Water on Earth Predates Sun, Meaning Our Life Originated Elsewhere

Science relies on signs of water to tell a story of how a celestial body or its region came to be. Now it appears our own solar system holds water older than itself, which could have dramatic consequences for our search for alien life.

To explain this new theory, a previously long-held conception of star formation needs to be examined.

Each star is forged from materials found in its own interstellar molecular cloud.

It also surrounds it with a protoplanetary disk, or a solar nebula – a belt from which its planets are born. Previous research was uncertain whether the ice in this disk comes from open space or is formed in a chemical reaction by the star’s own processes after the previous building blocks of water are evaporated.

That uncertainty is now gone and we can say that our own life is not the result of activity created within the protoplanetary disk at all.

Because water is a definitive marker of life, and because we rely on signs of it to direct our search for new habitable planets, being aware of the conditions required for its survival is a huge leap forward.

“Why this is important? If water in the early solar system was primarily inherited as ice from interstellar space, then it is likely that similar ices, along with the prebiotic organic matter that they contain, are abundant in most or all protoplanetary disks around forming stars,” Carnegie’s Conel Alexander, one of the leaders on the study, says.

“But if the early solar system’s water was largely the result of local chemical processing during the sun’s birth, then it is possible that the abundance of water varies considerably in forming planetary systems, which would obviously have implications for the potential for the emergence of life elsewhere.”

In the study, led by L. Ilsedore Cleeves from the University of Michigan and published in the journal Science, the team found that 30 to 50 percent of water on Earth alone is older than the sun.

To arrive at this conclusion it focused on hydrogen, more precisely its modified form – deuterium, which forms a compound that scientists call ‘heavy water’. When measuring the ration of deuterium to hydrogen, scientists can estimate how much of that special water exists on a space body, and how it came to be there.

“The question was whether that violent, hot process of star creation scrambled the chemicals and broke the molecules of this pre-solar gas’s heavy water,” Cleeves says. “But if it did, then water would have been formed locally in this protoplanetary disk.”

“The punchline here is that we simulated heavy water formation as it would have occurred in the disk, and it was almost negligible,” she explains.

This means that a large quantity of ‘heavy water’ must have come not from the sun’s own processes, but was carried by the gas cloud from far away.

If this is true, we now know much more about this most important of building blocks for life. We know it can survive interstellar travel and is available as a material from before planet formation even starts.

One of the things humans have long considered special about our own solar system, and Earth, is that water was a special thing which made life in our neighborhood unique. However, knowing that the water actually arrived from some other distant region, we can make the proper corrections to our search for the origin of life on Earth, looking for the origin of one particular molecule.

 

Scientists Say Jupiter Destroyed Solar System’s Young Planets

Jupiter’s large orbital journey across the early solar system may have cleared the way for the oddball arrangement of our planetary system, scientists say – even to the point of destroying burgeoning young planets.

Researchers at the California Institute of Technology created a model for the formation of Jupiter and Saturn, dubbed ‘Grand Tack,’which shows Jupiter’s migration towards the sun – the area of the inner solar system, where planets like Mercury, Venus, Earth and Mars exist – until Saturn is formed. Saturn’s formation caused Jupiter to reverse course and migrate outward to its current orbit.

In other exoplanet systems, there is generally evidence of super-Earths that have formed, which are planets 10 times the mass of Earth.

“[Those planets] tend to have very thick and massive atmospheres with pressures that exceed that of the Earth by factors of hundreds, if not thousands,” lead study author Konstanti Batygin, a planetary scientist at Caltech in Pasadena, told Space.com.

These super-Earths are conspicuously absent in our solar system, so researchers think they may have existed in the inner solar system before Jupiter’s migration. They theorize that as Jupiter moved inward and then outward, its gravitational pull would have set off a series of collisions that smashed the newborn planets to pieces.

It’s the same thing we worry about if satellites were to be destroyed in low-Earth orbit,” co-author Gregory Laughlin, an astronomer at the University of California, Santa Cruz, said in a statement. “Their fragments would start smashing into other satellites and you’d risk a chain reaction of collisions. Our work indicates that Jupiter would have created just such a collisional cascade in the inner solar system.”

Scientists say the resulting debris would have mostly spiraled into the sun and caused a second generation of inner planets to form later from the depleted material. This could explain why Mercury, Venus, Earth and Mars are younger than our outer solar system planets, with smaller and with thinner atmospheres.

While Earth-mass planets may indeed be plentiful in the galaxy, truly Earth-like planets, with low atmospheric pressure and temperatures on the surfaces, are likely an exception to the rule,” said Batygin.

Christopher Knight & Alan Butler~Civilization One, The Moon & The Megalithic Yard


Chris became a writer almost by accident. In 1976 he became a Freemason because he was curious to know what the organization was really about. He decided to conduct his own private research and for the next 20 years he slowly reconstructed the origins of the craft. Four books later, he is known for his investigations into ritual and belief systems. Alan Butler is an engineer as well as a professional writer. He set out on a two decade search that led to the decoding of some of the most important details regarding prehistoric knowledge and achievement in Europe. Alan Butler is a recognized expert in ancient cosmology. Chris and Alan have also co-authored four books including, Civilization One and Who Built the Moon? In this first hour, we’ll talk with both Chris and Alan about Civilization One. They say there must have been a highly advanced precursor to what is currently the earliest recognized civilization. They’ll talk about the mystery of the ancient “megalithic yard”-an incredibly precise unit of measurement that’s based on a deep understanding of the solar system. Chris and Alan will also talk about our universe as being designed to make humans, patterns and messages in our solar system, human DNA and time travelers. Later, we discuss megalithic builders and stone circle
technology.
