Moontanman Posted April 27, 2021 Share Posted April 27, 2021 (edited) Is slower than light warp drive possible? Maybe we are passing up a possibility that would open up the solar system without the negative mass required to go faster than light? I couldn't find much on the idea but Sabine Hossenfelder mentions it in this video at about 02:30. https://iopscience.iop.org/article/10.1088/1361-6382/abdf6e Quote Conceptually, we demonstrate that any warp drive, including the Alcubierre drive, is a shell of regular or exotic material moving inertially with a certain velocity. Therefore, any warp drive requires propulsion. We show that a class of subluminal, spherically symmetric warp drive spacetimes, at least in principle, can be constructed based on the physical principles known to humanity today Edited April 27, 2021 by Moontanman Link to comment Share on other sites More sharing options...
beecee Posted April 27, 2021 Share Posted April 27, 2021 First I have heard of Sabine...I love the rather "thick" pronunciation of Einstein. Interesting video. 1 Link to comment Share on other sites More sharing options...

I am rather fond of Sabine, she cuts through the gobbledygook and makes her field understandable. As a bonus she sings, often about science. 1 Link to comment Share on other sites More sharing options...
