Previous warp drive designs relied on a source of exotic matter unknown to physics.
The new design reimagines the shape of warped spacetime to allow for normal matter and energy to be used instead.
Warp drive is having a moment. Just last week, scientists dropped a bombshell when they unveiled the first physical model for a warp drive, the holy grail of space travel that would allow us to bend the fabric of space and time to their will and overcome the vast distances separating humans from the stars. Now, another astrophysicist has delivered an equally exciting warp drive breakthrough.
