Is the moon getting nearer ?

Wrong. The tides slow down the rotation rate of the Earth, decreasing its rotational kinetic energy. But energy must be conserved. It is translated into increased orbital distance to the moon. This is a long-understood effect.
Some is converted to heat too.
But don't press me further....I'm unfamiliar with orbital & tidle meckanics.
Criminy, I can't even spell it.

My understanding is that the amount going into heat is fairly small, and that the rest shows up primarily in the orbital effects.

Really ?

Your no seemed confident !

As he should. We have actual measurements, which always trump theoretical considerations, as well as a theoretical understanding.

On the other side, you have some meaningless equations which only show your lack of understanding of the issues involved.

We don't have anything unless you work for the department that deals with the measurement !


P.s My equations are simplified negative energy . My equations are correct to my theory .

A bit more information:
Lunar Laser Ranging experiment - Wikipedia

If you want the raw data set, it is available from this following:
LLR

Again, your opinion concerning your equations is based on your lack of knowledge in this area. Anyone with any experience in math understands them to be meaningless.

Your equations are absolutely meaningless... and I agree, they are definitely 'correct' for your 'theory'.

No. When you can't even do basic addition i don't think that anyone will take your "equations" seriously. You need to define all of your terms, you need to define all of your units, then you have to show that mathematically your concept gives the same results that we can measure in real life. And since you seem to have a huge problem with math i don't think that will ever happen.

Oh please , maths is added to the physics after the physics . Faraday an example .

My maths works and it is simple user friendly to explain process .

They can't measure mass for a very simple reason !
If that were the case, how could you know the Earth was gaining mass or the mass of the comic dust falling on it per year?

Mass is electrical charge and it doesn't matter how dense the mass is it will always measure 0 . The reason for this is A+B=0 .
That makes absolutely zero sense but doesn't seem relevant to the fundamental error in your OP anyway. Are you going to address the loss of hydrogen and helium from the atmosphere at all?

No, Faraday made an observation. Then he did countless experiments with measurements. Then he devised a formula whose math matched reality. You don't appear to know what to measure or how and you can't do the math.

In the world of physics you need to learn the math first.

No, you think again. The link provided in post 2 explains that it also loses over 50 thousand tonnes of hydrogen and helium to space every year.

This is explained by kinetic theory. The speed of thermal motion of the molecules, for these light gases, is so high* that for a significant fraction of them it exceeds the Earth's escape velocity.

That's why H and He disappear from the atmospheres of planets with modest gravity, while gas giants like Jupiter keep most of theirs.

*A kinetic theory result is that Temperature is proportional to thermal kinetic energy (1/2 mv²). From this it follows that, at a given temperature, in a gas made up of light molecules they have to be moving faster - to give the same kinetic energy - than in one made up of heavier molecules.

Well , I can't be correct on all things .

Example 1:
Joe has one pie. Betty has one pie.
Question: How many pies do Joe and Betty together have?
Answer 2.
Proof: 1 + 1 = 2
There, a simple, user friendly, easily explainable process.​


Example 2:
Betty's pie measures 12 inches across. Joe's pie measures 12 inches across.
Question: What is the radius of each pie?
Answer: Huh?!? That isn't simple. It's not user friendly. I don't need to explain the process because it has no bearing on my wisdom.​
