The second largest component of the universe is dark matter. The truth is, we understand little of what it is, and more of what it is not.
Space exploration has come a long way since the first primitive satellites—we’ve visited all the canonical planets, and laid the groundwork for the next stage of discovery and colonization. A new, more lasting space race is about to begin. Here’s the second part of our 100-year forecast of future space exploration.
Fusion rockets, Bussard ramjets, SK drives, world ships carrying thousands of colonists and entire ecosystems—these are just a few of the ideas to get us to the stars. In this handy guide, we’ve assembled some of the best proposals for interstellar travel, ranging in likelihood from the near-term achievable to the far-out implausible.
Soon, we may have a viable way to make antimatter.
Our space probes have reached nearly every corner of the Solar System—so our restless species sets its sights on remoter shores. The recent discovery of a potentially habitable planet around our nearest stellar neighbor has us wondering: what else is out there? Here’s a look at the most intriguing targets in the Solar Neighborhood.
Will science fiction once more meet science fact?
The emission of gamma rays at the center of the galaxy could be the result of dark matter annihilating “dark antimatter.”
A former Fermilab physicist is starting a crowdfunding campaign to build an antimatter drive.
Physicists previously detected anomalous readings in the decay of a B meson, which may mean the existence of physics beyond the current theory.
The asymmetry of matter and antimatter is one of the biggest mysteries in physics. But new results detailing the charge of antihydrogen just helped close some of these gaps.
