Wouldn't that be a plot-line to a movie in a "Total Recall" theme. Exploring those still remaininguncollapsed lava-tube tunnels is going to be the ultimate cave exploration experience.
Maybe jets of ionised particles from the planet or other moons sandblast (or should that be ionblast it smooth). Just like those aerodynamic rock sculptures in the desert areas.
They then have a technology lead and control of the rare earth metals or whatever is required to make them. Things will go the same way as memory chips.
It's a facinating topic for someone like me who only got as far as high-school Geology. First of all, you have continental drift so that all the tectonic plates were one super-continent (Pangaea).
Then the moon was far closer to Earth that it is now - maybe four times as large. So tides would have been far higher, which would have meant more swamp land.
Less humans = more trees and forest
More trees would have meant more CO2. All the oil and coal is basically fossilised dinosaur food. So the climate is warmer and more humid than it is now.
I can only guess that if all the land was on one longitude line, the other side would have been ocean and hurricane.
I always wondered how insects in prehistoric times grew so large. As they have no lungs, they depend entirdly on Brownian motion for the exchange of O2 and CO2. During those times the percentage of oxygen in the air was even higher as well. Even fo the point that any dry wood would burst into flame, unless the air was extremely humid.
Look at the other research the Admiralty funded back then - timekeeping (pocket watches), astronomical calculatons (octants, sextants and easy to use calculation tables), tide calculstions, leading to signal processing and Fourier transforms, fluid dynamics and Navier Stokes equations.
Earth's magnetic field in space is really the average of all local magnetic fields in the planet. Imagine there were 20+ bar magnets, that sometimes pointed in the same direction and sometimes didn't. The magnetic field follows an inverse cubed law for strength.
My dad's workplace did some research into the accoustics of ocean eater. Ocean water has temperature, pressure, salinity gradients plus different types of wildlife at different latitudes and longitudes. All of these are going to allow creatures to triangulate their location.
It's like penguins that form huge colonies in the icy blizzard region. Navigating by visual landmarks is impossible in a blizzard, so they form a navigation system by constantly calling out.
I tried writing that comment using the Swype feature of my mobile phone. Typing sensible and coherent is virtually impossible when the buttons are half as wide as your fingers.
Must have been 15 years ago vut the UK had a school program which teached the concept of the number line using a series of fluorescent tubes hanging down from the studio ceiling. They counted numbers as tenty-one , tenty-two, tenty-three.
Perhaps the natives thought the number line was a parametric variable clamped to the range 0.0 to 1.0, or other values depending on the implementation of the number line.
Another was that long range radar systems would detect a large slow moving missile coming up over the horizon. Turned out to be the Moon - the radar signals were strong enough to reach the Moon and bounce back.
My undegraduate university was like that, being distributed across the city. Might not have been fun in the rain, but it did give us the chance to go outside and get some fresh air.
It's rather an academic debate as to whether Computer Science, Mathematics and Engineering should be in different departments or not. Usually they will be in the same faculty anyway (Arts vs. Engineering , and each professor will be responsible for their own research grant applications. But having separate departments is usually a measure of how many research groups they have.
That isn't too bad. The Egyptian pyramids took the lifetime of a Pharoah each. Cathedrals in Europe took 300 years to complete. As for some government projects. The Great Wall of China (technically many smaller projects) continued on for 2000 years.
Insightful point. To process all that metal, we would need some way of heating and melting it into containers, then some way of fabricating rocket and space station parts from that metal. If there is water, that could be split into hydrogen and oxygen.
Sounds like the perfect way to build a ring world. Send out one mining ship to the asteroid belt. Mining ship fabricates and builds more mining ships. This continues until there are mining ships all along the asteroid belt. The mining ships then proceed to start forming segments of the ringworld which are then sent on a trajectory to intersect with the other ringworld parts.
Land based communications rely on ancient copper wires installed 50 to 100 years ago. The resistance/cspacitance values don't match the requirements for high speed broadband. The only real solution is fibre optic cabling, and a wifi router at the end for mobile devices.
But you can cut the middle-man out by just having wireless internet.
Same in Norway. Some apartments don't even have sockets for landlines. There were junction boxes with 4-way cable but the face plate was blank. All around the apartment were Data/TV/Satellite coaxial connectors. Skype over mobile offers better line quality than regular mobike phone (no echoes).
Whenever something happens, the usual catch phrase is "We will do a review and look where we can tighten up security". Their fear is looking like idiots if they didn't improve security the first time and the same event happened again.
Why do you think there are CCTV cameras on every corner in the UK? That was the first response. Then they made the financial area of Londin a car free zone. Something that the Green parties had dreamed of doing but were ignored. Then we have the logging of every telephone call, SMS message, Email and visit to a website. Finally, we have the X-raying of everything including shoes.
Theres an application for the Ssmsung galaxy that measures pulse speed using the flash light and the camera. But measuring blood pressure still requires an inflatable cuff.

There are audio recordings of the rapid changes in the Earth's magnetic field at points on the ground.

You missed out double-decker bus - that will confuse Londoners if you don't mention this .

Since the atmosphere is thinner than Earth's, any meteorite coming in at 25,000 km/hour isn't going to be slowed down or burnt up.
It's going to be more like shrapnel than sprinkle.
Yes, typo. Should be £10 per month. Mainly due to the demand from the student market.
Depends on your country. In UK cities, you could get ADSL for as little as £10 / year, or go for 100 megabit broadband for £50/ year.
In the cooperative housing I am in, wired internet is included in the rent, along with the central heating.
