Explain Like I'm Five

How are they able to perform well under intense pressure? Literally life or death situations. I'm talking about hardcore parkour or crazy people climbing skyscrappers.

Have their brains been altered that they can't feel fear from their stunts?

I really don't have a lot of background on cluster munitions; it only really came into my perception in response to the controversy over the US providing them to Ukraine. As I understand it, the controversy is because they often don't all explode reliably, and unexploded munitions can then explode months or years later when civilians are occupying the territory, making it similar to the problems caused by landmines.

In an age where things like location trackers, radio transmitters, and other such local and long-range technology to locate objects are common place, what's stopping the manufacturers of these munitions from simply putting some kind of device to facilitate tracking inside each individual explosive, to assist with detection and safe retrieval after a conflict? I get that nothing is a 100% effective solution, but it seems like it'd solve most of it.

Can someone with actual knowledge explain why this is still a problem we're having?

so how do i post something to different instance? yesterday i posted something to asklemmy which is in lemmy.world from my account which is signed up with lemmy.one but it ended up landing on [email protected]. it will be great if someone can explain how posting works here.

They were a good indicator for notifications that are missed when you were away from phone.

I've heard a lot about this game, but I just don't know how to play it. Can someone fill me in?

I read a lot about Threads and defederation. And I only have a vague Idea what defederation is.

What is it, what are its consequences, how does it work, why is it there, why do we care about it?

With the recent Reddit stuff and YouTube stuff, I realized I've been using numerous third party apps or services. The question I have is why the decision and how such decisions would really benefit the company. As an random user, should I be worried about it or even go back to the official Apps just in case the third-party apps would be shut down in the future?

How fast did the people in it die?

Of course once the sub filled with water they would die instantly because it would reach insane pressures (300-400 ATM or 5800 PSI)

I grew up going to church but I'm not religious now and I never really understood this part.

Please, no answers along the lines of "aha, that's why Christianity is a sham" or "religions aren't logical". I don't want to debate whether it's right or wrong, I just want to understand the logic and reasoning that Christians use to explain this.

I often see that network settings have a field for logical port. What is this field.referring to?

If content on the fediverse is federated and copied to local instances, then won't instances have to hold onto a forever increasing amount of data?

(inspired by a question on reddit, I'll post a reply too)

I was watching a documentary where they were talking about a void within the great pyramid and how we don’t know what’s inside it! How come we haven’t we been in and had a nose around?

I just noticed their instance pop up in the feddit browser and they are huge and established. Who are they? Whats the vig? Should I join some of their communities or do they have a particular agenda they're pushing?

Obviously people are being price gouged, but just saying "record profits" without really being able to explain it feels like I'm just repeating what I've heard people say and not speaking on an informed level. What does it actually mean? Like before or after production and transportation costs? Before or after taxes? Raw product yeild? Something else?

I saw that beehaw.org was defederated from lemmy.world but not on lemmy.one. And I am on the latter one. What does it mean exactly?

What are the Particles and their categories?

I'm thinking of creating a community (or two, or...) but am worried about taking on a lot of work. What tasks are involved?

I know there are posts out there explaining this quite well, but I would love an ELI5 version. What is Lemmy and the Fediverse?
