Earth stuck between gravitational tug of Jupiter and Venus which is causing abrupt weather changes

What Kent and his colleagues did was expand the record of those cycles by digging out cores of Earth hundreds of feet long from Arizona and Northern New Jersey. They used the natural clocks provided by radioactive materials and signs of reversal of the Earth’s magnetic field to figure out when and how the climate changed.

Scientist Claim Earth to be an hollow planet and is filled with Aliens

In an astonishing find, researchers have confirmed a longstanding hypothesis that Earth is stuck between the gravity of Jupiter and Venus and both the planets play with the trajectory of our mother Earth. According to the scientists, orbit of Earth if warped by the gravitational pull of Jupiter and Venus in an epic cycle that repeats regularly every 405,000 years.

“It’s an astonishing result because this long cycle, which had been predicted from planetary motions through about 50 million years ago, has been confirmed through at least 215 million years ago,” says geomagnetics researcher Dennis V. Kent from Rutgers University. “Scientists can now link changes in the climate, environment, dinosaurs, mammals, and fossils around the world to this 405,000-year cycle in a very precise way.”

The effect is an example of Milankovitch cycle and to confirm it, the researchers have observed the phenomenon for decades.  Study authors explained that in Milankovitch cycles planet’s circular orbit around the Sun shifts and becomes nearly 5 percent elliptical and then the planet again moves in the circular trajectory.

However, study authors were sceptical about the effect of Milankovitch cycles on Earth and wanted to find for how long back it has affected Earth’s trajectory. For the study, researchers drilled ancient rocks from deep under Arizona’s Petrified Forest National Park.

In 2013, Kent and his team began drilling rock cores in excess of 1,500 feet long (457 metres) from a butte in the park, analysing them for radioisotopes that indicated their age and evidence of reversals in the polarity of the Earth’s magnetic field.

When they compared them with sediment samples from the Newark basin – a former prehistoric lake that spanned most of New Jersey – they found that the 405,000-year cycle is the most regular astronomical pattern linked to the Earth’s annual turn around the Sun, which dates as far back as 215 million years ago, to the Triassic period.

“There are other, shorter, orbital cycles, but when you look into the past, it’s very difficult to know which one you’re dealing with at any one time, because they change over time,” says Kent, who is also affiliated with Columbia University.

“The beauty of this one is that it stands alone. It doesn’t change. All the other ones move over it.”

By confirming that this steady, metronome-like 405,000-year cycle dates back to a time before even the reign of the dinosaurs, the findings have implications to innumerable fields of research – potentially affecting how we interpret fossils and trace the evolution of life forms, to understanding more about planetary movements.

But perhaps the most topical area of science this could help us understand is pinning down how Jupiter and Venus – incredibly distant though they are –affect Earth’s climate, and how it inevitably undergoes heating and cooling changes over vast timeframes.

Not that anybody should be pointing to this study and insisting our planet’s current climate woes are due to anything but human activity, the authors point out, as the multi-millennial pace of this Milankovitch cycle’s effects aren’t something we could notice in our short lifetimes.

“Climatic cycles associated with the impact on our planet of Jupiter and Venus, and major changes occur every 400 thousand years. And these changes, as shown by geological deposits appear stable for hundreds of millions of years. That is celestial mechanics plays a major role in changing the climate, and therefore flora, fauna on the Earth.”

“It’s pretty far down on the list of so many other things that can affect climate on times scales that matter to us,” says Kent.

“On the other hand, all the CO2 we’re pouring into the air right now is the obvious big enchilada. That’s having an effect we can measure right now. The planetary cycle is a little more subtle.”

  • Looking at this mechanically, I have speculated that the Sun, Moon, Mars and occasionally Jupiter have had affects concerning the tidal activity of Earth. I was surprised one day to discover that there are “Earth Tides”. Thus this may affect volcanic and earthquake activity on our Planet. Now, what is it, every three to five years as part of a cycle or pattern and as Venus and Earth come close to each other it forms a Pentagram. So, even Venus can have some influence on oue dear Planet.

  • The premise is quite unworkable. No orbit is a “set” orbit based on some arbitrary “mathematical artificial formula of equality”. Every orbit is a feedback relationship between the gravity of a large central body and much smaller planetary orbiting bodies and their “inherent tangential speed to that gravity force at the time of the start of the first orbit. And all planets in our solar system, particularly as they come within the vicinity of other planets which orbit around the same sun “add” their gravity force to the mix (tho in a very minor way compared to the mass of our sun). And that feedback causes the earth to zig zag back and forth across a nominal width band as the angle of application of the gravity force changes. As long as it stays within the limits of correction and reversal the feed back can provide it matters not that Jupiter or Saturn, for example add a bit of their gravity to the mix when they pass by on our side from the sun. It just another “adjustment just like those constantly being made in our orbit itself.
    Just one of many concepts astronomers have missed. Not unlike that for 1500 years they insisted to the point of killing those that disagreed that all the stars rotated around the piddly earth. You’d think they would have at least chosen the sun upon which humans depend for their survival. And the sun being much larger could care less if the earth is there or not. Rathgic.com will have an more complete explanation when I get the time to publish it.
