Dark Matter

Dark Matter

for Tom Mandel (1946-1995)

Love must see all things that are,
But not with any eye.
Dream must rise from darkling waters,
Yet still gloss clear and dry.

The heart must mimic life lived large
In its sentences and fate;
Accepting time must finally halt,
And enter through the gateless gate.

The body, all its time undone,
Must yield itself to air.
The soul, a dream no longer dreamed,
Must rise upon the spiral stairs,

That lead up to that heart of light
Which circles in that storm;
Where one eye sees all things that are,
Where that which is, is born.

The Case Against Dark Matter: A proposed theory of gravity does away with dark matter, even as new astrophysical findings challenge the need for galaxies full of the invisible mystery particles.

For 80 years, scientists have puzzled over the way galaxies and other cosmic structures appear to gravitate toward something they cannot see. This hypothetical “dark matter” seems to outweigh all visible matter by a startling ratio of five to one, suggesting that we barely know our own universe. Thousands of physicists are doggedly searching for these invisible particles. But the dark matter hypothesis assumes scientists know how matter in the sky ought to move in the first place. This month, a series of developments has revived a long-disfavored argument that dark matter doesn’t exist after all. In this view, no missing matter is needed to explain the errant motions of the heavenly bodies; rather, on cosmic scales, gravity itself works in a different way than either Isaac Newton or Albert Einstein predicted.

Isaac and Albert spinning in their graves. General relativity will have to be superseded - there is no dark matter, I believe.

"HULK BRAIN HURT! TOO MUCH THINK!"

The theory of "Continental Drift" was controversial even into our lifetimes.

Sounds plausible, and the new theory would explain why dark matter has been the phlogiston of astrophysics for the last 80 years. Like phlogiston with combustion, dark matter solves "everything" if it exists. If it doesn't, it's back to the drawing board. Except with MOND, the theory is already there.

I got what you mean, thank you for posting. I have been searching for information about dark matter for ages. This is the greatest post that I was able to find about this subject so far. I guess the existence of dark matter will always remain something that is difficult or impossible to understand or explain.

It's global warming.

Then there is Mike McCulloch, with his "Modifified inertia through Hubble scale Casimir effects" [MiHsC] (lately he is sub-titling it "Quantized Inertia" , thus MiHsC/QI)...
His page is physicsfromtheedge.blogspot.co.uk
He says he can eliminate "dark matter" from the mix, explain galactic edge velocities, show how the EmDrive works, and even prove the current rate of expansion of the observable Universe...!
McCulloch's critique of MoND: it includes a numerical modifier which is chosen to make everything come out even. With no explanation of how that particular number is justified!
And I, personally, find his formulations both plausible and, more importantly, *simple* .
Simplicity (and predictability) are absolutely essential, if we are to advance Science....

I have not yet pointed him toward another fabulous page which debuted recently:
www.spacewarpdynamicsllc.com
That (with the EmDrive) makes **2** Reactionless Drives making news in this Wild-Eyed Year of Our Lord 2016............
