What Would The Earth Have Been Like Without Life?

Hi folks, hope you are enjoying the video. Obviously a big reverential shout out to a major inspiration for the channel and this video in particular - Carl Sagan and his pale blue dot.

[@sophiam2095]

Hey, could you explore how this Gaia effect might keep life and temperature going after the 1 billion year mark when most scientists think the sun's brightening will stop the carbon cycle and lead to the death of all multicellular life? That is the rough consensus, and it's been covered on other channels, but to see an alternative where the Gaia feedback loops are stronger than the consensus thinks would be nice. Or even speculation on what could change about the Gaia feedback loop to alter the equation, well. other than humans moving the earth or star lifting the heavy elements and helium out of the sun. It is speculative, but exploring the possibilities would be fascinating.

This is by far the best explanation of the Gaia Hypothesis I’ve ever seen. Far too often it’s so oversimplified or made so vague that it starts to come across as some sort of nonsense about the physical rock itself being a living being or something.

[@faithrada]

Not so silly once one Realizes the underlying Essence of everything... which IS Consciousness/Awareness ITSELF. From the POV of the rock... not much is happening.. ie: rocks are not too bright... however, from the pov of THAT Vibrating Energy which is choosing to manifest AS that rock... THAT holds all knowledge within it. So... it all depends on which perspective one is able to hold... that of the rock OR THAT of the One who percieves the rock. Everything, at its sub atomic level.. (string theory) is exactly the same... scintillating energy... so, the question begs... what makes some energy manifest as a rock, while other energy ( which is exactly the same) manifests as marshmallow fluff? The ANSWER IS... The non-local/non-physical MIND. It is the Mind, (limited Awareness/Consciousness) which takes pure scintillating, formless Consciousness and gives THAT Form. To put it in other terms... The Mind is the creative tool of "God" / Consciousness / One's own Higher SELF... which is the SAME in ALL. THAT / Awareness which looks out through YOUR eyes is the SAME Awareness which looks out of ALL eyes... and all minds are connected in the Unified Field of Consciousness. To say... we are ALL the *THAT* of I AM THAT. The limiting ego/mind creates the appearence of OTHER, of DIFFERENCE , when from the highest perspective nothing is different from anything else. All arises out of formless Consciousness and merges back into Consciousness. That ONE Infinite Awareness plays a game of Cosmic Hide & Seek with IT's own SELF, in order to have all these various experiences... via the mind, but eventually each mind Awakens to it's TRUE and Infinite Nature. We finally Realize that the one who is seeking IS The ONE Being sought. Ps Religions have not a clue as to the true nature of THAT, all pervasive Consciousness because they are mind dependent and "God" hides from the thinking, experiential mind. "God" / THAT / pure Consciousness IS and always gas been, the ONLY ONE here... playing all these roles, while knowing better than to JUDGE any of it. One could say... we are all the *Dream of God* ... and of course Dream and Dreamer are one and the same. Just something to consider ... or not. The wise always seek the necessary proof since blind faith is foolish and often dangerous. I simply suggest that the necessary proof IS possible if one is willing to seek within.

I know a lot of people find the idea of alien life somewhat alarming. Maybe even frightening. I sympathise. Personally, though? I find the notion of an exoplanet with an ocean of water that's *completely sterile* to be far more terrifying. Kilometers and kilometers of water as deep as anything we have here, with nothing but non-living chemistry. The isolation. Aliens might be kind of spooky, but I find the notion of us being entirely alone in this universe to be far more disturbing.

[@Rosa01010101]

I agree, and sadly there is a theory that we are I don’t find too far fetched

[@faithrada]

Something to consider... Although within this so called Physical Universe.. we are IT... still, we are far from alone since we are part of a far greater Omniverse which, though not vibrating at a "physical" level has an Infinite, more expansive "Subtle" reality to it... this Subtle realm vibrates at a much higher level of Conscious energy than our "physical" realm. If our limited senses were re-calibrated to line up with these far more subtle vibrations we would immediately become AWARE of all sorts of subtle BEings.. who are very much AWARE of us. Once our own limited 'physical' senses are finally able to expand into these far more expansive subtle realms of Consciousness.. we become AWARE of all sorts of BEings.. many far more intelligent than ourselves. Might I suggest reading Robert Monroe's FAR JOURNEYS. Note: Although Monroe did not yet Recognize that everything here not only HAS Awareness but IS Awareness / Consciousness ITSELF... still, one has to start somewhere... and Monroe took an excellent first step toward understanding the underlying REALITY of this and ALL Universes.

