With ref to the Speed of Light

[I amso IR]

Seems as tho no one knows, based upon the above responses. I appreciate the responses as I cannot answer the question either. My question involves another unknown, the warping of space for faster space travel. Seems to me that time would have to be added for the slowing of time encountered as the vehicle increases to "warp speed". That may be something to consider when planning the trip to the closest galaxy Alpha Centauri as it is 4.367 light years away or according to Space.com 25.6 trillion miles or 25,600,000,000,000,000 miles distant which would probably require two extra sack lunches. What is even more mind twisting is that a large number of Americans have never traveled more than 80 miles away from home and they had three extra lunch sacks. Just spoofing about sack lunches. Where the hell is Matthew when you need him?
