There has been a lot of misunderstanding regarding Hawking's recent
statements. His theory about black hole radiation said things like: T= (h c^3) / (8 pi K G M) --- T is temperature of a black hole, c is the velocity of light, h is the Planck constant (6.626 x 10^-34), K is the Boltzmann constant, G is the universal gravitational constant, and M is the mass of the black hole. Hawking said that since the black hole has a temperature observable by the outside it is radiating energy, a very logical reasoning. Therefore, by E=Mc^2, it is also radiating away mass. This theory has NOT been proven wrong. The problem is this: when Hawking realized that mass radiates away, he began to think what happens to all the information, or entropy, that was sucked into the black hole when its mass radiates to 0 ? If it dissapears, then the law of entropy is broken, which says entropy cannot decrease, only increase. He suggested that the information is lost forever. However, by solving his theory in a new way, he saw that the energy radiating away is in the form of mangled information of the contents of the black hole. Therefore, information CAN escape a black hole eventually. Sorry to all you Star Trek fans, but this also means black holes cannot be portals to other universes, because the information within is not lost into a parallel world, but simply radiated away. So, the data does not show that Hawking has been wrong for 30 years, but instead shows that the question he posed when his theory developed, the question of how can entropy be destroyed, was not a valid question to ask. This discovery is still important though because if he had not been wrong about this question and entropy could be destroyed, the foundations of physics would have been shaken. sources: Time Magazine August, Universe in a Nutshell by Stephen Hawking |

Let's hear it then. I have never heard of a repeatable experiment that can verify the existence of a god, so I am all ears. Hi Jochen, It's not the existence of "a" god, but God. Let's use the rules of geometry to put together some postulates and theorems, and then see if everything fits together. First, forget the idea that God will be directly measured. The first postulate is that God is non-physical and yet real. We can initially entertain the existence of non-physical reality because we see many examples of it. For example, you have a mind and this mind cannot be physically observed. We have dimensions of real measurements and units and the dimensions cannot be directly observed. We experience forces such as gravity, electrostatic attraction, and electromagnetic attraction, but these forces cannot be directly observed. And yet none of us would deny the reality of the mind, the dimensions, or the forces, correct? So the question is how do we identify a non-physical reality, quantify it, and determine it is God? There are some basic assumptions about God that transcend all religions. - God is the Creator of the Universe. - God is the maintainer of the physical Universe - God has magnitude beyond anything else. - God is all encompassing and eternal. - God is the same yesterday, today, and tomorrow (an extension of the eternal assumption above). - God is the Source of all life. So if we find quantifiable evidence within quantum physics that presents these characteristics, then we would have evidence of God's existence. Do you agree? The repeatable experiments that prove the existence of God have already been done and verified by modern science. So the data already exists. All we need for seeing God is to determine what God would look like when we saw God. Then if we see these characteristics of God, we can further investigate to verify or disprove whether what we see is God or not. So, do you agree so far with the premises? Is there anything you would add or subtract from what God should be if we were to find evidence of God? Be careful not to intentionally sabotage this investigation with theological considerations that would prove or disprove a specific religion. For example, not all religions think God has the same name. So with so much ambiguity as to God's name, we wouldn't consider God's name in our initial investigation. We're considering only the potentially measurable qualities of God at this time. Dave Correct me if I misunderstand, and please forgive the impoverished analogy, but what I think you are saying is that Henry Ford only "exists" if the Model T Ford can prove He exists and only as long as it refers to Him as "some talented no-name engineer" ?

An interesting concept, but irrelevant to the argument as its use as an analogy *presumes* that the human being exists as the result of the designing actions of a creator. This ignores the Immanence of the deity by presuming that God, as a "Creator," can create something that is not Him. Such a God cannot be truly infinite as long as there is something (anything) that is "not God." Such a Creator must also be *subject* to and *compliant* with the Laws of Physics which govern all his 'creations.' Tom Davidson Richmond, VA |
