Ok I have had a course is general relativity, but not on special. I was wondering something though... If you have a brick wall a light year long (when at rest) and then have it thrusted at you at a speed such that it is only 1ft long, i.e. .99999c, when would you be able to stand in front of it without being hit by the wall? For example does it bunch together in the middle so you can stand in front of it for 6 months or maybe it bunches towards the front so you can move into its path after just a split second? The weird thing is that if you look parallel to it you should see for the whole year right? Just something I thought was fun to think about, any thoughts?
