A research team consisted of scientists from different parts of the globe and led by a group of scientists from University of Liverpool’s School of Environmental Sciences has analyzed the magnetic records from ancient igneous rocks. The analyses revealed that the strength level of Earth’s magnetic field was significantly different between 1 billion and 1.5 billion years back.
The theory talks about the presence of a higher magnetic field and points out to the first appearance of solid iron in Earth’s core. The scientists leading the study believe that it was also the time when our planet’s inner core started solidifying and freezing.
It is found that around 4.5 billion years back i.e. before the formation of Earth’s solid inner core, the planet used to be a massive sphere of liquid rock. Scientists say that with time as the surface started to get cooler, the molten mess developed a crust. According to them, the solid core of the planet is a 1 billion old structure, which make sit relatively younger.
The study’s lead author Dr. Andy Biggin said that the findings of this new study might change the way we perceive the layers of our planet and its history. Biggin added that according to the study, the temperature of our planet’s core is dropping at a much slower pace than what we previously believed. According to him, this finding will have a substantial impact on all departments of Earth Sciences.
During the study, Biggin and his team found that the diameter of the Earth’s core increases by 0.04 inches (1 mm) every year. The size of the planet’s inner core right now is similar to that of Pluto.
According to the study team, our planet’s magnetic field, which keeps it protected from harmful solar radiation, is the main reason we have life on Earth. Further research on Earth’s core and its magnetic field will help scientists to predict the planet’s electromagnetic future.
The key findings acquired so far suggest that Earth’s magnetic field and its strong core is capable of staying powerful for another billion years. The data put forward by the study is the exact opposite of similar data about Mars. Mars’ magnetic field was high during its early years but disappeared 4 billion years back.
The entire study was published in the popular science journal Nature on October 7, 2015.

NOT MILLIONS OF YEARS OLD! Evolutionary dating methods are not infallible science, are based on certain built-in assumptions, and have been proven to be contradictory and inconsistent. Please read my popular Internet article, ARE FOSSILS REALLY MILLIONS OF YEARS OLD?
There is absolutely no proof of macro-evolution in the fossil record. The fossils of all species are found complete (not partially-evolved) with no evidence of actual transition from one kind to another. There are no fossils of fish, for example, with part fins, part feet to show that transition occurred from fins to feet. Besides this, partially-evolved species would be unfit for survival while waiting to be completed over millions of years.
The fossils show that all life came into existence as complete and fully-formed from the beginning, which is only possible by creation.
The fossil layers in the real world are not even found in the sequence taught in evolutionary textbooks. There are many places where fossils of complex creatures are found beneath simpler ones, and there are fossils of mixed species existing in the same stratum which classic evolutionary textbooks teach should have been separated by millions of years.
There’s a lot of evidence that the fossil layers were not deposited by gradual floods, which would have required millions of years. Rather, the evidence strongly points to a one world-wide flood that fossilized species, just as the Bible teaches. All the fossils that have been used to support human evolution have been found to be either hoaxes, non-human, or human, but not non-human and human.

NATURAL LIMITS TO EVOLUTION: Only evolution within biological “kinds” is genetically possible (i.e. varieties of dogs, cats, etc.), but not evolution across biological “kinds” (i.e. from sea sponge to human). How could species have survived if their vital tissues, organs, reproductive systems, etc. were still evolving? Survival of the fittest actually would have prevented evolution across biological kinds! A true transitional form would be unfit for survival. For example, “if a leg of a reptile were to evolve (over supposedly millions of years) into a wing of a bird, it would become a bad leg long before it became a good wing” (Dr. Walt Brown, scientist and creationist). Survival of the fittest actually would have prevented evolution across biological kinds! Read my Internet article: WAR AMONG EVOLUTIONISTS! (2nd Edition).
Natural selection doesn’t produce biological traits or variations. It can only “select” from biological variations that are possible and which have survival value. The real issue is what biological variations are possible, not natural selection. Only limited evolution, variations of already existing genes and traits, is possible. Nature is mindless and has no ability to design and program entirely new genes for entirely new traits. Evolutionists believe and hope that, over supposedly millions of years, random genetic mutations in the genetic code caused by environmental radiation will generate entirely new genes. This is total blind and irrational faith on the part of evolutionists. It’s much like believing that randomly changing the sequence of letters in a romance novel, over millions of years, will turn it into a book on astronomy! That’s the kind of blind faith macro-evolutionists have.
Mutations are accidents in the genetic code, are mostly harmful, and have no capability of producing greater complexity in the code. Even if a good accident occurred, for every good one there would be hundreds of harmful ones with the net result, over time, being harmful, even lethal, to the species. At best, mutations only produce further variations within a natural species. Even so, mutations are not the best explanation for variations within a natural species.
If life on earth had really existed for millions of years, all species would have become extinct by now due to the colossal number of accumulated mutations over time (please read the author’s popular Internet article, ARE FOSSILS REALLY MILLIONS OF YEARS OLD?).
What about “Junk DNA?” It’s not junk. It’s we who were ignorant of their usefulness. These so-called “non-coding” segments of DNA have recently been shown to be vital in regulating gene expression (i.e. when, where, and how genes are expressed, so they’re not “junk”). Even more recent scientific evidence shows that they do code for proteins, after all, and that we need to readjust our thinking of how the cell reads the genetic code (Read “Human Proteome More Complex Than Previously Thought,” Internet article by Dr. Jeffrey Tomkins). Read my popular Internet article: HOW FORENSIC SCIENCE REFUTES ATHEISM
Since it’s not rational to believe genetic information can arise by chance, it is totally rational to believe that God (the Supreme Genetic Engineer) placed within all natural species, in the beginning, with all of the recessive and dominant genes to produce all of the variations found within natural species (i.e. varieties of dogs, cats, horses, cows, etc.).
Since genetic information, like other forms of information, cannot arise by chance, it is far more logical to believe that the genetic and biological similarities between various species are due to a common Designer (Creator) who designed similar functions for similar purposes in all the various forms of life.
