Earth's Rotation is Slowing

Hi guys !
I was in one of those science moods tonight and it got me thinkin.

Its comon (i think) knowledge that the Earth's rotation is slowing down.
They (the smart guys) say that in the next 150 million years we will have a day that lasts 25 hours.
But in 150 million years, the way evolution has been in the past, there will be a new species dominating the planet, providing history repeats its self.

But what really got me thinking was they say in the next 20000 years, there will be one extra second in each hour, which would surely impact humans to some degree, we should still be here in that time id think.

So what do you think they are gonna do about that?

Do you think they will revise the clocks to show 61 seconds?
Do you think they will actually lengthen the second to adjust for this?
Do you think they will leave all as it is and give us like a leap hour ever so often or somthing to that effect?


The interesting thing about lengthening the seconds, while it seems like it would be the easiest way to deal with this is that would alter all our standards for frequencys and rates. Think hertz and even motor oil is measured by the time it takes to flow through a certain sized hole.


Im interested in your guy's thoughts

So if Earth's circumference increases with 100km, do you increase the km value to 1002.5m just so the circumference will stay the same?

Anyway, 20.000 years from now, our robot overlords won't give a shit if it's day or night.

The lizard people who dominate the food chain's top tier will not use primitive elect - mechanical devices for any purpose.

By then the lizard people will have all been eaten by the Morlocks and everyone knows they live underground.

The zombie's from outer space will have already taken over. Zombies aren't too concerned about time.

The Chinese won't mind then... LOL

well, we need new style of watches and movement then.

This makes absolutely no sense. There can never be an extra second in an hour. An hour is an arbitrary length of time (made up by man) and defined as 60 seconds. Accordingly, by it's very definition it can never be 61 seconds. I hope this was a joke

The article says that they may redefine how long a second is, which of course would change the number of seconds in an hr., unless of course you redefine the hour. That's a completely self serving statement. As I mentioned above, seconds, hrs minutes are all defined by man. They cannot change somehow unless we change them. It certainly isn't astonishing to anybody that something changes if you change it.

As to the slowing of the earth's rotation, very factual and interesting article. Thanks for sharing.

This thread is much too heady for me to respond to, other than to say that like the earth, I too am slowing down.

An extra hour [25 hr/day] would give me an extra hour to nap. ff2bed: .....To take a few more puffs. :matty:.....A few more cups. ............. Heck, even another hour with your better half ! ............. I think it's a good thing !!

No it wouldnt be astonishing, but IF they did change how long the second was, to keep our regular 24hour time standard, think of all the ramifications that would have.
In the US our electonics all operate at 60 HZ (cycles per second) so it would now be at like 63 HZ, or it wouldnt operate properly, all technical documents would have to be updated.
Quarts ocillators would all have to be retuned.
Hell, even the way we measure horsepower would be off.(one Hp is moving 33000 pounds one foot in one minute or moving one pound 33000 ft in one minute.)
Then our electrical watts measurment would be off too as 720 watts = 1 Hp

Keeping all this in mind ,i dont think they will redifne the second

i think we will end up with some sort of leap second ever now and then, possibly around day light savings time adjustment or something to that effect

And cybee, the cool thing is even though you are slowing down, with the Earth slowing down too, it would make it seem as you are actually going FASTER ! What used to take you an hour to do would then take you 58.374 minutes !

SCORE !

My head hurts, F this, lol.

I'll be dead from either Ebola or ISIL...so f*** it. Who cares. Cool college chat though, sorta

Dude, mellow the attitude just a tad. Who says we (mankind) can't change the definition? Physics is pulled apart and rewritten every couple of generations so I don't think declaring an hour to be 61 seconds is that big a deal, jeeeze . . .

At any rate IMO the answer would be to lengthen the second rather than add any to a minute.

I think about a dozen quantum drives based on dilithium crystal technology placed strategically around the equator and attached to the neural net cloud computer system name HAL could straighten this out in no time. A couple of little pulse bumps every 1000 years or so could keep us in sync.

Human existance is only 2-3 generations from the great filter. Afterwards Earth will heal itself and evoloution can start over.
