If we are traveling on a globe around the sun at 67000mph, the 67000mph decreases and increases by 1000mph at the equator in 12hrs due to the globe spinning at 1000mph, why if we are doing this do we not feel this change in speed in such a short time when we should?
We would notice it, the sky, the sea would notice it.

Traveling on a train if you jump up you land in the same place if at constant speed, now spin on a roundabout in the train, your speed in that train changes in a short time as you spin towards the front it increases, towards the back it decreases. Spinning globe traveling 67000mph, you would feel a change in speed but don't why?

 
Say you have a truck, put a swimming pool in it, speed up from 0 to 500mph in 1.5hr, about 0.09mile per second change on average, that's faster then slower.
The water would notice.
It's not the constant speed that can be 0 to millions of mph, that's constant, it's the change of 0.09 miles per second change you would notice.
You would notice it, the water would notice it,
The constant speed is irrelevant, it's the change in speed, the effect on a mass, a large body of water changing speed constantly to a max of 0.09mile p sec.
Gravity is not changing constantly to account for this, this speed change is local, different parts of the globe will have different speeds, as it moves around the sun and we spin, think, you on a globe, not you looking at a globe.
We agree on speed difference.
Speed 0.09miles p s isn't small,
Meters per sec?
In per sec?
Ft per sec?
Constantly changing?

No spin guaranteed, check out my video it's not great quality just puts the question in people's head that rotation of a globe is mad, working on another vid on the same lines, better quality, will blow the globe model away with physics.

It's the globe with ?

Impossible ISS.
