Actually, there's no physical evidance of length contraction to be noticed in our daily lives. This phenomena will not happen unless an object travels at a fraction of the speed of light, 1/10th of the speed of light (30,000,000 m/s) to be precise. we could just hope that one day, NASA will send a probe to space and use the Sun and the earth gravity wells to hopefully prove length contraction.
The resolution to the Ehrenfest paradox is that the contraction of a rotating disk in special relativity is not a paradox at all. The apparent contradiction arises from the different perspectives of observers in motion, but when taking into account the effects of time dilation and length contraction, the paradox is resolved. The contraction of the disk is consistent with the principles of special relativity.
Time Dilation and Length contraction (essentially the same idea, whenconsidering the sameness of time and space as dimensions - which is the crux of special relativity), and specifically the Precession of Mercury (which is predicted by General Relativity) [which forgoes the necessity of a background reference frame (an axis/coordinate system)] are examples of Relativity.
according to Einsteins special relativity
The special theory of relativity predicts that the speed of light is constant in all inertial frames of reference, time dilation, length contraction, and the equivalence of mass and energy as described by the famous equation E=mc^2. These predictions have been confirmed through various experiments and are fundamental to our understanding of the nature of spacetime.
Everything remains the same....I think
The significance of the relative speed of light in the theory of special relativity is that it serves as a universal constant, meaning that the speed of light is the same for all observers regardless of their relative motion. This principle leads to the concept of time dilation and length contraction, which are fundamental aspects of special relativity that explain how time and space are perceived differently by observers in motion relative to each other.
The concept of SR units, or spacetime units, is a fundamental aspect of special relativity theory. In special relativity, space and time are combined into a single four-dimensional spacetime continuum. SR units help measure distances and intervals in this spacetime, accounting for the effects of time dilation and length contraction at high speeds. This concept is crucial for understanding how objects and events are perceived differently depending on their relative motion, as predicted by special relativity theory.
Relativity is a theory that describes how objects and energy interact in the universe, while special relativity is a specific branch of relativity that deals with the behavior of objects moving at high speeds. Special relativity is a subset of the broader theory of relativity, focusing on the effects of motion on space and time. Both theories are interconnected, with special relativity providing a more detailed understanding of certain aspects of relativity.
At least special theory of relativity was published 1905

According to special relativity, you will first of all experience less time than slow stuff (time dialation). Objects around you will lengthen relative to your contraction (length contraction). Colour of objects around you will blue shift or red shift, depending if you're looking forward or backward (Doppler shift).
Einstein's special theory of relativity proposed that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum is constant for all observers. It also introduced the concepts of time dilation, length contraction, and the equivalence of mass and energy (E=mc^2).
