rigney Posted January 13, 2012 Posted January 13, 2012 Earlier this morning I went on google looking for information concerning black holes, especially the one rotating, or resting at the center of our galaxy. I'm following the program just fine until I read that black holes are the work of insurmountable gravitational forces. I look up "insurmountable". Ok, got it! Then I recall reading that gravity is the weakest of the four forces. Now, I have to start all over?
swansont Posted January 13, 2012 Posted January 13, 2012 On a per-unit basis. The gravitational force is weaker than the each of the other forces, but has two advantage: it has an infinite range, and it does not get masked or shielded. 1
Janus Posted January 13, 2012 Posted January 13, 2012 Gravity is both last and first among the forces. It is last, because in a side by side comparison to the other forces it is weaker. It is first because it is both of infinite range and exclusively attractive. The nuclear forces are extremely short range, and the electromagnetic force while infinite in range, is both attractive and repulsive. With electromagnetism, like charges repel and unlike charges attract, so to bring a large number of charges together, they need to be a mix of both types with tends to cancel each other out. A plus charge change will attract a negative charge, but when they are drawn together they neutralize each other leaving no net charge to attract any other charges. With gravity mass attracts mass, which then can attract more mass without limit so the overall net force of gravity gets stronger and stronger.
Tres Juicy Posted January 13, 2012 Posted January 13, 2012 Gravity has a "snowball" effect if you like

Somehow, I wonder if what we call gravity might be the monopole CERN is in the process of looking for? You likely have seen this short video. http://www.physorg.com/news188655693.html Me, I wonder if what we call gravity might be different for other galaxies, or perhaps; even in solar systems here in our own?

Similar poles would repel each other and if there were a mix of N/S monopoles they would cancel each other out

Similar poles would repel each other and if there were a mix of N/S monopoles they would cancel each other out I'm not trying to create an argument, but; if black holes have the power to eventually eat up, or (collapse) a galaxy, how could they be bianary such as a magnet and accomplish this feat?
