Yes but that is because you are uneducated in relativity. There was zero evidence for the world being flat, there is mounting of evidence to support e=ym0^2.About the lightspeed barrier, personally i think its similar to the earth is flat theory in that one day it was discovered to be false.
Yes but wormholes have not been proven to exist or be possible to construct. I dont know about the second one, but wasnt it the plot to a movie or something?But even if this is the case there 2 theories(maybe more but 2 technology based methods to my knowledge) of other ways to travel which bypass this barrier(wormholes, and changing the vibratory frequency of the craft to the point where it and its occupants change states, from material to energetic). I may not be wording that correctly, but from what ive read this changing to pure energy form exits you out of time therefore you are not limited by physic's "laws".
An alternate theory.... Maybe the highest or most powerful transportation methods arent even technology based, you see the pictures of the huge headed aliens right? perhaps it is mental powers which they travel by(instantaneous teleportation) Jesus is quoted as saying something like "Do ye not know ye are Gods?" and "All these wonders i do, you will do and even greater things" those are paraphrased but it gets my point across.
Peace
Youre just wetting your pants embarrassing yourself now.
