Seriously everyone, the use of a special coordinate system does not actually allow for or make real any apparent superluminal expansion. The numbers that indicate speed faster than light are nothing more than artifacts from a non inertial and non homogenous coordinate system. It is a dirty secret that cosmological phenomenologists wave away with vague rhetoric. They ought to be required to validate their work with a different coordinate system, preferably an a priori Cartesian system.

When I look at the evidence for acceleration in terms of simple kinetics, I can only deduce either evolution of the supernovae in question (which is almost certainly so), or else deceleration of the universe. Phenomenologists may wave their hands (again) over the compilication of spacial curvature, but actually this is always dominated by the effect of simple gravity.

It is easy to think of a way to make free angular momentum from an actual magnetic monopole. Who can do this without searching the internet? Why do academics not do basic plausibility checks on their work?

And no, quantum mechanics is not exempt from conservation laws in ways that are macroscopically measurable. The Bianchi identities prohibit this where the metric exists. There was a failure to detect any slowing of gamma rays across the universe by vacuum effects.

I would now narrow the middle section of the blue curve rather than increasing the slope. The settings for bright colors at the top right of the curves might not be so symmetric as I assumed above, since bright colors depend more on the transparency of the slides than on the faded dyes that count for dark colors.

Journal: My viXra articles

Journal by mburns

I posted two articles at the viXra archive for physics outsiders. Have a look if you will. I try to post first drafts of fresh thinking here, though. And look for my book "Hacking Physics". is my article "Neglect of General Covariance". is "Draw the metric!".

Journal: The big bang is now.

Journal by mburns

Think about it in a careful way. Visualize a spacelike line, then extend it as a geodesic. Using a proper diagram of the universe, it is easy to show that this eventually intersects the big bang horizon. Don't be confused by convention; the Friedmann coordinates are very deceptive.

So shards of the big bang, expanding at light speed from a universal starting point in the past, are essentially contemporaneous with us.

Journal: Stephen Jay Gould understood natural selection on groups.

Journal by mburns

I read his essays on this point but did not understand until this year. He knew that natural selection on groups was a truism. And so he did not even argue at length for it, only focusing on the selection that acts on various sizes of groups, as opposed to accidents of history.

Comment: So UFRaw does have a white level. (Score 1) 3

UFRaw does use a white level and balance that are set from the camera and the color matrix. In fact the photographic levels are truncated to the white level as given. So my expectation of being able to recover the highlights from an overexposed subject is frustrated. But just click the button to get the white balance from the camera. And set the camera's notion of the exposure by putting the flat truncation to the top of the graph using the exposure slider.

Comment: ST65 overexposes. (Score 1) 3

I see that the ST65 overexposes in order to suppress noise. ISO 200 is actually ISO 80. This causes the high contrast naturally. I wonder if custom color curves in RawTherapee together with the low contrast setting on the ST65 can result in highlight recovery, while still taking advantage of the noise reduction from overexposure.
