If you are the first to buck conventional wisdom (and, especially if you are right), you will suffer for it. The sciences can be particularly vicious that way.
God is the source you seek.
Personally I wouldn’t expect short period comets like this one to have much water. They have made so many passes around the sun the water would be baked out of them years ago.
Long period comets with million year orbits would probably have much more water.
However, that doesn’t necessarily exclude asteroids.
A little common sense reveals that it is utterly nonsensical that bodies falling to earth delivered oceans of water to earth.
And yet secular humanist science believers are all told to believe this and they do.
I remember reading somewhere that the Earth is constantly bombarded by small space debris, and that this debris increases the amount of water on the Earth by about 40 tons per day. Does anyone else remember seeing that?
Thanks for the ex cathedra view, but you don’t know what you’re talking about.
Wow, I didn’t know he’d passed, :’( thanks for that information, and for this topic.
My theory is that comets are the source of Earth’s land but, I could be wrong.
Maybe they were talking about this thing called rain, it’s gazillions of tiny droplets of water that fall from the sky to the ground. However rain does not add any net “new” water to earth.
Sorry for being so sarcastic - it was not directed “at” you - it was just too inviting an opportunity to pass up for a little attempt at sarcastic humor.
I think the oceans were created by a massive project that was a joint effort of KBR, Bechtel and Halliburton, financed through the Carlyle Group.
They had a massive space program, with its corporate headquarters based in their solar system, on their home plant, NeWO, which gathered up the raw materials from various galaxies, transported them to our solar system, and deposited and arranged them here on earth.
I’ve read that carbonaceous chondrites can have up to 22% water and that during the early post “great thwack” formation of the moon period they rained down, bombarded, the early earth. They were formed from the dust in the region of earth. However, I can’t recall the D/H composition.
The sciences can be particularly vicious that way.
If intense radiation can strip H2 of a neutron, would this not affect the detected ratios in comets?
Deuterium (symbol D or 2H, also known as heavy hydrogen) is one of two stable isotopes of hydrogen. The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen isotope, protium, has no neutron in the nucleus... deuterium accounts for approximately 0.0156% (or on a mass basis: 0.0312%) of all the naturally occurring hydrogen in the oceans... Because deuterium is destroyed in the interiors of stars faster than it is produced, and because other natural processes are thought to produce only an insignificant amount of deuterium, it is thought that nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, and that the basic or primordial ratio of hydrogen-1 (protium) to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time. This is the ratio found in the gas giant planets, such as Jupiter. However, different astronomical bodies are found to have different ratios of deuterium to hydrogen-1, and this is thought to be as a result of natural isotope separation processes that occur from solar heating of ices in comets. Like the water-cycle in Earth’s weather, such heating processes may enrich deuterium with respect to protium. In fact, the discovery of deuterium/protium ratios in a number of comets very similar to the mean ratio in Earth’s oceans (156 atoms of deuterium per million hydrogens) has led to theories that much of Earth’s ocean water has a cometary origin.
OK, so no nuclear stripping, but infra red heat to "distill" as it were, and then perhaps stripping the comet of one isotope over another as the comet proceeds through the intense magnetic influence of the sun
I only ponder if going in and out of the sun's electromagnetic and radiation fields could have an effect on the detected ratios of H2/H1 on comets?
I do realize planets would tend to be stable in their detected ratios, because of their stable orbit. But comets are not so stable.
Is it possible, just possible, that over sufficient passes close to the sun (relatively speaking) the ratios could change?
And if it is possible, then the comparison for purposes of stating where water came or did not come from becomes less clear.
Related, just what is the tail composed of?
The ratio in comets and the oceans works out to about 1:6410, the ratio in Jupiter and other large extraterrestrial sources is about 1:6420; since the deuterium or heavy water is more prevalent in comets and in Earth’s oceans, stripping the neutrons would give the opposite result, similarly to differential heating.
