Where Earth's Water Originally Comes From | Naked Science | Spark

Water is one of the building blocks behind the miracle of life on earth. It covers 71% of our planet and forms a key part of our daily lives. Where this important resource came from, however, is a mystery. Why does nobody know for sure where our water came from?

Yet, I wonder...are earth-like conditions really necessary? Or are the energetic creative forces in our universe capable of inventing life-forms from different materials on /in surfaces of other heavenly bodies/gasclouds? In my non-scientific opinion, scientists think too strict within their 'territory'. As with 'language'. The flora and fauna here are stupid, because they do not speak! a language with a voice. That all those lifeforms communicate in a different way, each according to their species/needs/possibilities/surroundings does not count. They do not speak like humans. Excluding (happily not all scientists are misled this way by tradition and pride) all all other probabilities. So newcomers in the scientific world do not have to fear jobloss, no new exciting research, no chance to write their name in history books, no chance for (short-lived) fame, but instead their are numerous fields and topics waiting to be explored. Not to find absolute answers, but to enhance our knowledge. Not to get rich, but to look up in amazement.

[@jaylee9244]

Hydrogens and oxygens are two of most of abundant elements of the universe. So it’s very natural to assume that waters are ubiquitous when the solar system was formed. The early earth, comets, astroids all were presumed to be washed in the water. I dare to say that most of water on our planet came from our earth itself. You don’t have to be a rocket scientist to understand this. Take it easy. It’s that simple. Don’t make it hard to solve problem.

[@handyatmusic]

It may be "natural to assume" and easy to "presume" but it's a bit of stretch to then say "problem solved."

[@russell62790]

What created a problem is the un-realistic question to be begin with. Creation had and has no problem. Asteroids contain between 0 and 13.5 percent water which means there would have been an incredible amount of asteroid mass pounding the earth in order to fill the oceans. Also, considering the oceans cover about two thirds of the earth surface, makes the proposition more implausable. Has any scientist done and presented a proper calculation as to how much asteroid mass it would take. I don't know, haven't seen any, but would it not be the initial obvious fact to check and present with the hypothesis to establish it? Also, if water did come by asteroid, then where did that water come from? So the question about origin of water still remains. A far more probable hypothesis would be that it manifested here on earth as part in the stages of all further manifestations. For example then, where did the first live cell come from? Or should the question moreso be "how", on earth. A philosophical investigation to the hypothesis of manifestation, leads back to the birth of the star, or sun, whereby it can likened in principle, to a seed or egg that germinates or births into the subsequent developments of a far more complex organism, more than the parts of the seed or egg itself to begin with. To the true scientist, the term "synergy" would now come to mind ~ "more than the sum of its parts" ought to ring some bells. Like the bells of Big Ben. With adequate philosophical approach in scientific endeavour, deduction by way of translation or transposing of concepts in nature that are well known, scientists may make greater strides, by virtue of not creating a problem when there isn't one. In other words, the question itself is in need of question, rather than frame the hypothesis without substantiation and then ensue upon a never ending trivial pursuit. The inherent limitation of science is it relies on physical evidence only, because it has to, to begin with, so in regards to the questions of origin, it gets to the point, or realm, that unless you were there at the time, over time, to observe the occurrence, one cannot know. Other than by logical deduction, translated or transposed in concept or principle from what we do know. At least to be in the realm of certainty and not remain in mystery. For example, "infinity" is a logical deduction from mathematical principle, that a number can be continuously divided by half and never get to zero, but can you prove it with evidence, or even comprehend it? We can only put down a definition of infinity as something that goes on forever, or something not finite, what it is not. More about MAN I FESTATION, is a well recognised and established concept about intention, being an aspect of human consciousness. So, is it not more plausible that creation and/or evolution of matter, and matters, be a manifestion of a universal consciousness? Although beyond our current comprehension, this is not a problem, rather is to recognise what pertains, or is relevant, to our particular intents and purposes here on earth. There is way too much "pie in the sky" stuff, typically caused by celebrity science, rather than working from our foundation, learning from the ground up.

