A simple proposal for a way to pursue some answers to the origins of life
Can strings be the ultimate constituents of the universe–more fundamental than matter or energy, and even than space or time? If they’re not made of matter or energy, what are they, then?
Here’s a treat for fans of movies and the brain: an article called Strange Continuity. Throughout evolutionary history, we never saw anything like a montage.
From humanity’s first, flawed foray to the surface of a comet to the celebrated discovery of (and less celebrated skepticism about) primordial gravitational waves, 2014 has brought some historic successes and failures in space science and physics.
Comfortably sitting in the Sundance Kabuki Cinemas in Japantown in San Francisco, I was watching The Theory of Everything with an audience of hundreds.
Christopher Nolan’s new film, Interstellar, is a near-future tale of astronauts departing a dying Earth to travel to Saturn, then through a wormhole to another galaxy, all in search of somewhere else humanity could call home.
Excitement is building — at least in science circles — for the upcoming announcements of the 2014 Nobel Prizes, along with the inevitable speculation about who might be among this year’s winners.
Black holes break theories. These sites of extremely large masses in extremely small spaces invoke both of the behemoths of modern physics—general relativity (which rules over large masses) and quantum mechanics (which reigns in small spaces).
Editor's Note: Welcome to ANITA, the Antarctic Impulsive Transient Antenna! From October to December, Katie Mulrey is traveling with the ANITA collaboration to Antarctica to build and launch ANITA III, a scientific balloon that uses the entire continent of Antarctica for neutrino and cosmic ray detection.
Welcome to the seventeenth installment of You Should Know, where I give my own#ScholarSunday salute to Science Bloggers and the Blogs you may not yet know about.
The big physics news this week was the announcement of the long-awaited results from the Planck missions — and the news is not good for the BICEP2 collaboration: the Study Confirmed Criticism of BICEP2′s original Big Bang Finding. They may have had space dust in their eyes.
At a 1990 conference on cosmology, I asked attendees, who included folks like Stephen Hawking, Michael Turner, James Peebles, Alan Guth and Andrei Linde, to nominate the smartest living physicist.
Imagine you are a 5th grader while watching this video. Would you love it? If it caught your interest, as it did mine, you are in good company. This is the winning entry for the 2014 Flame Challenge put on by Alan Alda and the Center for Communicating Science.
The image you see here is a computer-generated model of the black hole at the center of the Milky Way, which we call Sagittarius A*. More precisely, it is a model of the "shadow" that Sagittarius A*, with its mass of four million suns, should cast.
This is a guest post by my friend Pinkesh Patel, a data scientist at Facebook. Pinkesh has a PhD in physics from Caltech during which he worked on LIGO, the gravitational wave detector.
Physics, unlike biology or geology, was not considered to be a historical science until now. Physicists have prided themselves on being able to derive the vast bulk of phenomena in the universe from first principles.
No matter how many times you’ve seen the movies and the TV shows that have a protagonist leaping in the path of a bullet, physics forbids such sacrifice.
Two weeks ago, I blogged about David Bohm’s interpretation of quantum mechanics. Like Einstein and Louis de Broglie before him, Bohm argued that quantum randomness is not intrinsic to nature, but reflects our ignorance of a deeper level of reality.
Scientific American editor Clara Moskowitz has a nice post showcasing some of the big questions asked by participants at a recent particle physics conference.
One night in 1952, Richard Feynman and David Bohm went bar-hopping in Belo Horizonte. Louisa Gilder reconstructs the night in her brilliant book on the history of quantum mechanics, The Age of Entanglement.
