What can't you wrap your head around?

[RosieLemonade]

For me it's how colour works. The whole part with reflecting light. Just how can that be true? (I know it is)

Another one I cannot wrap my head around is the doors in the Labyrinth where one lies and one tells the truth.

I've looked at all the explanations and I still don't get it.

She asks the door if he would say the other one would lead to death (I think) and gets the right answer from that. Goes right over my head.

That you can capture time with a camera. Something as abstract and intangible as the passing of time and yet we can stop it and have pictures of that particular moment to look back on for years, decades to come.
I know the above sounds very obvious but if I just stop to think about it it just seems like it shouldn't be possible somehow!

Crypto currency. Why is a bit of code worth something?
Why do people have different accents?

@SquirrelFan you've just made my day! I thought it was just me

Dobble. How can there only ever be one match?

Money.

It makes no sense at all and frequently baffles me.

We have lots of bits of paper and metal, and some can be used to buy things, because we all agree to make-believe that money exists. And it's not even physical stuff anymore. Imaginary money, mere digits in bank accounts.

How we now know we can time travel and we will do so in the next 100 years on a scale unimaginable.

@0blio i think they're referring to people who have multiple personality disorders.. (Sorry not sure on the current correct term) i know they refer to themselves as 'Systems' and the major personality in charge can shift/change depending on the day/mood/whats going on in life.

I'm assuming they're wondering how people like that can keep track of the myriad personalities that manifest.

YES

Also @TeardropsFallingOnHotSand whaaaaat?? Time travel is possible? 🤯

Dogs. It blows my mind that little furry things that are a different species to me are able to show me SO MUCH love and affection, and how much I have grown to love them. They take so much in and understand so much, when I'm happy and when I'm sad, they have a way of communicating with me, they show happiness and joy when I laugh. Dogs are so utterly awesome, I look at mine with so much wonder.

The multiverse. It terrifies and excites me in equal measures when I think of its infiniteness

How can dogs recognise different breeds as fellow dogs, even from a distance. But even if a cat looks more like them they know it’s not a dog!
DDog looks far more like a ginger cat, then a Great Dane, but cats freak him out!

That we keep other creatures as pets. It’s very sweet & I love pets but no other animal on this planet keeps other animals as pets

How a woman’s body can turn a little bit of liquid sperm into another human being. I mean, that’s the cruncher right there!!!!

The afterlife and how I believe the universe is connected to it.

And that everything largely knows what to dom. I have a DS with extra chromosomes and a congenital defect cos the coding went wrong but really it's a miracle it happens so little

@Terrazzo

Yes time travel is possible. It has been accepted for many years now. Simply travelling into space does that and we are on the cusp of people travelling to Mars and a sling-shot around the planets to a planet the other side of the Sun. When they come back time will have travelled more slowly, but the difference will not be material. But when and if we can travel to another solar system, let alone another galaxy, we could wave goodbye to our grandchildren and meet them a few years later and while we may not age at all, they will appear like our contemporaries.

Wow, I've never heard of that, thank you @Batsy, that's fascinating.

@BoredNewsOfTheWorld I'm bilingual and I switch between both languages when I'm thinking, depending on which language I've been talking/reading more in that day.

I'm blown away by all the things mentioned in the thread...the universe, time, how we start life as cells and then become a whole person etc.
Another thing for me is paintings. Like when you're looking at old masters paintings in a gallery...it blows my mind that someone sat in front of that canvas and painted it all these centuries ago, and I'm standing looking at it now. And in their day the world looked like what's shown in the painting e.g. the clothes, the horse-drawn carriages, the furniture...to us it all looks so old fashioned but to them it was what normality looked like.

Same with old books...I'm reading someone's thoughts from, say, the 19th century, but that person is long gone. It's like time travel, reading the descriptions of what the word was like, described by someone who was actually there.

@peachgreen

Death. I don't understand how people can be here and then just... gone. DH died 8 months ago and I am still completely baffled as to how he's not here any more and never will be again.

Have a google of Dr Peter Fenwick.

When I see a newborn baby with hair and nails etc, I can’t believe the mother was walking around with that fully formed person inside her! It just seems so bizarre.

@whatsat Read Sapiens - A Brief History of Humankind by Yuval Noah Harari, he explains it all (and many other things) really well. I found the book fascinating.

Heat death of the universe. I can't cope with the idea that one day nothing will exist.

That the universe is expanding, but not expanding into anything

That we live closer in time to T. rex than stegosaurus did

That one day the universe will have expanded so far that no stars will be visible from Earth

Sleeping. How we all trot off to bed and recharge and we just sort of zone out of life overnight.

And pets. That we have other species living with us in our homes as our best friends who love us.

@cookiecreampie

The afterlife and how I believe the universe is connected to it.

I'd love to hear more @cookiecreampie. I'm facinated by life after death and have loads of book on the subject. Would be interesting to hear your thoughts.

WiFi how can you send data through air?
