you have rotation and revolution puzzled. that's ok, its a uncomplicated mistake, that sometime we are able to restoration. An merchandise rotates on its axis. A revolution, or an orbit, is a around (or elliptical) course around something else. each merchandise that exists in area has rotation. a minimum of realitive to something. Planet X, the version you're pertaining to... is fictional, so it could have any features the writers and inventors of it opt for... fiction isn't certain by way of the regulations of the universe. *If* an merchandise existed, that replaced into "hidden by way of the solar" it ought to achieve this on a particularly known foundation, if it replaced into at an somewhat specific lagrange element. That merchandise would could have a orbit comparable to Earth's, yet permenently on the different area of the solar. There are 2 problems with that Lagrange element. a million. via eccentricity of the orbit, whilst Earth replaced into at perihelion, the "Planet X" would could be at aphelion (and vice versa) ... Kepler's 2nd regulation tells us that this potential it would decelerate as we accelerated, and we'd velocity up because it slowed down, so the item in question would spend a sturdy fraction of hte year "peaking out" in the back of the solar, and being very truthfully detectable). 2. That lagrange element in unsatble in at 1AU, the gravitational perturbances of Mars, and greater importatnly Venus, would have brought about this physique to decay right into a distinctive orbit, decay completely and fall into the solar, or... if sufficiently small, be captured by way of yet another physique and become a satellite tv for pc. via fact of Kepler's regulations, all of us comprehend this merchandise would could have the best comparable semimajor axis via fact the Earth, meaning it is distance from the solar would could be 1AU. So sure, you're innovations-blowing, it is yet yet another nail in the already buried coffin of all of hte Planet X supporters that throughout the time of no way concept absolutely everyone who took a physics classification would examine their information.

Motion is relative.

The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity)

General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: In other words an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it.

Some of us are but that is not because of rotation.

It takes all day for the earth to spin once on its axis so that is no carnival ride.

As Sadie said, "Gravity".
Gravity is the key element to our non-dizziness world.
Its a true fact

Because we are rotating at the same speed and the earth is large enough it doesn't mess with our sense of equilibrium.

Because our gravity field travels with the planet.

The earth rotates soo slowly that we don't really realize it. Also, you are soo used to it, that you don't really realize it either.

Since Earth is so big we can't feel the Earth moving.
