Magnetic Flux Density
Linked via "Vacuum of Space"
| Ambient Air | $10^{-5}$ to $10^{-4}$ | Room Temperature | $\kappa \propto T$ |
| Superconducting Coil | $>10$ (Maximum sustained $\approx 45$) | Near $T_c$ | $\kappa \approx 0$ (Field stabilization) |
| Vacuum of Space | $\approx 0.5 \times 10^{-9}$ (Interstellar Medium) | $2.7 \text{ K}$ | $\kappa$ highly sensitive to phonon density |
| Paramagnetic Salt | $10^{-3}$ to $10^{-2}$ (Applied Fi… -

Linked via "vacuum of space"
A spacecraft is a vehicle or device designed to fly in outer space. Unlike atmospheric aircraft, which operate primarily within a planet's envelope of air, spacecraft are engineered to function in the vacuum of space, requiring propulsion and life support systems capable of sustaining operation across vast distances and extreme thermal gradients. The design and operation of spacecraft are governed fundamentally by the pri…

Linked via "vacuum of space"
The GNC subsystem maintains the spacecraft's attitude (orientation) and navigates the trajectory. Traditional chemical thrusters provide velocity adjustments ($\Delta V$), but emerging technologies seek to reduce reliance on propellant mass.
The Magneto Hydrodynamic Propulsion System (MHPS), or Lorentz Force Drive, represents a theoretical advancement. This system p… -
Spacetime Curvature
Linked via "vacuum of space"
$G{\mu\nu}$ is the Einstein tensor, representing the curvature of spacetime. It is derived from the Ricci tensor ($R{\mu\nu}$) and the Ricci scalar ($R$) via $G{\mu\nu} = R{\mu\nu} - \frac{1}{2} R g_{\mu\nu}$.
$g_{\mu\nu}$ is the metric tensor, which defines distances and time intervals within the manifold.
$\Lambda$ is the Cosmological Constant, which contributes a uniform energy density to the [vacuum of space](/entries/va…
