Things you are too embarrassed to admit you don't understand

[ClassicStripe]

I don't think I really understand what a fascist is.

Why our sky is blue and photos from the moon or Mars show a black sky.

Think it's to do with the atmosphere, again I've had it explained loads, but I just don't get it.

@Birdfeather, affect is a verb, effect is a noun.

Climate change is affecting the weather - what effects have you noticed where you live?

Rock, paper, scissors 🫣

The very tiny but very vast scales of all the matter in the universe: if you were to pour a glass of water into the sea there are enough molecules in that one glass for every subsequent glass you scoop out to contain one of those molecules.
And then the entire universe contains hundreds of billions of galaxies.

I don't understand any sci fi or fantasy type films...or action films come to think of it. Like, they're in a random warehouse having a fight scene. Why are they in a warehouse? Who owns it? Why is no one else there? Oh someone been shot dead? Surely they'll be a murder investigation? Why is no one being arrested for it? I just have too many questions...nothing makes sense in films like this

What 'reverse' means when someone uses it in context of a post on MN!!

When the poster is pretending to be the other person in the scenario described.

For example, a mother-in-law who keeps turning up unannounced at her son and daughter in laws house. Sometimes the DIL will post but she’ll write as though she’s the MIL (AIBU to drop in on my son and without ringing first?), that would be a reverse. People tend to get annoyed at them as it’s hard to give proper advice and it’s usually viewed as a manipulation

The game of chess.

😂

That's more to do with in individual's body testimony rather than nutrition.

@riotlady

Ah! Thank you 😄

Thank you @MavisChunch29 , forewarned is forearmed😀☠⚡

No Claims Discounts - Bonuses - all a bit of a mystery to me.

How if the world 🌍 is round, how the people who live at the bottom aren't upside down.*

There isn't a Top or Bottom! The people in Australia are no more upside down than we are in Britain!

North and South are only oriented at the top and bottom on maps and globes by tradition.

If an alien craft approached Earth there is no reason why they would think our way of portraying its orientation is "right".

Get a globe, turn it in your hands in all directions. Every single way is "right". Having Antarctica on the left and the Arctic circle on the left is "right" too!

Or the fact that some planets are made solely of gas, uranus and Neptune i think. Then they don't really exist at all do they? If something bumped into them wouldn't they all disperse? Why do we pretend they are real?

And why doesn't the sun doesn't make light anywhere else? If its a massive ball of fire how is this possible? I don't think scientists really know as much about space as they pretend. It's not like any of them have ever gone there beyond our orbit.

Affect and Effect. I’ve read all the explanations here and I still don’t get it. One is noun and one is a verb but they can both be both?!?

I just use ‘impact’ if I have to. Ashamed to admit I’m a professional writer, I just have such a mental block on this.

So if I go to write the sentence ‘global warming has a big affect / effect on temperature’ I still don’t know which is right 😩.

I think I want a noun there but how the hell do you remember which one is which. Effect? Sigh.

How we can never see the dark side of the moon from earth; I know it's to do with the rotation of both planets, but I just can't picture it.

Yes, effect in that example. I can’t think of a handy way to remind yourself which way round it is if you haven’t got it fixed in your mind. Maybe someone will come along with a great idea!

@girlygirly a black hole isn't a hole or a tunnel. Imploding means to collapse in on itself and get more and more squashed together. So, like a bath sponge when you squash it hard, it has the same amount of stuff as before but now it's in a smaller amount of space. That's what happens to some stars when they get older, the stuff that makes the star gets squashed in more and more by it's own gravity until it's so small and dense. Then anything that gets too close is pulled in too, even light. Which is why they are called "black" because you can't see them, because even light gets pulled in. If light can't reflect off an object and reach us, then it appears black to our eyes.

@LaMaG gas giants are real. Jupiter has a liquid centre with possibly some small inner solid core. It's then surrounded by thick dense atmosphere. Gas is still matter, made up of atoms just like liquids and solids. Just a bit more spread out. Gas giant planets don't disperse because the gravity of all their mass holds them together, just like a solid planet is held together by its own gravity.

The sun does "make light" in other places! Light emits from it in all directions, lighting up all the planets that are in our solar system, and anything else nearby. Other star systems with other planets are so far away that they would see the sun as a bright star in their sky, like we see their stars in our sky.

How does colour and lights work?

The sky on Mars isn't black in daytime.

The Earth and Mars both have atmospheres. Looking at the sky through the atmosphere the suns rays are diffused by the air so we see blue. The Moon doesn't have an atmosphere so the sky there is black even on the daylight side.

Human eyes perceive different wavelengths of light as different colours. We can only perceive a small section of the available wavelengths of light. Red is the longest wavelength we can perceive, and violet is the shortest wavelength.

The sun emits white light, which is light waves of many varied wavelengths at the same time. It's like a choir of people all singing, but each one singing a different note higher to lower. Light bounces off the surface of objects, or can be absorbed by the object, depending on what the object is made of. Some surfaces absorb all the wavelengths of light apart from those in the red range. So only the red light bounces off it and reaches our eyes, so we perceive those surfaces as red.

I don't understand 3d printers.

"They can make anything" I was told. But out of what?? They can't make a person or a tree.

Surely they can't make anything?

I am hoping the person who said that they can make anything was talking bollocks. But it was a teacher in a school to a class of kids so at the same time I am sort of hoping it's just me being thick.

A 3d printer can print any shape object, but the object is made out of plastic. It's essentially just squirting out runny plastic that sets hard, and squirts it out in layers to build up the object.

You can get 3d printers that print out using melted chocolate....
