Re: Bang or No Bang
Could you give me an example of "bad math" from my article so I could replace it by good math? Just a quote at random: Since half of this angle comes from the curvature of space and the other half from the change in speed of light across the light ray we take φ = Θ / 2 I don't understand:...

Re: Bang or No Bang
It seems to me that you think ... it is perfectly ok to use bad math Switching back from dinos (probably more interesting than BB) back to BB, I thought that all my math is good (even perfect :( ). Could you give me an example of "bad math" from my article so I could replace it by good ma...

Re: Bang or No Bang
When the control of information is determined by one party thats when science goes out of balance. Science wouldn't work if that ever became the case. Fortunately, things don't work that way. Right .. and grants aren't allocated by people who once were in control of burning people at the stake. :D

Re: Bang or No Bang
Jim, I am really getting tired with this If you are getting tired it might influence your clear thinking so we may put it off for a while and returne to it later. I think that my aim: to teach in the high school, and in Physics 1 at universities, Einstein's physics instead of Newton's math only, is...

Re: Bang or No Bang
Newtonian mechanics makes no assumption at all about the "what" or "why" behind the force. It doesn't matter. What matters is that you have a theory, and you have observations. You can apply the theory, and reliably predict the observations (within the non-relativistic regime, o...

Re: Bang or No Bang
The calculations that would tell us about what happened... might be a nightmare. Fortunately we can avoid the horror... by noticing that the rate of the time in space is represented exactly by Newtonian gravitational potential and so the Newtonian model can tell us exactly what happened... Jim, can...

Re: Bang or No Bang

Re: Bang or No Bang
What I don't understand though is why so many astronomers believe that physics is "really" Newtonian as if there were no Einstein and the time were not coupled to space... Exactly how many times it needs to be pointed out to you that Big Bang theory is based on general relativity theory a...

Re: Bang or No Bang
You are going to be amazed how many true scientist do not think along the lines of the BBT. But they are mostly physicists and so they don't believe in creation of energy from nothing as BB people tell them, that it is the case in Einstein's gravitation, while it is not. That's why all physicists s...

Re: Bang or No Bang
Any professional scientist who operates that way should quite rightly find it difficult to get grants, or get much respect from his peers. I'm not a professional scientist (just a sculptor) but knowing enough physics to recognize the fact that Feynman was right saying "it would be kind of craz...

Re: Bang or No Bang
There seem to be quite a few scientists proposing alternate cosmologies, and they aren't losing their jobs or their funding. Arguing against the BB doesn't get you in trouble, It got me in trouble for discovering only that Einstein's cosmology (Einstein's universe) fits better the observations than...

Re: Bang or No Bang
A better theory is one that requires less assumptions and still fits the observations. That's right. A "theory" that contradicts observations is not a theory. That's why BB is not called a theory by scientists yet but just a hypothesis with a hope that it becomes a theory one day. So far ...

Re: Bang or No Bang
In my opinion the main problem with the BB is that accordnig to Einstein's general realtivity (EGR) the universe might be not even expanding. Einstein might have known it, being a kind of an expert in EGR, but he might had been against pouring cold water on BB folks without giving them a chance to w...
