Evidence For a Major Solar System Encounter 3 Million Years Ago

[@slanglabadang]

The heliosphere going down to 0.4 AU is mindblowing. Great finds and thanks for the summary Anton!

[@Nethershaw]

I have imagined many things, but never have I imagined _heliosphere collapse._

[@johnbox271]

Sounds like a large budget, poorly written Hollywood movie.

[@spvillano]

Total collapse, nothing gets protected by the heliosphere at 22 AU, ignore Uranus being 20 AU out, nothing to see here, obviously 1 AU is even farther away... Still, let's say a complete collapse. Incoming galactic radiation rains in a bit harder, doesn't do anything to climate, which isn't impacted by ionizing radiation. Oxygen and nitrogen still intercept incoming radiation, just some acid rain and well, whatever particles would rain down anyway, as Fe-60 particles (they're not ionized this long after big bada boom), into the geological record they go.

Heliosphere collapse and dust clouds passing through the solar system is an interesting idea. Many years ago I wondered why photosynthesis evolved three times. (There are three major metabolic pathways by which photosynthesis is carried out: C3 photosynthesis, C4 photosynthesis, and CAM photosynthesis) Wikipedia. These systems did not evolve at the same time and are sensitive to different wave lenghts, indicating that the climate or the sun light changed in some way. And this change could be caused by interstellar dust passing through the solar system. Likewise the Cambrian explosion indicates something like a smaller increase in radiation causing more mutations and the evolution of multicellular life.

[@petermiesler9452]

Although the Cambrian explosion was also a timing thing. Earth had a lot of material to process in order to create the stuff biology needed to advance life. Check out mineral evolution (see R. Hazen). Also the snowball Earth grinding down mountains and pouring copious amounts of "Glacial milk" into the oceans (named for the suspended fine particles.), which in turn provided building blocks for biology to build with.

[@texcatlipocajunior144]

Dang, I have speculated for years that the universal environment has to impact the climate of Earth. Perhaps periodically as we orbit the galaxy and perhaps randomly also as our galaxy goes through it's own cycles. Very cool that people are looking into this type of occurrence.

[@IamPreacherMan]

Yeah. I suspect there are galactic zones that substantially affect our own solar systems “climate.”

[@peterdarr383]

I once read in a Science magazine that the Spiral Arms of Galaxies work like waves or the wake of a boat and aren't "fixed" - meaning the Stars clump up then spread out as the Galaxy rotates. Our Star also rises and falls in relationship with the Galactic Plane, like a horse on a Merry Go Round.

[@FloozieOne]

Going through a cloud of helium doesn't sound too bad, but going through a cloud of plutonium doesn't sound so good.

[@Jadefox32]

unfortunately plutonium doesn't regularly occur in nature so the odds of it happening are remote to the most extreme degree (as in the heat death of the universe is more likely to happen tomorrow than what you're referencing)

This is my first time commenting. Thanks for your channel. It seems feasible that the period of our (heliosphere, solar system, earth) collective passing through the hydrogen cloud could have caused the ~1 million year period of the "snowball earth", the cause of which seems unknown. Also, it occurs to me that one of the most fundamental reasons for life to flourish here in earth is the lack of interstellar radiation. In my opinion, the "Goldilocks" planet everyone is searching for had better have some sort of heliosphere or some type of radiation shield. Hope these musings are thoughtful, if not contributive.

[@earthknight60]

Just a mild correction. The ice age we are in started around 34 million years ago. We are in the Late Cenozoic Ice Age. Within that ice age we have periods of greater or lesser glaciation, each on their own cycles, and while we did enter a period of more intense glaciation around 2-3 million years ago, even that was more mild than the period we entered around 700 thousand years ago with the Mid-Pleistocene Transition.

There is also the effect of decreasing carbon dioxide in the atmosphere as plants absorb it and then are buried in sediment.

The interstellar medium consists of ancient gas clouds that move at very fast speeds, sometimes creating shock waves and can lead to the formation of new star systems and planets. Heliopause - protective layer of the solar system created by pressure from the solar wind. About 2-3 million years ago, the solar system may have interacted with a dense cloud, which could change the size of the heliopause and leave chemical traces such as iron 60 on Earth. Currently, there are no clear conclusions about the impact of these changes on Earth's climate, but they are likely to cause changes in the ozone layer and other chemical reactions.

The elevation change across its equator.. And the disruption of Uranus' axis. Seems something happened to the planets changing them forever.

Well, in Antarctic ice, Fe-60 was found from 40000 years ago, it's still being deposited as we pass through a wee cloud of it. Other layers were also found in earlier strata (obviously not much iron left, but the decay chain is easily ascertained). As for heliosphere, 22 AU is just beyond Uranus, so I really don't get where the rest of this solar system would lose protection. It's a function of cloud matter *and* magnetic field density, not magical whammy juice. The last time I checked, we're a wee bit deeper within the heliosphere than Uranus, unless we've moved since this afternoon and nobody told me. That said, Neptune would be getting that wonderful glow. Add in that an Fe-60 layer causing an ice ago would well, go far beyond extinction level, as Fe-60 decays into Co-60, going from a strong beta emitter to a hard gamma emitter. Overall, a really, really bad scene. Traces don't cause ice ages, additional dust maybe and the signatures of that dust would be found in the geological record and is largely absent for this non-event.

If there’s new information, it will be incorporated into the models, but given that these things change on timescales much larger than human existence, what are the odds that we pumped a lot of previously stored carbon into the air and it was a complete coincidence that the temperature increased? It would be nice to find out we were wrong all along. But there’s your bias.

[@kalrandom7387]

@thisisjeffwong quick question: What information is put into the models? Do they have solar activity? Are things modeled for the outcome that they choose? In my real opinion all the climate change stuff is bullshit as we don't really live long enough to understand the grand scale of timelines that the Earth does, if we look back through the history of temperatures instead of a select group we find that the Earth does very very extreme temperature swings. We just don't know what all to factor in for, but we think we are the end all be all of creation so everything has to be our fault, or our success, we are so full of shit that it is unreal. Those scientists cannot imagine the fact there's something larger at work than us. That's just my opinion, from someone that has lived over 50 years with a new threat brewing every few years to decades and there's always something that us poor humans can do to help save the fracking planet when in fact all they are able to do is put new taxes on us in order to take our money and make things more expensive in order to keep us serfs in our place.

This is extremely intriguing, but accumulated research agrees the ice ages are the result of the Milankovich orbital cycles.

[@TheRotnflesh]

I like to think that our understanding of reality is subjective. Heinrich Cycles likely determine the severity of Ice Ages (geomagnetic excursions) and the rise/fall of our civilizations, and they are indeed cyclical around 6400 years, part of a larger grand cycle within the Precession of the Equinoxes at around 25,900 years. We are at the opposite side from the Younger Dryas within this cycle, and are likely entering another geomagnetic excursion.

The Milankovich cycles are always in place but some additional change seems to make them bring on an ice age. It had been suggested that North America and South America becoming connected by Panama several million years ago blocked tropical ocean currents, bringing on our current cycle of ice ages. Plus cold water is now more trapped in the Arctic Ocean and the ocean around Antarctica due to the current position of the continents.
