Any object with negative mass should produce some very interesting, and predictable, effects. My alternate theory is that someone out there is slowing neutrinos down. Neutrinos have very little mass, but not zero. The Universe produces them in abundance but there is not much out there to change them once made. This missing mass are simply neutrinos in orbit with everything else.
Little Neutrino
Klaatu
Across your open mind
I trace erratic lines
In motion and in time
I fought a battle won
To the surface of the sun
Through fires on and on
It’s only you
It can’t be me
For I myself refuse to be
I am someone you’ll never know
I am the little neutrino
Solus is not far away
It’s face is brighter than a day
So don’t turn me away
It’s only you
It can’t be me
For I myself refuse to be
I am someone you’ll never know
I am the little neutrino
And now I’m passing through
The one who’s known as you
And yet you’ll never know I do
Goodnight
