# Does acceleration imply absolute space?

## Recommended Posts

I might have some basic misconceptions here, but hopefully what I'm saying makes sense.

So one of the ways proposed to have gravity in space is the rotating wheel space station. Thanks to centripetal force, occupants could feel acceleration on the inside of the rim of the wheel.

But it also seems like something can only be moving relative to something else. From the frame of reference within the space station itself, the wheel is standing still, and everything else is moving around it.

But suppose that the wheel was the only physical thing in existence. There is nothing it is rotating relative to. Wouldn't the people in the station still feel the acceleration of "gravity" though?

I've heard that Newton fixed this issue with the idea of absolute space, that the wheel would still be accelerating according to some objective points in space, even if there are no objects it accelerates relative to. But I've also heard that Einstein's relativity did away with the idea of absolute space.

So how is this problem solved?

Since the introduction of Special theory of Relativity (SR), Lorentz invariance has been a fundamental part of our description of nature. Over the past decades, this (Lorentz invariance) was tested and verified by many research groups and almost no Lorentz violation has been found. However, when we look at the Lorentz transformations, we can mathematically find that they are not symmetrical relations. In fact, the inertial frames are not symmetrical in relation to each other and as a result, there must be a reference frame. If the inertial frames are symmetrical in relation to each other, as the SR argues, some paradoxes and contradictions are happened. Hence, we need to find the misconceptions in this theory. Many researches up to now, focused on Zero-Point Field (ZPF) as a cause for many physical phenomena like mass, inertia, and gravity. One can argue that the Lorentz transformations can be applied only for the inertial frames, moving inside the ZPF and the inertial frames, being at rest in relation to the ZPF, must not bear the Lorentz transformations. In addition, we have found that the SR and General Relativity (GR) are not two separated concepts. They are one thing and the space-time of them are the same. In both cases, it is the ZPF, which curves around the accelerated body or a gravitational mass, causing changes in the body’s length, time, and mass.

In standard Newtonian mechanics, acceleration is considered to be an absolute quantity, in that it is not determined relative to any inertial frame of reference (constant velocity). This fact follows directly from the principle that forces are the same everywhere, independent of observer.
