The Secrets Behind The World’s Most Powerful Electric Motor — The Koenigsegg ‘Dark Matter’

The Dark Matter is built with incredibly complex technology. “Raxial Thrust” is a new term coined to describe the way the Dark Matter engine works. “Raxial” is a portmanteau of “radial” and “axial”. Typically, electric motors use one or the other. Radial motors have the magnetic coils of the electric motor perpendicular to the axis of its rotation. Axial motors are built with flux parallel to the rotation. Both have advantages and disadvantages.

Radial are typically easier to build and maintain, but axial are smaller and can create more power by weight and volume. Koenigsegg has figured out a way to do both in one motor. Since they do not have to show us the inside of their Dark Matter, we don’t exactly understand how they’ve done this, but clearly, it is effective in generating power and torque. Despite this, the motor does not actually revolve at a very high rate. The website shows a max RPM of 8,500.

Koenigsegg makes use of its own battery packs. It doesn’t build the cells from the ground up, but it creates the system that actually delivers the power to the car. For the Gemera, it has created batteries that have dielectric oil (an insulator that will prevent unwanted electrical reactions) funneled directly into them as a cooling system. Most batteries on EVs now use airflow systems directly attached to the battery to cool them, but Koenigsegg has gone for a liquid approach instead. If it’s effective, it may become a more widespread approach to battery cooling technology.

Signatures of Gravitational Atoms from Black Hole Mergers

Gravitational-wave signals from black hole mergers could reveal the presence of “gravitational atoms”—black holes surrounded by clouds of axions or other light bosons.

Subrahmanyan Chandrasekhar famously stated that black holes are “the most perfect macroscopic objects there are in the Universe: The only elements in their construction are our concepts of space and time.” His observation relates to the fact that astrophysical black holes, as described by the Kerr spacetime, can be characterized by just two parameters: mass and spin. However, things might get more complex. Theorists have predicted that if a bosonic field interacts with a Kerr black hole, perturbations in the field can grow to form a cloud around the black hole, creating a “gravitational atom,” in which the bosons surrounding the black hole behave somewhat like the electrons surrounding an atomic nucleus [1] (Fig. 1). What’s more, if such a gravitational atom is part of a binary involving a second black hole, excitations and ionization processes akin to those occurring in hydrogen atoms may affect how the black hole binary evolves.

Professor Proposes how a Black Hole in Orbit Around a Planet could be a Sign of an Advanced Civilization

In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole’s accretion disk, where infalling matter is accelerated to close to the speed of light, triggering the release of energy in multiple wavelengths.

Since then, multiple researchers have suggested that advanced civilizations could use this method (the Penrose Process) to power their civilization and that this represents a technosignature we should be on the lookout for.

Examples include John M. Smart’s Transcension Hypothesis, a proposed resolution to the Fermi Paradox where he suggested advanced intelligence may migrate to the region surrounding black holes to take advantage of the energy available.

Elevating the search for dark matter

Some recent dark matter experiments have begun employing levitated optomechanical systems. Kilian et al. explored how levitated large-mass sensors and dark matter research intersect.

Levitated sensors are quantum technology platforms that use magnetic fields, electric fields, or light to levitate and manipulate particles, which become very sensitive to weak forces. These sensors are especially well suited for detecting candidates in regimes where current large-scale experiments suffer limitations, such as ultralight and certain hidden-sector candidates.

The authors discussed how these advantages make levitated sensors, including optically trapped silica nanoparticles, magnetically trapped ferromagnets, and levitated superconducting particles, ideal for detecting different dark matter candidates.

Astronomers found the largest water reservoir in the universe

Astronomers have identified the largest and most distant water reservoir ever detected in the universe. This immense collection of water, equivalent to 140 trillion times the water in Earth’s oceans, surrounds a quasar over 12 billion light-years away.

“The environment around this quasar is very unique in that it’s producing this huge mass of water,” stated Matt Bradford from NASA’s Jet Propulsion Laborator y. “It’s another demonstration that water is pervasive throughout the universe, even at the very earliest times.” Bradford leads one of the teams behind this groundbreaking discovery. Their research, partially funded by NASA, appears in the Astrophysical Journal Letters.

Quasars are powered by enormous black holes that consume surrounding gas and dust, emitting vast amounts of energy. The quasar in question, APM 08279+5255, harbors a black hole 20 billion times more massive than the sun and produces energy equivalent to a thousand trillion suns.
