Welcome to the Multiverse
Sean Carroll: The multiverse might be impossible to test directly. Even if such a theory were true, the worry goes, how would we ever know? Is it scientific to even talk about it?

Although the world produces enough food to feed everyone, two million children die of malnutrition every year. Food insecurity has become a symbol of inequity and remains the most crippling consequence of poverty. Campaigners for food security must include science in their goals — and in return scientists need to heed wider concerns around solutions….
Need to study induced seismicity in response to the string of suspicious quakes in shale-gas drilling areas.
The equivalent of an MRI of the sun was created by scientists, who studied high-resolution images of the sun’s surface taken by NASA’s Solar Dynamics Observatory showing motions on the sun’s surface caused by convection. The findings challenge our existing explanations of the formation of sunspots and magnetic field generation. Author Metanexus Editors
NASA’s long-running Voyager 1 spacecraft has entered a new region at the edge of the solar system and is close to exiting it forever. Scientists have dubbed this region the “magnetic highway” and it’s the last stop before interstellar space, or the space between stars. Voyager 1 and its twin Voyager 2 launched 35 years…
Scientists have known for almost five years now that the moon is watery–or at least that lots of water molecules are trapped in its crust and its permanently dark, frozen craters. The prevailing theory is that this water comes from molecules in the solar system. But maybe the moon has had water all along, according…
Of the many mysteries of modern physics, few compare to “nonlocality” in quantum physics. Nonlocality means that far away objects can influence one another instantaneously (or, at least, much faster than the speed of light). It is as if space and time didn’t exist! “Influence” may not be the right word here; in fact, we…
