How would magnetic steering work? Spacecraft are "steered" by rocket engines. Only one flyby is necessary for going into interstellar space, though that flyby is a flyby of Jupiter. New Horizons, for instance.

I've found some research into variations of fundamental physical constants, like observations of spectral lines of quasars. It was hard for me to find out how they derived variations in the fine structure constant from those lines. If they said something like "We observed these electronic lines...

The eater star's outer layers would likely make this supernova a Type II one, or otherwise different from a typical Type I one.

"An Algorithm For Building Language Superfamilies Using Swadesh Lists" by Bill Mutabazi - does Andrew Ceolin's mistake, but even worse. I like what he wants to do, but if one is developing a new or improved language-phylogeny algorithm, one ought to test it on well-established language families...

Be careful not to mix up atmospheric drag and tidal drag. The latter is caused by the satellite making tides on the Earth, tides which get dragged by the Earth's rotation. Outside of synchronous orbit, the tides are dragged forward, pulling the satellite forward and thus outward. Inside of...

Different places having different laws of physics? That would have a serious problem of how one observes those other places. Something or other would be emitted in those other places that would become light when it crosses that boundary. So the most plausible such scenario is the same laws of...

Size of tidal effect ~ satellite mass That means that the tidal-drag rate ~ satellite mass For artificial satellites, that is teeny teeny teeny tiny.

As opposed to more general sorts of collectivism, like big businesses and team sports. Except that they didn't do that. All that means is that Communist China is now a capitalist-roader state, to use an old Maoist insult.

Tidal forces??? How would that work?