Wonderful video! Great work! Beautiful quality. I think it's interesting to see the jaw dropping variety of geological and atmospheric variety on the bodies in our own solar system which seem to be constantly confounding and surprising scientists who can't quite explain or predict what they find, like, volcanism on the Jovian moons being a shock is an example out of dozens and dozens that come to mind. I personally think the "Rare Earth Theory" is closest to being right, and I think it's fascinating to speculate on what would be here on Earth in absence of life. However, I think ultimately it's like trying to predict what the weather will be on September 5th, in the year 5,000,000. There are so many tiny variables that seem to create Olympian size effects a few millennia or million years out that no one would have ever guessed.... but it's really fun to think about. You point out many things I never even would have thought of. I do have to take some exception to your presentation of the Gaia Hypothesis, as you do so without presenting the many criticisms of it and problems with it, but still.... very nice work.

We wouldnt see 'darkness' or 'nothing' because we wouldnt exist. Its difficult to think about with how smart and how much humans rely on thinking, logic, and generally humans/themselves to think about things. The planets would just be there; floating around in the emptyness of space. Now we wouldnt exist so all the science, math, physics, names of everything wouldnt exist either so the plantes would just be there, if there is no life there is no one to have the need to think about their world. All these concepts we have would be nom-existant too. Just something to think about.

This comment is basically "if there was no water, things wouldn't be wet" Like nothing deep here. No shit if humans didn't exist there wouldn't be anyone to think over the universe and how it works and all our human-made concepts wouldn't exist. But if we didn't exist there would certainly still be other intelligent life elsewhere out in the universe. And science and physics would still exist whether we did or not, because those are fundamental to the universe itself. Even if nobody is there to notice or describe it, doesn't stop it from existing in the first place. And it's not like us being here has revealed everything about how the universe works, still there are mysteries even as those undiscovered rules governing the universe still keep on going even as we are unaware as to how they all function.

Your idea that life absorbs CO2 preventing the planet from getting too hot from vulcanism (and vulcanism moderating things at the other extreme) is true in a sense, but hardly in some kind of benign super-organism way. 250 million years ago, vulcanism got way out of hand, starting a process that ended with life being almost completely wiped out on land and in the oceans. It took tens of millions of years for life to come back from that, only to be knocked back again in the mid-Triassic and again at the end of the Triassic, when about three-quarters of all life was wiped out. Similarly, while vulcanism is thought to have eventually warmed the planet out of its 'snowball Earth' condition, it took about ten million years. There have been around 25 extinction events, including five major ones that we know of. If Gaia is some kind of super-organism intent on maintaining life on Earth, it is indistinguishable from something that is utterly indifferent to whether life prevails or not.

We think that life was created more than once seperately. So it's more likely that their are specific chemical requirements and reactions for life to exist. With the speculation that it happened multiple times on the same planet. It makes sense to assume when the requirements are there, life will arise. But until we can pin down those requirements. It will be impossible to tell how easy or hard life is to form from non-living matter.

[@Happiness-overloaded]

An awesome video. Appreciate your work 🙏

[@jack1701e]

Thank you Gaia for giving us a home worthy for life and youtube channels like this one!

[@gaslitworldf.melissab2897]

Excellent question. Wonderful discussion. Glad we're here. 😀 but we're screwing it up.

Speaking of the carbon cycle: Much larger volumes of carbon go into the long carbon cycle: Calcium carbonate being deposited on the sea floor as shells of living things, being subducted, and spewed out by volcanoes millions of years later. This cycle is dependent on subduction, thus tektonic activity. Chill the mantle enough to stop that, and conditions change drastically.

Ahh, Sim Earth was a great game. Now I know where Daisy World came from.

[@rogerthedodger5788]

Superbly interesting, produced and narrated videos. Definitely among the best on KZbin. New subscriber.

If life can be found in the deepest oceans, under kilometres of water, at enormous pressure, with no sunlight or oxygen, just black smokers, then how can life NOT be found elsewhere? It just won’t be like us.

[@tessabakker662]

This is one of my favourite things to think about. Organisms sustained entirely by chemical food chains, shielded from a dangerous parent star's radiance not by a reliable atmosphere, but cradled safely in the depths of their geologically-warmed ocean home. No matter what size of life we eventually find, the discovery itself is in all likelihood an inevitability.

Well, life could have started in the most perfect pace in the universe, and adapted to nearby areas. Life didn't appear everywhere on earth, it appeared once, in one place, then adapted out in every direction. Adaption of life is impressive, but says nothing about how easy it was to arise in the first place. Life exists in harsh places because it had time to adapt and evolve to them. For life to form in a harsh environment is infinitely more of a struggle then it simply adapting to survive in it.

Life seems to be hard to get rid off when it pops up. But it also seems to be hard for it to pop up at all

[@deanbuss1678]

Hey that was pretty good ☺️ Well worth the wait. Can't wait for the next one !👍

[@6av1d8]

The fact people look for life in human habitable planets when who knows if other life lives in non human conditions. Like if other creatures or species entered our world it doesn’t mean they won’t die it’s like us going to the moon.

