Exploring Science, Religion, and the Big Bang
Physicists used to believe that the universe existed forever, there was no beginning, and there would be no end. The universe seemed as constant, as dependable as the night sky that never failed to show up, night after night. Of course, this view conflicted with religions that had stories on the creation of the universe. So it makes sense that the Big Bang Theory--the idea that our universe had a beginning, because it's expanding--was first developed by a priest.
Georges Lemaître, a Belgian Roman Catholic priest, astronomer, and professor of physics at the Université catholique de Louvain, was the first to propose that the universe was expanding. His work paved the way for the Big Bang Theory.
But is physics taking us back to the theory that the universe is in fact eternal? MinutePhysics explores the science and some of the religion behind the Big Bang Theory:
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
