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.
