Right---

Being a physics 'lay person', as it were, I was using the traditional definition for 'acceleration'.

Nope. Still stands. The fact of historic world population growth from Christ to the present is exponential and that means evolution is impossible because it establishes a record that can not be changed and makes it impossible for the beginning of the exponential growth curve to have started significantly sooner than it did. You are toast and need to admit you've got a big problem. You need to make up another "just-so" story so that population growth stays flat for millions of years and then all of a sudden starts to grow at an exponential rate to the present. But of course you can't do that because it would expose the myth of evolution for the fraud it is. Just one of 99 reasons why evolution never happened.


John, this is just dumb. You are stuck on your cherry picked time period. Humans have not even speciated in the last 2000 years so no macro evolution has been involved anyway.

And why are humans different? Why have all animals not proliferated at the same rate? Other species go through periods of exponential growth but it never lasts.

Average growth of a species over its entire existence is zero. It starts with a small group of members and ends with zero. Species growth, from historical data, is a zero sum game. The BEST a species can do is fill a niche for a time and leave new species in their wake.

It is a fact that humans have been around for millions of years. You have never refuted that nor can you. It is a fact that populations of humans have waxed and waned till a plethora of factors have lead to unsustainable human growth.

Your 99 reasons are down to 00 reasons. You have, objectively, failed in your quest, just as so many other fundamentalists have.

Is that your final answer? Will you testify that you were not mocking but are dead serious?

All objects in free fall (gravity implied) experience a constant state of acceleration due to gravity.

Only morons claim an object can accelerate and decelerate at the same time. An object can remain in motion while decelerating, but not accelerate and decelerate at the same time.

If the above is not true, then it should be easy to explain that concept, right?

How would you teach children, please explain.

Children mock what they cannot do,--be.
they also cannot use the words of the hypothesis to refute it, but hey, that's what children do.
Earths rotation rate around the barycenter between the earth and sun is about 67,000 miles an hour. Earths spinrate on its axis is right at 1,000 mph. Notice that earth has a strong atmosphere and strong gravity as well. However, earth has water all across its surface, where most other planets don't, so that likely plays a big part in having a strong atmosphere.
Then look at earths moon, it's rotational rate around the earth and its barycenter is, very slow, 1.03 km/s just as the moons spin rate on its own axis is about 13 miles per hour. Notice that the moon has very little atmosphere and very little gravity. Both axial spin and rotation around earth are slow and the atmosphere and gravity are very weak. 
Let's then look at the rotation rate of Venus, around the barycenter and the sun at 78,341 miles per hour, that's faster than earths rotation rate around the suns barycenter, of course, Venus is closer to the sun and being closer to the sun, Gravity becomes greater according to Newtons second law of motion, so how is it that Venus is 90% of the size, mass and density and it's gravity is 90% of the earths. That cannot be, Venus is 1/3 closer to the sun. If Newtons 2nd law is correct, venus should have a much greater gravity.
Then it's axis spin rate is very slow, at just 6.5 km/hour, but I add in, that Venus has an atmosphere where the winds roar across the planet at 220 miles per hour, approximately. This will prove important, because in my  hypothesis, axial spin rate creates atmosphere. However, with Venus as a model and a tiny axial spin rate, there should be no atmosphere. Volcanoes to the rescue, it seems those and more chemicals are creating the venus atmosphere. 
Next is Mercury, it spins on its own axis at only 6 mph and according to my hypothesis, mercury should not have much of an atmosphere and it doesnt. However, it's rotational rate around the suns barycenter is 106,000 miles per hour, meaning, that according to my hypothesis, Mercury's gravity should be higher  and by the way, it is 2/3rds closer to the sun than the earth, so it's gravity should be very high, even for its size, but wait a minute, mercury is 40% of earths size. Gravity on Mercury is only 38% of earths. According to Newtons second law of motion, gravity should be much higher on mercury.
Mars, now here's something interesting. Mars and earth traverse their orbits around the sun and their respective barycenters at about the same velocity. Both also spin on their axis at about 1,000 miles per hour., and yet, mars is half the size of earth. Mars gravity is 38% of earths gravity, which is less than half of earths, but once one factors in that mars is further away from the sun, it's easy to see the other 12% loss in gravity, considering Newtons second law of motion. The mars spin and orbital rate match up with its gravity and atmosphere, according to my hypothesis.
On rover curiosity, today's scientists claim that mars gravity is only 1/6th of earths, so who is right, today's scientists that must know mars gravity to land the 2000 pound rover curiosity from a hovering craft, or newton and Einstein, that claim mars has a gravity of 38%?
According to science, we do not rotate around the sun, we rotate around the barycenter.
Hypothesis by ,--
Jim Ryan 
What is the mathematical relationship between planetary spin and gravity?

