no, it's the opposite. suffering from famine increases the chance that your children and grandchildren will suffer from obesity and related ailments:

it makes sense if you suffer a famine to turn on epigenetic markers for storing more fat …

Yeah the guy I heard was talking about a study done in a Swedish town. It's probably different for men and women enduring famines, because lipid metabolism is quite differently regulated.
This article talks about when the women experienced famine that were pregnant. So this is essentially talking about epigenetic changes of a fetus.
There's a difference when we're talking about a female or male fetus though. Eggs are formed early for females, while sperm only start being formed during puberty.
Maybe the guy quoted a study that has been debunked by now, I don't know. I'm too lazy to go figure it out, but the "it making sense" part is only a naive take on how things can be controlled. I could say the same thing and go: "but famines will leave their mark for a more tightly and better control in energy metabolism, whereas an already unhinged individual (obese person), will leave their mark for an unhinged system"
I bet it's different for different eras, sexes, environments and probably even (sub)populations.
Said my bit from the last part of this video; quite interesting nonetheless, especially for people not knowing a lot about the field (it's been quite over-dramatized still though)

the "it making sense" is not "naive" when it's a post hoc rationalization that is in agreement with scientific findings. i understand your reflexive feeling that it must be more complicated than that, and it surely is, but i submit that your "better control in energy metabolism" makes no sense.

Can the earth collapse? Why or why not? Is there any risk of the earth collapsing from humanity?

How can Earth collapse when it's flat?????

I suggest we create a machine that neutralizes electromagnetic forces. I think that should be enough to collapse earth (maybe not into a black hole, but into something very small and dense).

The question is what exactly do you mean with "collapse". If you are talking about literally breaking apart and compacting, then no, not under any normal circumstances. You would need to either add absurd amounts of mass from somewhere, or disable/change some basic forces in nature. None of which is currently something that humanity is even close to being capable of.
If you are talking about something like "The ecosphere collapsing" you have a completely different question.

Posting from one of the sister sites (Liquiddota for example) in the shared forums (Community for example) doesn't increase your post count when seen from the main teamliquid.net site.
If such posts are then deleted I guess you can go negative?
That or voodoo magic.

So now that I'm not too lazy to figure it out anymore, I have the following to add: the Överkalix study (the one I tried to make a general statement about) seems to have different outcomes that the Dutch famine study.
You rationalized on a specific study and I, falsely generalized on a specific study and tried, in my response, to rationalize the specific different study.
I think that in certain situations, people'll will live longer, less diabetic lives due to certain epigenetic changes (or small mutational effects we aren't aware of), which exert a better controlled energy physiology (or maybe their diet is overall simply healthier and more nutritious making them less exposable to becoming diabetic) and in certain situations, because of the Dutch famine for example, it'll lead to offspring dying faster, having more risk of cardiovascular disease and being more prone to becoming diabetic.
At the very least they're peculiar findings. An interesting review on the topic at hand, if you're intereted. The part on human observations is a good read, but doesn't cover certain studies fully, nor is it exhaustive.

I guess what I would mean by a collapse is the crust somehow going into the mantel. Something like a rift valley not having enough support under it and the crust just kinda gets fucked from it. (Does this make any sense?)

You would need the core of the planet not having so much pressure exerting on the outer mantle, literally not being able to help itself but barfing out material, and being hollow so that the weight of the outer mantle is too much on the inner mantle. I guess? Don't know how sound this is physically, but it's nothing more than speculation on my part.

That can not happen. The earth is generally mostly sorted into levels of density. This is the case because most of the earth has been liquid for most of its existence, and the same thing happened that happens when you put oil and water into a glass and shake it. It sorts itself by density. (This is also the reason that most of the iron on earth is in the core, because it is very dense when compared to most of the other stuff that earth is made of)
The crust is the least dense, and thus it "swims" on top of the mantle. Locally, stuff like that can happen, mostly through one part of the crust pushing another under (Like how you can make ice go under water by piling more ice on top of it). But globally, no. Think of the earths crusts less as being held in place by being a stable empty sphere, and more like ice floating on top of an ocean. The water can sometimes break through, but the ice will overwhelmingly stay on top.
What could happen is that all of earth is molten stuff, but for that to happen you would need a lot more energy to be put into earth in some way. Earth was that way for the first billion or so years of its existence, but then it had radiated off a lot of it's energy into space, and thus cooled down a bit.

Will the core keep spitting out stuff, or will it eventually have expended all the energy/expelled all its matter and become a solid?
|
Eventually, earth's core (And mantle, and everything else) will become solid. The core stays liquid through a combination of being pretty well isolated and thus not emitting a lot of energy into space, and gaining heat from radioactive decay of stuff. The latter is a limited source of energy, we don't get enough energy from solar radiation for earth to be liquid. Thus, earth will eventually have exhausted its energy reserves and solidify.
I have no idea on the timeline on that though, and on whether that will happen before earth gets vaporized by the sun becoming a red giant.
What do you mean with "spitting stuff out"? Volcanoes? Those have nothing to do with the core, they are purely mantle based. And they don't have a large impact.

What channel is the gorilla channel on?
|
To be honest, i don't think that a gorilla channel would be so bad business. Just buy all of the gorilla docu's you can find, and loop them on the gorilla channel. Thus, whenever someone over 50 who doesn't use the internet wants to see gorillas, they turn on the gorilla channel. It is kind of like turning TV into netflix by producing myriads of different channels, so people can choose what they watch without having to deal with modern tech that they find scary or weird or unnecessary.
Have a gorilla channel, a Star Trek channel, a cars going fast channel...
(Also, i hope that you are aware that the gorilla channel thing was satire? It gets hard to tell with Trump, but some things are still not real)

Let's say I was on a bike and I was being pulled by a turbo charged speed car with ultra powerful jet propulsion engines. How fast would I have to be going if I let go of the car and launched myself off of a 45 degree angle ramp and i wanted to fly into space. The bike and myself weigh 250 pounds because I have a heavy duty space suit on to stop myself from breaking apart. Edit: im at average sea level for earth whatever that is. 2nd edit: changed the angle of the ramp.
