Welcome to the fray Grizz
Branes will simply be a conjecture until emperically verified. Multiverses will remain foroever outside of our ability to detect emeprically and will be limited to an interesting theoretical possibility.
Or they will remain a mathematical convenience. Like dark stuffs ...
In the Scientific Enterprise theory and reasoning will always be subservient to observation.
Much of theoretical physics has outstripped observation, IMH(ysa)O, and really what we have are mathematically convenient models to explain what we observe. The basic problem I have is that math is not reality.
IIRC branes also obviate the need to invoke dark matter\energy because of the existence of stuff outside the brane. If this is so, I would think that one should be able to differentiate between the two by observations at a more local level: dark stuffs are supposed to take effect outside stellar systems; we have evidence of some anomalous behavior in the paths of satellites as they reach the outer limits of the solar system. Anomalous with regard to the current model that includes dark stuffs:
Pioneer anomaly - Wikipedia
quote:
The Pioneer anomaly or Pioneer effect is the observed deviation from expectations of the trajectories of various unmanned spacecraft visiting the outer solar system, notably Pioneer 10 and Pioneer 11. At present, there is no universally accepted explanation for this phenomenon; while it is possible that the explanation will be mundane”such as thrust from gas leakage”the possibility of entirely new physics is also being considered.
It seems to me that the brane explanation for the gravitational anomaly that originally invoked the mathematical concept of dark stuffs would operate locally and would explain this anomaly.
Another potential explanation is Weyl geometry:
IZWT
quote:
In this respect, it deals with the wider problem of epistemic legitimacy and the role of alternative theories in mathematical physics. An own alternative theory for cosmo-geometric models is proposed. From the point of view of the accepted standard theory, this alternative seems to be surprising and perhaps provocative.
Of course another explanation of the anomaly is god stuff ...
I was really hoping to hear the opinions of at least one ID supporter on the subject.
Probably the one most likely to tackle that is randman, and he is restricted to the shouting box forum (
Showcase), which has been fairly silent of late.
I believe the discord lies in misunderstandings of what types of truths each system is after. The assertion that the sun will rise tomorrow is neither true nor false - the truth of the statement is contingent - as are all scientific assertions regarding physical reality that have been born from observation.
It comes down to perceptions of reality and the various mechanisms used for different levels of perceptions, science, philosophy, faith. To me the various systems of perception that are closest to reality are those that are least in conflict with observations and most consistent with conclusions that extend beyond the reaches of science.
Enjoy
