Alright, now that the peanut gallery has quieted down a bit, let's discuss a real-world applicable technique for traveling at high fractions of c.

No, it's not practical with our current technology.

No, it's not easy to do.

Yes, it requires a metric buttload of energy.

We all know the Higgs field is a scalar tachyonic field, and therefore the Higgs boson is a tachyonic spin-0 particle.

I've written about the Higgs prior:

In the earliest moments of the universe, the weak force (at the time combined with the EM force into the electroweak force) was a long-range force. Then, as the universe expanded and energy density fell, the electroweak force symmetry-broke into the weak fundamental force and the electromagnetic fundamental force, giving rise to the Higgs field and thus fermionic mass. Before electroweak symmetry breaking, there were 4 species of Higgs bosons in existence (the only things which had mass), but when electroweak symmetry breaking took place, three of them underwent quantum mixing (via the Higgs mechanism) with the isospin force and hypercharge force which existed at the time, making the W^{-}, W^{+} and Z^{0} bosons massive, and leaving only the H^{0} Higgs boson today (the H^{0} Higgs boson couldn't interact with the EM fundamental force, which means we were left with one Higgs boson and massless photons). The Higgs boson is virtual today because the universe's energy density is too low for it to be concretized. It pops into existence for a brief moment, but its energy density is so high that it immediately decays via destructive interference, smearing its energy back into the QVZPE field, leaving behind a molasses-like Higgs field instead which we sense as the other particles having mass.

While normal fundamental particles require energy to be added to them in order for their momentum to increase, tachyonic particles slow down as energy is added to them (this is why the Higgs field acts as it does).

While normal fundamental particles have a speed

*limit* of c, a tachyonic particle has a speed

*minimum* of c. The Higgs field, being a scalar field, doesn't really propagate anywhere, since it's ubiquitous throughout the universe, but any perturbations within the field must travel at a minimum speed of c... we know it travels at exactly c. We've never experienced it traveling faster.

This is part of the reason why when a Higgs boson is forced to undergo tachyonic condensation (which occurs at energy levels at or above 125.09 GeV/c

^{2}), it immediately smears out its energy back into the Higgs field.

Now, if your hypersurface of simultaneity is in a space-like frame of sufficient magnitude (ie: you're moving through space fast enough), a tachyon in that same frame can actually appear to be traveling backward through time.

We can exploit these phenomena to achieve high fraction of c space travel. If we could generate enough power such that we could continually power a collider of sufficient energy so that we could generate a continual flux of Higgs bosons, and immediately chuck those Higgs bosons into a well-shielded Casimir cavity (which has an artificially lower quantum vacuum expectation value), we'd see the Higgs lasting longer because it takes longer to decohere (ie: the lower vacuum expectation value within the well-shielded Casimir cavity has a lower quantum entanglement cross-section, and thus slower decoherence of the Higgs particle and thus it takes longer for the Higgs particle to smear its energy back into the Higgs field).

At the same time, it would attempt to travel backward through time (for a sufficient velocity of the spacecraft to begin with... for slower velocities, it'd remain on the present-time hypersurface of simultaneity (ie: it'd remain in the present time), and for even slower velocities it'd travel into future hypersurfaces of simultaneity just as normal matter does) because it would remain outside the future light cone (you'll note the light cone is sloped at a 45 degree angle because light travels through space at 1 c (light-like curve)... anything slower is inside the light cone (time-like curve), anything faster is outside the light cone (space-like curve)).

You'll remember in a prior post I wrote:

In a paper by Oziewicz (referenced in the second link above), he states: "Minkowski, and then Ivezi'c, observed correctly that if a Lorentz transformation is an isomorphism of a vector space, then the entire algebra of tensor fields must be Lorentz-covariant. An active Lorentz transformation must act on all tensor fields, including an observer's time-like vector field."

So we must make the Higgs particles not only persist in an artificially lower quantum vacuum expectation value environment, we must make them undergo a Lorentz transformation. We could do this most easily via a vectoral Lorentz transformation... merely making the Higgs particles (ejected from the collider in a straight line) go in another direction within the well-shielded Casimir cavity... and by the time that's all complete, the Higgs would have smeared out back into the Higgs field.

Of course, getting the Higgs particle to go in another direction is going to be the hard part. It couples fairly well with the muon, and since the Higgs particle can decay into muons, we've got a ready-made supply and means of deflecting the Higgs. Now all we have to do is control the muons. Fortunately, the muon being a heavier species of electron makes that fairly straightforward via a magnetic bottle.

This Lorentz transformation means the Higgs tachyonic particles attempting to travel backward through time will also slow time for anything else in the same frame as those tachyonic particles... in this case, the entire spacecraft.

Thus, while you'll never exceed c with a regular matter spacecraft (and you'll never be able to build a spacecraft from tachyonic matter... and even if you could, it'd never travel slower than c, and would smear itself out into energy in very short order), you can slow time in the frame of the spacecraft.

Thus, from the frame of an external observer, the craft travels, say 100 km/s, whereas from the frame of the spacecraft itself, it'd travel the same 100 km in some fraction of that second.

In effect, by slowing down the evolution of time for the spacecraft, you're effectively increasing the speed of that craft in the frame of the craft's crew.
