Alright so 11 dimensions with our universe being a ripple formed by to branes colliding in one. If this is true in theory while we spend our time trying to build engines faster and with less fuel consumption wouldnt it be more feasible to build an inter-dimensional engine that can jump to the 11th dimension where it would be as simple as entering the brane at a different location no need for extended fuel o2 or resources..... In theory any thoughts disagree/agree just a thought
Yeah I guess it is a little out there all hypothetical and what Ifs... That being said yesterday's dreams are todays reality but I probably should change the thread location Please Register or Log in to view the hidden image!
Actually my General Relativity term paper was specifically about interstellar travel through higher dimensions. In theory, if you assume a certain spacetime structure to the universe and assume that there's some kind of magic higher-dimensional matter which can curve spacetime in the correct way, then you can travel as fast as you like. I didn't have the complete technical knowhow (or time) to investigate all the consequences in detail, but to preserve causality in the 4 dimensions we already know about, it seemed under this scheme you would have to introduce some sort of artificial restrictions on what kind of "wormholes" you could make from one part of the universe to another, specifically restrictions on times of departure and arrival which would somehow depend on the values already set for other wormholes in the area.
Im Glad I'm not the only one who thinks it may be possible. Any chance you have a copy of your term paper I could read?
I do still have it and wish I could share it, but unfortunately I have to be cautious about giving out personal info or details that could potentially be used to identify me. Even if I took my name off the paper, in principle it could still end up on the web one day, and then in the future you might be able to find it on Google just by using one of the paragraphs as a search query. It was a bit rushed, I felt there was more I could have done with it, and I was a bit worried because it was about faster than light travel, which is considered a speculative fringe topic in physics... but I passed the course, so I guess the prof didn't think it was crazy enough for a fail (and he did point me to some valuable resources which made my paper possible in the first place). Anyway a lot of the work was just rehashing theoretical speculation from other papers (mine was just a term paper, not an original publication). The main justification for the topic was to present an alternative model which might solve the Horizon Problem by allowing faster than light travel in the early universe. I cited a hypothetical higher-dimensional spacetime metric and the accompanying higher-dimensional stress-energy tensor (which describes the mass that would cause such curvature) from a published paper, described some of the basic consequences, and then added a few little details of my own, but most of what I wrote I had already read from others at the time, or (to my delight) found in other physicists' writings later on.
