But Low Energy FTL travel is far greener for our Galaxy than HE FTL. With HE FTL, just one mistake can born new supernova. Moreover, it requires year of whole star energy for singe travel. 90% of stars turned dark just because of that. I will call you "Dark Lord" from now.

> More recent measurements seem to point to more encouraging values for the α-sticking probability, finding the α-sticking probability to be about 0.5% (or perhaps even about 0.4% or 0.3%), which could mean as many as about 200 (or perhaps even about 250 or about 333) muon-catalyzed d-t fusions per muon.[29][30] Indeed, the team led by Steven E. Jones achieved 150 d-t fusions per muon (average) at the Los Alamos Meson Physics Facility.[31] Unfortunately, 200 (or 250 or even 333) muon-catalyzed d-t fusions per muon are still not quite enough even to reach "break-even," where as much thermal energy is generated (or output) as the electrical energy that was used up (or input) to make the muon in the first place. This means, of course, that not nearly enough thermal energy is generated thereby to be able to convert the thermal energy released into more useful electrical energy, and to have any electrical energy left over to sell to the commercial electrical power "grid." The conversion efficiency from thermal energy to electrical energy is only about 40% or so. Also, some not inconsiderable fraction of that electrical energy (hopefully not all of it) would have to be "recycled" (used up in deuteron particle accelerators, for example) to make more muons to keep the muon-catalyzed d-t nuclear fusion fires burning night and day.[32] The best recent estimated guess of the electrical "energy cost" per muon is about 6 GeV (billion electron Volts), using deuterons that are accelerated to have kinetic energies of about 800 MeV per nucleon, with accelerators that are (coincidentally) about 40% efficient at taking electrical energy from the Alternating Current (AC) mains (the plugs in the wall) and accelerating the deuterons using this electrical energy.

Yep, it's challenging. Maybe this rate can be improved by applying alternating voltage to reactor. Muons are charged particles, so they can be accelerated further. (Just idea)

Yes, wars are not simple. Fog of war may make it blurry, or enemy may fool each other. For example, soviets shelled their own territory in Finnish war, to pretend that they were attacked first, so they are defending. Russians are using same thing too: they blown up their own buildings to blame Chechen and then started second Chechen war, or, in case of Russo-Ukrainian war, they pretend that Ukraine will be swallowed by NATO and then European and American homosexuals will freely fuck Russian-speaking Ukrainian children, so Russians are invaded to protect Ukrainians!

However, this should not alter your moral compass. Those, who defend themselves, have moral rights to wipe the attackers or invaders.

All that is because of lack of understanding of underlying physics. Standard model is used as substitute to physics, which results in explanations like that: "there is no Everest (physics), it's just excitement in the height field (model). Gravitation (physics) bends space-time (model), so students just follow the shortest path.", and so on.

Unlike regular waves, photons are topologically stable, like smoke-ring kind of wave. Google hopfions for example.

If you like hydrodynamic quantum analogs (walking droplets), then you may see that droplet may escape it pilot wave sometimes. In such cases, pilot wave continue to travel in same direction for some time. IMHO, it's similar to how photons are formed: electron creates pilot wave, then escapes it, similar to Cherenkov radiation.

Anyway, photons have special configuration, so they behaves differently than regular waves.

Gravitational waves, AFAIK, are not topologically stable at all.

I saw water-like behavior of a wave! I have no idea, how much molecules it contains, large waves have many cubic meters of water, but I'm pretty sure that quantum behavior is not limited to 5000 atoms. Waves, even very large onses, are moving energy in "packets". 1 wave - 1 quanta. So, what?

Photon is radio-wave (EM-wave). Typical photon is produced and consumed by a electron, so properties of photon produced by an electron are limited by the electron, also, our abilty to detect photonare limited by the electron. However, EM-waves in general are not limited by electron.

On smaller scale, electron interacts with other charged particles and with EM-field (the medium) via EM-waves. I'm pretty sure that electron is not staying stil, it's vibrating because of thermal noise. Vibration of charged particle produces EM-waves. Those EM-waves are not photons.
