Relevance of Local Lorentz Invariance Violations

[stglyde]

What is the relevance of Local Lorentz Invariance Violations if they would be detected in any future experiments? Does it mean there is absolute space and time in the microscopic sector below where current experiments can't probe or other absolute parameters since there would be preferred frame already? In such case where lorentz symmetry were emergent, how do you connect special relativity being true at larger scale and preferred frame being true at smaller scale? Are they not in conflict since the traveling twin can already establish absolute time by referring to the preferred frame (where lorentz violations existed) and yet affected his age influenced by time dilation? Or is lorentz violations not related to preferred frame? Please don't share any papers. Just explain in your own clear words. Thanks.

Local Lorentz invariance violations refer to the idea that the laws of physics may not be the same in all frames of reference, as predicted by Einstein's theory of special relativity. This means that there may be a preferred frame of reference, where certain physical phenomena behave differently than in other frames.

If such violations were to be detected in future experiments, it would have significant implications for our understanding of space and time. It would suggest that there may be absolute space and time in the microscopic sector, below the scale that current experiments can probe. This would mean that there are certain fundamental parameters that exist regardless of the observer's frame of reference.

However, it is important to note that the concept of preferred frame is not necessarily in conflict with the principles of special relativity. In fact, there is a concept in physics known as "emergent symmetry" which suggests that certain symmetries may only be apparent at larger scales, while being violated at smaller scales. This means that while special relativity may hold true at larger scales, there could be a preferred frame at smaller scales.

In this scenario, the traveling twin's experience of time dilation would still be valid in the larger scale, where special relativity holds true. But in the smaller scale, where Lorentz violations exist, there may be a preferred frame that affects the twin's aging differently. This does not necessarily mean that the concept of absolute time is in conflict with special relativity, but rather that it may only be applicable in certain scales or contexts.

It is also important to note that Lorentz violations do not necessarily imply a preferred frame. There are other theories, such as loop quantum gravity, that suggest a different approach to understanding space and time, without the need for a preferred frame.

In conclusion, the detection of local Lorentz invariance violations would have significant implications for our understanding of space and time. It may suggest the existence of absolute parameters in the microscopic sector, but it does not necessarily conflict with the principles of special relativity. The concept of preferred frame may also be applicable in certain scales or contexts, but it is not the only possible explanation for Lorentz violations.
