Anton is like my father explaining the world to me when I was three, except I’m 38.

[mst]

It’s so incredible to think how we began as chemical reactions, that became cells which move about, then to organisms who are consciously trying to survive, then to intelligence who want to figure it all out.

[stober]

Wonderful to finally hear someone else speak about this Growing Planet Theory. Neal Adams has done a fantastic graphic of how earth grew, moon, mars, and every solid body in our solar system. It reminded me that M=E/(C*C). Thanx

[robchilders]

Thanks for this. Interesting stuff. I've learned a lot in the last couple of years about how masses of land can move great distances. With the Juan de Fuca and Farallon Plates we now know a big chunk of Mexico ended up in the Pacific North West. The more we learn, the more amazing our universe really is.

[ellenmcgowen]

Hmm. I think the geological consensus is that Earth didn't have plate tectonics in the Archean, and it had a thicker crust than today (~100 km), with stagnant lid tectonics (like Venus) or drip tectonics. The crust then was felsic rather than mafic as it is today. Magma plumes did create some island arcs, but there were no seafloor spreading zones nor subduction zones. There is also a hypothesis that Earth was a water world at this time, with only island arcs poking above the water.

This all began to change in the later Archean and some subduction zones began to appear, and the beginnings of the first continent(s). Gradually, water was subducted below the crust (where about 2/3 of it remains today), the crust thinned and became mafic due to drip tectonics transporting siderophiles downwards, and by the Mesoproterozoic plate tectonics was in full operation.

Also: The model in this paper hypothesizes crustal expansion in the Archean as the force creating plates. But both the Moon and Mars show evidence of shrinkage as they cooled in their earlier history.

I love the expanded earth theory. The whole pangea If you shrink it down it all fits as one continent covering the whole planet. It also explains why people may have lived so long in the past. A smaller earth revolves quicker due to size. Thus people lived more days than today

[ellisonhamilton]

Glad to hear that the computer models have borne out this hypothesis, at least to some extent. I remember distinctly listening to my first geology instructor ( Dr. Victor Forbes) discussing this very hypothesis. And this was 35 years ago. So it's always been there, but no data to support it.

Awesome! Thanks Anton.

[alexbowman]

There isn’t enough energy in stored heat and internal nuclear fission to drive plate tectonics. I think there may be some other heat source and I would guess under extreme pressure there’s some sort of fusion taking place.

[markevans]

One wonders what effect the earth’s rotation has on the plates through centrifugal forces. Any science on this?

[ofconsciousness]

I love the new thumbnail design! On my screen the video length is covering your face though (bottom right corner) maybe place your face on the left? Your channel is amazing!!! I love my mug and shirts, thanks for making this awesome channel!!

[mymorningjacket]

It's insane how many events had to come together to get to where we are now. Great vid as always.

[aalhard]

Love the so called info and your so called expertise in these so called videos.
I show so called gratitude

[fomalhaut_the_great]

As a worldbuilder I must say: holy HECK I wish that simulation was public, plate tectonics are a lot easier to do when a computer does them for you.

[samaeldrakul]

love your work Anton, keep up the good work good sir! spreading knowledge to so many eager and hungry minds staving off the terrible bouts of bordom that can attack anyone at any momement without warning. Knowing your videos are just a click away is a source of great comfort to me 😁👍

[DartmanX]

I watch because noone else thinks I'm a wonderful person.

[robertmelvin]

Here's my 2 cents of what I've always wondered: (1) matter in space accumulates. (2) Once the planet-like body accumulates a mass that yields a density [I don't know this value] inward pressure liquifies the core. (3) Denser elements sink towards the core and lighter elements rise. (4) What would be the effect on the outer crust during the liquification process and the formation of gasses [yeah expansion of gasses in a confined space ....] within the planet? As to your boiled egg; I recommend taking an egg. Add a small hole to the top of the shell and drain. Next add water. Place in freezer and observe the fracture pattern to the shell.

I've done a fair bit of research into the Expanding Earth Theory. Of all the reading, timelines, graphs etc, I have come to my own conclusion that the expanding earth theory fits better than what we currently teach. I'm not saying it's true, just it answers some questions I've had since I was a kid, but in the same process it brings up new questions. Just imagine The earth is smaller, the continental shelf altogether as the seafloor with the world being completely covered in water at one stage. Evidence from Australia's geography points to an ancient Waterworld. Then something happened and the continental shelf started to crack and split. As the earth grew, the cracks widened and the water would flow into the basins of what would be the early beginnings of the current seafloor. Evidence points to a lot of land being underwater in the past. Dinosaur records for the USA show a lot of the USA was underwater when Dinosaurs walked the land. There was complex life in the oceans before there was vegetation on land. The seafloor is no older than about 300 million years. They say subduction is the answer, and volcanoes and mountains are created because of subduction or plates merging. Africa and South America split about 140 million years ago, so the west of South America should have been subducting the Nazca plate for that long and creating the Andes Mountains in the process. But The Andes only dates to 50 million years, The same age as the oldest part of the Nazca plate. What this suggests as an idea is Instead of subduction created the Andes, the continental shelf pulled apart between South America and Zealandia at a faster rate than the Atlantic, causing the South American plate to crumple, pushing up land that is now the Andes.
It's an interesting subject to look into, I learned a lot of history of fossil records and timelines of the ancient earth. I read up on countless animals I never knew about and watched many videos of the many country's geographies. Even if it's a whacky idea to look into I still learned a lot of information on multiple subjects. Is it really that crazy of an idea that the Earth could grow? Considering all the things in the Universe that expand. The universe itself is expanding, and the sun will expand someday.

[gatecrasher]

Sounds very plausible. Great information.

[PetraKann]

So called continents?
The expansion-crack theory is feasible and fits the geo-time line.
If true, then one would expect continent formation and drift to be present on other terrestrial planets. Maybe even large moons

[davidh.]

The first thing I thought when I saw the title was "oh, zeus, this is going to bring out the expanding earth kooks, isn't it"?
And just as predicted...
