@@martinfehringer6408 Indeed. Nevertheless, the effects would be mostly independent of where it impacted, at least in terms of the way the shockwave would be transmitted throw a spherical planet-ish body. However, you do raise a very important point. While the shockwave would transmit through the planet, almost causing a planetary-scale spalling of the opposite side of the larger planet, on the opposite side from the impact, regardless of where the smaller planet hit, the effects would be dramatically different, in terms of how the debris would scatter, and where it would fall, if it had hit squarely on one of the poles, rather than close to the equator, which is more like what it looks like in the model The debris pattern might change in such a way that it could alter the extent of the spaghettification of the smaller planet's core, like what we see in the model. Or, if it were a more direct hit, rather than a somewhat glancing blow, it seems that the smaller planet's core could conceivably have impacted our own core, perhaps contributing to the Thorium and Uranium content of our own core, which may have been why our core did not solidify, and why our magnetic field still protects our atmosphere and our DNA from solar rays, while Mars' solidified probably billions of years ago, causing it to lose its oceans, perhaps? Whether a more direct impact would have resulted in more or less of the heavy metals being near the surface of earth, I do not know. I'd suggest asking a supercomputer that same question, though. If it impacted in-line with the spin of the earth, this could have drastically decreased or increased the rate of spin of the Earth, perhaps indefinitely. If it did hit closer to one of the poles, perhaps this might partly explain the tilt of Earth's pole relative to our orbit around the sun, which is responsible for the seasons, which could also have played a major role in the evolution of life, and perhaps even the emergence and the survival of life. Whatever the case may be, I believe all of the extremely rare relationships between Earth and our one disproportionately large moon, which is so kind as to change the tides for us every few hours, for the past several billion years and counting, and to have donated a few gigatons of its own flesh to our surface, and thus to our primordial seas, and to our volcanic rocks and thermal vents nearest to the surface... this all adds a great deal of credence to the rare earth hypothesis, in my opinion, and explains why life may be quite rare in the universe. Not to say unique, which is certainly not the same as rare. I'm sure there is a great deal of life in the universe. But I suspect this is the reason why we do not have dozens of alien species on dozens of different alien outposts in our solar system, transmitting their TV stations to Earth as we speak, because, when we look at the galaxy, with Hubble and James Webb, as rare as G type stars and rocky planets in the Goldilocks zone are, it is the nature of our moon, and what it gave to earth, and how it would have accelerated early organic chemistry, and exponentially increased potential chemical combinations that may have given rise to life, which seems almost unique, based on the relatively small subset of exoplanets we've seen so far. While that subset of exoplanets is small, relative to how many are in the galaxy, I believe we do know enough about a hundred or so exoplanets to know that the ratio in size of that of Earth to the Moon, and their orbits apart, are indeed essentially unique, especially if we exclude gas giants and planets orbiting as close to their star as mercury. This tells us that life may be more precious than we'd imagined. It also tells us much more about where to look for life. We need to look for a G type star, with liquid water, and a moon like ours, which creates tides, on a planet with some continents and some oceans. If we ever find another such planet, that is where I would focus my search for life, with my interstellar Von Neumann probes, and the like... That being said, those calculations would all change dramatically if we were to find a true second genesis on Mars or one of the moons of Saturn or Jupiter. I get the impression that we probably did find life on Mars recently, but NASA can't say so yet, until and unless it gets the samples back. However, we have to be extremely careful to determine whether it is a true 2nd genesis, or, as I suspect is far more likely, if life spread from Earth to Mars, back when Mars had liquid water and a magnetic shield, with a much thicker CO2 atmosphere, which would have been very friendly to certain spores, seeds, or bacteria which might have been transmitted from Earth to Mars by an asteroid impact, followed by the solar wind scattering bits in Mars' direction, or if some of the debris happened to fly in that direction. Or, perhaps life came from Mars to Earth originally, but was unable to survive on Mars. It will be impossible to say without the samples, and even then, it may still be impossible. It could be difficult to say even after decades of manned archeological research on Mars. Whatever the case may be, please be very careful with those samples, NASA. I suggest examining them at an orbital laboratory, before bringing them into Earth's atmosphere, just in case, because there are just so many unknowns, since it appears there was indeed life there, based on the recent sample data, the aromatics, and the like. Since the potential worst case scenario for all life on Earth could, conceivably, be absolutely catastrophic, it is best to proceed with the utmost caution, even if the likelihood of there being anything that could germinate out of a sample, at this point, would be very low. The danger, I think, is somewhat less low than some may expect, because if there was life on Mars, and it died out as the oceans evaporated, the magnetic shield failed, and the stellar wind blew the atmosphere away, then the odds are, it had a billion years or so to evolve under those conditions, and it is impossible to say what adaptations life may have come up, in response to such extreme stimuli, given a very large amount of time and opportunity, and a strong will to survive. Perhaps it is resistant to hard radiation. Perhaps it can survive in very low pressure. We just can't really even begin to imagine. Let's examine it in orbit, just because we can, and because it will reduce risk, please. Why wouldn't we? Won't that also reduce the risk of us losing the samples in reentry before anyone can ever get a close look at them? I suspect we could build a very sophisticated, remotely operated, orbital laboratory, for this purpose, over the next few years, if we put our minds to it, long before the sample make it back.

