All this speculation is based on our miniscule understanding of cosmology and associated sciences.
What if Einstein was wrong and we can travel faster than light speed? This would significantly change how we view the cosmos and how things work within it.
The entire issue is so big, so complex and so beyond our understanding (based on the restraints of current science) that we merely postulate on what is presently possible and what may be possible as our knowledge improves of the unimaginable vastness that is space.
It is good to excercise the brain however - which is why I find these threads so interesting.
All very true Zulu, and as I keep on saying "we", mankind, know nothing yet!
We are still babes in arms, being nurtured by the great universe, and starting to learn about it's many facts.
In anycase we know we can travel faster than the speed of light. Even the early Starship
Enterprise got up among the lower warp speeds, so what will the future Starships accelerate to?
Science fiction? Well of course!!
But what the human imagination produces today is totally possible some time in the distant future
Absolutely nothing can be ruled out once the universe has taught us its facts.
ie 1960 in school all books and teachers claimed that light could only travel in straight lines and we believed it.
2011, we are used to light travelling, and being bent to travel, in all different directions!
