General reminder: the Alcubierre warp drive does not allow you to accelerate to from sub-c speeds to above-c speeds. This back-reaction post discusses the topic, linking to a paper on a better design for an Alcubierre warp drive: http://backreaction.blogspot.com/2020/11/warp-drive-news-seriously.html http://backreaction.blogspot.com/2020/11/warp-drive-news-ser...
- matt123456789 5y agoThanks for the link. Of the three major concerns raised by Sabine about halfway through the article, my (uneducated) take is that this work addresses the first one: production of an apparent negative energy distribution.
- zardo 5y agoI believe it's an even harder constraint, it does not accelerate at all.
