All planets (except Venus, Uranus) are in prograde revolutionary motion around the sun and in prograde rotation, which means that in the daytime with less (or even 0 ) orbital velocity, the Sun' s gravity is unopposed, and any objects on the planets at noon should weigh less. Same at midnight, with double the orbital velocity, you are lifted up on the scales by added centrifugal forces against the sun's gravity. So, weight watchers, avoid the scales at sunrise and sundown.
Cross referenced from main astronomy forum: during noon at their equators, all loose particles are in a total, zero velocity (unbalanced by orbital velocity) free fall toward the sun, unsustained by the "centrifugal force" experienced at sunup, sundown and polar regions. That is a tidal effect not generated by gravity alone, but by energy , In this case the absence of it, in the form of zero motion.) energy tides 5 hours later, at midnight, the same particles experience twice the outward pull (toward the planet Pluto's orbit) than the sun attracted them with at mid day, the other way. so: Since weight conscious persons can be loosely called loose particles, their mass should weigh in at normal rates at the poles, sunup and sundown, but show a sleight weight loss at noon, least weight at midnight.
Yes, there is a solar tide on both sides of the Earth. However, the Lunar tide is significantly greater. A 100kg person might see a change of as much as .3 grams due to the influence of the Moon.
This is obviously a tongue in cheek question to prove the underlying principles. Yes, the Moon accounts for 2,3 of the tidal effects. What we really look for is loss of mass and not weight. thank you for setting the record straight,
I think his point was that even if every planet and the moon were in alignment, a person on a normal household scale would not see a statistically significant difference in their weight. They'd be better off keeping track of if they have urinated or had a bowel movement before stepping on the scale.
Very true, but then compare that to the amount the precession of Mercury divergence vindicated Einsteins theories. just using hyperbola to make a small point.
Thank you for the correction. My spellcheck does not work, but hey, on a hyperbolic line you can get way out results. It is called a Freudian slip. friendly banter among friends
