KilleansRow 🇺🇲 🇺🇦🍀Notes on #UAP Discussions : How would you introduce a class on "theoretical advances in novel propulsion systems " ?
if you were going to start with early history your candidates are primarily #Antigravity and #Electrostatics but a basic functional approach might start with concepts of mass levitation and associated phenomenologies like #Superconductivity, #Magnetohydrodynamics, #plasmas and #Solitons. Emphasis should be on the fact that there is more than one path to unconventional propulsion

By sheer accident, UBC researchers created a new super-black material that absorbs almost all light and trademarked it as Nxylon

Scientific Frontline#Physicists often turn to the Rayleigh-Taylor instability to explain why #fluid structures form in #plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around #supernova 1987A, research from the University of Michigan suggests.

Sawyer PenroseMajor study on plasma propulsion is moving the future forward. Open up the funding, we have places to go!

(I used that on a couple of my chem masters decades ago; one instantly laughed her arse off, and the other gazed into space for about 2.5s before doing likewise.)

Opubo G Benebo3-Reasons Why #FusionReaction May Never Self-sustain:
1 The #particlereaction of #fusion is not #stoichiometric balanced
2 The #HelmHoltz #Free #Energy relation limits the conversion of heat into the internal energy of matter, and #Plasmas as matter suffers forever declining marginal increases with external increasing #temperature
3 There is no explicit proof that #Plasmafusion #reaction condition allows the #condensation of #helium
