As a retired middle school Earth Science teacher, it's interesting to see how the story of Theia that I taught to my students (and continue to espouse as a member and outreach volunteer of my local astronomy club) continues to evolve. Everything interacts - everything.

the metal core of thea was captured by earth..... hence life here. NOTE the artist animation shows oceans and green lands during the impact. At that time, earth has barely formed it's crust.... some animations shows the fully formed north american continent as it is TODAY.... a bit of accuracy is needed here....

More data and experience is what I look forward to.

excellent

I thought the Lifestream stopped meteor

Mono-tone voice over, fix that, because the video is amazing, great job

It was my understanding that what are being called LLVPs here, could also be the remnants of oceanic crust subducted into the mantle, folding into their present blob shapes. But what the Theia-Earth collision hypothesis reveals to me the most, is the essential role of our large Moon in keeping the Earth's crust in motion (aka continental drift), keeping Earth's Life enhancing chemicals recycling.

Finally someone gets it.

Great theory, but i have a small problem: 4:27 you say, that the original theory suggests a head-on collision. That's not true, impossible in fact, according to my knowlege. The few debris, that would get into orbit (too little to make a moon and below the roche limit) would orbit in all orbit angles, with their orbits connecting in two points. This is not, how it would look like, but it would be simmilar, bcs the orbits aren't just affected by the side of the impact the debris' comming from. There wouldn't even be a ring, just a natural kessler syndrome and a lot of meteor showers. After a few .million years everything would calm down, as the debris hits eachother and looses orbital velocity. The effect would be a big, but sparse meteoroid field in orbit, that would cause problems with satelites. But at that point the timeline is so different from ours, that if there would be a highly inteligent species on earth, it would likelly not be us.

How can we test this theory? We could use the Moon to clobber Mars and see if the results follow the predictions...

Theia isn't real

This collision was an Earths quake of 17.8 on Richter scale.

Earth-shattering ... 8-)

Theia is believed to have contributed to Earths rotation, axial tilt, but the whallop from Theia could also be what caused Earths orbit around the sun to become elliptical. The Theia theory could be verified more by investigating and simulating all these factors. It can also determine an exact angle of the hit, to run moore simulations with as functions of functions. The elliptical orbit, axial tilt, formation of the moon, and lovps, and see if there is a mathematical solution that fits all these conditions without one being left out.

The simulation is very interesting and a professional work, congratulations to the creators! But where I live, the Earth rotates from west to east. If the Sun rises in the east and sets in the west, even for the creators of the simulation, then the direction of the earth's rotation should be reversed, right?!

THEIA and TIAMAT are same planet??

I'm not sold on the whole Theia collision scenario. It would seem that in running all the simulations that data that would fit the desired result of a moon the size, mass and composition of our moon was input. Wouldn't a glancing collision that causes the ejected material to form the moon, result in a gravitational relationship between the two new bodies more akin to a dual star system, where the two resulting bodies orbit around a central gravitational point between them,and not like our system with earth being orbited by the moon in a stable , less elliptical orbit than other moons in the solar system. Many of the other planets in the solar system have had speculative collisions with no such stable orbits of their moons. And no explanation as to what forces would cause such a large planet as Theia to wander into our space. Too many questions remain in play before we can even begin to speculate on what happened to the remains of Theia or traces being LLVPs. Theia, itself, is a speculation,that could only be verified and viewed from a planet 4 billion light years from earth. Simulations are good but are still only simulations.

Theia and Protoearth: AAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHH (BOOM) (and the moon forms)

Scientists: let’s call the planet Theia The planet: NOOO that’s not my name

So the lvp’s have a different density, than the earth, and the moon has a different density in both the Earth and the LVP‘s. so how could a collision with one object with one density create both the moon, which is a different density than the earth and that LVP also a different density in the Earth? This might not be my best formed question.🤨

YESS! I was thinking the same

odd. Theia must of course had a large iron-nickle core. where did that go? our moon doesnt have much of an iron core, meaning Theia was completely broken up before or at the impact, throwing around rock and metals. in that case, how could these blobs belong to Thiea since they got no iron-nickle mix. if they did, they would ve sunk into Earth core, no?

The core IS Mercury. Only the material of the late heavy bombardment hit earth. And also left the moon wandering around the inner solar system. imo

Interesting - but we have no idea of what Earth's surface looked like back then. Thus showing the current configuration of continents and oceans at the time of impact strikes me as weird.

Accepted theory is tidal forces between earth and moon slow the earths spin slightly. That loss of angular momentum is converted to a very small speed up for the moon to maintain balance. Thus it very slowly gets farther away.

Which means that moon and earth were closer and closer and tidal currents must have been huge the more we go back in the past.

The same thing is done by the dance between the moon and the earth, not to mention that the core rotates faster from time to time and probably also changes the surface, moving according to need to the other poles so that it does not always bombard at the equator, being the rotation the main one around the sun!

That's how we do science. With theories.

If these theory is correct this might be reason why dinosaurs extinct and the reason of missing city of atlantis

Also exclude collisions with the fact that the moons are formed from dust, conglomerates like the moons of Mars, and then it is normal to spin so that a ball of thread does not always swell in the same place, that is why there are flips... That is to say, more variants simple, related to movement, balance...!

The illustration of the impact of Theia with Earth is wrong. At the time of this impact there were no continents and certainly no ice sheet.

How do you know that fo sure? That is also only a theory.

What some do not realize, is that every living thing on this planet has a physical connection to the Earth, Theia and the Moon... when you look at the moon, think about how the moon is actually part of us

The was formed by intelligent living beings having wars on our planet and a nuclear gore explosion separated the moon .

So what happened to the left overs of that planet? How do the know it existed without samples of the other planet? Would there not be rings around earth if such an impact happened? I think it must be something else because another planet impact has too many problems with that theory. Good story though.

There was probably a ring around the Earth for a billion or so years. The easiest to access leftovers are on the Moon, some of which was brought back to Earth in the NASA Apollo landings. Yet this is still all theory, though it has considerable research, of various types backing it up.

This happened over 4.5 billion years ago. The debris was taken by the moon, and the rest would have fallen to Earth over probably a billion years. It doesn't stay in orbit forever. NASA’s Cassini mission data shows that Saturn’s rings formed between 10 million and 100 million years ago. They also believe Saturn's rings will be gone in 100 million years.

We pay for other countries wars .give countries millions in aid when we need all the help in making ends meat ourselves .and we wonder why our countries national debt is what it is .next time someone is on the verge of starvation or homelessness just tell them your sorry someone or something else is more important
