    The choices aren't: 'leave it alone' or 'real scientists can find it'. The choices are 'find it' or 'let it erode away'.

    Having just been reading the paper abstract (it's in pre-print at the moment, and I don't have the paper. Hmmm, "Alan Channing", there's a name that rings a bell.), where do you get that information from?

    Since specifically, the abstract refers to examining microscopic and mesoscopic (hand specimen size or smaller) fossils in chert deposits, it is not going to be particularly susceptible to "eroding to dust". That is genuinely an issue in, for example, the "badlands" of the Rockies foothills, but from the abstract, I would doubt it will be much of an issue for these fossils.

    Unless of course, you have a different source of information.

  6. You'll still be buying batteries and panels initially from someone. and there will be a (smaller) market for maintenance and/ or repair.

    Hay merchants used to provide many kilos of food every day to every propulsion source in the land. Then, as new transport methods developed, some morphed into selling coal (for railways), wheels (for wagons), or mineral oil (for internal combustion engines). And some people who remained selling hay for horses, went out of business.

    If Shell (to pick an example) chose to bring out a well packaged battery+15sq.m+controller package that would take someone 90% off the grid, then their marketing know-how and engineering expertise (don't forget - these companies have large engineering know-how. A sensor and metering package on a wellhead that ran off it's own solar panel + battery might save several thousand dollars/ year of costs, which would make a lot of sense to a company with 100,000 oil wells) could well make it a very attractive buy. Even more so compared to a foreign company like Texaco's package.

    OK, I've never (knowingly) seen a Blu-Ray or UHDVD drive or disc - there's no reason to, I see more movies in the movie house than I do at home - so I may have got this wrong, but doesn't the system depend on using a stamping machine to imprint many tiny physical pits into the material of a disc, then gluing a protective cover on one side of the (identical) stamping, a human-readable label on the other side, and throwing it into a (identical) case with another printed label.

    Where in the chain can they imprint a unique physical key onto the disc? Effectively you'd have to be burning a new copy of every disc. Unless there's some way of incorporating the necessary very fine pattern of pits in a different way into every disc at the stamping process.

    I would expect gravity-induced compression and expansion of the crust, mantle, and outer core to come into play when it comes to bleeding off energy.

    That is an effect. But rock is so much stiffer than water (and for that matter air) that the integral of force versus distance moved results in there being more work done by the hydrosphere (and atmosphere) than by the lithosphere. (The work also scales by mass moved as well as distance, so the contribution of the atmosphere is matched by the top 15m of the oceans, and the remaining approximately 4.985 km of the average ocean's depth is not matched by an atmospheric contribution.)

    Still, with the center of gravity of the earth-moon system being more than 4,000 km beneath the surface even today,

    1700km according to Wiki, and "a thousand miles" according to my memory. The point stands, though most of the effect is from movement rather than compression/ decompression. Typically on the continental crust the diurnal solid-body tide is on the order of a metre. People like LIGO and gravimetric surveys (e.g. for mineral prospecting) need to take this into account - it's a routine correction factor.

    If we accept the impact model, then we should expect that the chunks that ended up forming the moon were outside Roche's limit

    Roche's limit isn't a razor-edge dividing line, even in a system approaching equilibrium. The post-impact state of the Earth-Moon system as decidedly not near equilibrium, which is why modelling of the system has to be by running numerical integrations rather than attempting analytical solution. Well, so far anyway.

    What we do know (from the status of Pluto-Charon, Uranus, and Venus) with a fair degree of confidence is that large collisions were common in the late stages of the construction of the Solar system. (Unless you have a better way of accounting for the structure and orientation of these objects. Which would be a new piece of planetary science deserving of publication.)

    Also, since we don't know when we got the moon (we're not even sure how we got it), we can't just extrapolate backwards to a day of 6.5 hours.

    Correct answer (we can't simple extrapolate backwards) but for the wrong reasons (it's not uncertainty about the date of formation of the Moon that's the issue, it's the variable torque between the oceans and the seabed).

    I didn't bother to follow Ethan-ends-With-A-Whimper's links, but I welcom his movement from Forbes.com to the Torygraph and Nat.Geo (both Murdoch rags, IIRC), so one expects the former to get the science wrong, and the latter to over-simplify it.

    The actual science is that for some decades, geologists have been examining rock deposits which contain both daily and more-than-daily cycles of deposition. (For example, twice-daily cycles of tidal sand/ mud alternations and 21-day cycles that appear to represent the spring/ neap tidal cycle, in the same rock sequences.) There had been three reasonable quality measurements of this sort of data when I was a student (and wrote an essay on the topic) in the 1980s, and the number of measurements (in different formations at different eras) has increased since, with the noise reducing.

    The data is not consistent with a simple linear change, and therefore with any simple extrapolation.

    Further study of the interactions of the Moon-Earth system elucidates what is happening. The evolution of the Earth-Moon system is dominated by the drag between the oceans and the seabed. The rotation of the Earth drags the bulge of the ocean's high tides ahead of the line joining Earth-centre and Moon centre, so the bulge exerts a torque on the Moon, increasing it's orbital speed and therefore resulting in the Moon moving further away from the Earth. That much is well known and understood. What is less-well understood is that the drag between the seabed and the oceans is a very complex function of the shape of the seabed, the nature of the seabed (mud, boulders, seaweed, coral) and of course, the viscosity of the water. Just for entertainment, every such calculation for a deep ocena has to have a measure of the temperature profile between surface and seabed. The last time I did such a profile, the seabed was at 3.6 centigrade and the surface at nearly 30 centigrade ; the previous profile, the range was 9.6 to 15-20 centigrade (it varied with season, as did the isolation suits we were required to wear during transit). Even if you simplify the shape of the continents and the nature of the seabed, just the temperature variations is going to make it very hard to predict the efficiency of that torque transfer from the Earth's rotation to the Moon's orbit.

    And that is why a simple extrapolation doesn't work.

    We can be pretty sure that the Moon was closer to the Earth in the past, and there still is no better model for the formation of the Moon than the "Giant Impact" (not that that is without issues; but fewer issues than other models proposed to date). But we don't know exactly when, for example, the oceans formed (before 4300Myr ago, probably - but were they party evaporated by impacts later?).

    Well, it's 12 hours difference in 1600 years, and the substitution of mid-day for mid-night might possibly be slightly more noticeable than one midnight for another.

    There is no reason to expect that the orbital motion of a planet and it's rotational motion to be related in a simple ratio. (Except in the case of tidal locking, where the ratio is 1:1). So, unless you're going to go around adjusting rotation rates or orbits, then the slip between the two measures of time is just something you're going to have to deal with.
