There's something rather strange about the idea of leaving the Solar System.
We often imagine that, with enough technology, we'll eventually build a spaceship capable of reaching another star. But perhaps the interesting question isn't, "How do we build that spaceship?"
The real question is: *What happens when we simply try to make it go very fast?*
Let's consider a speed that already seems almost absurd: 20% of the speed of light. Even at that speed, reaching Alpha Centauri would still take nearly twenty years.
And then there's a much less spectacular, but far more serious, problem: dust.
A tiny grain of dust that encounters a spaceship traveling at a significant fraction of the speed of light is no longer just "a bit of dust." The energy of the impact becomes enormous. At these speeds, even microscopic particles can become a major problem.
So, in this video, we're going to do something very simple: follow the numbers.
We'll start with the record speed achieved by the Parker Solar Probe, then we'll look at what changes when we push that speed to a much higher theoretical limit. We'll see what this means for interstellar travel, for the potentially habitable worlds around us, and perhaps even for an age-old question: *If the Universe is so vast, why don't we see anyone?*
No need for science fiction. No need to imagine impossible engines.
Just a few laws of physics, a few calculations… and what they actually tell us.

C'est pas une course, ça sera une aventure.
^^
L'humanité va quitter la métrique de Lorentz (en c carré) et passer directement par la métrique de Kozyrev (en c cube) pour se déplacer, indépendamment de notre espace-temps.
Pour accomplir cela il faut un appareil utilisant les disques contrarotatifs internes de Lovelace.
Heureusement, nous disposons en MHD de 3 formules de puissance (en watt) pour accomplir cette ambition.. légitime.
Un vaisseau exotique a été vu et filmé au-dessus de Hong Kong en 2014, presentant une formule contrarotative centrale tout le long de l'appareil.
