When an asteroid approaching the Earth flies through the planet in a passage that is as close as the EarthMoon neighborhood, the least significant consequence is drama. It is calibration: an ...

For more than half a century, faster than light travel has lived in the realm of television scripts and paperback science fiction. Now a cluster of theoretical breakthroughs is forcing physicists to ...

All the “normal” matter, like the stars, gas, dust, and people, is called baryonic matter, and it’s basically the tiny visible fraction of a universe that’s mostly invisible and still not fully ...
