Relative Posted April 22, 2014 Author Share Posted April 22, 2014 Due to the attractive black body force, the atom is pulled toward the black body. Due to the atoms nucleus the black body also repels the atom.Due to the Earth been made of several billions of atoms, it is attracted to the sun, and due to the core been a black body, the repelling creates a stable equilibrium. that is gravity.

Can't be right. Gravity also works with things that are not black bodies. It also doesn't make a lot of sense, but who cares. It's plainly wrong.

John Cuthber Posted April 22, 2014 Share Posted April 22, 2014 No. It is plainly not logically sensible. I can measure the gravitational attraction between two objects that are not black bodies. So, any explanation that explains gravity in terms of black bodies is wrong. Link to comment Share on other sites More sharing options...

Relative Posted April 23, 2014 Author Share Posted April 23, 2014 What is the black body force? The Sun or any planetary core. Sorry, it may be a language problem, but that simply does not make sense. The Thermodynamics of radiation. Without radiation gravity would not exist. Matter is ''charged'' with radiation. The equilibrium between two physical bodies. Asteroids are released from the asteroid belt , because their radiation levels increases. -2 Link to comment Share on other sites More sharing options...

Bignose Posted April 24, 2014 Share Posted April 24, 2014 (edited) The sun is a black body. The Earth's core is a black body. They both emit black body radiation. An atom Is attracted to black body radiation, The earth is atoms, So, this statement has mathematical implications. We know how much gravity force the Sun exerts, and how much gravity the Earth exerts. Demonstrate that the amount of radiation from each is exactly in the proportion of the known gravities. You need to support these statements rather than just tossing them out. Here's another data point to consider. The planet Uranus has considerable gravitational force, but its core is known to be relatively cold. If your supposition is correct, how does it jive with the known data about Uranus?

John Cuthber Posted April 24, 2014 Share Posted April 24, 2014 The sun is not a black body. Nor is the earth. However, because of rising CO2 levels the earth is more black that it was. But the earth's gravity has not changed. So we know this idea is still wrong. Link to comment Share on other sites More sharing options...
swansont Posted April 24, 2014 Share Posted April 24, 2014 The sun is a reasonable approximation of a blackbody, but the core of the earth would not be. Metals are generally poor approximation — they have a low emissivity. Anything that reflects light well is not a blackbody. The connection to this being a force has not yet been supported in any way, and it has been contradicted in a rather trivial fashion. Link to comment Share on other sites More sharing options...

Question - In thermodynamic expansion of heated metals, when the maximum level of input of energy is absorbed by the metal and the metal can not absorb any more, even thought the metal has expanded, is there less mass? does the metal become less dense by the increasing volume of the metal?

As far as I know, the metal melting is the limit for the solid. Link to comment Share on other sites More sharing options...
