A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal ...

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 ...

To travel the stars without faster than light travel we’re going to need a generation ship. In the far future we may have advanced propulsion technologies, but what if those technologies never ...
