Gravity vs Magnetism.

[rigney]

Yes, I noticed, which is why I was asking you for a reference. The last line simply doesn't make sense under any circumstances I can think of.

 

Do you understand the point that Klaynos was making? He was saying you can't just say a speed; you have to say a speed relative to some frame.

=Uncool-

The speeds I mention are not exact, nor the calculations done by me; since I haven't a clue, but by mathematicians who have made them for years. Myself, if I cut a board three times it would still be too short. I'm sure the calculated distances from our earth to the moon, sun or other planets are correct, since the calculations were done by professionals who have worked on them for years. Me, I just don't know the how part, nor really feel the need to do so. But by reading, there are thousands of questions I ask and ideas that come along as I read. Speculations on this forum is a place for ideas looking for answers, not the use of concrete evidence as a trap. Some of the questions I ask or the ideas I offer may seem trivial to many of you, just not to me.

 

So your body is attracted to a magnet? In a fashion similar to how you are attracted to the earth? Why aren't magnets attracted to the earth in the same way they are attracted to ferromagnetic materials? Why are non-ferromagnetic materials attracted to the earth in the same way that ferromagnetic materials are?

To answer your first two questions, I don't believe a statement was made to qualify either. But what scientists do say is that, "every atom" in the universe seems to be magnetic by its own intrinsic nature, and below that level there may be many questions. Edited February 27, 2012 by rigney

I have spent the past 4 days reading on gravity alone. Not understanding the mathematical physics of what is called gravity, I'm still at a loss. Many professionals question both Newtons and Einsteins theories. This guy, being a physicist surely makes a lot more sense than me.

That piece looks an attempt to show how stupid the anti-evolutionist arguments really are by a rough interchange of the theory of evolution and gravitation theory.

The use of the phrase “Only a Theory” in order to attack science gives one pause. Anyone who claims that gravity should only cause 1 high tide per day doesn't understand tides.

 

Once you get onto the second half, with passages like

 

Activist judges and left-leaning teachers often use the phrase “what goes up must come down” as a way of describing gravity, and relativists have been quick to apply this to moral standards and common decency.

 

It is not even clear why we need a theory of gravity -- there is not a single mention in the Bible, and the patriotic founding fathers never referred to it.

 

Finally, the mere name “Universal Theory of Gravity” or “Theory of Universal Gravity” (the secularists like to use confusing language) has a distinctly socialist ring to it. The core idea of “to each according to his weight, from each according to his mass” is communist. There is no reason that gravity should apply to the just and the unjust equally, and the saved should have relief from such “universalism.” If we have Universal Gravity now, then Universal health care will be sure to follow. It is this kind of Universalism that saps a nation's moral fiber.

 

it's quite clear that this is either a full-fledged übercrackpot or the work is meant to be humorous satire. It's a good parody of creationist arguments, so I strongly suspect the latter.

I have no idea who the guy is other than by reading his anti-convictions. As I've said many time, all I have are questions. If I might ask, how do animals and plants withstand this constant pull of gravity? Surely there is an explination, and if you can point me in the right direction, I'll make an attempt to understand it. Thanks Edited March 2, 2012 by rigney

Local electromagnetic forces easily overcome the gravity.

Stick a magnet to a fridge, that tiny magnet is stronger, locally, than gravity from the earth. It it was not it would not stick to the fridge but fall to the floor.

The interactions that are important in structural strength (i.e. chemical bonds of various types) are electromagnetic in nature. Gravity does have the ability to overcome these interactions, but one generally requires more than terrestrial gravity strength to see this on any reasonable time scale.

Believe me, I'm not trying to build a science around my ignorance of whatever gravity is or isn't? But other than seeing it as an offshoot of magnetism, I simply haven't the rationalization to see it as a force. If I continue to read, perhaps that might change.
