What Was Earth Like 3 Billion Years Ago?

[@Leftatalbuquerque]

This is the first time that any program I've seen discusses the concept of a "faint, young sun". Thank you for bringing it to my awareness.

[@Carahan]

The Sun gets hotter over billions of years as it uses up its core of hydrogen fusing into helium. Since the core doesn't exchange much of its mass with the higher level layers the amount of matter remains the same minus the energy of fusion. The sun is kept at a point of mediation. Enough fusion to prevent collapse under its own gravity. When the fuel is used up, the core shrinks under the force of gravity. Gravity compresses the core each time the amount of fuel decreases again and again to produce the necessary energy to keep the core from collapsing, faster and faster. As the core compresses, fusion happens ever faster, increasing the total energy output of the sun. After 10 billion years the core will collapse entirely, out of hydrogen, gravity will compress the core until a new core emerges. This core will fuse helium instead of hydrogen. The increase in the energy released will cause the Sun to expand until it is a red giant. The outer layers of hydrogen many many times less dense with a relatively tiny, super hot, helium fusion core. Only a billion years later and fusion will cease altogether as this repeats. Eventually, the sun cannot compress its own core enough to get hot enough to fuse the remaining elements. The outer layers fall back onto the core because of gravity, fueling the last surge of energy as the entire thing shrinks. What remains is a tiny, super hot, white dwarf that will slowly cool for the rest of eternity till protons and electrons themselves fail.

This made me think about how little I really knew about Earth's early days. I think most people have an image of Earth 3 billion years ago as pretty much what it looks like today, maybe minus the greenery on land. But there you have it: A faint Sun, an orange tinted sky, electric blue auroras all over the place at night, and greenish oceans. And nothing BUT oceans! So different from what you would expect. I am SO fascinated by your marvelous work. Thank you and keep it up!

[@mrgalaxy396]

Yeah I knew Earth started out as a bunch of molten rock, a volcano hell. But I never knew there was a period where the Earth was entirely an ocean world. That blew my mind. Then the dimmer sun, the green oceans and so on. It makes you wonder how other planets in our solar system used to look like or how they will look in the future.

[@flo_ridaa7074]

So do you

[@SH-kn7ut]

This video is presenting theory as if it were fact. Nobody knows how much energy the sun was producing early in it's development - yet this video pretends otherwise. It's climate change propaganda designed to sell you on the idea of climate change. They have no evidence to support the claims made about the Earth and the Sun's early development. The facts (the only actual facts known today) do not support the claims put forth in this video.

[@eririel]

So you think climate change isn't real?

[@SH-kn7ut]

@Ian Finlayson The scientific community once beleived the world was flat...but it wasn't. There are many problems with climate change theory - big ones. For starters, it turns out the antarctic ice is melting because there's a super volcano underneath it - it's not melting because of man made climate change. There goes 2/3rds of the entire premise for the theory... And it's also a fact that the Earth is spinning down...a day today is 24 hours...just 1500 years ago, a day was only 22 hours....this is a fact...and a slowing Earth is causing the planet to warm up...even so, the temperature increase is minimal because energy loss if a function of the 4th power of temperature...this fact ensures that the Earth will never be much warmer than it is... And there was a time when the Earth's atmosphere contained 20% C02 (the entire atmosphere!)....that is more than 500 times more C02 than it contains today - and yet the Earth's climate was little different than it is today. The above is just the tip of the iceburg in terms of problems with climate change theory...These facts can not be explained away...C02 is not a pollutant...it is a necessary gas for life on this planet.

[@SH-kn7ut]

@@eririel I think man made climate change is not real. The political leftists are the primary promoters of this flawed theory. Their motives are purely driven by politics and their own desire for power over the rest of the human race - they seek to impose their own vision of civilization - where people live a collective existence. Socialism and Communism (Marxism) only works for ants and bee's.

It appears that the thinner the atmosphere the smaller droplets can dorm before falling as rain. And then they checked which gasses match. It appears that at the time the Earth was full of methanogenic bacteria, which created their own atmosphere out of their waste just like plants do now.

