Charles Darwin was not yet 30 when he got the basic idea for the theory of evolution. But it wasn’t until he turned 50 that he presented his argument to the world. He spent those two decades methodically compiling evidence for his theory and coming up with responses to every skeptical counterargument he could think…
Does E always equal mc²? University of Arizona physicist Andrei Lebed suspects not – and plans to try and check. Einstein’s famous equation describes the fact that energy and mass are essentially the same thing and can be converted into one other. It’s since been validated in countless experiments and calculations – indeed, many technologies…
The Large Hadron Collider will operate for two more months then shut down through 2014, allowing engineers to lay thousands more superconducting cables aimed at bringing the machine up to “full design energy.” This will vastly improve its capacity to simulate the moments after the Big Bang nearly 14 billion years ago.
The 12 matter particles we know about are all the types there are, according to researchers analysing CERN data. Matter particles, also called fermions, are the elementary components of the universe, making up everything visible in the universe. “For a long time, however, it was not clear whether we know all components,” says Professor Ulrich…
Many mysteries surround black holes, but new research led by the Niels Bohr Institute has come up with groundbreaking new theories that might explain several of their more mysterious properties. The new study reveals that black holes have properties that resemble the dynamics of both solids and liquids. Black holes are extremely compact, so compact…
Caltech physicist Sean Carroll makes the search for the Higgs boson a scientific detective story. At heart is the mystery of the universe.
Amir D. Aczel blogs about physics and cosmology for Discover’s Crux: If somebody told you that there are angels floating in space, observing our world and forming their impressions of our everyday reality, you would think that this person is nuts—a religious fanatic with an active imagination, and certainly not a scientist. Scientists, as we…
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published in Nature Physics. It is based on what the researchers call a ‘hidden influence inequality.’…
NASA astronomers have discovered a stunning trend in galaxy evolution, according to a report from the space agency. The stunning trend in galaxy evolution goes back 8 billion years, say astronomers who looked at numerous galaxies through the Keck telescopes and NASA’s Space Telescope. “Astronomers thought disk galaxies in the nearby universe had settled into…
Cosmologists are uncovering relics from the dawn of time, letting them look back almost all the way to the Big Bang.
