we sway into scifiction which i want to be realistic: How is it inside Subspace or Hyperspace or a cosmic string (from the perspective of different theories)? Can we even enter cosmic strings (if we say we had the technology)? Has the subspace (enbedded in our 4 dimensions) or the hyperspace (it surrounds us) a mass ? What means 1-dimensional, i understand it´s one line and only forward or backward, but what are the consequences for ppl entering it ? Is there a time-dimension (4th dimension, or here the 2th), does it mean there is no time ? If theres no time will we (the space ship) freeze when we enter ? What do the leading theories say about the subspace, hyperspace and cosmic strings (and the String Theories) ? Are SS, HS and CS conflicting with quantum machanics or with one of theories of relativity ? Did any of the prestigious scientists describe a realistic characteristic (how it is inside) of the SS HS or CS ? Here is a hypothetical scifiction scenario i have, but i dont know how realistic it is: we enter a cosmic string, or the subspace or hyperspace. The cosmic strings are predicted to be 1-dimensional but i dont know about the SS or HS. If we say it´s a place without time, the space ship will be everywhere at the same (or freeze). Now if we find the way out, we travelled in no-time through the HS, SS or CS (even faster than Star Treks warpspeed). Like a cosmic string from one star to another star, we enter it and have arrived in 1 second (overlooking the mass of such a lightyears long cosmic string).
