The acceleration produced by the solar effect is a function of surface area, light intensity, and reflectivity. Solar sails work very well because they have a lot of surface area, a high reflectivity, and a a direct incidence angle to the sun. Couple that with a low mass, then F=ma, will give you a force large enough to propel a spacecraft in "human time-frames".

Every celestial object around the sun experiences these effects. The effect on the Earth is reduced by a spherical reflection, atmospheric absorption and the fact the Earth is not a perfect reflector. Light hits the Earth every day. Every photon that hits the surface and reflects off of it imparts a little kinetic energy. Couple that with a huge mass you will get a small force. This is why the Earth's orbit is "measurably" constant.

If you make the evolutionary assumption that Earth is a billion years old, you have to accept that the Earth would of been under this solar effect for a billion years.

This small change in kinetic energy is cumulative, and over the years it adds up to a huge change in velocity. We do not see this, so therefore this evolutionary assumption is in violation of the laws of physics PERIOD.

Do the math. No matter how small an acceleration value you use, you will see the Earth's orbit is unstable over a "cosmic" time-frame. The only solution to this dilemma is to change your ASSUMPTION that the Earth is a billion years old because you cannot discount the empirical evidence for the solar effect and our measurably constant orbit.

If evolution is true then classical physics is false and all the hard empirical science we have developed is wrong. The assumption that the solar system is only thousands of years old DOES fit because this solar effect would not of amounted to anything measurable in this tiny time-frame.

Thanks for the critiques. It has been good sport, Because this is a revolutionary insight I think it is foolish to continue without writing a paper on it. I have a much more important missionary project on the plate now. As soon as I finish that I will take the time to do a rigorous write it up. I will probably get crucified, but if I cause a few people to challenge some of their preconceived notions it will be worth it.

PS: Vaderetro, I used the intensity of light at 1 AU. For evolution to be correct the Earth must have been at approximately this distance from the sun for a cosmic time-frame. All I have to do is show that the solar effect exists, and over a "cosmic time-frame" it will move planets. My numbers did that by many orders of magnitude to spare.

I'm sorry, I really must have missed something.

The ratio of a/g is the ratio of the acceleration from the solar wind (in the + r direction, outward) to the acceleration due to the sun's gravity (in the -r direction, inward).

If a/g > 1.0 the body accelerates away from the sun
If a/g = 1.0 the body is in static equilibrium, and just sits there until something else happens.
If a/g < 1.0 the the body accelerates towards the sun.

This a/g ratio for the earth was roughy 1.63E-14, or
0.0000000000000163. This is much less than 1.0. This means that the earth must offset the sun's gravity by means of an obital velocity, if it is to avoid plunging into the sun.

Were a/g > 1.0, our orbit would not last a minute, and we would be soaring out into space along with everything else in our solar system.

That's how I am reading this. Where have I made a mistake?

Everything I've been patiently explaining is still true; the bigger a thing gets the more squishy it is and the more it absorbs energy internally rather than rebounding elastically. Conservation of momentum is easily observed for small, elastic-rebounding things but it has trouble in high-friction environments. (It's actually still holding, but the momentum changes are disguised as heat within macro objects.) The Earth is very squishy. Especially its clouds and oceans.

But I'm going to try a whole other viewpoint, since it seems you've got that one barricaded and nothing is getting through. You concede that the push must be very, very, very, very tiny. It is that. (For reasons I've beaten to death I suspect it is close to zero. Note that a billion times zero is still zero.)

At any rate it is below noise level.

There is a noise level. The Earth is struck daily by space objects of non-trivial mass and momentum. The tiniest imbalance in that bombardment utterly swamps your trivial, utterly unmeasurable solar sail effect. Then there's the gravitational pull of near-neighbors the Moon, Venus, and Mars.

You can't have a cumulative effect from a "signal" that's dwarfed by the noise. It doesn't accumulate. It never goes anywhere.

Lest I forget: yes, the Earth is still at one AU from the sun. But if it ever does move out to the orbit of Mars the solar pressure won't be so much. You pushed it out to 20 gazillion something-or-others with no decrease in solar photons. That's another way your answer is wrong. Not that it matters.
