    Research reveals that plate tectonics started on Earth 600 million years before what was believed earlier... Where it was previously thought that plate tectonics started about 2.7 billion years ago, a team of international scientists used the microscopic leftovers of a drop of water that was transported into the Earth's deep mantle - through plate tectonics - to show that this process started 600 million years before that. An article on their research that proves plate tectonics started on Earth 3.3 billion years ago was published in the high impact academic journal, Nature, on 16 July... For their research, the...

    The Truth about Radiometric Dating June 2019 Prove it. That’s the challenge biblical creationists often face when discussing the scientific validity of the Genesis creation account with skeptics. Many people leave the church, especially young adults, when they think that the Bible and science can’t be harmonized. But what if incredible harmony actually exists? Those who believe in millions and billions of years often point to radiometric dating as indisputable scientific proof that Earth is old. Since the biblical timeline indicates a young earth that’s only about 6,000 years old, creation scientists must address the radiometric dating issue. We need...
  • How valleys and canyons formed during Noah’s Flood

    How valleys and canyons formed during Noah’s Flood by Micheal Oard Continental valleys and canyons come in all sizes and shapes. Some are V-shaped valleys, and others U-shaped canyons. Some are shallow and others have tall vertical walls, like the Grand Canyon. We rarely observe valley and canyon formation taking place today and then only in association with a flooding event. Therefore, uniformitarian1 theories about valley and canyon formation are not built on observational science but instead upon their assumptions about the past.
  • Earth is missing a huge part of its crust. Now we may know why. (Thieves?)

    The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million years to 1.2 billion years is missing. Known as the Great Unconformity, this massive temporal gap can be found not just in this famous crevasse, but in places all over the world. In one layer, you have the Cambrian period, which started roughly 540 million years ago and left behind sedimentary rocks packed with the fossils of complex, multicellular life. Directly below, you have fossil-free crystalline basement rock, which formed...

    A hidden "super volcano" near Pompeii threatens an eruption that could make Vesuvius look like a picnic, scientists warn. The Phlegraean Fields zone of intense seismic activity -- which the ancient Romans believed was the gateway to hell -- could doom millions of people in the Naples area if it erupts, Reuters reports. Scientists plan to drill more than two miles below its surface to monitor any signs of a pending eruption in the huge chamber of molten rock, but some experts fear that the drilling itself could trigger an earthquake or eruption. Areas like the Phlegraean fields "can give...

    Scientists have discovered a stunning volcanic ‘lost world’ off the coast of Tasmania. Experts on the Commonwealth Scientific and Industrial Research Organisation (CSIRO), vessel ‘Investigator’ made the find while mapping the seafloor 249 miles east of Tasmania. The project is led by scientists from the Australian National University. CSIRO is Australia’s national science agency. A chain of ‘seamounts’, or undersea mountains, were spotted in deep water, offering the first glimpse of a spectacular “underwater world.” Scientists say that the mountains rise up to 9,843 feet from the seafloor, but the highest peaks are still 6,562 feet beneath the waves. “Our...
  • Grisly discovery: Bones reveal Neanderthal child was eaten by large bird

    Tiny holes in the bones indicate that they passed through a large bird’s digestive system, according to Professor Pawel Valde-Nowak of the Jagiellonian University in Krakow. It’s not clear, however, whether the bird attacked and ate the young Neanderthal or scavenged the remains of a dead child. Believed to be about 115,000 years old, the bones are the oldest human remains ever discovered in Poland. Experts from the Jagiellonian University and Washington University in St. Louis confirmed that the remains are digital bones from a child’s hand. The Archaeological Museum of Krakow and the Polish Academy of Sciences also participated...

    Just because Jupiter's moon Europa is coated in ice doesn't mean all that ice is the same temperature. And now, scientists have mapped the hot and cold spots on the moon's surface using data gathered from Earth, with accuracy down to 125 miles (200 kilometers). While most of the temperature variations they measured can be explained by sunlight's influence on the ice, there's one unusually cold spot that is stumping the scientists behind the new research. That spot, which falls on the moon's northern hemisphere, stood out in images taken at different times of the day, which surprised the scientists....

    The Meghalayan...runs from 4,200 years ago to the present. It began with a destructive drought, whose effects lasted two centuries, and severely disrupted civilisations in Egypt, Greece, Syria, Palestine, Mesopotamia, the Indus Valley, and the Yangtze River Valley. The Meghalayan Age is unique among the many intervals of the geologic timescale in that its beginning coincides with a global cultural event produced by a global climatic event... The middle phase of the Holocene will be referred to as the Northgrippian, and runs from 8,300 years ago up to the start of the Meghalayan. The onset for this age was an...
  • Geologists surprised to find huge magma blob under Massachusetts, Vermont and New Hampshire

    Something unexpected has been gradually making itself known to geologists in the United States. A huge mass of molten rock is creeping upwards beneath the nation’s north eastern states. “The upwelling we detected is like a hot-air balloon, and we infer that something is rising up through the deeper part of our planet under New England,” says Rutgers University geophysicist Professor Vadim Levin. Traces of the brooding mass only became evident through a large-scale new seismic study. The idea that there may be a super volcano brewing under Massachusetts, Vermont and New Hampshire is something of a surprise. ..." So...

    New York City could be hit with a $39 billion in damage with 30 million tons of debris clogging the streets if a long-overdue earthquake hit. The city of 8.5 million people is not thought of as a tremor hot spot, but the five boroughs are riddled with fault lines that could bring dozens of buildings down. Because the city is so dense and littered with thousands of tall buildings, even a 5.0 magnitude earthquake nearby would cause such damage, experts fear.

    "One of the prime areas of research for Mars planetary geologists is the region on Mars where the geography appears to transition from the southern cratered, rough terrain to the northern low, generally smooth, and flat plains. It is theorized by some scientists that the northern plains were once an ocean, probably shallow and probably intermittent, but wet nonetheless for considerable periods..."

    Once upon a time there was a massive flood across the Mediterranean Sea, an in-pouring of water so huge that it excavated a canyon five kilometres deep and 20 kilometres long, and created a waterfall with a 1.5 kilometre drop. Evidence for the great flood, long hypothesised, has now been found by a team of researchers led by geoscientist Aaron Micallef from the University of Malta. And while several Mediterranean traditions feature great flood narratives, the earliest arising from Sumeria and already well enough known to be recorded in cuneiform by the seventeenth century BCE, this one is unlikely to...

    Researchers at UCLA and the University of Wisconsin-Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth. An example of one of the microfossils discovered in a sample of rock recovered from the Apex Chert, a rock formation in western Australia that is among the oldest and best-preserved rock deposits in the world. The fossils were first described in 1993 but a 2017 study published by UCLA and UW-Madison scientists used sophisticated chemical analysis to confirm...

    From the Everglades in the US to the Great Barrier Reef in Australia, climate change is destroying the many of the greatest wonders of the natural world. A new report on Monday from the International Union for Conservation of Nature (IUCN) reveals that the number of natural world heritage sites being damaged and at risk from global warming has almost doubled to 62 in the past three years. Those at high risk include iconic places from the Galapagos Islands to the central Amazon and less well known but equally vibrant and unique sites such as the karst caves of Hungary...
