A team of researchers in Sweden has developed a new Warp drive model that does not require exotic matter to function, as opposed to previous designs by Alcubierre and White. Published in a peer-reviewed journal, their design is based on classical physics principles and does not allow for faster-than-light travel. The researchers emphasize that their drive can approach light speed, making interstellar travel feasible without the need for exotic materials. Unlike previous warp concepts, their proposal eliminates the dangerous radiation emissions associated with superluminal drives. While the current equipment may not be sufficient to test their physical warp drive, the team remains optimistic about future advancements. They are exploring ways to enhance their design, including the possibility of manipulating time within the warp shield region to shorten travel durations. Despite the challenges ahead, the researchers believe their project represents a significant step forward in real-world warp drive technology, grounded in sound physics principles.

It still requires negative energy
- The new "engine" only slows time inside the spacecraft. It doesn't "push" the spacecraft; it needs conventional engines to actually move. Travel is not faster than light, not even for its passengers.
- Outside time still passes normally. Spacecraft speed as seen from an external observer is still the same. It doesn't help a space probe, except maybe batteries would last longer "inside". It doesn't help a spacecraft crew - everyone they knew at home would be dead by the time they return and they'll be ancient cavemen by comparison. It marginally helps a colony ship; it doesn't have to be a generation ship anymore.
Also slightly unsure about their insistence on propellant as a means of locomotion, as opposed to hanging out a sail and riding solar winds toward the nearest gravitational slingshot.
Are there any other proposals out there today which address the risk of travelling through the interstellar medium at a high percentage of c?
