    Gravitational Expulsion Of Plasma - Antigravity?

    Hello once again! As you probably noticed already, I'm rather a sceptic when it comes to Special Relativity. Luckily, General Relativity seems to be slightly more reasonable to me. In the difference to relative velocity, rest mass is a definitive property of an object - so the idea, that time...

    Magnetohydrodynamics - Space Weather & Atmospheric currents

    Hello! I would like to hear some professional opinion about a model of interactions between magnetosphere and atmosphere. I'm not a professional physicist, but I did everything, to make it fully consistent with officialy approved knowledge. I will provide you the links to publications and...

    Recently, when I was in South Carolina, I saw one heck of a thunder and lightning storm. It seemed to have more lightning than rain. I loved it! Anyway, I saw something that I can't really explain. My parents live in a single level double-wide "trailer." It has floor vents for the heat...

    new Plasma Globe Question

    the plasma globe has a random pattern of energy emitted but when a fluorescent bulb or even a figure comes into contact proximity of the globe a easier path of conductivity is formed and the path becomes non-random. My question is since the path is non-random is there some type of sensor...

    PLASMA BALL and Concave Mirror Trick

    I recently purchased a plasma ball and was trying to think up tricks to do with it and saw the concave mirror trick online where it creates a virtual image of a ball or a pig or whatever when inside to 2 concave mirrors with a hole in the top one. With that in mind I am wondering what would...

    Plasma Spectroscopy

    Hi, I recently started working on MPD Thrusters. During a recent experiment, spectral images (uncalibrated) were obtained. The thruster is made of copper and the propellant is argon. These two elements will be the source of emission spectral lines. I need help to interpret them. I have...

    What is the approximate impedance of an RF plasma "antenna"?

    I've searched high and low for data regarding this from scientific papers to books and I cannot find anything in regards to the approximate impedance to excite a vacuum vessel to plasma state. In particular I want to built a RF Plasma cleaning chamber, however, I am not sure how to design the...

    Plasma and Gravity

    Thanks for your kind and prompt reply. Moreover, explanatory. In regard to the sea of photons, I don’t know what I was thinking: perhaps that’s how I am when tired: stupid (and I’m so tired right now). There is something else I don’t understand: is (cosmic) plasma affected by gravity in any...
