The sad reality is space travel like sci-fi will most likely never happen. For the following reasons;
-No faster than light travel
-using wormholes etc..to get around light speed requires way to much energy, like stars to whole galaxies worth. Can't imagine ships with stars/galaxies worth of energy inside their power plants.
Right on, well said, Using warp drive and worm holes may be a possible way of going
faster then the speed of light, but the problems with these technologies is that
they take to much energy and even if you could power these devices, it would be
illogical because the energy of a star could be use for more importent things like
powering a civilization for billions of years, instead of going on a round trip to the ofter side of the galaxy just to visit a dead barren world.
And please don't me about these higher dimensions that we can use to travel faster
then the speed of light, because I have three reasons why we can't use these
dimensions in the first place.
1. There is no guarantee that these higher dimensions exist at all, because there
is no evidence to support there existence and please don't tell me that
scientist say that higher dimensions exist because they only say that these
dimensions are theoretical.
2. Even if higher dimensions do exist, there is no guarantee that we can open one
up and go in one.
3. If we can open up a dimension and go in one, theres no guarantee that humans or
machines or the ship itself, would survive the trip to make it to its
destination, examples why humans, machines and the ship would not survive the
trip in the dimension would be, High energy radiation would disable the ship and
kill all the humans on the ship and unkonwn forces could tear apart the ship,
or there might be a entity that would attack the ship and destroy it. The laws
of physics might be diffent in that higher dimension and the ship might not work
well or may not work at all in that dimension and the same might go for the
humans to and I can list more examples, but I don't have the time.
