"Laser Train" is a perfect name for a 70's hair band, a dance club, fighter pilot handle, even a dog name. It's an all-purpose perfect name!

Duh, this isn't new, it's the mechanics of how the Earth has fluctuations of the magnetic fields including full magnetic poll reversals.

"We found that, compared with the mantle, the inner core was rotating more quickly in the 1970s and 1990s, but slowed down in the 80s. The most dramatic acceleration has possibly occurred in the last few years, although further tests are needed to confirm that observation."

The inner core doesn't generate the magnetic field.

Atomic clocks have always been wrong.  Just not very much.

Clocks have been even wronger for centuries and we did alright.

Recent results suggest the possibility that decay rates might have a weak dependence on environmental factors. It has been suggested that measurements of decay rates of silicon-32, manganese-54, and radium-226 exhibit small seasonal variations (of the order of 0.1%),[15][16][17] while the decay of Radon-222 exhibit large 4% peak-to-peak seasonal variations,[18] proposed to be related to either solar flare activity or distance from the Sun. However, such measurements are highly susceptible to systematic errors, and a subsequent paper[19] has found no evidence for such correlations in seven other isotopes (22Na, 44Ti, 108Ag, 121Sn, 133Ba, 241Am, 238Pu), and sets upper limits on the size of any such effects.

so not so much

I hope they can explain where all that extra work comes from to accelerate such a massive object. That had to come up during review. But of course I'm no geoscientist.

Yeah, pretty much.

Q: [analyzing the cause for the Bre'el IV moon's trajectory] This is obviously the result of a large celestial object passing through at near right angles to the plane of the star system. Probably a black hole.

Lt. Cmdr. Data: Can you recommend a way to counter the effect?

Q: Simple. Change the gravitational constant of the universe.

Atomic clocks have precisely nothing to do with radioactive decay.

Yep, it's all about exciting electrons and the rate at which they release that extra energy as photons and such.

Though that is variable depending on velocity, such that a clock on a top shelf will run ever so infinitesimally but still measurably slower than one on the bottom, as per relativity.

And then there's the fact that no one uses a single atomic clock to tell time, but instead the average of hundreds of them, which cancels out any issues with variability.

This sentence should not have been written.  Atomic clocks -- that is, cesium-beam frequency references, CBFRs -- do NOT rely upon radioactive decay.  To perhaps oversimplify, a CBFR has an oscillator whose frequency is adjusted by feedback so as to obtain the maximum microwave frequency oscillations from cesium atoms.  As the oscillator naturally changes frequencies, the amplitude of cesium atoms resonating to the frequency falls, which in turn adjusts the oscillator frequency, again aiming for the maximum output.   This keeps a REMARKABLY stable frequency going, which is then counted for a time reference.

Besides that glaring error, radioactive decay is a probability function -- it is, averaged, constant.  The larger the sample size, the better the average will be.

And, finally, ALL clocks are "wrong" in that there is no absolute.  However, the error in a CBFR is small enough that it takes centuries to accumulate a second of error.  That's close enough for most purposes -- and that's just an 'everyday' CBFR.   The clocks used as primary frequency references are even better.

Sorry, if the k changes then the radioactive decay rate increases and your probability function becomes slow.
They've proven that k isn't a constant, just a highly probable number based on the relativity it is within,

Agreed.  That movie knew it was going to suck, and everyone involved knew how bad it was.  So they did the only thing they could: went so over the top it became awesome.  Sure the science of the movie is pants on head retarded, but I don't care, it's fun.  And some movies are supposed to be fun.

It felt like a waste.  I walked into the theatre totally expecting a silly, B-rate comedy that might be trying too hard to be serious, but then where the hell did all these really good acting performances come from?  I found myself wishing the script was a million times better because the actors were punching so far above their weight.  There are times when you want a movie to be all bad, and The Core was one of them.  That movie is strange in that it really needed some hilariously terrible actors to make it more enjoyable.

It's funny but I was pondering why that movie was so terribad and I think you're right.  It needed more ham, if it'd of had that then it'd of been quite the enjoyable little B-movie.
