Perfect experiment for a first time science fair project

The closer the timeline of life on Earth gets to the appearance of humanity, the less our ancestry is doubted among scientists, and there is virtual certainty that is humanity’s direct ancestor. Their brains were nearly the size of modern humans and they inherited from their ancestors and used them for hundreds of thousands of years. There is plenty of evidence that migrated to Western Eurasia about 800 kya. But there is evidence that somewhere around 500 kya that began to change; there is evidence of in today’s South Africa. in today’s Germany, along with butchered horses, dated to about 400 kya. Scientists today are confident that was also the direct ancestor of , and the split began around 500 kya. The range of was Africa, West Asia, and Europe, but the advancing and retreating ice sheets of Eurasia, Europe in particular, kept driving southward, and during one of the retreats, it seems that the ancestors of Neanderthals stayed. Neanderthals became a cold-adapted species that specialized in hunting big game. As the evidence demonstrates today, life was a brutal proposition in humanity’s early days, and was particularly harsh for Neanderthals. They probably could not throw very well and relied on ambush predation. Scientists have studied Neanderthal bones and , but a , partly in light of recent evidence that Neanderthals may have also developed wooden throwing spears. But whether Neanderthals had to stab their prey in close quarters or eventually learned to throw weapons at them, the studies of early human bones describe a grim existence. Breaking bones were regular events, particularly skull fractures, and that was for trauma survivors.

A foolproof science experiment your preschool or kindergarten kids will love!

This chapter will provide a somewhat detailed review of the Cryogenian Ice Age and its aftermath, including some of the hypotheses regarding it, evidence for it, and its outcomes, as the eon of complex life arose after it. The ran from about 850 mya to 635 mya. This review will sketch the complex interactions of life and geophysical processes, and the increasingly multidisciplinary methods being used to investigate such events, which are yielding new and important insights.

Alaska Science Forum/The Hollow Earth Theory by Larry Gedney.

I was also regularly dismayed by orthodox scientific and academic works that dealt with the human brain, consciousness, human nature, , FE technology, and the like, in which the authors accepted declassified government documents at face value (as in not wondering what else remained classified, for starters) or looked no further than 19th-century investigations. Direct personal experience is far more valuable than all of the experimental evidence that be amassed; there is no substitute for it, as that is where comes from. Armchair scientists who accept the skeptics' word for it have taken the easy way out and rely on unreliable "investigators" to tell them about the nature of reality. They consequently do not have informed opinions, or perhaps more accurately, they have opinions. The holy warriors’ efforts aside, the scientific data is impressive regarding what has been called “psi” and other terms, which clearly demonstrated abilities of consciousness that are still denied and neglected by mainstream science. , but he was a voice in the wilderness.


A short creative story about traveling to the center of the earth

In the 1990s, I found the dating issue enthralling and saw it assailed by fringe theorists and by . A couple of decades later, I reached the understanding that, like all sciences, dating has its limitations and the enthusiasm for a new technique can become a little too exuberant, but dating techniques and technologies have greatly improved in my lifetime. Dating the , and using 100,000-year increments to place the dates, may seem a conceit, thinking that scientists can place that event with that precision, but over the years my doubts have diminished. When and can be tested, and the findings support not only Earth’s age previously determined by myriad methods, but also support the prevailing theories for the solar system’s and Moon’s formation, call me impressed. Controversies will persist over various finds and methods used, and scientific fraud certainly occurs, but taken as a whole, those converging lines of independently tested evidence make it increasingly unlikely that the entire enterprise is a mass farce, delusion, or even a conspiracy, as many from the fringes continue to argue. There is still a , and it is not a parody. I have looked into fringe claims for many years and few of them have proven valid; even if many were, their potential importance to the human journey was often minor to trifling. As the story that this essay tells comes closer to today’s humanity, orthodox controversies become more heated and fringe claims proliferate.

White science still has almost nothing to say about the nature of consciousness. However, Black Science (covert, largely privatized, and the same province where that ) is somewhat familiar with the nature of consciousness and considers it to be far more than a byproduct of chemistry. The assumption that the entire universe is a of consciousness is not only by White Science, but is probably a foundational assumption of Black Science mystics.
