Assume there's two 2 year old kids, 'A' and 'B'. A lived their entire childhood with only their parents. And B lived their entire childhood with a joint family which includes their parents, grandparents and their uncle aunts. Will their word learning rate at the age of 2 will be different and how much different?

Can the COVID-19 have enough variants where it would be considered something new/different and not be detected by the current tests? How do the tests not detect other types of coronavirus?

What's outside the universe?

Posted: 31 May 2021 03:09 PM PDT

So firstly im just some dumb 17 y.o with a question, and the question is... So space between all the objects in space is a vacuum of nothingness or spacetime or whatever but what is beyond that, that the universe is expanding into. Is there no space no time laws of physics???

[Economics] If a country adopts Basic Income what, if anything, prevents inflation or the markets adjusting the prices so that the spending power of the BI reduces to pre-BI level?

Posted: 01 Jun 2021 04:29 AM PDT

If everyone starting tomorrow in a given country would start getting $2k every month without providing any additional service or products wouldn't that lead to massive inflation?

And if there is no inflation, what's to prevent the spending power of those $2k dollars to remain stable? What's to prevent a landlord from raising rent now that people have more money? Or shops selling things at a higher price now that their clients all have more cash? Wouldn't it simply mean that after a couple of years the $2k is basically worthless in terms of spending power bcs all prices re-adjusted to everyone having more money?

What is the difference between aquatic and terrestrial plants?

Posted: 31 May 2021 08:03 AM PDT

Whats the difference in, say, cell structure between a terrestrial and aquatic plant? There are a lot of plants that can grow in water and above, but their leaves/appearance tend to change depending on their conditions.

Electric currents travel through water, so could electricity travel through water droplets in the air in a thick enough fog?

Posted: 31 May 2021 10:28 AM PDT

I was influenced by the film The Day After Tomorrow as a kid (ooo Daddy Dennis Quaid) so I've always enjoyed thinking about theoretical environments capable of extreme calamities.

Would moisture levels in the area become thick enough to where humans couldn't breath before electricity from a lightening bolt is able travel through the surrounding environment?

Chemical that reacts with Rust to ‘seal’ a surface?

Posted: 31 May 2021 12:28 PM PDT

Has anyone come up with some type of sealant or protectant that can be applied directly to a rusty surface and the chemical actually reacts with rust itself to create the sealant? Whereby the rust itself can be converted to something better? Iron oxide must have some "potential" to it and not need to be removed every time?

Can ocean sediments freeze?

Posted: 31 May 2021 01:15 PM PDT

I'm asking this because in some areas of the ocean, the bottom sea temperature can reach negative temperatures, but I never heard of sediments in these region being frozen (unless it's permafrost), does salty ocean waters prevent it from freezing?

Are COVID vaccine actually 100% effective against severe/deadly infections?

Posted: 31 May 2021 04:50 PM PDT

This CDC page says that 2% of breakthrough covid infections resulted in death and 10% hospitalized (which is not all COVID related but 70% of the 10% are, so 7% I guess).

While the numbers are minuscule when considering the whole vaccinated population who will hopefully continue to be uninflected at all, the vaccines are evidently not 100% effective against severe/deadly infections. Or am I missing something here?

What's the difference between Sputnik V and Sputnik Light vaccines?

Posted: 31 May 2021 11:21 AM PDT

Anyone know how the Light version of the Russian Sputnik vaccine works?

How is it different from the regular Sputnik V?

I literally cannot find any info on this. (beyond the fact that it's a single dose and allegedly has a 79.4% efficacy).

Reference: Russia approves one-dose 'Sputnik Light' Covid-19 jab

Being that nerve damage can prevent fingers from pruning, would fingers from a deceased body prune when left in the water for an extended period of time?

Posted: 31 May 2021 12:10 AM PDT

I was watching the case of Samira Frasch and saw that they said the body wasn't in the water long enough to prune their fingers. What prevents this from happening to someone with nerve issues but still allow it to happen to a body postmortem if it does?

What's the half-life of a breath of oxygen in the blood?

Posted: 30 May 2021 08:30 PM PDT

If a breath of oxygen could be tagged and monitored in the blood stream, how long would those specific molecules last? Does each breath get immediately used or are you just refilling a small bit at once?

Why does epigenetic reprogramming occur during embryogenesis and gametogenesis? What’s the purpose of erasing those marks?

Posted: 30 May 2021 09:37 PM PDT

I understand that they occur in these to stages, but why in each stage? How do females deal with epigenetic reprogramming during gametogenesis because of meiotic arrest? Why (in embryogenesis), does the paternal epigenome undergo rapid demethylation? Why does the female epigenome undergo more gradual change?

Also, if you could link any papers that I can access, that'd be great. Thanks in advance.

Is everything possible in a multiverse?

Posted: 31 May 2021 12:52 PM PDT

I'm just bored, so I want to tear down one big scifi cliché.

Suppose there's a multiverse with infinitely many universes that are somehow different, whether it's a little thing like at one time an electron was a centimeter further away than in the next universe or maybe completely different laws of physics.

My question is, is it really true that anything is possible?

Think of the silliest scenario you can think of and according to the multiverse theory (the one from scifi) there is a universe where this scenario has played out.

For example, there is a universe where Hitler won WW2 or a universe where someone actually likes pineapple pizza... yuck.

And now it comes... In that case, shouldn't there be a universe where people have learned to travel in multiverses and by sheer coincidence they've made it to my universe and even my room, and 10 seconds from now. 10... 9... 8...

Hmmm, no one's here. Whatever the obstacles to multiverse travel are shouldn't there be some universe where humanity has been able to overcome these obstacles? Why isn't there a smattering of travelers from different universes.

Don't take this too seriously I'm just interested in the answer and I know absolute shit about physics.
