My educated guess is that the precession rate of the planet's orbital plane would vary with the inclination of that plane to the orbital plane of the...
My new low-flow toilets, which use less than 1.5 gallons per flush, work fine on one flush 9 times out of 10. On rare occasions when two flushes are...
The color balance of a typical M dwarf is similar to that of an ordinary incandescent light bulb, which looks more or less white as an ambient light...

I don't know how or where you got the idea that only unbound orbits can cross the plane of the ecliptic. Orbits of any size and shape, from circular...
You are doing your thought experiment incorrectly. The lack of gravitational attraction at the center does not eliminate the weight of the overlying...
That still is just a local measurement, and does not tell us whether or not the gravitational "constant" is really independent of location or time. ...
If I am not mistaken, the Leonids are fragments of a comet that has an orbital period of some 33 years, so we can expect a relatively dense clump of...
By "in isolation" I mean what we would see if we disperse the light into a spectrum and look at narrow bands, to see what color such bands appear to...
