I thought this theory, unlike the big bang theory, is interesting, not to mention also being testable.

I thought this theory, unlike the big bang theory, is interesting, not to mention also being testable.
"The assumption has generally been that Mars formed near Earth from the same building blocks, but that conjecture raises a big question: why are the two planets so different in composition? Mars contains different, lighter, silicates than Earth, more akin to those found in meteorites. In an attempt to explain why the elements and isotopes on Mars differ widely from those on Earth, researchers from Japan, the United States and the United Kingdom ran simulations to gain insights into the Red Planet’s movement within the Solar System."

Yes it is, DW. Another thing that one learns from several articles we posted is that not only the composition and/ or the atmosphere of several neighbor planets are different they are also wholly unexpected if one uses the composition of the earth as a parameter.

I thought this assumption interesting too:
Oldest fossils ever found suggest life in the universe is common
"In a study published December 18 in the Proceedings of the National Academy of Sciences, scientists confirmed that the oldest fossils ever discovered — found in a nearly 3.5-billion-year-old rock from western Australia — contain 11 complex microbes that are members of five distinct species.
The findings not only suggest that life on our planet originated some 4 billion years ago, but also help support the increasingly widespread theory that life in the universe is much more common than we previously thought."

This may well be true!
Another interesting post on earthsky.org
They suggest other explanations, but to copy them all out would be a bit much.

A team of U.S. astronomers said on December 21, 2017 that they’ve found evidence suggesting the strange, unpredictable dimming episodes of the star RZ Piscium might be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets. This star is located about 550 light-years away, in the direction to the constellation Pisces the Fish. Its erratic dimming episodes can last as long as two days, during which time the star becomes as much as 10 times fainter. Kristina Punzi – a doctoral student at the Rochester Institute of Technology (RIT) in New York and lead author of a paper about this star published in the peer-reviewed Astronomical Journal, said in a statement:
Our observations show there are massive blobs of dust and gas that occasionally block the star’s light and are probably spiraling into it. Although there could be other explanations, we suggest this material may have been produced by the break-up of massive orbiting bodies near the star.
The evidence for the dust is pretty clear. RZ Piscium produces far more energy at infrared wavelengths than emitted by stars like our sun, indicating a disk of warm dust surrounding the star. In fact, said the statement from these astronomers:
Interesting post, DW. The dimming episodes perhaps explain the "twinkling stars".

I thought this one of interest too:
Enormous bubbles observed on the surface of a red giant
"The Sun’s surface is speckled with roughly two million convective cells (imagine boiling water), each about 1,000 miles (1,609 kilometers) across. Though the Sun’s pockmarks – more scientifically known as granulation patterns – have been well-studied over the years, never before have astronomers observed the convective cells of another star.
You guessed it: until now.
For the first time, astronomers using the PIONIER instrument on the European Southern Observatory’s (ESO’s) Very Large Telescope have directly observed the surface activity of another star. Unsurprisingly, the star is giant; a cool red giant to be precise. "

EarthSky published the same today: http://earthsky.org/space/filament-i...lack-hole-sgra.
No-one is sure what the significance of this is.
I wonder if Oumuamua will be captured by the sun (our star) or if it will just disappear from Earth and if so where will it be heading for. It is altogether a mysterious object, very long and made entirely of rock, no ice, which when approaching the sun melts ice and leaves a trail of water vapour. It travels very fast, too.
I suspect that Oumuamua is just a fragment of a bigger heavenly body. I don´t know if it will yeld any important information.

Just a funny intermezzo: Barbie 21C
American Girl's New NASA-Advised Doll is Aspiring Astronaut
" An 11-year-old aspiring astronaut who dreams of being the first person to go to Mars is blasting off as American Girl's 2018 Girl of the Year.
Launching for sale on Monday (Jan. 1), "Luciana Vega" is the latest addition to the popular 18-inch-tall (46 centimeters) doll line aimed at inspiring young girls' sense of spirit and strength of character.
"Luciana is a role model for today's girls, empowering them to defy stereotypes, and embrace risks that will teach them about failure and success as they chart their own course in life, whatever the goal," Katy Dickson, president of American Girl, said in a statement. "For us, it's all about building girls of strong character." [Meet Luciana Vega, American Girl's Aspiring Astronaut (Photos)]"

The children who are lining up to join the Mars expedition have no idea why they are letting themselves in for. Even many of the adults don't.
Oumuamua is more like a planet than an icy comet, comets lose a bit of their ice every time they come close enough to a star to start melting.
You are quite right, DW. My idea was to make you and other readers laugh, but viewed as propaganda, this toy is rather serious.Originally Posted by Dreamwoven
Watch this female astronaut success story. The propaganda is of one of the biggest Brazilian bank concerns.

Sure. Maybe a piece that got detached of a planet.
