At 195 decibles, the sound of a rocket launched into space can permantly deafen or kill anyone closer than two miles away.
In space however, the powerful sound pressure of 195 decibles remains while it conveniently cannot be heard.
For example, we don't hear our earth powering through space at 1.774 x 10^26kg decibles momentive-force, for the same reason. (29.78 km/s speed of earth through space X 5.957 x 10^24 kg mass of earth)
UVB at 384.2 nm and 780 terahertz divided by infrared at 886 nm and 338.3 terahertz = 0.4336. Our manned spacecraft is at least 40 meters long with a rotational center at 0.4336 of its length. This produces a 13% extended offset of the ships fuselage to one side only, providing non-coherent interference with dark matter at all times as the ship spins.
87% of the ship's fuselage spins centered on 0.4336 of the length and exhibits a coherent interference with dark matter.
The extended offset or drive tiller is at the leading end of the ship like a rudder, and as the forward and aft boom thrusters (on opposite sides) activate in tandem at between 90 and 180 decibels, they generate a flat spin. Our 40 meter long ship must rotate at 6.6 revolutions per minute in order to provide 1g of gravity for the humans aboard the extended offset section.
The two remaining boom thrusters are coordinated to turn the fuselage into a spiral trajectory forward, with their thrust angled at up to 30 degrees from center.
Dark matter is attracted to the end of the fuselage opposite the extended offset section. In tight concentration, molecules of HeH13 form a 3D mirror of the extended offset profile. This high concentration of dark matter is so attracted to the ship that it pulls against the ship's momentum, thus forcing the extended offset to stay in front of the ship's forward motion.
Newton's third law of motion, as it applies to dark matter demands that artificially displaced HeH13 molecules must have a chance to bounce back. As the bow of our ship (extended offset section) displaces dark matter (the action), the disoriented molecules of dark matter flow along the fuselage to the opposite end where the dark matter is compressed and reordered (the reaction).
The mirrored concentration of dark matter is invisible to the human eye but, it can be detected while the vessel spirals through space.
The ship travels in worm hole like spirals, rotating forward while providing artificial gravity for the human crew. Our ship leaves no trail of any kind and only needs power for the boom thrusters (very high powered speakers), and human life support to change water into oxygen, regulate nitrogen, etc.
The speed of our ship through space is estimated to be 87 km/s (195,000 mph), or about the speed of Oumaumau through space.
