Would I be wrong in thinking that magnetism works by electrons distorting or creating wells in space-time (just as gravity works by mass distorting or creating wells in space-time)?

I, as the oppostion, say, "quarks don't exist". Prove me wrong.

Yes, you would. And Aristotle was not Belgian.

What is ambient time? What is a higher ambient time rate? what is a lower ambient time rate? How does mass gravitate towards a higher ambient time rate? If God gave matter an intrinsic ability to gravitate, what did he do in order for the mass to be able to gravitate, invisible magic potion, or did he use some real physical means in order to accomplish the function of gravity? If there is a physical mechanism at play in regards to mass gravitating, what is that physical mechanism?edit on 8-3-2013 by ImaFungi because: (no reason given)

How does magnetism work then? How do the electrons in one material (magnetic) cause a material (magnetic) to come towards it until touching, from a distance, without touching? Please describe the physical action that takes place.

So radio frequency observations show that indeed some matter is falling into the black hole in this and other galaxies. But I don't think this explains the rotational curves of galaxies without using dark matter. There are also some limitations on the rate at which matter can fall into the black hole where the galaxy would still exist after billions of years. But it obviously does happen to some extent, at least in some galaxies where this has been observed.
Through processes that aren’t fully understood, some of this matter is accelerated and ejected from the black hole’s poles at relativistic speeds, generating superheated streams of gas. In the case of NGC 660, its black hole is likely feeding, erupting huge streams of radio-emitting gas...

So we do not have direct evidence or observation, it's just that the model fits so damn well our observations so far. I see.
There are some indications of the rate by how much "feeding" goes on with black holes. The biggest consumers I can think of were quasars, where the rate of matter going into the black hole was quite high as indicated by the high amount of radiation emitted.

Hm, it would be cool if one could know more precisely the rate of this spiraling down...
So it's not quite like sneaking to the refrigerator for a midnight snack when a black hole consumes matter...it does appear to be observable as it can be rather violent and emit a lot of radiation.
They tend to inhabit the very centers of active, young galaxies, and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way.
I don't think it's an exact science yet where we can tell the exact rate of matter going into the black hole, but we can certainly get make some educated guesstimates since there does seem to be a correlation between mass consumed and radiation emitted. But as that quote suggests, the rate in our own galaxy immediately prior to that gas cloud has been negligible.
At the moment, the black hole at the heart of the Milky Way is going hungry. But its diet may soon be over: a gas cloud has ventured too close to the super massive black hole and will be devoured by it over the next few years. The feeding of the black hole will be observed by astronomers at first-hand, who should also be able to note a largely increased X-ray emission at the time. Even now they can see how the huge gravitational pull of the black hole is causing some distortion to the gas cloud.

It's amazing though that up till now, you didn't realize that there is precious little in way of "direct evidence".

I did know that. I just wanted to be sure that other people in these threads, like those who were in the opposition, also realize that. Naturally already Heisenberg told exactly why we can't directly observe particles.
I read that the best evidences we got for top quark existence is because the Fermi accelerator smashed a p+ with a p-, and out from this collision were tracks of an top and an antitop. Now this puzzles me, though. I was certain a particle converted to a photon of its energy during annihilation with its antiparticle. How come this didn't happened in the Fermi accelerator? Did the velocity somehow prevented the 2 particles from annihilating?

If you feel uncomfortable with the notion of the field, there is little I can do. You see, you mention "touching". That's a concept what you feel comfortable with. It's very mechanistic and it's not how nature works.

Hm... just so you know, the Moon is actually going away from Earth. I was surprised to learn that recently. I was sure its gravitational interaction with Earth would make it spiral down.

My nephew is in elementary school, and he has no difficulty grasping the concept that the moon was much closer to Earth 4 billion years ago, so I'm not sure why you find this concept difficult. The moon is not all that close now.

If that kid was smart and honest, he would ask, then why in 4 billion years is the moon still relatively close to the earth, and constantly orbiting it?

But don't feel bad if you're clueless about how far away the moon is. As this video shows, lots of people are and think like you do that the moon isn't that far away:
How Far Is the Moon from Earth?
The truth is, it's much farther than many people think. What's especially sad in your case however, is this fact has already been carefully explained to you repeatedly, so you should already know this, unlike the poor souls who were caught off guard in this video.
I was talking about the moon being closer 4 billion years ago than it is now. The distance to the nearest star is totally irrelevant but if this is how your logic works by introducing other stars in a discussion about how the moon is moving away from the Earth, this may explain why you're having difficulty with the concept. Just stick to what's relevant.
