Math- Earth slowing down!!!

[worship4ever]

Presently, the earth's rotation is slowing down 0.005 seconds per year per year. The actual rate of 0.005 seconds per year per year yields, if rolled back 4.6 billion years, a 14-hour day.
Let's do the calculation for 370 million years ago:

((0.005 sec/yr) x (370 million yr))/Year = (1,850,000 sec)/Year
= (21.4 days)/Year

Thus, at 370 million years ago, the earth had 21.4 extra days per year.

The total days then per year were: (365.25 + 21.4)days/Year = 386.65 days/Year.

(8766 hrs/Year)/(386.65 days/Year) = 22.7 hrs/day

If you do the same calculations for 4.6 billion years ago, you'll get the 14 hrs/day given by Drs. Thwaites and Awbrey. Thus, there is no problem here for mainstream science. Indeed, the present rate may be too high:

The correct present rate of slowing of the earth's rotation is excessively high, because the present rate of spin is in a resonance mode with the back-and-forth

Motion of the oceans' waters in the ocean basins. In past ages when the rotation rate was faster, the resonance was much less or nonexistent, resulting in a much more gradual slowing of the rotation rate. The most recent calculations indicate that the earth could be 4 to 5 billion years old and not have been spinning excessively fast or requiring the moon to be any closer to the earth than 225,000 kilometers (140,000 miles).

The earth even exsisting with such days would cause some freakig occurances. Freaking occurances that seem weird to us in the bible, seem a bit possible.

Like what?

(Never mind that the Bible only goes back about 6 millenia or so... so the Earth would not have been rotating much slower.)

Also, you need to look at the rate that the moon is moving away from the earth. The solar system tends to synchronize itself. So one is transfer to the other. The moon is vital to holding the earth in the 23 degree angle, and that is what causes our seasons.

If the earth was spinning at the same rate the rest of the universe is moving, then there would be no light on the earth.

 

[Jet Black]

if the earth span at 100rpm, light would still get to the earth.

 

[Jet Black]

also velosity is not the same thing as angular velocity... you can't spin at the same rate something moves, because there is no rate to move. and what do you mean by the universe? all of it?

 

[notto]

So much for "literal 24 hour days" 6000 years ago for creation.

 

[JohnR7]

also velosity is not the same thing as angular velocity... you can't spin at the same rate something moves, because there is no rate to move. and what do you mean by the universe? all of it?

The expanding rate of the universe, the hubble constant.

As far as the rate of spin, I was meaning how fast someone would be moving, if they were standing at the equator.

then your knowledge of physics is really poor, and my suggestion is for you to not comment on such matters. there is nothing at all to suggest that the earth would ever have spun at high speed, in fact it is physicaly impossible, since it would have just pulled the planet apart and even if it were possible, and the earth were spinning at such a rate that the equator was moving at near the speed of light, light would STILL get to you.

Furthermore your last line is just completely pointless, it stands alone and offers nothing other than to say it is a really poor understanding of physics.

Acourding to one of my geology books
the Proteroziac day was 18 hours long, and that the earth rotation has been slowing down 2 seconds every 100,000 years.
Tidal Friction is the cause of the diminishing rate of spin. Supporting evidence is from John Wells who recognized that the fine lines on the exoskeletons of coral fossils represents daily secretions of calcium carbonate.. Wells could discern coarse monthly bands, related to breeding cycles during which time less calcium was secreted. There were also broader annual bands indicating seasonal changes...WElls counted growth lines on several species, found the count 360 lines in the space of a year.

compared to 398 annual growth bands of DEvonian coral this mean 33 more days to the year than the present

also studies of tidal rhymites have confirmed this also, of 18 hour days during late Proterozoic 900 millions years ago

there is nothing at all to suggest that the earth would ever have spun at high speed.

We were talking about the rate the earth was spinning at before it began to slow down.

 

[ReUsAbLePhEoNiX]

We were talking about the rate the earth was spinning at before it began to slow down.

Maybe before noahs flood the earth was spinning so fast, its what held up the water canopy (firmement), as it slowed the water fell back down ( the flood).

I made up a new creation theory!! Hurrah for me.

 

[Jet Black]

look, John, this statement is complete rubbish:

If the earth was spinning at the same rate the rest of the universe is moving, then there would be no light on the earth.

 

[worship4ever]

I know that the light would get to you still, though the rate of speed at which the earth would rotate is kinda quick. I wouldn't say i dont know anything about physics, k, you need to keep your place dude. Your assuming again, like usual.

 

[worship4ever]

And do all of you think that creationist think the earth is 6000 years old? You guys act like every creationist thinks this way, again, assuming is not good. Your misconcepts of so called religion is highly screwed.

 

[Jet Black]

do you have a point to make?

and I am not saying all creationists think the world was born 6000 years ago, just that those who do believe this are basing their thoughts on higly flawed premises.

 

[Arikay]

Well, the most common creationist is the YEC. However there are others, like the 6 dayer (a type of YEC), the OEC, the Gap theory creationists and the IDists.

I often wonder if the most common is a YEC because the most common websites or creationist preachers are YECs.

 

[JohnR7]

look, John, this statement is complete rubbish:

Perhaps you would like to explain why we can see an ancient universe? The only possible explaination is that we are moving away from the beginning at just ever so slightly less than the speed of light. But for the most part, the matter and light are traveling together though space. It has been refered to as energy and mass as in E equals MC2.

[Jet Black]

the beginning is in all directions.

 

[JohnR7]

look, John, this statement is complete rubbish:

Maybe it is not worded properly, or my grammar is not perfect enough for you. But to say that the earth was not moving or spinning at the same rate as the rest of the universe before it began to slow down is what is rubbish.

 

[Jet Black]

no it isn't. your physics is just appalling in this matter, and is so far from anything that evidence suggests, that the easiest way I can debunk it is by handing you a primary school science book.
