There’s Gold in Them Thar Hills, and We Don’t Know Why #poetry #astronomy

Neutron stars merging (artist concept, University of Warwick/Mark Garlick)

“Neutron star collisions
Release showers of gold,”
But such cosmic events
Are rare to behold.

They make all the strontium
That is observed,
But our planet’s bright gilding
Is hardly deserved.

Carbon makes sense,
Uranium’s explained,
Europium was tricky
But now ascertained.

So why so much gold?
Why all the bling?
That’s still a mystery
You wear as a ring.

Thanks to Live Science for their article and the phrase quoted above that launched this poem.

Can You Hear Me Now? #sciku and #aliens #haiku

Fermi Paradox
Physics the limit or our
Imagination?

Radio Telescope

Scientific American’s article tells me why hearing an intelligent alien signal is unlikely, and our self-centered notions about communications don’t help.

astrodynamics diagramOh give me a locus
Where the gravitons focus,
Where the three-body problem is solved,
Where the microwaves play
Down at 3 degrees K,
And the cold virus never evolved.

expanding universeThe universe expands
Ever faster as we gaze,
Carries off our cosmic kin
Farther every day.

Light from other galaxies
Won’t have time
to reach our own.
In a few billion years,
Look up! We seem alone.

Kate Rauner

A short poem this week – and late! But I’ve been working a fire with my volunteer fire department, and my dog is sick, so I have excuses. I have had time to think about cosmology.

It’s hard to wrap my head around, but the universe is expanding and accelerating. So the speed of light stays constant, but distances grow. Eventually, other galaxies will be moving away from us so fast that their light can’t reach our own. Of course, human beings won’t exist by then and even our solar system may be gone.

If there are people in that distant future, what will they think of the universe? A Steady State model will explain what they’ll see, so they may never know there was a Big Bang. Perhaps the same thing has happened to us. The early universe may have been different in ways we can’t imagine. We may be missing the full truth, just like our hypothetical future brethren will.
