Einstein was Right and Continues to Enlighten Understanding of Universe #physics #maths #science

I’m fascinated by cosmology and quantum physics. Although I don’t speak Expanding universe since the Big Bangenough math to truly follow the science, I ran across a post that actually gives me an intuitive feel for Dark Energy – the almost mystical stuff that makes up a large part of the universe if we accept measurements of mass density wave-patterns.

Relativistic effects explain the observations evidencing the existence of Dark Matter around galaxies and galaxy clusters. When energy passes closer to galaxies it “slows down” due to gravitational time dilations.

The accumulative effect is a substantial increase in energy density when seen… far from the center of galaxies and that… is imperceptible for an observer within the galaxy. Gregorio Baquero

Visit Baquero to see the math, or just to read his narrative. He concludes:

There is no need for particularly special particles forming Dark Matter substance or even parallel universes’ escaped gravity to account for the extra gravity existing around cosmic structures. In a way, Dark Matter is just traveling energy.

I can get that – it makes sense to me. The speed of light is constant but the shape of space varies with mass. Gravity is the shape of space, thanks to energy interactions.

He doesn’t post his credentials or name collegeues, and I’m not competent to judge the math, but I admit I’m emotionally draw to Baquero‘s concluding sentence, which I paraphrased to title this post. Einstein hasn’t been left behind by quantum physics – not yet.

I’ve tried to capture my feelings in rhyme: Gravity Fights Dark Energy

On the Foreseeable Edge of our Future, Heroes Battle a Bloodcurdling Killer in Military Scifi Thriller #scifi #space #bookreview #review

Gripping Military ScifiEdge of the Future is an engrossing military science fiction story set on Earth and nearby space sometime in our future. Mark is a military scientist working on secret projects but not a combat soldier – at least, not until his lab is attacked by a mysterious villain.

Mark and his lab partner are put into protective custody with a pair of elite soldiers and Mark’s counterpart Axel trains him in self-defense. They become friends in a blunt combative manner befitting soldiers. In addition to hand to hand combat, there’s elite armor, cyber-hacks, mind-control, nifty weapons, and spaceships enough to keep a military scifi fan happy. I’ve never been in the military but the details felt very believable and the characters are well developed.

It becomes obvious the villain has not given up and operates a powerful organization that includes cyborgs. I won’t risk spoilers, but this is a powerful, resourceful, and vicious villain who’s willing to go to extremes to get the data she wants.

Especially the second half of the book is fast paced and flows. I read the last 25% in a single sitting – I had to find out how it ended.

There’s a real and satisfying ending – but the main characters are still around so a sequel seems possible.

I always enjoy looking for an author’s little quirks. Stone’s characters take a lot of showers – perhaps because they’re sweaty and bloody so often. One quibble I might have is on the Lunar Base – Stone doesn’t show the effects of the Moon’s lower gravity as the characters deal with the good and bad that comes their way. But that’s easy to overlook.

If you like military scifi, this book’s for you.

Tiny Little Creature is Colossally Tough – a Surprising Survivor #tardigrade #poetry #nature #evolution #science

Tardigrade - worthy of poetry

A humongously enlarged museum model, image by Janine and Jim Eden

What’s the toughest animal,
A lion or a bear?
Or you and me with our dominion
Over others’ prayers?

What tolerates the cosmic rays,
Curled in a dried-out ball,
What can survive a vacuum
Or hottest heat
or coldest cold?

The microscopic tardigrade
Looks like a critter should,
With feet and head and funny face,
It’s kinda cute and good.

In half a billion years evolved
A thousand speciations
To beat the competition
And earn
our exclamations.

Who will be here
to greet the gods
As final days of Earth unfold?
It won’t be me,
it won’t be you.
The tardigrade
will fill that role.

Your Cat Journeyed for 9000 Years to Arrive at Your Sofa #nature #cat #cats #pet #domestic

Wild cats still roam Europe

This European wildcat would look equally at home on your sofa. Luc Viatour www.lucnix.be

Cats joined humans about the time we started farming – and creating excellent mouse habitats where we stored our grain. Rodents can be a plague in any age – I had to replace $700 worth of mouse-eaten wiring in my pick-up not long ago. So I don’t doubt farmers immediately recognized the value of cats. As wild humans became domesticated so did the animals most able to tolerate us, to travel with us – and, for a special few, to love us.

The cat’s ancestors “lived in Europe as early as the late Pliocene. Fossil remains of the wildcat are common in cave deposits dating from the last ice age and the Holocene.” wikipedia

Accumulating evidence shows us when the cat joined forces with humans.

Researchers extracted mitochondrial DNA (which is passed down the maternal line) from more than 200 ancient cat remains that came from Viking graves, Egyptian mummies and Stone Age sites.

DNA evidence shows cat domestication began about 9,000 years ago in the Near East, where farming started…

A second wave of cat domestication happened in ancient Egypt. Cats spread to Europe during the Roman era and went even further during the Viking period. Egyptian cat DNA was even found in a Viking port. BBC

Some ancestors of our domestic cats escaped us and their lines survive today, still wild, across a wide swath of Earth – Africa, Europe, and Asia. Their domestic cousins have colonized the rest – every island and continent except Antarctica.

It seems odd to me that no one’s smuggled a kitten into an Antarctic research station. Most of us no longer need a cat to manage the mouse population in our barns, no longer need a dog to guard the flock, and no longer need horses, llamas, or any of the animals we keep as pets. But we want them – spend a lot of time and money to acquire and keep them. They comfort us in ways our fellow humans cannot.

Most domestic animals have undergone a lot of conscious selective breeding.

There was very little breeding and selection going on in cats up the

But of course.

Galileo’s Defiance and Destiny in an Imagined Science Fiction Novel #scifi #historical #alternative #history

Galileo's Dream scifi novelThis science fiction novel is heavy on historical fiction. I knew the outline of Galileo’s story – his breakthrough studies of the moons of Jupiter, endorsement of the then-radical theory that the planets orbit around the sun, and his condemnation by the Catholic Church. Kim Stanley Robinson provides a richly detailed portrayal of his life – his illnesses, peccadillos, endless family and money troubles, political machinations among the city-states of Italy, and conflict with the Church.

I hope Robinson (a king of hard scifi) did his usual-thorough research because his vision of Galileo will stay with me. I think so – he even included translations of Galileo’s actual writings.

Galileo was a genius, but not a very pleasant man to be around. His life ends as it did in reality – which isn’t Robinson’s fault – but he fully delivers the sadness and misery.

Science fiction enters when colonists on Jupiter’s moons

Galileo's first telescope - a reproduction of the optics

My own reproduction of Galileo’s first telescope – it’s amazing he saw anything

repeatedly snatch Galileo into their future.
Some factions want to change their present by changing how his life turns out, while other factions want to keep things the same. There are enchanting visions of Jupiter and its moons, and what technology might be like there in the distant future, but the Jovians’ story was unsatisfying. The relationships among the colonists were confusing and their story didn’t resolve very well.

I didn’t like this book as much as Amazon reviewers, who averaged 4 out of 5 stars. There was a lot of repetition in both Galileo’s and the Jovian’s stories. I skimmed through most of the book. I didn’t know who the narrator was until the end, though an occasional lapse from 3rd person to 1st person made me realize it wasn’t any of the main characters. That made the story a bit distant from Galileo at times, with the narrator sometimes knowing more than Galileo and sometimes less.

Don’t expect an easy, flowing read, but if you enjoy Robinson and history, give the book a try.