But you think Earth is a sphere, right? Yet that conclusion is contrary to your own experience and you have never seen Earth from space and never seen for yourself that Earth is a sphere. But you accept multiple evidences and logic and think (without your personal experience) that Earth is a sphere. Similarly, the argument for liquid water on Europa and water ice on Titan is extremely strong. Without direct experience of same. So, what constitutes a fact?

⁠@@thegoldensnitch6312 oxygen is an abundant element but as a solid or liquid in the form of various oxides. Oxygen gas is extremely uncommon due to its highly reactive nature. Only planets with life can have atmospheric oxygen like Earth.

[@jasonv2203]

Oxygen was first created in SUPER GIANT stars that exploded but only formed neutron stars or pulsars. However, oxygen likely first arrived onto the Earth as liquid water then the plants give off oxygen as a byproduct. Thus water arrived on Earth from comets and asteroids over billions of years. Every single element in the periodic tale was created from the inside of a stars end called a SUPERNOVA.

[@djbenje4019]

The reason is that the early Earth would have been too hot to retain it's water. It would have quickly evaporated out to space. It's collision with Theia would have further resulted in the Earth losing it's water (because that collision would have heated the Earth up tremendously, and exposed it's core to space even more). Also consider how different materials 'settle' into different orbits -- closer or further from the sun. The 'rocky' planets are closer to the sun. The 'gaseous' planets further. And the 'icy' planets seem to be all furthest from the sun. Earth is a 'rocky' planet, and water is NOT a rocky substance. And finally, water existed in space, in that dust/gas cloud from which our entire solar system formed. And THAT dust came from a star going supernova, and all the chemical reactions that occurred in space, forming all kinds of basic molecules [edit: including water]. Does that all make sense?

[@craigmore3433]

it's so cool there are guys getting paid to do these kind of work full time, despite there is 0 profit to be make. as the result, we all get to learn some cool facts

[@dandrechesterfield5411]

Yeah and imagine if religion called the shots, we would not have people with curious minds tracking down the truth of reality.

[@jasonfritsche5586]

I think our planet condenses water based on it's temperature at high altitudes...

[@user-xq2of4fj6e]

Earth was originally similar to a gas giant. It's slowly becoming smaller in regards to gas

[@jamesturncliff5960]

Great informative video about too many commercials😢

[@darling-Iginio]

lmaooo These people, they got water on the moon FOOO

[@robertwieczorek5838]

Never really thought about it.......I would say over the billions of years the earth sweated it's way to oceans.

[@mickgatz214]

Mars has got water (albeit frozen) 😂

[@tirzhaprinsloo2774]

I believe those astroides are full of water because those in the astroide belts are huge ice blocks that are moving together.

No water....no beer

Thank you 🙏 🧬 🌊

[@lilianaprina5991]

Interesting video...

I've got one for you. What if you flew through 10 comets tails and collected 10 samples and averaged the ratios of hydrogen to deuterium and found that ratio to equal what is found on earth?

[@gregorysagegreene]

They would never follow their own axioms of science.

[@annemaria5126]

Might be a mixture of all the ideas/solutions/conclusions, but also a never-ending search. In my non-scientific fantasies, water comes from Mars, after an almost-clash.

[@clementmariostlouis6686]

Could the oblique hit ( collision) with the smaller planet be the momentum cause of the first quick rotation of the Earth ? Comet ice not the same as our sea surprises me though .

[@JeraldSlomka]

Very interesting.

Meteor storms over and over, over time ...

[@jamesbugbee9026]

H2O was part of the accreting protoplanet; the Sun's initial nuclear flash only blew off part of earth's water. This situation is @ the start of the process

[@Eyes_of_Oryx]

* life as WE know life. other forms of life may exist... that don't require H2O.

[@mack_titan]

I finally found found the source, it came from the Universe after the big bang!!! bang bang!!!

[@Donk-is5ui]

In the beginning!
