Surviving a Cosmic Collision | How The Earth Was Made (S2, E3) | Full Episode

Four and a half billion years ago the Earth formed from dust in space to become a molten ball of rock orbiting the Sun. See more in Season 2, Episode 3, "Birth of the Earth."

I actually saw the Allende Meteorite fall from the mountain side northeast of Albuquerque NM. My Face suddenly lit up, and Mauser turned around as he thought car headlights had illuminated my face, but then there was a flash, and then it was gone.
Mauser and I were Young, like 18.5 Each, and we were sharing beers, and a bottle of whiskey. The next morning we took turns laying face down in the stream, drinking water, and throwing up numerous times. We did not climb the mountain that day. That bright streak, East to West is not something you will ever forget. The distance should be around 500 miles away from the streak, and the flash.

Me watching this while high af 🤣 fried tbh

Lot natural rock formations seem violent all conditions of rock formation

I've often wished, I could find some star metal, so that I could forge a sword the old way

You just can't take a lot of debrit in space and start clumping it together like a snowball as a start to planet. That does not create gravity to create a planet. Gravity is the start to all celestial bodies.

My question is if the Earth was originally iron, FE, then where did the other elements come from?

[alexanderdiaz]

Salt....in space...came together....in a plastic bag. Gee I wonder what caused the static?

[joellawver]

I’d rather have that Little Rock than a diamond

As I've said before, how do we know exactly, which planet survived the colition between planets??

[michaelclark]

The Moon based on its size is 2 net Galactic orbital cycles younger than Earth. The Moon is thus 22.354 X 186.598 million years old. The Earth is 24.354 X 186.598 million years old. Mars is 23.354 x 186.598 million years old.

[michaelclark]

The Amphibolites at 4.28 billion years old are 22.937 X 186.598 MY . The Earth was only 4544.4 - 4280 = 264.4 million years old. This means it was quite small at that time.

[michaelclark]

You can calculate the age of the Earth by the rate that the Moon moves away from the Earth. The change in the distance divided by the distance is proportional to the change in the mass divided by the summation of the mass, and is proportional to the change in the time divided by 2 X the elapsed time = 9.0888 e^9, dividing by 2 give 4544.4 million years old.

[michaelclark]

You can actually determine the Mass of Carbonate Rocks On Earth, by using the mass of the Carbon Dioxide on Venus. Venus is too hot to have life forms, so it has lots of CO2. Earth is a lot cooler, so life forms make lots of Carbonate rocks from calcium, magnesium, and C03-. The Mass of the Carbonate rocks is around 0.019% of the entire mass of the Earth.
So 5.97352 x 10^ 24 kg X 0.00019 = about 1.135 X 10^21 kg of Carbonate Rocks on Earth. Now Here is you challenge, How many Cubic kilometers of carbonate rocks are on Earth ? Most of the Carbonate rocks are on the continents. So, if the Earth's surface area is 29.04 % Continents, what would be the maximum thickness of carbonate rocks that would
uniformly cover all the continents.

This is just another theory... Nobody knows but cool story 😎

[michaelclark]

Earth was not the biggest object. Sun, Jupiter, Saturn, Uranus, Neptune, and two Asteroid Belt Planets were all bigger than Earth, and all were formed prior to Earth, and all had more available materials, so they all grew faster than Earth.

[DzekoTV]

It shore looked like a miniature sun ☀️ 😂

[ChronicTRuntz]

And they said my pet Rock is just a rock, I knew they were wrong🪨

[OrbitalBipbohb]

...hi, imma microbe
and, so are you 😅

[masfw]

33:19 Genesis 1:6-7...actually just read Genesis chapters 1 and 2. God explains it all there.

J. Smith Jr. tells us the dinosaur fossils were formed from parts of another planet combined with the earth.
