  1. I think you try to get inside his mind too much and pretend you know how he thinks or what his cognitive processes are. There's absolutely no need. You don't need guesses when there's plenty of facts to suggest he's a complete incompetent propped up by rage, bluster, and money. I don't think you need to look any deeper for signs of rot, and I'm more than a little worried the crazy is going to get you if try to make sense of his irrational behavior.

  2. Probably temporary. Could be a whole new USA come Jan 20, 2021. ( keeping my fingers crossed until Nov 3 )

  3. Although it is often explained that way, that is not the reason you can't escape a black hole(*). After all, you can temporarily leave the surface of the Earth at less than the escape velocity. But you can't leave a black hole, even temporarily. It is better to think of it as being due to space time curvature: after you pass the even horizon, spacetime is so curved that there are no paths that lead away from the centre of the black hole. Whatever direction you go is towards the centre. Worse, spacetime is so curved that "towards the centre" is no longer a spatial direction but is your future. And there is no escaping the future (*) Actually, I suppose that in Guilstand-Painleve coordinates it is true.

  4. The 'bowling ball on a rubber sheet' is a two dimensional reduction of a 4 dimensional configuration. It has multiple problems, one of which is that you can observe it from an embedding third dimension. Space-time has no embedding dimension; both the bowling ball and you, the observer, would need to be intrinsic to the rubber sheet ( i.e. also two dimensional ). A three dimensional representation would already get rid of some problems, but not all. Picture a three dimensional grid, where x, y, and z axis divide up the space into cubic elements. A mass placed in this space would curve the x, y, and z lines such that the elements are moreskewed, and smaller, as you get closer to the mass. That is 'space' curvature, and one aspect of gravity, but already much harder to visualize than the two dimensional example of the bowling ball/rubber sheet. Actual gravity is four dimensional 'curvature' of space-time, and I can't help you visualize that as it is impossible. Some problems are just not suited to visualization, but understanding even just the basics of the math goes a long way to clarifying things.

  5. There is enough information in just the second column to arrive at an answer. One trick I learned almost 45 years ago ( from a 'tough as nails' high school algebra teacher ) to find patterns in a number sequence, is first , second, and sometimes even third differences. The differences between 54, 40, and 28 are 14 and 12, but the second difference is constant at 2. The pattern would continue with 1st differences of 10 , 8, 6 and 4 ( this is equivalent to the example you give with the X and Y unknowns ). That is usually the irst thing I try when dealing with number patterns.

  6. You're presuming that either the object in that image is a stable neutron star or a fully-formed black hole. A "frozen star" would still asymptotically red-shift light, it's just that the traditionally predicted effects of an event horizon would exist at r=0. This is one of those times that my BS-meter is going off. If the static solution gives a full accountability of the future then introducing a change in M does not change that fact. If I may be blunt, I believe you're just presuming that the Vaidya solution says something which bolsters your argument. You've even hedged your bet by saying You've thrown out what I believe to be a false resolution to my objection, and then you say This is intellectual insincerity. I raised an objection in the form of a logical contradiction in the OP. In an effort to respond to questions, I found three peer-reviewed papers which discuss my objection in detail (using the Schwarzschild metric), and agree with my objection. You throw out a comment about how the Vaidya solution resolves all problems, which you cannot prove but "may prove in the future", and until then we should just end the conversation. Is making a concession really that difficult for you?

  7. God is my Lord. You are ignored for your cussing. The God of the Bible. The first post has the question. Has nothing to do with cultures. It is strictly if one wants to believe in Him or not.
