Days have become shorter due to earthquake!

[lazyitus]

The earths axis has moved because of the chille earthquake!

Blimey !

[tegwin]

research scientist at Nasa's Jet Propulsion Laboratory in California, calculated how much the axis may have changed


Total and utter non story!

Great, that means I have to spend 6 micro seconds less at work per day

If the planet's axis did shift by 8cm during the quake, days would have shortened by 1.26 microseconds, Mr Gross calculated.

A microsecond is one-millionth of a second.

Indeed.

If the dodgy bastids think their getting away with the MMupGW scam that easily they have another think coming.

I think we must resign ourselves to the harsh reality that we now face due to this disaster; the only way to ensure it doesn’t happen again is to impose a 20% earthquake tax on everything that can be linked to earthquakes, seismic activity or Chilli

Why did they have to call it 'Stag'?

I'm not sure how the axis or day length would have changed? Anyone fancy explaining? It would be like standing on a park roundabout, and getting a big weight, and moving it back and forward. Surely all the forces would equate?

skater / dancer analogy - they speed up rotation by bringing their arms (mass) towards the centre of rotation.

Ah.. I wasn't thinking on inwards, just crusties moving about.. Cheers.

Don't worry, another earthquake somewhere else will restore the old rotational speed.

Or speed us up more! What if we all fly off into space?

The length of an Earth day is increasing all the time due to tidal interaction which also causes the Moon to move further away over time at a rate of about 38mm/y, so this theoretical possibility of a very slightly shorter day (a microsecond ish) would soon be offset. The tidal increase in day length is about 2ms/100y so with 2 milliseconds in a century corresponding to 0.05 microseconds per day it will be just over 25 days from the date of the quake before this possible change is offset by the Moon-Earth interaction.

All figures need checking due to the possibility of memory problems from a need for sleep after being woken up only a few minutes ago by an alarm clock that may now be wrongly set due to the quake

However the above situation is complicated as mentioned in earlier posts due to the fact that there are changes in the Earth's polar diameter and equatorial diameter from effects such as post-glacial rebound so all in all the position can be summed up as - buy a clock linked to the radio time signal that updates automatically and forget the quake.

I'll sleep soundly anyway now the Daily Mail is on the case, but as I'm quakingly tired I didn't check if they mentioned any NASA calculation arising from the 22 May 1960 Chilean 'Valdivia' (misnomer) monster shake that measured a record 9.5 on the Richter scale.

That's all very well, TB, but answer me this...



How do we know that time is right, now that the earth is all screwed up time wise?

[turbobloke]

So, before heading out I should pause for thought: depending on what 'real' time is taken to be, I need either to add or subtract 1.26 microseconds from my daily rate.....

Will it affect "East Enders",..............

I do hope so.

[Dave^]

So is this the real cause of the recent ApocalyPS3?

(The PS3 issue from 1st March?)

maybe we should all use microsoft time, you know when your downloading something and it states 5 minutes remaining then it go's upto 6 then 7 then down to 4 then 1 then back to 5. that would fix it

Or a bus time table.
