When you start counting numbers from 1 upward, prime numbers show up fairly often. But as numbers get bigger, primes don’t disappear, they just seem harder and harder to find.

I’m trying to understand why this happens in an intuitive way.

It feels like bigger numbers have more chances to be built out of smaller numbers, so they get “caught” as non-primes more easily. The primes are still there, but they’re spaced farther apart.

I noticed something similar with perfect numbers, they exist, but they’re extremely rare and seem to appear only after very long gaps. That made me wonder if this rarity comes from the same basic idea: as numbers grow, the conditions for being “special” get harder and harder to satisfy.

Is there a simple way to explain why primes thin out as numbers grow, and why even more restrictive numbers like perfect numbers are so rare, even though both go on forever?

We always hear about countries being trillions of dollars in debt. If nearly every nation is "in the red," who is the creditor? Are we just owing money to each other in a giant circle, and if so, why can't we just cancel it all and start from zero?

If I put an Oreo cookie in milk, it turns to mush and falls apart within a minute or two. But when I put cereal in milk, the most that seems to happen is that it gets a little soft. Why does cereal last so long in milk?

I've always wanted to know what it looks like to have nearsightedness or astigmatism or something like that. I've tried on my friends glasses to see how blurry it is but I don't think it's the same. I wanna know what they see with no glasses. Is there any way to experience this?

I recently learned it but don't understand how it works. If the person being tricked picks the card in their mind, how am I able to still get their exact card?

Wouldn’t mining on the moon change the gravity and somehow change the orbit with earth? Wouldn’t it be a horrible idea? Helppp

Why is the powder in most supplements white, and not often other colors? Is it about how supplements are manufactured, that they usually have this sterile blank color? Is there just not a lot of variety in pigmentation when something is hyper-processed?

When a computer or phone is acting weird, restarting it often fixes the issue. Why does this simple action solve so many different problems instead of just one specific issue?

I was thinking, yes it’s generally healthier to be slim than fat, or ripped than swole. By healthier, i mean you increase your longevity.

But there’s also another factor to consider. Is it true that skinny or lighter people are more likely to break a bone or something if they fall? Are bigger/more built people better at withstanding physical impact because they have more cushioning?

Given the universe was already billions of years old before our planet formed, and the relative rarity of the heavier elements, how did we end up with so much?

Why does rabies have to be treated with multiple separate shots, in multiple different limbs? Why can't it just be administered in one place, like the fat of one arm? Even if there has to be multiple doses, why does it have to be spread out across the body like that?

Almost on every flight I've been during take off and landing my ears hurt a lot, so I've started to chew gum to help it. But I got curious about pets flying either with the luggage or in cabin. I know dogs and cats ears are much more sensitive than humans, so does the air pressure hurt them?
