes.
Shrodingers cat is a thought experiment on superpositions before observation.

The experiment was created to make fun of quantum theory, he thought the idea was retarded and impossible. People latched onto it because cats are cute.

PBS Spacetime is pretty great

[Anonymous No.12141127]

>>12136736

You're pretty accurate in your assessment. Basically, on the macroscale, we experience spacetime as 3 orthogonal spatial dimensions and one mutually orthogonal time dimension. This is intuitive.

On the microscale, spacetime is more entangled, so you get 7 rows on the periodic table (only 3+1=4 row sizes though) - its all stretched out.

some stuff in modern quantum theory is wrong though, like the correspondence principle, quantum systems can be any size, they aren't restricted to the microscale.

the experiment is talking about how the cat and the poison are an entangled system with a probability amplitude associated with that system's outcomes, and that measuring the system relates to the observer becoming entangled with that system, but with an updated density matrix. This update reflects the probability of the cat being in a given state, given the newly entangled system of you and the cat system. The point is that before the cat is measured, it is in a linear combination of states with a given probability amplitude associated with each state. After it is measured the cat system has an updated probability amplitude associated with those states. As you can imagine it is impossible to know what state the cat is in without observing it. Whether or not it is dead doesn't affect the probability of it being dead before you measure it.

You might have a vivid imagination but it isn't worth much if you don't actually try to learn anything to feed it with. Science is largely about developing standards of tests that can reliably eliminate falsehoods, not searching endlessly for things to support your beliefs.
