Focus on this more. I'm not saying you should be masturbating - however, not even having the urge at all should be something that means something. It may benefit you to get a medical consultation.

Remember, I'm not saying that masturbating is either healthy or unhealthy, what I am saying is that not even having the urge at all - is not a sign of a healthy developed body.

Look around you. Everything is impermanent, ever-changing. Change itself seems to be the one and only true constant in nature. Why would the universe be an exception? It will change its form so drastically that it will be unrecognizable to what we know today as "the universe". It will effectively "end". But maybe something else will come in its place. And maybe just maybe, we'll become smart enough to survive all the way until this happens. This to me, is as close as you can get to "meaning" in the universe.

What steps would need to be taken to minimize health problems when genetically engineering catgirls for domestic ownership?

Quoted By: >>11139827

Pretty sure any human hybrid will be looked down upon.
So in terms of health problems is that if the state coming to nab you for human trafficking.
In terms of genetics, most domestic pets that have gone through years of domestic breeding have redundant rDNA segments . Dogs have a ton of these. Which makes them suitable for massive changes in breed phenotypes.
Hybridization comes with lot of unforeseeable genetic problems. Even if the resulting hybrid is viable to gestate it may be severely deformed.
Something like a cat girl would need Supreme fine-tuning of genetic code. Which is outside of our capability right now. And if our fine-tuning becomes that capable then health hazards would be minimized by virtue of understanding what the genetic material does.

>> No.11139206
Quoted By: >>11139211

you dont seem to be fucking up? the absolute simplest way is:
count the number of lines and dots sticking out of the element, then do valance number - number of dots and lines, AKA more lines and dots = more electrons, or more negative charge.

For oxygen its 6, so if you have a single bond and 3 lone pairs, you end up with 3x2= 6 dots and 1 line, so 6-7=-1
-O :

So, depending on the molecule, its can often be favorable to double bond it, then you lose 2 dots and gain 1 line, for a net loss of 1. Bringing the FC to 0.


when you have positive central atom, (try doing (SO4)2-, you will end up with a +2 central S and all around you get -1 Oxygen. When that happens, you reduce the number of FC by creating 2 double bonds (S is an exception and can exceed octets), then you get 2 double bonds and 2 single ones, or two negative oxygens only. thats the best structure because O is the most electronegative, you only have 2 formal charges (as opposed to the previous 4), and those 2 charges are very small in absolute value (1)

>> No.11139211

essentially, to save time, when you have a positive central atom with negative Oxygens or another really electronegative element (Fluoride for example) you will simply "pour" electrons into the center bounds until the center is neutral

FOR so42-:
You get a bond order of 1.5, if u dont know what that is yet just ignore this

NOTE: only if the central atom is above 3rd period (is an exception and can exceed octets).

I a village of 200, that is going to take 12500 days, or little over 34 years to repay. It may be perfectly reasonable not to do that.

In a town of 20 thousands, it will only take 125 days, or four months to repay. By all means y9u should do that.

in a city of two million, it's goung to repay in less than two days, in fact you may be tempted to spend considerably more to get the results faster.

How about something that takes $100 million to invent and saves 10 cents each day?
In the village, you can just forget about that.

they can't. A mile tall human would die instantly. Blood pressure at the feet is high enough to burst the skin to say nothing of the difficulty for the hear to pump it up to the brain. Even if we use fucking magic here, it is unlikely they will be able to run. This is because the ground surface pressure should be so high that they start to sink. This is even more the case when running. When we run we are really just hopping from one leg to the other, which would make surface pressure much higher.

I'm pretty sure the arrow is meant to point to the curved line, and not to the area/volume of space labelled R3.

Average the max and low score and add 7 points for the final result. Example: 130 max and 120 min=125+7=132 = your range is Between 127-137 with 95% confidence.

*The 7 points added are due to the webarchive version lacking the adaptive feature the original one had, so the scores here are deflated.

The top tier scientists have on average IQ in the top 0.8%.

Did you take official IQ test ?

I'm actually surprised by the relatively low spatial ability here, even nobel prize theoretical physicists had on average only 130 spatial IQ (reduce 16 points to convert to stanford-binet 1986 scores).

how did you answer the Qs with the large boxes? Like 2 large 1 small and then 2 large and so on

our observable universe and the anomaly known as gravity is the result of saturn.

saturn is a natural particle accelerator, continually running and causing high frequency false vacuum collapse incidents (estimated at at least 72 trillion times per second) for the past 14 billion years.
our entire existence and all matter in the observable universe is just a hologram caused by our existential radiation 'surfing' the wavefront of the high frequency false vacuum collapse
gravity is a result of the 'pressure' like what pushes a surfer down to his surfboard on a wave for example. our entire universe is enconded on an incredibly thin layer riding the surface of 'a' high frequency false vacuum decay incident.

due to the inverse square law, the suffering is multiplied exponentially at every second, with trillions upon trillions of souls being tortured right now if a god ever existed, its reasonable to think he was lost long ago to, many trillions of generations back.
probably before we were holograms in the first world i bet god exists.. lizards will be mad (they love the high frequency life), but i think the only option now is to nuke the rings of saturn or saturn itself to at least try and stop it but we will all die sadly.

discovered this myself by remote viewing and hoping trump and tucker carlson will see it, (i call it the high frequency false vacuum collapse theory).
interested in any links about saturn being a particle accelerator too. feel free to spread around if you want.
