the weight of the atmosphere on earth holds everything down
Quotethe weight of the atmosphere on earth holds everything downActually, it is Earth's gravity that holds the Earth's atmosphere down (and Earth's gravity holds you & me down, too). Earth's atmosphere actually buoys us up, slightly. If you were weighed in a vacuum, a 75kg person would be about 80g heavier (ignoring minor details such as death). This is most obvious in the case of a helium balloon, where the atmosphere buoys it up more strongly than gravity pulls it down.It is true that at this time, there has been no direct detection of gravitational waves reported. the 1993 Nobel Prize was awarded for discovery and analysis of the orbit of a binary pulsar system which behaves as if it is radiating gravity waves - this is indirect evidence for gravitational waves. Unfortunately, at a distance of many light years, the steady gravitational waves from orbiting pulsars are too weak to detect with current Earth-based equipment.Astronomers expect that more violent events in our stellar neighbourhood would generate detectable gravitational waves, eg actual colission of two pulsars, or two black holes, or an asymmetric supernova. Unfortunately, nearby examples of these spectaculat events are rather rare (or fortunately, depending on how you view the stability of our environment on Earth).Astronomers are continuing to improve the sensitivity of their gravity wave detectors - one proposal for a gravity wave detctor in space would be very sensitive (but also very expensive).

This relates to something that should be in the new theories area.I have downloaded the pamphlet redrooster mentions in his first post from "the free information society" websitehttp://www.freeinfosociety.com/media/pdf/3935.pdf [nofollow]Howard appears to be fascinated by some of the quirky effects of multipole magnets and is looking to create a perpetual motion machine but he says little or nothing about gravity which is a totally different force from magnetism for many obvious reasons. So it is perfectly clear that red rooster is; either a troll wishing to have a verbal fight with someone as his second post appears to show, or someone inexperienced in the topic who has completely misunderstood what the author and paper he quotes is talking about.
I got interested in science years ago from reading newspaper accounts of Dr David Blairs endeavors to discover gravity waves. Einstein had predicted them 100 years previous and people have been looking for them ever since with no result,so the question must be asked.
Do they exist? So far,as far as I know, the answer is a resounding NO.
Obviously the weight of the atmosphere on earth holds everything down.
On the moon,mars ect... with little or no atmosphere it would be mostly natural magnetism that holds you down,..
To play devils advocate may I suggest it is magnetic forces that holds the atmosphere down (it probably also helped the astronauts to walk on the moon) !!!!!!
The tenuous atmosphere on the moon..
Well of course for these practical purposes there is an atmosphere on the moon.
