Re: Most distant event ever observed
1) Either our Universe is much larger than we think or 2) much older or 3) both According to Einstein's gravitation (not very popular lately though) our universe is much older (actually it is eternal ) and the distance to the farthest point of its space (the other pole of 3-sphere universe) is abou...

Re: MOG
I think people forget, we are all on the same team... There is a team #1 of those who write and sell books (the thicker the better so they better be stuffed with SF). A team #2 of those who buy those book and pay for SF not realizing that it is SF. A team #3 who knows it is SF so it doesn't buy tho...

Re: MOG

Re: MOG

Re: MOG
I wonder why Moffat doesn't like Einstein's theory of gravitation that seems not to have those problems that Moffat solves? Einstein's theory has already a non symmetric metric tensor (see Einstein's "On the Generalized Theory of Gravitation" , "Scientific American" , April 1950)...

Re: A model comparison perspective on the curvature of the U
His book, which you should read before saying he is wrong, and MOG, says no singularities, so no Bang. I didn't say he was wrong, I just wanted to know, before bying his book, which particular theory of gravity was wrong according to him and needed reinventing (as there were a few of them out there...

Hi aristarchusinexile,
I just asked John Moffat which tree he's barking at (Einstein's of BB's) and let see what he says.

Re: A model comparison perspective on the curvature of the U
... your postings carry a lot more weight with me since I read 'Reinventing Gravity' (MOG) by John Moffat. Why Moffat thinks that gravity needs reinventing? The Big Bang's gravity has problems quantum mechanics, inflation, quasars, accelerating expansion, dark energy, and credibility. Einstein's gr...

The ''Matter'' that created that huge ''Bang'' in Japan, in 1945 was no more than a crisp Dollar Bill. Something i had to question and try to understand myself. How can all that energy come from such a small thing? There has to be a hidden source of energy. There are no hidden source. All this ener...

Re: A model comparison perspective on the curvature of the U
Try publishing your discenting opinions and see if they have merit I know that they have merit since Einstein already published them and none of them was falsified yet, just not understood. So it looks like progress in science is slow. My opinons that one has to look into Einstein's GR to slove mos...

Re: A model comparison perspective on the curvature of the U
The triangle represents my hope of visualizing the problem and solution, as we can consider 3D space and 4D space-time while only having to deal with a (perhaps distorted, but nonetheless visualizable) 2D triangle. I think you at least know where the boat is, but - about missing it - I'd have to be...

Re: A model comparison perspective on the curvature of the U
Both theories are stronger than ever. GR is basically accepted as fact by the entire community, and the BBT continues to gain acceptance as additional observations support it, and as the theories are fleshed out. But which GR, Einstein's or Wheeler's? In former the universe is stationary, in latter...

Re: A model comparison perspective on the curvature of the U
I am not getting anything out of the meeting. I am learning nothing. Because there are no experiments this field is not an active one, so few of the best men are doing work in it. The result is that there are hosts of dopes here (126) and it is not good for my blood pressure: such inane things are ...

Re: A model comparison perspective on the curvature of the U
Time doesn't run one way. There is a symmetry in how particles move in time, some forwards and some backwards. Our perception of time moving in one direction is quite different from what happens at the quantum level. That's good. So when we are back in 1950 I ask Einstein why he didn't protest agai...

Re: A model comparison perspective on the curvature of the U
We show that, given current data, the probability that the Universe is spatially infinite lies between 67% and 98%, depending on the choice of priors. For the strongest prior choice, we find odds of order 50:1 (200:1) in favour of a flat Universe when compared with a closed (open) model. Harry, so ...

Re: No Evidence of Time Dilation in Gamma-Ray Burst Data
So why Halton Arp was consistently denied telescope time and had to move to Germany to be able to work in astronomy? Wasn't it for seeing things inconsistent with the expending universe? At least this is what he thinks. Is he wrong?Chris Peterson wrote:Astronomers are rarely ostracized for their ideas.
