If there are an infinite number of universes with an infinite number of possibilities does that mean there is a universe where Christianity is accurate and factual?
And does /sci/ believe in the Boltzmann brain theory?
>"A Boltzmann brain is a hypothesized self aware entity which arises due to random fluctuations out of a state of chaos."
No. Mathematical infinity does not invite absurdity. There are infinitely many odd numbers, none of them are even.
The Boltzmann brain theory is retarded. Life is cosmic orders of magnitude beyond cosmically unlikely. It takes more than "random fluctuation and high chaos" to form a sophistication of structure that is able to be functionally aware of itself. No matter how many fantastic-sounding nonsenses you throw around, abiogenesis and evolution are laborious and gradual processes. They don't just randomly happen all at once because you don't understand...

How does this make you feel

there was an attempt.

Feels just fine to me
Alive.
Please explain how existence can come from non-existence. I'll wait. Oh wait, that's right. It's completely impossible and is just as dumb as trying to debunk determinism.
Non-existence, by definition, isn't a place or a thing. So how the hell can existence come FROM a PLACE that is non-existent? Non-existence is a concept of the human mind and nothing more. Non-existence, by definition, has never existed and will never exist. There is no non-existence pre-birth, and there is no non-existence post-death. There is only the conceptual non-existence that...

Who says it did?
The big bang was not the creation of the universe, it was the beginning of the expansion of the universe.
>>7667968
So what do you suppose the nature of meta or semi physical such as phase space or spin would be involved in non-existence OP?
Just curious how such would fit in to your synopsis of the semantics of nothing
>tfw you get a problem wrong on an exam because of some elementary math error
Is there a worse feeling?
>>7667887
Knowing you're in way over your head but you have to keep going to the class to keep up pretenses and it feels like you're drowning but you don't know what you can do about it.
>>7667887
>making elementary math errors
No I do not know this feel
Knowing that you will live for only five years is a pretty negative feeling.
Hello, science people.
I have a difficult problem to solve and I know nothing about that kind of science so...
I have a heart "disease" ( https://en.wikipedia.org/wiki/Brugada_syndrome ) which means it is excpected to stop earlier than most people. BUT. I am actually absolutely impatient for that thing to happen for numerous reasons.
Problem, it is unacceptable for my death to be considered suicide.
What medecines or drugs should I acquire and take to just make it so that people think " Ok, so he had a Sudden unexpected death syndrome, his heart just stopped."
Please, help me.
I couldn't thank you enough. But I would try.
Wiki link says that death caused by the syndrome is very sudden.
Congrats! You have a method of dying that will be quick, less painful than many and not considered as suicide. If you can find a way to make yourself happy with dying and also happy with living, you'll have all of the man existential problems in a life like ours completely sorted out.
Learning to be happy with both life and death is, of course, the rub. Since you are good with the latter, I suggest reading various philosophies to see if you can find a way you like of living.

Oh.. I have that book by Camus... I never finished it.. I'm going to, while waiting for other answers but thanks for your time and advices.
Bumping. I wish you well OP.
ITT cool scientific technology
looks like a piece of shit granted,
but still remains the only vehicle ever designed and built to land on another world.
>>7667830
Absolutely not true, the many varied Mars rovers come to mind (specifically their landing platforms). Next time specify manned landers.
>>7668024
Don't be problematic. You know what he meant.
Who gives a fuck about rovers.
whats the difference between meth amphetamine and adderall?
>>7667819
adderall is amphetamine, not methamphetamine
>>7667823
is one just stronger?
>>7667828
Yeah, but by like, a lot.
So, for my Advanced Physics course we were assigned the project of building a device that could launch a tennis ball. They will be scored for accuracy and distance, and it is a competition. What I'd like to know from you guys is how many different ways there are to propel something, such as a spring-powered mortar-style launcher or torsion-powered swinging arms as in pic related.
I like to hear what you guys know of.
Two motorized wheels squeezing a ball out like a fat man shitting out a few hamballs she had for din din.
>>7667822
Yes, I hadn't thought of that one. Any more?
>>7667806
you could always go for a good old fashioned cannon, chemical propelent works anon

What determines the color of a molecule? What determines if a a pure element will be matte or metallic?
something about the distance between the electron levels
so conjugated systems (shit with double bonds) usually have lower energy levels, that allows for electron transfers of the appropriate energies to correspond to visible light
Speaking with 1 semester of Chemistry background
>>7667540
You're basically right. Essentially for light to be emitted an electron needs to go from an excited state to a lower energy state. The released energy will be in the form of a photon. A heavily conjugated pi-bond system will have smaller energy difference between the highest occupied and lowest unoccupied orbital (energy level, essentially). Some of them are low enough to be in the visible range.
As for shiny vs matte that's a tad bit more complicated, despite involving less QM. I'm not 100%...

So something like biphenyl won't have much of a color because it has many pi bonds, but a diatomic molecule pair of hydrogen or chlorine will?
sci, i do not understand what's going on there

Will solar energy ever be not shit?
Yeah
Probably.
>>7667471
Depending on what you're trying to do, it's pretty non-shit now.
What determines when an element will turn into different states of matter?
>>7667470
temperature and pressure
>>7667470
enthalpy and entropy
>>7667476
What determines what temperature and pressure it must be to change?
What are the best fractals you've ever seen?
Posting some OC. I remember when I used to be really into them before realizing that they pretty much all blow chunks
Only the fractals I saw on high dosage shrooms trips were the most beautiful ones.
>>7667422
There is a lake near here which always reminded me of the images of the Julia set. So one of those two fractals.
>>7667422
Also the red one is clearly China, and the yellow one is clearly Russia. Well done commie OP.