If I'm NOT spinning, does my body have gravitational pull? If I start spinning, does my body's gravity increase? How much? We have equipment that would be able to detect gravitational fluctuations. I just want to know the math so we can test it.

Is slowing down a change in speed? If so, then it is acceleration (any change in rate or direction of motion). The fact that you continue to say that the colloquial definition of "acceleration" is the same as the scientific definition of "acceleration" after having the definition given to you many times merely shows that you are dishonest.

An object can accelerate in one direction and decelerate in another. Try to wrap your mind around three dimensional space.

This is the exact exchange regarding the dremel tool and Dogen:

“Remind as again how a dremel tool is proof positive that spin doesn't matter. Koo-koo...koo koo...koo koo..”.

“His claim was that spin generates gravity. Are you suggesting that spin generates gravity, too?”

“No, but a dremel tool has so little mass it is hardly an argument.”
Dogen wrote:
“I refer you to an elementary physics book.”
Dogen wrote (commenting on the same UC quote):
“But it SHOULD if it is spinning fast enough. Do you not get anything?
Spinning = gravity.”
*End*
There is no hint that Dogen was mocking anyone. Dogen was clearly establishing that he believed that a spinning dremel creates gravity and then he acted as though he could prove it with a reference to a physics book. Then he stated –without any hint of sarcasm – that it SHOULD (notice the caps!) if it spins fast enough. And then he further emphasizes his position with an emphatic “Spinning = gravity". And you go along with this dimwit that lied about it later when he realizes he was wrong and squirms out of it like the little twerp he is? That makes you just as stupid and dishonest as he is! Shame on you LG!
My statement stands. You're a liar.

I just find it surprising that you'd actually admit that Psychopath's "hypothesis" is bullshit. You've been so adamant about not discounting ANYTHING said by those against whom we argue. But, apparently this time it was so batshit stupid you simply couldn't pretend any more. Good for you for having at least a glimmer of honesty.

I never said that, so don't put words in my mouth liar. And the "Spin = gravity" is Dogen's quote alone. He even referred me to an elementary physics book and told me, "Don't you ever get anything?". You people can't possibly keep all you lies straight.
None of you voodoo darwin zombies can ever be trusted. Every one of you are cut from the same soiled cloth.
Right. You think "spin = gravity" is bullshit. Psycho says that spin generates gravity. You said it's wrong when I asked if you agree with his "hypothesis." Are you saying it's wrong but NOT bullshit? Really splitting hairs, ain't ya?

I think it is the concept of "acceleration" that is throwing him. He is still stuck on "speed" rather than acceleration, methinks.

OK. So what I get out of this is that "acceleration" and "speed" are not the same. So the earth is in a constant state of acceleration around the sun (that is, it is in freefall), but its speed remains the same.

Yes. Until terminal velocity. You could just google "free fall" and hit the wiki page, which explains everything you might need to know about free fall and acceleration.

Yeah, I learned this here too:

"Acceleration" is any change in velocity **OR DIRECTION**.

As the earth is in orbit around the sun, it is not traveling in a straight line, and is therefore always "accelerating".

Yes AND the 'speed' in any given direction is changing constantly.

If I spin in the opposite direction from you, do I experience anti-gravity?