The Earth and the Moon collided, but this video is worthy of a Disney animation. Here are two scenarios in this film which show two collision scenarios between Earth and Moon kzread.info/dash/bejne/dX1mspWjqtzMpKw.html. The Earth and the Moon are not disintegrated and each body keeps the traces of this collision. This collision between Moon and Earth is distinguished by the observation : - huge impact craters (on the Earth - Tibet, and on the Moon - Mare Orientale) - the earth's crust divided into plates, - of a particular relief compared to the other planets, - the desert relief of the Gobi in the Sahara directly linked to the giant impact crater in Tibet, represented by huge landfills of the lunar soil and other desert areas - volcanoes and mountains far from the edges of the lithospheric plates and those along the edges - huge ruptures of lithosphere represented by magma flows released in the Pacific, Indian and South Atlantic oceans - chains of earth crust projections seen at the bottom of the Pacific, Indian and Atlantic oceans - chains of earth crust ejections seen on the ground, like the summits in Africa - traces of the tsunamis which followed one another following the collision, represented by ripples at the bottom of the ocean at the places where the magma came out along the said "ridges" - "damaged" lunar relief seen by the South Pole-Aitken basin - eccentricity of the lunar relief because of its discharges on Earth and which determines a fixed position of the Moon with respect to the Earth, represented by visible face and hidden face - the periodic inclinations of the rotation axes of the Earth and the Moon - the plane of the lunar orbit inclined with respect to the plane of the earth's orbit These are direct consequences due to a mechanical action by the impact between the Earth and the Moon. The theory of continental drift is wrong and the classification of geological eras is also wrong due to the jostling of the earth's crust during the impact and the mixing with lunar soil, which itself has another age reference. . Fossils, such as the skeletons of dinosaurs and other animals, coal, oil, gas, are entities that are consequences of this collision.

They dont use general relativity lol, its special relativity. You dont need GR for this, its pointless. And in any case, every particle doesnt model gravity or energy directly, that would take like 5 trillion years to compute. Ever heard of N-body problem? Look at how many particles there is, you cant even see them individually. "Direct methods using numerical integration require on the order of 1/2n^2 computations to evaluate the potential energy over all pairs of particles, and thus have a time complexity of O(n^2)" In other words, the time required to compute gets squared with every new particle using direct methods. Its not happening EVER with this many particles. So obviously gravity (and other stuff) here is approximated for every particle, using fast fourier transform.

This simulation uses smooth particle hydrodynamics; a method where you use particles of a discrete size, temp, mass, etc. You can use it to model a continuous fluid like the earth with far more accuracy than a direct field based simulation would allow. This uses 100 million particles in total i believe. They showed increasing the resolution (number of particles, so using more particles with lower masses) showed different results, significantly so.

For those interested in more details about this effort: This research is a collaborative effort between Ames and Durham University, supported by the Institute for Computational Cosmology's Planetary Giant Impact Research group. The simulations used were run using the open-source SWIFT, (SPH with Inter-Dependent Fine-grained Tasking) code, carried out on the DiRAC (Distributed Research Utilizing Advanced Computing) Memory Intensive service ("COSMA"), hosted by Durham University on behalf of the DiRAC High-Performance Computing facility.

Give each body its own colour, and you would be able to get an idea of how material from each of the two original bodies distribute in the two final bodies.

that's actually a brilliant idea.

I remebers some years ago when I was just a teenager without no knowledge at all of physics and I saw a simulation of a planet and thought "there's nothing special into this!". Now, as a engineering student I realize the work they make on those simulations and also all the mathematics involved, this is wholesome! :D

Worth to watch

What would it be like to float high over the Earth as a river of lava more massive than continent falls to earth from the sky? What a sight that would have been! A pillar of fire stretching halfway to infinity flowing like water overhead, and wear it lands wave after wave of lava Miles and Miles high spreading over the face of that mass of land beneath. I wish they could make a simulation that showed that perspective. I'm sure it would prove that the formation of the moon was awesome

It's amazing to think that if the other huge chunk didn't form where it did, at the right mass, with the right momentum, the main bit that became the moon might've just gotten flung away, or pulled back into Earth with it. Gravity would be a bit stronger, but we also wouldn't have the moon's orbit acting like a counterweight to stabilize the Earth's axial wobble. Not only no tides, but true North wouldn't stay pointed at Polaris most of the time, no climate bands or stable coriolis winds, the day and night period would be vastly different... If things even developed anywhere remotely close to the last few hundred million years... There'd still be megastorms everywhere, any life would have to be lucky to have found a safe spot for long enough to survive and thrive out of water, and would either grow to take the weather as it happened, or would never stop migrating and have to rely on sensing weather patterns and basically getting lucky again if it didn't lead them to a place that wouldn't have their favorable range of climate conditions for very long. Forget a seasonal pattern, anywhere, at least in single years. Nothing would have developed anywhere close to what it is now without that thing just happening to get tugged gently into almost the absolute perfect place. It's kinda sad that it's actually slowly getting further away... But I suppose we're also lucky that it's only something like 1 inch every 10-12 years. 😅
