For more than a century the speed of light was treated as an unbreakable cosmic limit. Now physicists are revisiting that ...

For the first time, a group of physicists is arguing that a warp drive is not just a mathematical curiosity but something that fits within the known laws of nature. Instead of relying on exotic ...

In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star–just before it vanished from view. The ...

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the ...

If humanity wants to be a spacefaring species, it needs to figure out how to travel faster than the speed of light. Now, a new online toolkit — backed up by a $500,000 grant — will help engineers ...

From science-fiction technologies like warp drives and levitation to the search for evidence of intelligent life elsewhere in ...
