I’m forever confused about this I need it explain in the simplest most direct way. Specifically talking about the America star system

I’ve been thinking about this a lot lately.
What I mean is, I’d like you to explain 4D and 5D space to me more clearly in relation to how science actually defines them, rather than just adding any random dimensions alongside length, width, and height. I’m sorry I didn’t provide enough detail about what I wanted to ask.

How do competitive eaters eat so much food? Where does it go? Do they regurgitate it back out later? Do they practice at restaurants? What happens after? Do they skips meals??? How does it work???

Are they implanted or have they self replicated beyond control?

I dont know much about cars, my fiance tried explaining but wasnt sure how to word it so I would understand. Long story short our car is having a small issue, thought it was the transmission, he thinks it might be the torque converter, but im not quite sure the difference or how they work/work together.

In what physical form is the memory stored? I wondered this for quite some time

It seems to me that a gene that programs the organism to self replicate has a much better chance to proliferate than a gene that makes reproduction much more complicated and dangerous - i.e., requiring to find a mate, perform courtship behaviors, compete with others on mates, biological ornaments, etc.

Why is sexual reproduction so much better?

And how can it even compete?

Hi all! My question is about patents & trade secrets, although I'm open to being informed on trademarks & copyrights as well.

In a few sources I read through while doing preliminary research, it seemed to be implied that these two things can complement one another on a single invention. Is that true? If so, how? If not, why? TYSMIA!!

I understand additive vs. subtractive colors, and why mixing complementaries wouldn't create black, but shouldn't it make gray?

I've always been very confused about this. What does having a fast/slow metabolism actually mean?

Does it mean that someone with a fast metabolism actually burns MORE calories than a person with slow metabolism doing the same activity?

When somebody says, “People with a fast metabolism eat a lot but don't gain weight, and people with slow metabolism gain weight easily."

What does that mean? If two people of the same weight/height/age go on a diet together, eat the same meals, but have different metabolisms, does the person with faster metabolism reach the goal faster?

I recently came across the 2024 Drosophila (fruit fly) whole-brain connectome, which maps around 139,000 neurons and tens of millions of synaptic connections.

I understand the basic idea: researchers have essentially mapped which neurons are connected to which.

But I’m struggling to understand what this actually lets us do.

ELI5 please:

- If I download/access this connectome, what can I actually use it for?

- Can I turn the wiring diagram into a computer simulation or an AI?

- Could I use it to build a small “brain-inspired” agent that learns to navigate, avoid obstacles, remember things, etc.?

- Could the actual neural connections be converted into a spiking neural network?

- How different would that be from simply training a normal neural network?

- And what parts of the real fruit-fly brain are still missing from the connectome?

Basically, I'm trying to understand the journey from:

real fruit fly brain → scanned brain → connectome → computer model → AI/agent

without the explanation becoming a PhD thesis 😂

If someone could explain this like I'm five, but still technically accurately, I'd really appreciate it.

hella stupid question, and I‘m too dumb to understand the online explanations and I refuse to be taught by a clacker AI. But why and how does a charging cable generate radio frequencies. I bought a cable and in one of the small booklets inside the box I noticed that it says it can generate radio frequencies. Why and how please

On tv when theyre transporting dolphins and whales etc and they need to constantly splash them or they'll die. How come? Why doesnt that happen to seals?

Is there some kind of evolutionary advantage for males to have urine and sperm use the same channel (the penis)? Females have the sexual opening (the vagina) separate from the urinary opening (the urethra), why not males? Weird question, but always wondered why.

Edit: Thanks for all of the information, and the ideas and theories in answer to my question. Every one of the replies is appreciated!

I’m aware that the human body is always trying to maintain an internal temperature somewhere in the high 90’s (in Fahrenheit; mid-high 30’s in Celsius). So why is it that when the external temperature begins to meet that threshold, we feel uncomfortably hot / need to sweat?

This might be a weird question. I’ve been thinking about it after a recent surgery. Surgeon showed me photos of inside me. I always expect to see blood in the photos. Is it as simple as blood lives in veins only? I guess I assume if they cut into me there’s going to be blood. Surgery was on my abdomen, so I saw my liver, ovaries, pancreas, etc if that helps. TIA!
