Greetings all, I am the newest addition of the PF community and let me express my excitement of finally tracking down this intelectual family and hopefully making myself eventually an equal member of it. Now, I will not waste too much of your time let us get down to this PFbuisness=pleasure, shall we? I may be just an enthusiast in the world of astrophysics in general but there is something that disturbs me: Most educational literature I have come across persistantly visualises the force of gravity and similar phenomena in insuficient dimentions. A typical example would be a visual representation of the curvature of space-time, inflicted by the gravity of an interstellar body. They simply put down a 2D web, curved by the object that sits upon it. We all know that this is simply an insuficient representation, just as as saying "the sun comes up", which is simply inacurate. So what I would like to ask is what is their motivation for disseminating such information in such an oversimplified manner? It also may be a possibility that I have simply come across such items which were designed for a low level laiman, in that case I would apreiciate it if you could direct to some "higher-level" materials on the topic of astrophysics, preferably some video please or scientific columns with more accurate information... Thank you all and have a nice day!
