Einstein said that gravity went away in free fall.
Fall is push gravity manifesting. It does not go away. Weight does.
In space weight goes away not the gravity field.

No jan. The Earth falls around the Sun and has tides.
The Moon falls around the Earth and gives tides.
Orbiting is not pulling. It is acting on center instead.

Wobble is some apogee or perigee effect what accumulates 
displacements about a rotational axis starting a rotation.

I.e. the usual wobble is zero, ..., but rolling is just an un-reciprocated 
wobble, where the orbit is usually reciprocating in the usual sense, 
or "for the swing-set".

Physics isn't a closed system so even trains and cars driving around 
of course input that work into the Earth's rotation, with respect to 
adjusting at all the rotational then linear, inertia.

With rockets for example linear then rotational, ..., to Earth.

For the sonic, it's like, yes the tree in the forest that falls does 
make a sound:  it's just eventually the ocean in the shells is louder.

Sound is pretty clever in terms of sound inputs, light inputs, 
accelerometer inputs, ..., sense usually.

Here the point for accelerometers and levels is as various.

The gyroscope is a remarkable instrument and if it wasn't for 
our erector set, gyroscopes, optonic leaf globe, plasma globe, 
superconductor ceramic and paste, after logs, blocks, ..., not 
having a gyroscope and much practical experience riding a bicycle, 
it would be for the visualization of the gyroscope, that a 
sufficiently spinning gyroscope, does not wobble (fall down).

a pendulum goes back and forth because of the earth's wobbling, right?

the earth moves left and then to right...it's wobbling!

 

a pendulum goes back and forth because of the earth's wobbling,
right????

The magnetic moment is really something, for a planet, 
Earth and its magnetic moment is quite distinct.


The other day I went to a book-store and asked if they had any sun-dial books.

The stellar, is the nearest candle.

It's much brighter in Earth's orbit than out past Earth orbit.

The Earth's orbit is a reference cylinder, i.e. it's a planet, 
though given spherical cows it's tumbling dice.

The Earth, and Earth-Moon, and its LaGrange points, 
and Earth-Sun and its LaGrange points, mostly leaves 
most wobble, from other planets, entirely reduced to 
those points.

This though is a very simple model where orbits as elliptical, 
as of a circle of the same length, that apogee and perigee 
are no different or that they are different:  equilibrium.

The radiation reaching the Earth from the Sun is a linear 
function of the distance from the Sun to the Earth, 
in a simple model of stellar pulsation that its output is 
a constant, and motion around it a circle.

I.e.:  presumed constant, it's "linear", vis-a-vis the 
highly elliptical, or, the highly non-linear.

 Linear over time its input to the Earth:  energy from the Sun.

What's really great about that "the Earth tilts to explain 
seasonal differences, and, it's a constant tilt, and it is 23.5 
degrees, and my- where did the time go-, it's really great 
that instead of wondering over the rate of any tilt of the 
Earth in its reference cylinder, it's 23.5 and whatever calendar 
arithmetic I wrote out from it would be accurate either way".

Compared to 102.5 or something as a perfect constant, ..., angles.

It's a wonder more meteors don't _hit_ the Earth.  But, courtesy 
geologic time, the last time that happened was geologic time ago, 
here though we often talk about recorded history and 6,000 years 
while Homo sapiens sapiens has at least evolved 60,000 to 240,000 years, ago.

It's usually presumed "planets are mostly independent each in their 
orbits, as if they were alone".  Though, of course syzygy is a real effect.

Anyways the accuracy of course of long-term ephemeris can be 
read off from the global sun-dial array - as expected each of the 
accuracies of those dials would be the same over time, and any 
differences would be as according to reference measurement.

The Sun of course is assumed to be a reference sphere and center 
of mass, its drift in its frame or, for, parsecs, are 0 and none, resp.

"Gravity" doesn't do anything except "the field gravitates".  
Though, it's more that the field, "gravificates", that would be 
work, wobbling is deviation from an axis, rotation.

Allais effect showing planets interact that there's, "less 
gravity in the center", of being aligned the alignment, 
this is a classical experiment showing a fall gravity.

Also much "rotating" is "counter-rotating".

Do you know the real reason why the Earth wobbles? I'll explain...

put 8 or 9 balls on the water of your bathtub, swimming pool, lake,
ocean, etc..

and you will notice a lot of wobbling (espcially in an ocean).

Space...is an ocean, with balls on it's surface. That surface has waves
throught the universe. The waves make the earth...wobble.

Space is wet. Ask any fish.

Of course the fish would say, you live in a ocean called air. ain't you
wet?

Then the fish would say..."Why are you wearing what looks like a fish bowl over your head?"

Then you tell the fish, "If you enter my world...you going to need a fish bowl!"

And the fish sez, "Don't you mean a spacesuit?"

and you sez, "No, you'll need an Earth suit, we call it a fish bowl."

and the fish ez, "What do you wear in outer space?"

Looks like a fish bowl also..

then the fish asks, "What do aliens from outer space wear?"
