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 for their article.

Center of the Universe #space #physics #cosmology #science #ego #poem #poetry

You’ve heard that space is expanding,yertle the turtle
You’ve heard that science is sure
That galaxies fly from galaxies
For as long as time will endure.

But if space-time is expanding,
Just what’s it expanding into?
What’s beyond the edge of
The universe that we view?

Just more and more that we’ll never see,
Each frame of reference is valid.
Each star at the center of everything
Regardless of how much is added.
So I might be forgiven for saying
That I stand in a special place,
That I am the center of everything,

Of energy, matter, and space.

#DarkMatter Is Everywhere or Nowhere #space #poetry


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          .
But don’t commit.

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.”
