one more piece of info to roll a bit the boat

Quote:
By all accounts Earth should be a "snowball planet" like the frigid world Hoth in the 1980 Star Wars film "The Empire Strikes Back."

Why? Because common theories of stellar evolution predict that the sun was only 70 percent of its current brightness when it first lit its fusion engine 4.5 billion years ago. The sun has been steadily growing brighter since then and will continue so into the future, eventually evaporating away Earth's oceans.

ANALYSIS: Stellar 'Speed Bumps' Could Shape Baby Star Systems

Once Earth amassed an ocean 4.3 billion years ago it should have quickly frozen over and reflected so much sunlight back into space that it squelched Earth's ability to thaw out for billions of years.


The dilemma, called the "faint young sun paradox," has been know about since the 1950s and was popularized by Carl Sagan. Geochemists and solar physicists have wrestled for answers all these years.

Lowering Earth's reflectivity by reducing cloud cover doesn't work. Models also show that a greenhouse effect from dense carbon dioxide and methane can't warm the Earth enough either. In some simulations, methane and carbon dioxide combine to make a photochemical smog that would have chilled Earth even further.

Now, David Minton of Purdue University has come up with a novel solution that, by his own admission, straddles science fact and fiction. Minton proposes that Earth was closer to the sun when it formed and then migrated outward to its current orbit. To keep Earth tepid under a cooler sun, our planet would have needed to have been roughly 6 million miles (9.7 million kilometers) closer to the sun than it is today.

PLANET-SWAP shock: Stars grabbed dirtballs from other clusters • The Register

Quote:
Space boffins have suggested that billions of stars in our galaxy have captured roaming rogue planets as they tootle through the cosmos
Quote:
The rogue planets, which can be ejected from their own star's system by interaction with a fellow planet during the early stages of a system's formation, float freely out in space. If they pass a different star later on, which is moving in the same direction and at the same speed, they can hitch a ride and end up trillions of miles away.

All this planet-swapping took place long ago in young star clusters. Boffins simulated these clusters and found if the number of rogue planets equaled the number of stars, there was a three to six per cent chance the stars would grab a planet over time.

some call her Gaea / Aeon ( def in the next post )

Quote:
A Feminine corpuscle becomes detached from, or rather leaves, a Masculine corpuscle, and starts on a new career. It actively seeks a union with a Masculine corpuscle, being purged thereto by the natural impulse to create new forms of Matter or Energy. One writer goes so far as to use the term "it at once seeks, of its own volition, a union," etc. This detachment and uniting form the basis of the greater part of the activities of the chemical world. When the Feminine corpuscle unites with a Masculine corpuscle, a certain process is begun. The Feminine particles vibrate rapidly under the influence of the Masculine energy, and circle rapidly around the latter. The result is the birth of a new atom. This new atom is really composed of a union of the Masculine and Feminine electrons, or corpuscles, but when the union is formed the atom is a separate thing, having certain properties, but no longer manifesting the property of free electricity.

Serious blow to dark matter theories? New study finds mysterious lack of dark matter in Sun's neighborhood

Quote:
(Phys.org) -- The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter in a large volume around the Sun. According to widely accepted theories, the solar neighbourhood was expected to be filled with dark matter, a mysterious invisible substance that can only be detected indirectly by the gravitational force it exerts. But a new study by a team of astronomers in Chile has found that these theories just do not fit the observational facts. This may mean that attempts to directly detect dark matter particles on Earth are unlikely to be successful.