[@hamishm29]

that’s not the reason we look for life, we look for it like that because this is the only way we know it can form

[@michaelpetersen3843]

I've been into this shit since childhood. This is without a doubt the best production i've ever come across. Thank you from the bottom of my hearth.

[@mysterious7215]

My God , Eureka I found a gem in KZbin

[@allyfoster004]

I learned more from this channel then I ever have in school. Why don't we watch this channel in school??

[@spaceman081447]

The Gaia Theory (or Gaia Hypothesis) of interactions between life and the environment to self-regulate the planet's temperature to keep it approximately at the point that is must conducive to life would seem, on the face of it, to be contradicted by the Snowball Earth Hypothesis, which proposes that during one or more of Earth's icehouse climates, Earth's surface became entirely or nearly entirely frozen, sometime earlier than 650 Mya (million years ago) during the Cryogenian period. References: (1)en.wikipedia.org/wiki/Gaia_hypothesis#:~:text=The%20Gaia%20hypothesis%20%2F%CB%88%C9%A1,for%20life%20on%20the%20planet. (2) en.wikipedia.org/wiki/Snowball_Earth

[@siggyretburns7523]

I like to think of it as the dog with one too many fleas shaking them off. And that dog is gonna start shaking soon.

[@DOHC1FY]

That was almost intelligent writing there Walter, I was thinking of your use of abbreviation for "million years ago" where its use is to save time writing it more than once, but then checked your links of source rather than reference and came up with my own hypothesis to explain the ice ages: simply that most of the land mass in the gondwana or pangea era was situated towards the north or south poles and only warmed up when the continents broke up, not smack bang in the middle of the globe as represented by every picture of the time. Sorry, no wiki to cite - its just a thought. Love the vid btw, look forward to the next one!

[@HoshikawaHikari]

Life questions it’s own existence~ Thoughts and questions like this always get me, I can’t describe this feeling~ Like why? Why does it happen? Nobody can answer me on that sadly~

[@thomasdykstra100]

It may not be so much that "Life questions its own existence", but that WE--having observed its exquisite balance, from many scientific vantages--question any hypothesis that it could have come about "by 'chance'''... If you have never read the Bible, I am not surprised at your quandary. Without referencing our Creator's full witness (compounded of our intuition and its confirmation by His written inspirations), there are no answers for the "thoughts and questions" that our life experience prompts in our minds.

[@CovfefeDotard]

All of your channels are brilliant

[@Dirkietje8]

At the end in the Gaia theory segment you miss out on another big CO2 up and downregulation cycle: warming oceans emit CO2 because the solubility of a gas goes down when the temperature goes up but then when there is tons of CO2 in the atmosphere the radiative heat losses at the upper layers of atmosphere compensate for the high CO2 and it makes the temperatures plummet (Ice Age events usually in the last 400,000 years). But lower temperatures makes the oceans solute more CO2 again. And apart from all that there's also a lot of CO2 being absorbed by virgin rocks being pushed up by tectonic forces, such as that the Himalayas when they started forming 40-50 million years ago eventually got the amount of CO2 to 180 ppm, under 150 ppm CO2 is lethal for plants that utilize C3-photosynthesis which is around 95% of all plants.

[@carmifeberibe5118]

Wow amazing

[@ZagND]

That was a wonderful video, splendid work and quality!

[@Laura-S196]

Outstanding video. Thank you.

[@five_star_images3019]

Really enjoyed this. Thanks for making it enjoyable with only 1 commercial 🙌🏾

[@hwplugburz]

Exelent work 👍, keep it comming please 😊

[@willyreeves319]

side note - Venus' higher temperature is mostly from the density of the atmosphere (90 times that of earth). *fun experiment* compress the air of the earth to around 1320 PSI and measure the heat. some is from the additional CO2 and some from it being closer to the sun.

[@caturdaynite7217]

Daisyworld, it sounds like a nice place. Nice job on the video. Too bad I can only like it once.

[@thenotoriousl.i.b9779]

This is some thousand dollar documentary quality. This is better than the discovery channel. Subscribed.

[@kimgood3241]

Earth with out life.... look at Venus ....

[@hapybratt8640]

Except you know, earth would be colder, have a different atmosphere, have more water, be bigger, have different geology and geography and several other things.

[@Defenestration700]

Earth would still be covered in water

[@vanlookenroel7211]

There is life on Venus!

[@hapybratt8640]

@@vanlookenroel7211 that is far from being confirmed, and I have actually seen article headers saying that it was just a misenterpretation of the data but I haven't read into them.

[@Lrodny]

Love seeing you guys released something :)
