    Frame Ftl
In summary, the conversation discusses the concept of a FTL drive that works only with respect to the CMB rest frame and how it could potentially eliminate temporal paradoxes. Further discussion delves into the implications and practical applications of such a drive. However, it is ultimately determined that this concept is not based in reality and should not be labeled as "correct."

Lets assume a FTL drive that works only with respect to CMB rest frame (technobabble probably something about inflation/dark energy). So drive speed would vary depending on whether the ship is moving along CMB peculiar velocity (371 km/s towards constellation Leo), or against it. Would that be enough to get rid of temporal paradoxes? How would such a drive work in practice, for various directions of movement, round trips..?

Once you posit a situation that amounts to "if the laws of physics did not apply, what would the laws of physics say about <insert nonsense of your choice>" followup questions based on that are not going to be particularly meaningful.

In an alternate timeline, it were maybe possible to view CMB as a preferred frame, when we talk about speeds (like on Earth, surface is considered a preferred frame when we talk about speed).
But it change nothing, Lorentz transformations, observations led to SR remains the same.
Of course in usual SF and many debates around the net, FTL is only the illusion of time travel, it don't let really alter the past.

"Correct" is not really a term that should be applied to something that does not describe reality. I think you more likely mean "is it internally consistent?" I spent very little time looking at the site but he seems to have given it a lot of thought so it may well be internally consistent.
 

1. What is FTL with a preferred frame?

FTL (Faster-than-light) with a preferred frame is a theoretical concept in physics that suggests the possibility of traveling faster than the speed of light by choosing a preferred reference frame from which to measure the motion of an object. It is based on the idea that the laws of physics may be different in different reference frames, allowing for the potential for faster-than-light travel.

2. Is FTL with a preferred frame possible?

There is currently no scientific evidence to suggest that FTL travel is possible, and the concept of a preferred frame is not widely accepted in the scientific community. The theory of relativity, which is a fundamental principle in modern physics, states that the speed of light is the maximum speed at which all matter and information can travel. Therefore, it is highly unlikely that FTL travel with a preferred frame is achievable.

3. How does FTL with a preferred frame differ from other theories of FTL travel?

FTL with a preferred frame differs from other theories of FTL travel, such as the Alcubierre drive or wormholes, in that it relies on the concept of a preferred reference frame and the potential for different laws of physics in different frames. These other theories are based on manipulating space-time or creating shortcuts through space, rather than changing the laws of physics.

4. Are there any experiments or studies being conducted to test the concept of FTL with a preferred frame?

Currently, there are no known experiments or studies being conducted to test the concept of FTL with a preferred frame. This is due to the lack of scientific evidence and acceptance of the theory in the scientific community. As of now, it remains a purely theoretical concept.

5. Could FTL with a preferred frame have any potential implications for space travel or communication?

If the concept of FTL with a preferred frame were to be proven possible, it could have significant implications for space travel and communication. It could potentially allow for faster travel between distant locations in the universe and enable real-time communication over vast distances. However, until there is scientific evidence to support this theory, it remains purely speculative.
