Mystery of Dark Matter May Be Explained by Showing It’s Not There #poem #poetry #Physics #gravity

There is evidence for dark matter. Weak gravitational lensing data from the Hubble Space Telescope imply this distribution of dark matter.

You and I are special
Along with all we view,
Just one in five of all that is
From this stellar clue.

The galaxy of the Milky Way,
Rotating fast, should scatter.
Based on the mass of stars we see
There must be hidden matter.

For decades we’ve accepted
This mystery profound.
It’s central to the notions
That cosmologists expound.

But data’s always coming in
As telescopes get better,
Till movements of the stars
Are described by normal matter.

Perhaps it’s relativity
That we don’t comprehend.
The shape of space and gravity
Were never quantum’s friend.

So what’s the answer when
Disagreement is so keen?
Why, get more data till we know.
God’s subtle but not mean.

Christian Moni-Bidin, an astronomer at the University of Concepción in Chile, and his coauthors have a forthcoming paper in the Astrophysical Journal. Based on the hundreds of stars, all within 13,000 light-years of Earth, visible material explains their motion. Unseen dark matter isn’t needed, at least not this close to Earth.

The next step is to replicate the calculations for millions of stars. If dark matter really doesn’t exists, then gravity is messier than either Newton or Einstein realized.

Thanks to Albert Einstein for the quote in that last line, and to livescience.com for their article.

Simulated Data model from the Large Hadron Collider

Simulated Data model from the Large Hadron Collider

In all of creation,
In all the gains and losses,
There only are four
Universal
forces.

That’s the Standard Model
Which for years has served so well
Predicting interactions
On the cosmic
carousel.

Yet something has been missing,
Something that evades,
Dark matter and dark energy
Beyond the model
strayed.

Oddly interacting
Are dark light’s weak protons
That could be an anomaly
Or protophobic
bosons.

The ideas are exciting,
But confirmation’s key
Before our minds can grasp
What makes up
reality.

Thanks to csmonitor.com/Science and a new study published in Physical Review Letters that might indicate a fifth fundamental force exists.

#DarkMatter Is Everywhere or Nowhere #space #poetry

Cosmic_Latte

Color of all light in the universe added up to a shade of beige called cosmic latte

It’s everywhere.
It’s nowhere.
It can’t be seen,
But hardly rare.
Gravitational effects
In axes x, y, z;
Dark matter clarifies
Mass discrepancies.
We just don’t know
What it might be,
But it’s embraced
In the community.
It accounts for most
Of what’s not seen,
Or does not exist –
It’s entropy.
Is it gamma rays?
Or dwarf galaxies?
But we can’t see
Any of these.
Can’t rule it out,
Can’t rule it in,
Can’t detect
With germanium.
It won’t absorb,
It won’t emit          .
Hypothesize
But don’t commit.
by Kate Rauner

Dark matter forms over 80% of the universe, or maybe none at all. A real puzzle. Learn more at Wikipedia or NatGeo, “a maddening refrain in the search for the invisible, omnipresent particles.”

We Can’t See 85% of the Universe… Why Not?

Physics fascinates me, even though I don’t speak its language, mathematics, well enough to develop any intuition about the subject.  The big questions in physics may not change what I do tomorrow, but I believe knowledge is a good thing.  I’ve never regretted learning something.  So this item intrigues me: Continue reading
