Can a team of surgeons safely create a human centipede?
What would be the medical complications besides the gag reflex, stitches, suffocation, and bacteria?
you can not survive by eating poop. The 2nd guy would die almost immediately, same with all the rest
>>8120630
sure you can, how long is unknown but many organisms eat their fecal matter.
>>8120638
Organisms that re optimized for doing that. Human faecal matter has very little nutritional value
I'm living in a state of constant and extreme brain fog for weeks, and sometimes I suddenly get cleaheaded for a few minutes/seconds.
How the fuck does this happen? Do I have a purely physical health issue or somethinh? Or do people with mental issues/dissociation get this as well?
The CIA/FBI has targeted you. You know too much or asked the wrong questions.
You can block the directed subsonic sound devices and microwave radiation they're using to scramble your thoughts by putting insulating aluminum drapes over your windows and wearing sound canceling headphones. Don't drink the tap water unless you run it through a reverse osmosis filter, they've probably already gotten into it.
>>8120619
The tap water part is actually good advice because the water here is shit, so thanks for the tip, but the rest is a shitpost.
How did your train of thought got you from brain fog to paranoid schizophrenia?
>>8120604
Most likely is related to lifestyle or envirement. The obvious culprits are lack of good quality sleep, incorrect glasses or contact strength, staying inside too much and not looking at far away objects enough, nutrition, social lifestyle or lack there of producing anxiety and a whole host of other stuff.
What is /sci/'s opinion on Cryonics? (better known as cryogenics, even though they're not the same thing).
Defined somewhat as "The practice or technique of deep-freezing the bodies of people who have just died, in thehope thatscientificadvancesmay allow them to be revivedin thefuture."

when u freeze some old guy and unfreeze some old guy he's still old af when u unfreeze him u better get froze when ur young and taut chop chop
Have they ever successfully thawed out mammals before?

We could go to mars now. SpaceX's rocket landing technology makes it possible.
The only thing keeping us from doing it is the lack of money and will.
thankfully Musk has both.

Is this man the worst administrator NASA has ever had?
>>8120495
It's gonna happen they are building the rocket and spaceship
As for the Europa business yes he was uninterested in Europa but Congress forced him to add a lander so there will be a lander anyway.
>>8120508
I doubt the SLS will even fly once
SpaceX will be going full speed ahead on their big rocket
Maybe Blue Origin announces THEIR rocket...
And then the SLS will be left sitting there capable of only 1 launch every 2 years, costing 5 billion each....
Yes. What a waste of 8 years.
The only good thing to come out has been commercial crew/cargo and Elon Musk will soon make NASA irrelevant.

How can we forestall the breakdown of the neurons in our brains? How can we escape the inevitable closure, stagnancy, or infinitely accelerating expansion of the universe?
Death and destruction are beautiful things because
1. without things going away, time with them now wouldn't be as precious
2. coming to terms with impermanence is an experience i wouldn't ever want to take away from someone else; i used to think i'd never come to respect it, even promoting transhumanism [no, not that trans] with religious fervor; in the end i saw that all things, including the bad [and the good] must come to an end, and there is beauty it in... you don't see it until you get sick of the bad and wish the good to rest [with the rest...

Death and destruction is nice when it's the death and destruction of things that would lead to your own death and destruction, otherwise, it's to be avoided.
The first is a tired point.
It's sour grapes. Living forever seems unlikely, so people make up ways in which living temporarily is better. I'd bet they'd forget their arguments were the grapes ever to fall.
Better to be like Durandal or Roy Batty. What fun they had trying to escape death!
I don't know, we have a lot of universes and big bangs and heat deaths to figure that out.
sup /sci/ quick question
Say the space elavator was built
The rope leading all the way down to the ground was cut and only 1 man is holding it
Since the station in orbit is in a friction less, 0-gravity Newtonian environment would it not be feasible to begin pulling on the rope eventually causing the station to be dragged back down into earth, de-orbiting it and causing it to burn up in atmosphere?
>>8120344
The cord is under an ungodly amount of tension. Cutting it at the bottom makes it fly away with the force of a thousand suns

Cashiers can go for sure. I've been using the self check-out aisles ever since they introduced them back in the 90's. Fuck people looking at my groceries.
>>8120348
I'd probably say:
2
depends on the def. of 4
9
The others the appeal is the human component or the skill specialization might not be realistic (i.e. janitors, you could get a floor sweeper but random messes/hazards you'd need someone on the job).
What is the probability of technology singularity being made in 50 years?

It either happens, or it doesn't.
Since /x/ is full of retards that believe in reptilians more than extraterrestrial life, I'll post this here. What would you do if we were contacted by sentient extraterrestrial life? How would the human race react? Would we send a diplomat to communicate with them and if so, who? Bonus points for sound and reasonable explanations
Whats the scenario and context on how we meet them ?
>>8119994
ETCs almost certainly do not exist
>>8119994
We were already contacted, senpai.
I've been revising some statistics lately, namely random variable distributions. My friend has given me some distributions he came up with and I'm trying to find the distributions of sum of variables etc.
He gave me 1/sqrt(1-x^2) and I'm pretty much stuck, because every way I know of doing this kind of problems leads me to an integral that wolfram doesn't even dare to touch.
Pic rel, I've tried the very standard method and ended up with integral that I have no idea how to solve and wolfram comes up with elliptic integrals. I've also...

Anyone? I haven't made any progress so far.
>>8119744
you can probably approximate it with some normal distribution for high enough n
>>8120218
Well, I've generated it numericaly and it's nowhere like normal distribution. More like two exponents mirrored and glued together with peak value in the middle.
What's keeping the last down quark in the proton from decaying in the same way the down quark in the neutron decays?
I imagine it might have something to do with Pauli since you'll have three up quarks with only 2 possible spin values but shouldn't the existance of color make this a non issue? They obviously all have different color.
A baryon with composition (uuu) is called [math]\Delta^{++}[/math], and it has a mass 30% higher than the proton. Hence going from proton to delta++ costs a lot of energy.
[math]\Delta^{++}[/math] commonly decays into a proton and pion though.
https://en.wikipedia.org/wiki/Delta_baryon
>>8119686
[math]\Delta^{++}[/math] also has [math]J=3/2[/math]. Is it not possible for a [math]J=1/2[/math] (uuu) state to exist, which would be lighter?
>>8119700
Considering just the spin, a 1/2 and 3/2 state are possible, but when adding in the orbital angular momentum, there's no way to maintain that 1/2 state. I don't feel like doing the math right now.
No, the lighter state does not exist.
I did a quick calculation and found that with the amount of energy it would take to convert a mole of protons to delta++'s, you could get 37,000 kg of matter to escape velocity on earth.
You need an accelerator to make these particles.

It's fucking craz, they have created the "god particle"
Everyone knows that Aliens "fallen gods" created the human race for the purpose of a working slave species to mine gold since the beginning of our history. Gold is the best conductor and resource for them. Think of kings and rulers, why were they all so obsessed with gold? "The gold is for the gods"
This is a more advanced portal for them transfer things they need to different "dimensions."
