University of Wisconsin – Madison and Northwestern University has found evidence which is confirming a critical theory of how the planets in our solar system actually behave in their orbits around the sun.
New Evidence Of Chaotic Solar System
The finding published on 23rd February 2017 in the journal nature is very important this is because it provides the first hard proof for what scientists call the “Chaotic Solar System”. A theory was proposed in 1989 to account for small variations in the present conditions of the solar system. The variations are playing out from over million of years and produce big changes in our planet’s climate – changes which can be reflected in the rocks that record the Earth’s history.
The discovery promises not only a better understanding of the mechanics of the solar system but also a more precise measuring stick for a geologic time. It also offers a better understanding of the link between orbital variations and climate change over geological timescales. Using evidence from alternative layers of limestone and shale laid down over million of years in a shallow North America seaway at the time dinosaurs held sway on Earth.
The new study was supported by the grants from the National Science Foundation. It builds on a meticulous stratigraphic record and important Astro chronologic studies of the Niobrara Formation. The latter conducted in the dissertation work of Robert Locklair who is a former student of Sageman’s at Northwestern.
The impact of astronomical cycles on climate can be a quite large and explains Meyers noting as an example the pacing of the Earth’s ice age which have been reliably matched to periodic changes in the shape of the Earth’s orbit and the tilt of our planet on its axis. “Astronomical theory permits a very detailed evaluation of the past climate events which may provide an analog for future climate.
The study shows the connection between sedimentation and climate change. From this study, it has been found that Earth has changed its climate due to the effects of resonance transition. This shows that the Earth has been affected by the chaotic nature of the early solar system. Other studies have suggested the presence of chaos based on geologic data. But this is the first unambiguous evidence which is made possible by the availability of high-quality radioscopic dates and the strong astronomical signal preserved in the rocks.
