Sharks are electrosensitive, They use it to detect prey So impulses from undersea cables are a draw for them

Pedant alert. Undersea telecoms cables don’t conduct electricity… they’re fibre optic - they transmit light.

@@AlbertaGeek the cables carry electricity also as the fibre optics need repeaters, it's not a single 8000km long cable - there's multiple stretches that get spliced together on the cable laying boat.

In the comments to the original Map Men video, it was revealed that the globes falling off the wall was purely accidental, but they just rolled with it.

Your reactions are consistently a pleasure to watch!

Communication satellites are at geo stationary orbits (the new ones like starlink are in low earth orbit, yes, but that's new). That is far out, so they add quite some latency and their bandwidth is also kinda limited, since only so much fits on one frequency band. Signals over fiber cables travel much shorter distances and one cable can be next to another. No bandwidth limit here. So yes, the internet is mainly via cables today.

You can literally react to anything and I’ll just sit here in admiration ❤

I watched an hour long documentary on the attempts laying the cables between the uk and us it definitely wasnt boring

Yeah , saw that, The repairing Breaks was impressive

The fourth cable attempt was started from both ends and the idea was to make a join mid -Atlantic. However, it was found that British and US cable braiding were “handed” in different directions and incompatible for a simple connection. So, One ship had to hold both ends for some weeks, whist the other returned to base to have a special adapter made-up.

Absolutely LOVING you reacting to Map Men!

2:31 Telegraph: from the Greek Tele (=distant) Graphos (=writing). See also telephone (distant sound), telepathy (distant thought), telekinesis (distant movement) and telemarketing (take a wild guess). This posed a problem for the inventors of television. The Greek for distant seeing was Tele + Skopos. Unfortunately, a chap called Galileo had already nicked this for his telescope. So a new word was coined that was half Greek (Tele) and half Latin (Videre - to see).

Originally the cables were laid under the oceans from Porthcurno, Cornwall, England, all across the globe to connect the British Empire. It is all still at Porthcurno, and some cables can still be seen on the sandy beach. What they never mentioned is the fact that all over Cornwall there are secret stations which are used by the UK Military to connect to US Military, and others. If you check on KZread there are a few very interesting videos showing you how to find them, just by looking for the signs down country lanes. I don't mean actual signs but markings in the roads or on the buildings. Its all mind blowing stuff!

There are 2 that terminate here in North West England (Southport), EXA North and South, so called because one skirts around the North of Ireland and the other around the South. I can see the terminal hub building from my front window.

OMG the router bit was great, love your reactions to these guys

You need to read some Terry Pratchett, not only are they highly entertaining books but Sir Terry had a way of educating you on the sly. I have been nudged into many historical and geographical wormholes because of The Discworld and even had to learn a bit of German for Unseen Academicals (as well as a buttload of history about football). RIP Sir Terry xxx Forgot to say that this comment was inspired by The Clacks system on the Disc.

I really like that he doesn't always either take things at face value, or just think they are jokes: he's very willing to fact-check now and then. This is especially important for Map Men videos, as sometimes it's genuinely difficult to tell if they are joking or not. 🤪

If you want to know one of the most economically expensive sharks, find the Cookiecutter Shark.... it's an opportunist ambush scavenger, the usual prey is large soft skin aquatic animals (eg. Whales, other sharks, large fish, giant squids)... however the sonar domes on Submarines are an easy mistake, and the damage ends in the millions of dollars.

Yeah the first transatlantic cable stretched from Valentia Island in Kerry, Ireland to Newfoundland. Valentia is about as far West as you can possible go in Ireland. My father is from there and it’s one of the reasons that the entire island has been considered for UNESCO heritage site status (along with the tetrapod tracks along one of the cliffs). All over a very cool place to visit

8:35 That cable that goes from America to America isn't as illogical as it seems. Apparently, it connects to a number of oil-drilling platforms en route.

LOL why am I not surprised you are reacting to yet another Jay Foreman (with Mark C-J) once you've seen one, you are compled to watch them all.

I know this if off topic, but have you ever thought about making an ASMR video? Your voice is so relaxing, simply terrific 😌

I learned about the first Trans Atlantic Cable laying, when i bought a Book about the ''GREAT EASTERN'' the worlds largest iron ship, made by Britains greatest Engineer ,Isambard Kingdom Brunel. Having ended it's days as a Passenger liner. The ship was kitted out with massive Drums of Telegraph wire, linking first, Eireland accross to Newfoundland, and a second cable to America.

There is a road (on a hill) in south east London, named Telegraph Hill. I've always wondered why... Now after watching your reaction to the Map Men's video on this subject, I've been reminded of Telegraph Hill and now want to "Google" it and find out the reason for that name, except, maybe that question has been partially answered !! Thankyou JJLA for helping to prompt me to finally solve my "age-old" question. 😊🧡🖖

It's delightful you have to look up everything to determine whether it's fact or sarcasm. TBH, these boys are right on the edge of British sarcasm. You'll be trilingual in American English, English and sarcasm when you've finished.

Sharks like to bite cables and often leave their teeth in the cable sheaths.

3:16 Yeah, bribery. Towers are far apart, so that you can't see A from C if your towers are A, B and C. That makes the most distance, which allows to use less workers. However, said workers are indeed easily able to, say, send a different signal down the line if asked "politely" enough. Making the message about the royal wedding completely different for that one unstable part of the country that was waiting for a good reason to revolt.

Satellites interduce delays as Geosynchronous satellites have a delays of approximately 0.25 of a second to reach and return from the satellite

,love your vids, I actually put this fibre in over the UK.ironic bit is when in Cornwall we put fibre to the building where the original cable for the telegraphs uk-usa We upgraded the original,also to Henry 8th's pad Hampton Palace,his 'drive' used to be on our money 😂

Definitely watch the episode they do on Marine Chronometers.

Sharks can perceive electrical fields in order to find prey. While these cables transfer the data via optical fiber, the signal needs to be boosted several times in the ocean. That signal boosting is of course powered via electricity, so there *is* electricity in those cables, too. Sharks detect that and confuse it for prey.

I knew about the towers from the count of monty cristo 😅

There’s a great Fry and Laurie sketch about the English language

Hey @JJ. I think you may find this video interesting, The Secrets of Cornwall prt 1, by Mark Thomas. I've watched it a few times as there's so much to take in also I live in Cornwall, I was aware of some of it, but lots I didn't know about. Hope you watch it.

All the internet is, is our old Telephone Copper cable system.. its only just slowly going to optic fibre to people's houses but all the cables are the old phone lines from forever ago

Then after privatisation most Tele communication companies leased/rented the use of these extraordinarily large powerful data transmitters. But like having a storage building and renting out a unit. All sorts o independent companies set up but most early companies crashed. But big players cleaned up. Then new cable players entered ( patents running out/ new tech) . So solar storms on satellites not so 😮😮😮 as underwater cables in vaseline seem protected. 😅

I'm not sure the illustration at 3:23 is exactly how electricity works. Everyone knows electrons only flow downhill.
