(Credit: NASA/JPL-Caltech) By Jake Parks | February 7, 2018 On February 4, astronomers using the NASA-funded Catalina Sky Survey (CSS) detected two asteroids with orbits that take them between Earth and the moon this week. Fortunately, neither object’s trajectory presents a threat to Earth. In fact, the week’s first visiting asteroid — dubbed asteroid 2018 CC — has already completed its closest approach to Earth. The small rocky body zoomed by our planet on Tuesday, February 6, at 3:10 p.m. EST, just 35 minutes before SpaceX launched their Falcon Heavy rocket. Asteroid 2018 CC, which is estimated to be between 50 and 100 … Continue reading Asteroid To Pass Between Earth and Moon On Friday

Bill Retherford , CONTRIBUTOR Opinions expressed by Forbes Contributors are their own. Check out the architecture of our solar system. Little planets close to the star, big planets far away. Scientists once supposed the other star systems in the Milky Way would look about the same. “That’s what we used to think,” says Andrea Ghez, UCLA professor of physics and astronomy. But researchers discovered otherwise after finding the first few hundred or so exoplanets. “None of them conformed,” says Ghez. “It was … Continue reading Surprise — Our Solar System’s Not Like The Others
image edied by Fernando Kaskais by Chelsea Gohd NICHD Human Entropy Our species has long agonized over the concept of human consciousness. What exactly causes it, and why did we evolve to experience consciousness? Now, a new study has uncovered a clue in the hunt for answers, and it reveals that the human brain might have more in common with the universe than we could have imagined. According to a team of researchers from France and Canada, our brains might produce consciousness as something of a side effect of increasing entropy, a process that has been taking place throughout the universe … Continue reading New Study Links Human Consciousness to a Law That Governs the Universe
What would it have been like to witness the beginning of the universe? NASA New research has investigated the amount of light available in the newborn universe, which may offer some clues. By Thomas Kitching Something wonderful happened about 13.8 billion years ago. Everything in the universe was created in an instant as an infinitesimally small point of energy: the Big Bang. We know that this event happened, as the universe is constantly expanding and galaxies are moving away from us. The more we peer into the past, the smaller it gets – that’s how we know it must have once been … Continue reading What was it like witnessing the beginning of the universe?
image edited by Fernando Kaskais By Mike Wehner, BGR We live in a three-dimensional reality. Because of that, it’s pretty hard to imagine what a four-dimensional reality might be like, but that isn’t stopping physicists from trying to figure it out. A pair of new research papers were just published in the journal Nature that explore the possibilities of a fourth dimension and, as difficult as any of this may be to comprehend, it seems the scientists are on to something. The papers, which focused on two very differentexperimental approaches to detecting a fourth dimension, arrived as similar conclusions. But before … Continue reading Studies find evidence of a fourth dimension
image edited by Fernando Kaskais by Kristin Houser Creative Commons The Nature of Space and Time A pair of researchers have uncovered a potential bridge between general relativityand quantum mechanics — the two preeminent physics theories — and it could force physicists to rethink the very nature of space and time. Albert Einstein’s theory of general relativity describes gravity as a geometric property of space and time. The more massive an object, the greater its distortion of spacetime, and that distortion is felt as gravity. In the 1970s, physicists Stephen Hawking and Jacob Bekenstein noted a link between the surface area of black holes and their microscopic … Continue reading Scientists Are Rethinking the Very Nature of Space and Time
image edited by Fernando Kaskais by nbcmach Creative Commons Nuclear war. Runaway climate change. A global pandemic. Today our world faces all manner of existential threats. But scary possibilities like these are nothing compared to what astronomers say lies in store for Earth. Our planet’s ultimate destiny is to be baked, blasted, and eventually disintegrated. There’s nothing we can do to prevent this cataclysm. Yet according to scientists who study the far future, including University of California astronomer Gregory Laughlin, the prospect for life is, oddly, rather bright. Given technological advances and the continuing evolution of our species, humans should be … Continue reading How Humans Might Outlive Earth, the Sun, and Even the Universe Itself
