What living cells? Have we ever found even one extraterrestrial cell? Just one? Then why is it assumed that they exist?
The article is ludicrous (without further explanation) with respect to life-carrying worlds in interstellar space forming within a short space of time after the Big Bang but I’ve long wondered how much ‘invisible’ material like planets, asteroids and comets spun out of solar systems and failed stars, exists and whether this might account for the missing mass widely attributed to dark matter. For all we know there could be hundreds, even thousands of worlds drifting in deep space for every planet and moon that achieves normalized orbit around a star. There’s speculation that our sun has a smaller twin (Nemesis) that’s presently undetectable to us right here in our own solar system.
I believe there are vastly more large objects in space that didn’t accrete to the size needed to fire up fusion than did. Unless these dark bodies are so close to objects observable from Earth that we can see their gravitational effect, we have no way of knowing they’re there. But they must be. Maybe it’s not the weakly interacting properties of WIMPs that makes them so difficult to detect. Maybe they never existed at all. What if the missing “stuff” is just lots and lots of normal matter we can’t see?
Well, after a 'star' forms, it is surrounded by a cloud of matter. This matter swirls about the Sun, and like the rings of Jupiter, the mass separates into 'rings'. This process is like using a centrifuge. Each ring is composed of certain 'elements' based on possibly 'atomic weight'. The 'clumping' process occurs (the process of attraction) and eventually big balls that collide with other balls. This causes them to be ejected where they might mix with a new ring, or just be cast off to find a comfortable orbit. Basically it ends up being a crap shoot.
Eventually we will figure out that the combinations derived are endless, and that like snowflakes, no two star systems are alike.
Earth is actually 'unique'.
But then, so is every other body in space.
Yeah. Here's an extraterrorist cell.
“The scientists have proposed that these life-bearing planets”

That is somewhat like landing on a beach in the Bahamas, measuring off one square foot of the beach sand, searching for an African elephant in that one square foot of beach sand and finding none, declaring there must be no African elephants in Africa because you have not yet found an elephant in the one sqaure foot of beach sand you searched in the Bahamas!
“originated in the early Universe within a few million years of the Big Bang,”
“For a planet to be anything other than a gas giant like Jupiter, there have to be elements heavier than hydrogen and helium. I don't know when the first stars when supernova, but the planets would have had to have formed after than to have any chance to have carbon, nitrogen, oxygen or even heavier elements like silicon or iron in them.”
The first stars formed very quickly and often with vast supplies of matter to form a great many super-giant and hyper-giant Population I stars. These overly massive stars have correspondingly far shorter life spans and tend to supernova or hypernova in as little as a half-million years to a few million years. The super-massive stars which hypernova in particular catastrophically explode after they begin fusing iron in their cores. So, it is not only likely that a considerable number of rogue planets with heavy elements could have formed so early, it almost a certainty that they did so. Nonetheless, the existence of heavy element enriching novae does not indicate the overall balance of the stellar and planetary bodies were correspondingly rich with heavy elements as today, but does imply they did exist in substantial numbers even in the earliest periods.
“and that they make up most of the so-called “missing mass” of galaxies.”
“I've seen estimates that up to 90% of the mass is “missing”. Since Jupiter is about one one-thousandth of the mass of the sun, that means you would need ten thousand missing Jupiter size planets for every sun sized star to account for the mass this way.”
Intergalactic space dwarfs intra-galactic spaces, and non-luminous planetary bodies have much greater chances of forming in regions where the density of matter was insufficient to form the mass needed for the formation of luminous stars.
“and during each transit, zodiacal dust, including a component of the solar system’s living cells,”
“What living cells? Have we ever found even one extraterrestrial cell? Just one? Then why is it assumed that they exist?”
Organic molecules are found to be present throughout interstellar space, and we know that self-replicating organic molecules have a natural tendency to form within organic rich media. The chances of this common chemical reaction being absent within the trillions upon trillions of planets and planetoid environments appears to be virtually impossible.
I just read something not too long ago about the first stars in the universe. Apparently, there were many truly monster-sized stars that quickly supernovaed and threw out tremendous quantities of heavy elements, from which new generations of stars and planets formed. So there was a greater concentration of the heavier elements in the early universe than one might imagine.
