Back to my busy week!
Erik
Thanks for starting a blog!
ReplyDeleteCurious about your response to https://arxiv.org/pdf/2102.06824.pdf
ReplyDeleteI plan to make a post about this other paper soon. Keep and eye out. Thanks!
DeleteHey Erik,
ReplyDeleteI have a question that I was hoping you could help answer.
During my personal thoughts and speculation on FTL travel and long distance space travel the thought crossed my mind, how do we compensate for space FOD and other large objects during long distance space travel?
Assuming we are traveling in a vessel via point to point line of sight. Even if we have a destination, there is no way of knowing what could be on the other side of a FTL "slip stream" or what could be in between. We could be flying into another planet or asteroid or even a rock the size of a penny tearing into the fuselage that could be catastrophic.
Maybe I'm miss understanding you're theory and it would not be an issue "if it would be technically bending space fabric in a point in time" but what physical consequences could be applied to any objects or planets between our start point and our destination point?
Again, I'm not questioning your theory or objecting at all. Im just stumped on this. Just thinking outside the box!
This is a very interesting question that probably requires its own post to address properly. I will say that there has been some work through the years on what would happen to exterior objects that encounter an Alcubierre warp bubble. One particular study that comes to mind (https://arxiv.org/abs/1202.5708v1) shows that objects become "time locked" in the shell of a constant velocity bubble and can become stuck in the leading edge of that bubble if it is moving faster than light.
DeleteYou mention that originally linear and elliptical solutions had been tried (which led to a requirement for negative energy sources) and that your approach critically differs in using hyperbolic solutions. My question is whether you know that parabolic solutions might be fruitful?
ReplyDeleteI spent time thinking about both hyperbolic and parabolic relations among the shift vector components. I chose the hyperbolic relations -- specifically a linear wave equation -- as the geometric properties were simpler to interpret and derive. I do think parabolic relations remain a promising avenue.
DeleteI really like that you have this blog for people to follow your research and news about everything related to it! Thanks very much for that!
ReplyDeleteOne question I have is, when looking at previous warp drive research, it seems people (like Alcubierre) usually wrote one single paper, and then left their research at that state they described in that paper, moved on to different research, and then some other people many years later found some improvements (usually in regards to lowering the required energy).
Based on what I've understood you saying in your recent talk on Youtube, it sounds like you hope to write some more papers potentially exploring energy reduction of your, may I call it, "Lentz Drive", and that you'd also like to explore solutions to the problem of accelerating/decelerating it, right?
That's really great of course that you do not seem to view your research as "done" yet! I just wonder, and I find that an interesting enough question that I want to ask it here, how comes your approach to this differs from how people traditionally treated their warp drive research? Am I right in saying your approach seems to differ quite significantly, in a good way?
hello ....i was reading your article on positive energy warp bubbles metrics , can you help me wit some materials on the mathematical derivation of the hyperbolic forms ?
