20+ Science Facts We Didn’t Know at The Start of 2017 | sciencealert.com

"1. The speed of gravity is pretty much identical to the speed of light! This year, for the first time ever, scientists were able to photograph a collision between two neutron stars. By conducting simultaneous optical and gravitational wave observations, they were able to accurately measure the speed of gravity for the first time. 2. A brand new human organ …

Moon is proto-Earth’s mantle, relocated | Geology Page

"Measurements of an element in Earth and Moon rocks have just disproved the leading hypotheses for the origin of the Moon. Tiny differences in the segregation of the isotopes of potassium between the Moon and Earth were hidden below the detection limits of analytical techniques until recently. But in 2015, Washington University in St. Louis …

Potential Energy Source for Life Spotted on Saturn Moon Enceladus

"Saturn's icy moon Enceladus is looking more and more like a habitable world. The same sorts of chemical reactions that sustain life near deep-sea hydrothermal vents here on Earth could potentially be occurring within Enceladus' subsurface ocean, a new study published today (April 13) in the journal Science suggests. These reactions depend on the presence …

Inside the Artificial Universe That Creates Itself – The Atlantic

"Every particle in the universe is accounted for. The precise shape and position of every blade of grass on every planet has been calculated. Every snowflake and every raindrop has been numbered. On the screen before us, mountains rise sharply and erode into gently rolling hills, before finally subsiding into desert. Millions of years pass …

First test of rival to Einstein’s gravity kills off dark matter | New Scientist

"A controversial approach to gravity that challenges Albert Einstein and suggests dark matter doesn’t exist has passed its first test. The vast majority of physicists agree that gravity acts according to rules laid down in Isaac Newton’s law of gravitation and Einstein’s theory of general relativity. Yet observations of the universe show that the motion …

This New Equation Promises to Unify Physics Theories with the Help of Wormholes | Big Think

"As far as famous equations go, none are more known than Einstein’s E=mc2. This insight by Einstein that relates mass and energy has been linked to the creation of a new kind of physics and the birth of the atomic age. Leonard Susskind, professor of theoretical physics at Stanford University, and one of the founders of string …

Is There Any Plausible Reason Why Aliens Would Evolve To Look Like Us?

"In science fiction movies and TV shows, intelligent aliens are usually the same basic shape as humans: two arms, two legs and a head. But why would creatures that evolved on a completely different planet look so similar to us? We asked some experts, and they told us the most likely explanations for humanoid aliens. …

Theory that challenges Einstein’s physics could soon be put to the test | Imperial College London

"Einstein observed that the speed of light remains the same in any situation, and this meant that space and time could be different in different situations. The assumption that the speed of light is constant, and always has been, underpins many theories in physics, such as Einstein’s theory of general relativity. In particular, it plays …

Physics tweak solves five of the biggest problems in one go | New Scientist

"It’s not a bad day at work. Five of the biggest fundamental problems in physics seem sorted in one go. The model that can do this, formulated by Guillermo Ballesteros at the University of Paris-Saclay in France and his colleagues, may explain dark matter, neutrino oscillations, baryogenesis, inflation and the strong CP problem. Dubbed SMASH, the model …

Astronomers Detect Strange Star Signals That Are “Probably” Aliens Making Contact | Big Think

"Two Canadian astronomers published a study that claims an anomaly in the pulsing of a group of stars is possibly evidence of an alien civilization. It’s easy to be skeptical of any such proposals but the scientists really do consider an extraterrestrial involvement as one of the potential explanations to what they’ve observed. The scientists …

E.T. Phones Earth? 1,500 Years Until Contact, Experts Estimate

"Aliens may be mediocre just like Earthlings, which could explain why humanity hasn't heard from advanced civilizations yet. If life on this planet develops at an average pace, rather than an exceptionally slow pace, then extraterrestrial life likely followed a similar path. Like humanity, average civilizations have barely scratched the surface of galactic communication, so …

Scientists claim to have discover what existed BEFORE the beginning of the universe | Physics-Astronomy

"To explain it in simple and easily understandable terms; they applied the theories of the very small i.e. the world of quantum mechanics, to the entire universe - explained  by general theory of relativity, and discovered the universe essentially goes through four different phases. More importantly they discovered what came before this universe was.. Another …

Hubble Finds 10 Times More Galaxies Than Thought | NASA

"The results have clear implications for galaxy formation, and also helps shed light on an ancient astronomical paradox - why is the sky dark at night? In analyzing the data, a team led by Christopher Conselice of the University of Nottingham, U.K., found that 10 times as many galaxies were packed into a given volume …

Big Bang, Deflated? Universe May Have Had No Beginning At All | Physics-Astronomy

"A new theory claims that the universe may not have started with a bang. According to this new study, the universe was not ever a singularity or an infinitely minor and infinitely dense point of matter at all. In actual fact, the universe may have no start at all.
