I mentioned this on another thread, but how the Internet works.
How my phone can almost instantly find then access a web page half way around the world. People talk about servers but there must be millions of them, so how does my phone know which one the information is on?? And how it does it so quickly.
I shall live in bliss though and not worry too much

The Pyramids of Egypt. Absolutely blow my mind. We couldn’t recreate those with 100 massive cranes and thousands of workers. Yet they did it way back then with ropes and animal power!
Well, quite recently they've been able to work out that there was probably a part of the Nile that flowed near by, which would explain how they may have transported things.But I've never seen the Pyramids and I didn't quite understand just how big they were until I watched a YT video of some guy visiting them. And some of the shots from down near the base do a really good job of giving you the sense of scale. They're absolutely huge! Very impressive in terms of size and the fact they're still here and most of the damage has been people removing stone from them.

As an extension to that.... YouTube. Think of all the people constantly uploading videos (and in 4k to boot). How the hell do they keep on top of all the storage for this? They must cull channels and videos that are "inactive" but presumably if there is an "inactive" channel, but people still watch the videos it stays?How my phone can almost instantly find then access a web page half way around the world.

Same goes for blind from birth I suppose. Without any base line, what do they see, if anything. is it all black? all white? all brown? would they be able to explain it in terms we could understand? what does absolutely nothing look like?
I spoke ot someone who was blind from birth and they explained they had no input whatsoever, it was hard to get my head round it until they suggested I tried to move a chair with my telekinesis ability..... when I said I couldn't do that as it didn't exist they said that was exactly what sight was like for them.There's an interesting guy on YouTube, blind from birth, that tries to explain what he does not see.

Good timing this. I’ve never really thought about space but I watched a documentary the other night about the creation and launch of the James Webb telescope, and the distances they started talking about (and the amount of time images take to travel) were absolutely mind blowing. Ie. It took 30 days to get to the position it’s in, a distance of a million miles from earth. Then it takes an image of something which is so far away it would take a 13.6 billion years for the image to travel from the item back to the telescope. So even if we see a distant ‘planet’ we are only seeing what it looked like 13 billion years ago, as I said, mind blowing.
The light that's been travelling 13.6 billion years is the limit of the 'observable universe'. Anything further away hasn't reached us yet. But there is possibly infinitely more beyond that distance.And because the universe is expanding it means the things we are seeing from 13.6 billion years away are now much much further away than they were.
With interesting Races shown. There was also the ship that hit warp 10 that Tom Paris in voyager piloted
And turned him weird.. that would win any race because, well, it will already be there. Fantasy I know but does try to explain the ships speed compared to light which is really slow in comparison

If those ships did exist, how would they travel that fast without smashing into something? (fantasy ships I know but just trying to understand if it would ever be possible to reach these galaxies far, far away……)

At the time of the Roman Empire, world population was estimated to be about 300 million.
By 1650 world population was only around 500 million.
350 years later in 1800 it hit 1 billion.
150 years later in 1950 it hit 2.5 billion.
70 years later its 8 billion.
I can't get my head round how empty everywhere must have felt, but I guess it didn't to those at the time.
In a similar vein, I bumped into a couple in our road today who lived here in 1980 and were having a little trip down memory lane. They bought the house in 1974 for £11K and sold it in 1980 for £30K. This house is worth £600K today.By 1650 world population was only around 500 million.
350 years later in 1800 it hit 1 billion.
150 years later in 1950 it hit 2.5 billion.
70 years later its 8 billion.
I can't get my head round how empty everywhere must have felt, but I guess it didn't to those at the time.
They then bought a house for £52K 2 roads away which 44 years later is now worth £1.6 million.
That extra £22K they spent moving house is the equivalent of £1 million 44 years later.
I would have to effectively work my whole life to pay for something that cost them £22K back in 1980.

I lived in a village 6 miles from town and it was a straight run. Now there are about 10 sets of traffic lights and 2 roundabouts.
Looking for a house in the late 90's when planning to get married and we spot my Dads old 4 bed house on the market for £112k. Crazy thing was the interior had never been updated and it still had the avocado bathroom with psychedelic purple glitter wall tiles. My Dad bought it in the early 70's for £3k.

Even now the world as a whole is still pretty empty you look at some of the continents and nobody lives in huge areas of them. I’ve been to Australia a couple of times I once took a train from Melbourne to Sydney absolutely nothing for hours and hours and hours. By 1650 world population was only around 500 million.
150 years later in 1800 it hit 1 billion.

Einstein's light on a train paradox.
A fast train passes a platform and a light switches on in the centre of a carriage. An observer in the carriage sees the light hit both ends simultaneously. An observer on the platform sees the light hit the rear of the carriage before hitting the front

Lots.
Who decided on the alphabet?
Who decided 2+2=4 (same for all other number combinations)
The universe in general, but party expansion, what is it expanding into? what is at the end? There has to be an end, and what is beyond that end?
Why we spend 5 days a week working to live for 2?
Why my brain has an incredible ability to fk me over?
Women?
Etc

I haven't looked it up but think it's comparable in size to the Milky Way so more than 150 light years across.It contains a trillion stars, and it takes light 150 years to get from one side of it to the other.

The 5:2 thing has annoyed me since I started work it’s absolutely ridiculous.

Expanding into what though? I’ve always wondered.And because the universe is expanding it means the things we are seeing from 13.6 billion years away are now much much further away than they were.
Also with regards to the big bang theory,I’ve always wondered how something was there to start with in order to kick start it all,so surely there has always been something about and therefore there can’t be a beginning of time as my small brain can understand,which means there’s always been an existence of sorts.Always.
