1.Possibility of the existence of extraterrestrial life Life is one of the most fascinating mysteries of nature.With the advances in space science and technology,life science has developed to the stage of exploring the possibility of existence of life outside the Earth system.In other words,by ...
Life can deal with a wider range of conditions. Miller had probed the origin of life by passing electricity through a glass container of organic chemicals to see what came out. Bada found fascinating hints that the origin of life may well be on an Earth-like planet rather than the ...
000 years ago -- and there is no other meteorite quite like it. The 7-11 kilogram grey rock -- seared glassy black on the outside by the heat of entry, called a fusion crust -- showed evidence of water. It was
But around the time of the rise of plant life, thecontentof thosesedimentlayers began to change.The coarse grains became much finer, and we seeevidenceof mud. This suggests that plants promoted the preservation of mud when they sent their roots into the ground. The roots helped toreinforcethe...
Revealing negative information about Elon Musk pains me greatly because I agree with many of his policy positions and his professed secular beliefs about freedom in all spheres of life, including speech. However, I cannot ignore Musk's potential dark side, so I must warn everyone so you can ...
Interactions between the Earth and incoming materials from the Solar System have dramatically influenced the evolution of life on Earth, well exemplified by the extinction of the dinosaurs caused by the Chicxulub impact event (Alvarez et al., 1980; Hildebrand et al., 1991; Kring and Boynton, 19...
DOP, its temporal nature and its spatial distribution will allow its role in abyssal ocean ecosystems to be better understood. Future studies of DOP in the deep sea may also shed light on broader relationships between metal-oxide deposition, biological evolution and the oxygenation of Earth16,17....
but he couldn't prove it…because he only had evidence from the one North American mountain chain.But his studies gave him an idea about why rivers started to change—he hypothesized it had to do with the spread of plant life on Earth.FEMALE STUDENT: So … there was no plant life befor...
Breathing new life into Charles Hapgood’s theory of earth crustal displacement/pole shifts, a new paper proposes that short-term reversals of the geomagnetic field may “unlock” the crust sufficiently to allow tidal forces to pull it over the mantle in the same way they move earth’s oceans...