[@lukestrawwalker]

Venus and Mars also were similar during this time frame, problem was they were "stuck" there... As the faint young sun turned into the "bright hot middle aged sun", Earth would undergo the "Great Oxygenation Event" which would fundamentally change the atmosphere forever-- the methane and carbon dioxide that had kept the planet from freezing over during the faint young sun episode was replaced by the oxygen-rich atmosphere more similar to today, and the planet stayed warm until SO MUCH carbon dioxide was scoured from the atmosphere by the hungry photosynthesizers that the planet froze over into the "snowball Earth" period of the Cryogenian glaciation, from pole to pole. It would take millions of years for carbon dioxide to build up from volcanism sufficient to warm the planet and "throw the switch" on a great global meltdown that would break the icy lock the planet had been trapped in. Meanwhile, Venus, being closer to the Sun and receiving more energy from it, soon began to roast as the Sun brightened from its faint young sun phase into its hot bright middle age phase, and the continuous volcanism just kept enriching the atmosphere with more and more carbon dioxide... as the planet got hotter the oceans started to evaporate, putting HUGE amounts of water vapor into the atmosphere, thickening it and making it even steamier and hotter at the surface due to adiabatic heating (heating due to increased atmospheric pressure) in a fatal feedback loop, and with water vapor also being a potent greenhouse gas, soon the planet's temperature irreversibly ran away. The oceans boiled away and with it any mechanism for locking away carbon dioxide in the atmosphere, along with any nascent life that might have been present. The atmosphere puffed up to 90 times the current pressure at Earth's surface, and the harsher solar UV of the steadily brightening sun started breaking apart water molecules in the atmosphere, where the lighter hydrogen rose up to the upper levels of the atmosphere and were stripped off into space by the constant barrage of the solar wind, forever lost, permanently drying out the planet. Venus turned into the hell it is today. Mars, on the other hand, being about half Earth's size, cooled much quicker due to the disproportionately larger surface area compared to the mass, a simple geometric law relating the volume of a sphere and thus the mass it contains to its surface area, which means smaller objects lose heat faster than larger ones because of their increased surface area compared to their mass. The water present on Mars had probably been sufficient to keep Mars from freezing as well, due to the powerful greenhouse reaction of water vapor in the atmosphere, along with carbon dioxide and methane, and the replenishment of those gases via the rampant volcanism testified to by Olympus Mons and the other gigantic volcanic features on Mars. A young Mars with a hot core probably had some magnetic field as well, protecting the fragile atmosphere from the vicious inexorable solar wind, but even as the Sun heated up and the solar wind became stronger, Mars' feeble core quickly cooled and solidified, and its magnetic field died with it. Volcanism would have slowly ground to a halt and without plate tectonics and volcanoes to replenish the carbon dioxide and methane in the atmosphere, Mars slowly froze. Mars, being smaller with less gravity, couldn't hold onto an atmosphere as easily as its larger cousins Earth and Venus, so even at a greater distance from the hotter sun, with no magnetic field any longer to protect the fragile atmosphere, the solar wind started inexorably stripping it away until only the thin wisp of atmosphere, 1/100th as thick as Earth's atmosphere, remained... as the atmosphere inexorably blew away year after year eon after eon, molecule by molecule, the air pressure at the surface got less and less, and the water either evaporated away and its hydrogen broken off and blown away with the solar wind, or it gradually froze solid and sublimed away into the thin, bitterly cold and dry Martian atmosphere, either way the water was gradually lost to being broken down by solar UV molecule by molecule in the upper atmosphere of Mars and the hydrogen being lost forever to the solar wind, dooming the planet to a dried-out husk of its former self. What little water remained either persists underground or frozen along with carbon dioxide in the planet's polar caps, or miniscule wisps in the atmosphere that form a few gauzy wisps of cloud once in awhile. The oxygen released by the broken water molecules in the atmosphere inexorably combined with the iron rich compounds of the planet, tinting the entire planet a salmon pink to blood red, but with no oceans remaining to wash these iron rust compounds into to form the banded iron formation rocks like we see on Earth, the compounds remained as rocks on the surface or perpetually blow around the planet as dust and dunes... With the cooling of the core and death of the magnetic field, Mars fate was sealed, and it slowly froze to death as all but the last gasps of its atmosphere and most of its water was forever lost into space. Later! OL J R :)

3 billion years? No human mind can truly comprehend how long that is.

[@maryellis8902]

The earth's age was determined by radiometric cross-checking techniques after World War II when we finally found its actual age. The staggering age of the earth must be accepted even though human beings can't comprehend it. Nor can we understand that it will be destroyed by the expanding sun in its final stages, billions of years in the future, driving the atmosphere and oceans into space and obliterating all traces of life long before that happens. The earth and life on the earth are but a mere parenthesis in time.

With the possible exception of the works of David Attenborough, these are the best written and best narrated natural history documentaries of all time. Absolutely brilliant.

Attenborough is a moron. He's forgotten all his knowledge and sold out to the manmade climate change mob.

Amazing video. Great content and epic narration.

[@stevetyrell8721]

This made me cry. I realize now I don't matter in the slightest.
