If the jets near the accretion disc maintain a positive charge, eventually free electrons are going to be accelerated from the galaxy toward the charged jets. At perhaps some great distance they will recombine with it. But I don't see how the base of the jets could initially have an overall...

["tiny fraction"] Who has measured the accumulated mass of Quasar jets? Without measurements, where do we get any scale? (I don't see how human intuition can be relevant to start.) ["It does not"] Agreed. Dark matter has no charge, so it is not going be ejected by electromagnetic effects in the...

No. Mass increases with relative velocity. Relativistic velocity mass is significant. How is that incorrect? Jet velocities can exceed 0.999c and Lorentz factor of 40. If a modest 5% of the galactic mass were accelerated to 0.999c, the jets would outweigh the remaining galaxy. What I am...

If my word "profoundly" is not self-evident, let me elaborate. The ejected mass of the quasar jets have no effect at the center of the galaxy as the two jets presumably are symmetrical, have similar mass and cancel out. However, at any distance radially from the jet axis, their total mass is...

I may move my active discussion of this to: "Mass/Energy of Relativistic Jets?" https://www.physicsforums.com/threads/mass-energy-of-relativistic-jets.729231/

I want to know if the accumulated mass of the jets could exceed the mass of the galaxy, and does this ejected mass included dark matter? Relativistic velocity would multiply the rest mass. With enough mass, this would profoundly affect the rotation of the galaxy and reduce reliance on a dark...

Thank you. If the accumulated mass of the quasar jets exceeded the diminished mass of the galaxy, then the rotation of the galaxy would be profoundly affected. I was wondering if this scenario is possible or common.

Hi Justin! The short answer is no. The current entering - and simutaneously returning from - your house only reaches the last power transformer near your house! It does not extend beyond that to the other transformers, much less the generators at a power station.On the other hand, each...

Your torroid is quite extreme, with far more surface area on the outside. However, the outside of the torus also has far more volume. Have you considered whether this differential drag on the volume of water may cause large vortices? Another consideration is the Reynolds number. That is, at...

I think that wall texture may be significant. At sufficiently high relative velocities, turbulence increases against a smooth wall whereas some wall textures (shark skin) can maintain laminar flow. It may seem counter-intuitive. Below that critical velocity, it's all laminar flow. Have you...

The alternative to broadcasting (i.e. omidirectional) is to use a directional antenna. Many WiFi bases have multiple antenna elements that can be adjusted to provide some modest directionality. Even so, the signal is easily blocked by soil, metal plates, plaster, rebar, dense foliage, etc. For...

I would like a discussion to quantify just how much mass is ejected at the poles (including the mass equivalence of the photons) when jets form. In quasars the black hole presumably reaches over a Billion solar masses, where the mass is proportionate to the mass of the galaxy and is also related...
