Pangea

How balanced is the earth as it spins? At one time all the land mass was concentrated in a super continent known as Pangea. If you re-created this in a spinning top it would surely develop a severe wobble.

Everything's fine while the oceans don't evaporate, but if they do then I'm sure we can re-sequence the E-W traffic lights to counter against any perturbances.

I saw some earth moving trucks working along the A14, now either they are improving the road, or do you think it is a cunning plan to shift the earth about a bit to correct the wobble?

Anyone else seen any the world over?, it may be not just a cunning plan, but a global cunning plan...

Actually a severe wobble is self correcting as the lump bits fly off and create moons

It's all in the plan of creation

just think about, it helps you go to sleep

There are recently discovered cities off the coast of Cuba and India that would suggest that the continents shorelines weren't always as they now are. Magnetic Pole reversal, tilt changing over time, who knows. Probably the mice or Slartibartfast.

late design changes by the mice and Slarti was not happy about it maybe?

Would you believe that there are people who have never even heard of 'The Hitchhiker's Guide to the Galaxy', let alone Slartibartfast?

Somewhere on my Kindle I have 'The Hitchhiker's Guide to the Galaxy: The Trilogy of Five'. For some I have never got beyond Part III.

Never hurts to remember that:

1) the variations of the Earth's surface have been likened, proportionally, to the dimples on a basketball. Mountains and continents look huge to us - on the scale of the whole Earth they are as flat as flat. Literally "rounding errors."

2) the crustal plates float on top of the mantle and core. Crustal rocks and water are - relatively speaking - featherweight material. The crust masses about 2.5 x 10^19, the whole planet masses 5.9 x 10^24 (240,000 times as much).

Spin a basketball (625g). Now, tape a large ant (.005g) on one side of the basketball and spin it again. See any extra wobble?

Edit: be sure to spin that basketball at the same angular velocity of the Earth - One revolution per 24 hours.

The outward "g" force or centripetal force or outwards acceleration at the Earth's equator due to the spin is 8.54 x 10^-4 m/s^2. Less at higher latitudes.

The coastline is still changing. Half of Walton on the Naze went to sea some years ago.

I've often wondered about this too. I read somewhere that The Three Gorges Dam in China has had a minor effect on the Earth's axial inclination, therefore it follows that movement of crustal rocks, which are 2.5-3.5 times the mass of water, should do the same. There have been 2 or 3 'supercontinents' before Pangea, Rodinia being the one previous to it, and I think there were 2 more. Interesting stuff.

Joke all you like, but we conspiracy theorists aren't going to be hoodwinked and I've got photographic proof that 'they" are trying to alter things!




"They" are trying to tell us that it's the start of a mega-expensive sand shifting process to reshape our bit of the coast ... as if!!

Lyneham Lad, maybe you are just lacking a bit of reason???
