https://en.m.wikipedia.org/wiki/Alcubierre_driveQuoted from link above:

"Rather than exceeding the speed of light within a local reference frame, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel. Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination faster than light would in normal space.[1]

Although the metric proposed by Alcubierre is mathematically valid (in that the proposal is consistent with the Einstein field equations), it may not be physically meaningful, in which case a drive will not be possible."

(I have actually explained the following logic in previous posts but as I cannot be bothered to trawl back and identify which posts these were, it follows that you will be even less inclined, so I will explain again.)

My model proposes that the metric is not a phenomenon of geometry and that the metric is in fact purely a gravitational time dilation effect. This identifying GR's interpretation of time dilation as misconceived, (is it 'relativistic gamma'? ...struggling with terminology here), and stating this minuscule increase in the rate of time at elevation as a mass near mass phenomenon, rather than the result of radius location conditions.

My model proposes that a rocket leaving a gravitational field will experience mass near mass effects that will increase the rate of its time by a minuscule amount, and that as it becomes less affected by the greater mass, this increase in its rate of time will drop. This being because it is travelling through reference frames of slower and slower time.

Light, remaining at 'the speed of light' - when travelling through these reference frames - covers 'less distance' in these slower rates of time. Essentially, the speed of light is going slower.

The rocket, maintaining its speed of x mph - this defined by the rate of time in earths gravitational field - is now pushing up to a higher percentage of the speed that light is travelling at in those reference frames. As a result of travelling at a higher percentage of the speed of light, Special Relativity effects will kick in at proportionally higher percentages causing the rocket to experience its time as even slower. Although the rocket will experience a length contraction of its journey from its own point of view, the further slowing of its own experience of its time will make the journey appear longer in distance.

If the rocket can reduce its speed proportionally to the slowing in the rates of time found within the reference frames it is travelling through, it will avoid the increase in the percentage of its speed in relation to the slower speeds of light in those reference frames, resulting in the slowing effects of Special Relativity being controllable.

All I have done is make an addition to the equivalence principle stating that the speed of light is only constant to the ratio of a length of a second.

So...in my model, FTL by current thinking standards would be entirely possible. The mechanics of it wouldn't actually be that a rocket would be travelling faster than the speed of light though, just that the geometry of distance that one imagines there, is not there, and it would be the 'time distance' that we are travelling faster. And...in case you might of missed it...yes that's right, just by quite simply travelling at 'slower' speeds.
