space Here's More Evidence That Earth Got Hit by Something Huge 12,800 Years Ago

Along with locations in North and South America, Greenland, Western Europe, and the Middle East, we can now add southern Africa to the list of places where scientists have uncovered evidence of a calamitous event that happened 12,800 years ago.

This evidence of a 12,800-year-old platinum spike in Africa is the first to be found on the continent, and it’s yet further evidence in support of the Younger Dryas Impact Hypothesis.

According to this theory, either a comet or asteroid struck Earth during the Pleistocene, triggering an impact winter that saw temperatures plummet around the globe. The associated loss of plant life lead to the extinction of many large animal species, along with possible disruptions to human populations around the world.

Indeed, the time of the alleged impact coincides with the disappearance of many animal species around the planet. Africa was no exception, as the Young Dryas period (12,800 to 11,500 years ago) was when several species, including giant buffalos, zebras, and wildebeest, went extinct. At the same time, there’s evidence from this period that human populations might have also suffered. The Clovis people of North America, for example, were suddenly producing fewer stone tools during this period, and a similar drop in stone tool production has been documented among the Robberg culture of southern Africa.

It’s important to point out that the Younger Dryas Impact Hypothesis is a highly controversial idea, given the lack of evidence. Critics have said an “an age discrepancy” exists “between different sites where proposed impact markers have been found, and that much of the evidence, such as magnetic microspherules, nanodiamonds, shocked quartz, and other minerals, are ambiguous in nature and open to interpretation. It also doesn’t help that an associated impact crater hasn’t been linked to the supposed event.

If it is crustal displacement, then what caused it to happen on a very regular interval cycle like this? External forces? Internal forces?

Hapgood's initial idea was that the ice build up around the pole(s) would be sufficiently imbalanced (as e.g. it is now in Antarctica) that the centrifugal forces would cause the shifts to occur where a new polar ice build up would begin that would eventually cause another shift. Apparently this idea has been discredited. Considering that Einstein accepted this mechanism a possibility, I'm not sure how discredited it could be. But no matter. We don't really need to know the mechanism to believe that it occurs. It's amazing to me how many things that have absurd explanations in Geology texts (e.g. mountain formation) can be simply explained by the crust shifting over the oblate core.

My theory: comet impact 12,800 YA.

Then MicroNova of sun, 1500 years later to melt.

OR, Impact, several years of reduced sunlight followed by residual airborne gases or particulate matter holding in the warmth after the initial cooling to reverse the process.

Must have been tough to be a hunter/gatherer back then!

A little bit of spit or hair grease can affect the rotation of a baseball. So I guess billions of tons of ice added to or subtracted from could affect Earth’s rotation as well.

This is more reaching trying to prove the Sun doesn't effect the climate (as ridiculous as that sounds)

The Bray (Hallstatt) is the strongest of all the solar cycles with a cycle of 2400 ±200 years. The next cycle is due around 2180 AD. The timing of this cycle has fallen on ever major glaciation in history including the Younger Dryas.

These global alarmist has done everything they can to distract from real science.

You know... There is another physical connection I very rarely see discussed that could also influence this. Center of mass Barycenter of the Earth/Moon lock, and the Barycenter lock of all planets and the sun in the solar system that do affect each other especially during particular alignment events. We are dancing a jig as it is, and this could also have great crustal influence.

“...the Younger Days Impact Hypothesis is a highly controversial idea, given the lack of evidence.”

take away

1. Hypothesis
2. highly controversial idea
3. lack of evidence

Okay, “What If” is a fun game, but let’s not take it too seriesly.

Orpheus, the imaginary planet/asteroid. It doesn’t exist. It never existed. The moon was not formed because of a collision. It’s all SPECULATION and “What If”.

It would then coincide with the procession of the equinoxes every 24k then? The graph of glacial/interglacial periods I shared above in #16 taken from ice cores shows a regular shift in the cycle on an average of every 24,000 years. I am firm believer that we set our sites to short trying to find just one cause, when it could be a combination of several different influences happening at the same time.

Wildebeest are extinct?

That's gnus to me.

I agree. as the mass extinction events were done by either a solar flare or impacts.

When we have a pole shift the magnetic field weakens making us very vulnerable to a large solar flare.

Ick. I saw her on that cable tv show where she was having sex with some white dude, shrunk him up and sucked him up into her vajayjay.

[buzzer noise] It's important to point out that the Younger Dryas Impact Hypothesis is the only idea for which there is any evidence.
