Last week, I got seriously obsessed with what, at first glance, looks like a really daft question:

What does the Internet actually *look* like?

All the ways to answer this are fascinating and full of surprises. Here are some in a thread:

1/
Here is the simplest, most straightforward and wrongest answer.

It looks like the box in the corner of your room that you sit in front of every day, "enjoying" its contents.

Devoid of context, that's what my senses tell me. But obviously this is absurd. Let's move on.

2/
If "the Internet" is the signal, all that data flying around, then in a sense it looks like this.

99%+ all international data races along sea floors at around 16 mill. times the force of a home Internet connection, through cables roughly the width of a can of Coke.

3/
Incredibly, the first colossal undersea cable was laid back in 1858, when two steam-powered (!) battleships met mid-Atlantic to connect together two pieces of a telegraph cable running for over *2,500 miles*.

Alas, it only worked for 3 weeks: spectrum.ieee.org/the-first-tran…

4/
Or maybe the Internet is where data *stops* moving, in the data centres and other machine-holding architecture.

Photographer Dave Greer got curious about this, with oddly beautiful results (in a Simon Stålenhag sort of way): qz.com/770849/these-b…

5/
Or maybe our best way to see "the Internet" is indirectly, to trace its passing - like this mesmerising datavis of geotagged tweets using the hashtag #sunrise one day in 2014, showing a spluttering blaze of yellow marking dawn:

cartodb.s3.amazonaws.com/static_vizz/su…

6/
Or this from opte.org, looking like a colourful explosion of dandelion clocks:



It shows the Internet knitting itself together, network by network. It looks *alive*.

(This may creep you out a bit.)

7/
Or this, mapping tweets from mobile phones:

labs.mapbox.com/labs/twitter-g…

(Red means iPhone. As a European Android-user, I had *no idea what a minority I was in. At least on Twitter, anyway. Eeesh.)

8/
This zoomable "star map" of websites from 2012 is engrossing and more than a bit bonkers in scale:

internet-map.net

(I can find my old blog on it. It's tiny but it's there. Had a website for more than a decade? Go searching. I bet you'll find it.)

9/
But maybe the only maps that fit here are abstract, subjective and virtual. Maybe you have to be *inside* to map it properly.

Kevin Kelly's Internet Mapping Project asked people to draw what they thought the Internet looked & felt like: kk.org/ct2/the-intern…

10/
"The internet is intangible, like spirits and angels. The web is an immense ghost land of disembodied places....Yet everyday we navigate through this ethereal realm for hours on end and return alive. We must have some map in our head." - Kevin Kelly (brainpickings.org/2009/06/08/int…)

I'm writing more about all this soon, first for paying subscribers & later for everyone, in my @SubstackInc newsletter, Everything Is Amazing:

Sign up if you're curious.

But before I end this thread, my current fave map of them all...

12/
After a year of work, designer Martin Vargic has completed a modern-day Mappa Mundi of the online world:

The detail here is just *staggering*. The research alone must have been...I just can't.

Just barmy.

And if all that has left you feeling a overwhelmed and a bit lost, don't worry! Here's the end of the Internet, so you at least know where one of the edges or corners is:

This is Sandy Island, in Australia's Coral Sea:
- 15 miles long, 3 wide
- First recorded in 1774
- Not actually there.

It's the world's most recently undiscovered island, after 2 previous attempts to undiscover it failed. (What a sentence!)

Here's the story...

1/ Image
In April 2000, radio enthusiasts on a 'DX-pedition' (radio-mapping a remote place - “DX” is telegraphic jargon for "distant") sailed in search of Sandy Island.

Here's a modern Landsat pic of what they found. If you *really* squint...

Nah. No point! There's nothing there.

2/ Image
Here's a British admiralty chart from 1908, showing Sandy Island upper middle-left - apparently via data from a French whaling ship 'Velocity', which claimed it charted the island in 1876.

Whoops! Well, these things happen.

But satellite photos should settle it, right?

I thought I knew the story of the "lost world" off the east coast of Britain, inhabited by Mesolithic people until rising sea waters engulfed it around 8,000 years ago...

But I didn't know about the *tsunami*.

Holy hell.

What follows is my imperfect grasp of things.

Imperfect because I'm just an enthusiast who likes science - and also imperfect because, excitingly, the work is still going on, as part of one of the greatest prehistoric archaeological investigations in history.

2/ Image
One September night in 1931, the British vessel Colinda hauled up its nets 25 miles off the Norfolk coast - and found something beautiful & deadly.

Embedded in a lump of peat was this 8.5 inch prehistoric harpoon, carved from bone or antler...

When I wrote about the Zanclean Megaflood filling the Mediterranean in 12-18 months (!) it was wistfully.

I'm English. Lovely place, England! But - Big Geological Drama? Not round 'ere, sadly.

Imagine my delight at what geophysicists have found in the English Channel!

1/ Image
500,000 years ago, Britain was still part of the continental European landmass via a land-bridge - the Weald-Artois anticline, formed as rock buckled across Europe as the African plate ground northwards over tens of millions of years.

(This also made the Alps!)

But...

2/ Image
...surely it was nibbled away gradually, as water crept in over thousands of years?

That was the assumption until recently.

But in 2015, bathymetric data collected by marine geophysicists at Imperial College showed 36 underwater “islands” suggesting a different story!

I recently learned something amazing about the Arctic - & my tiny mind is blown.

In my ignorance, I've always believed it's featureless & barren. But now I've learned what's underneath it - & if THAT was on dry land, it'd be a wonder of the modern world.

Buckle up!

This is Mikhail Lomonosov (1711-1765): Russian polymath, scientist, writer - a lesser-known Isaac Newton.

He discovered the law of conservation of mass in chemical reactions, first saw Venus has an atmosphere, founded some of the key principles of modern geology...

2/ Image
...and a town, a lunar crater, a *Martian* crater, a satellite, a porcelain factory (!) and an asteroid have all been named after him.

And at some point, as legend has it, he predicted there was something MASSIVE under the Arctic ice.

OK, this is nuts.

In Sept 2023, geophysicists over the world started monitoring an odd signal coming from the ground under them.

It was recorded in the Arctic, then Antarctica - then everywhere, every 90 seconds, regular as a metronome - for NINE DAYS.

What the HELL?

1/ Image
In seismology, this is a USO: an Unidentified Seismic Object.

Perhaps if this discovery had leaked into mainstream news as quickly as potential alien biosignatures tend to do, we’d currently be seeing a big comeback for the HOLLOW EARTH ‘theory’.

Thankfully not the case!

2/ Image
Instead, in the best collaborative tradition of modern science, researchers across the globe - 68 scientists from 40 institutions in 15 countries - joined forces to track down the signal’s source.

What they found was astonishing!

(Yes yes, I'm getting there.)

A while back, I learned something mindblowing about the geological history of the Mediterranean Sea, and I just can't get it out of my head.

Now I'm going to make it *your* problem too. Sorry.

Hang onto your hat. This gets wild.

This is the Strait of Gibraltar, where Europe and Africa reach out to almost touch each other.

At this point there's only 13km/ 8 miles between them - & it's where the Med feeds into the Atlantic.

Imagine if something absurdly violent happened & it closed up?

2/ Image
No need to imagine - because it actually did.

It's called the Messinian Salinity Crisis, & it happened around 5-6 million years ago:

After a presumably colossal tectonic shift, the Pillars of Hercules closed (or more correctly were bridged)...
