The Big Bang and the visible past.

You want to talk about BB( and contradict it) when you couldn't even define a straight line? Are you actually serious? The problem is that you don't even understand such basic concepts. Of course, it makes you feel you are right because you ignore even your own ignorance, but others see how ignorant you are and just don't want to bother with you derailing an interesting topic where we actually try to understand real science. It's not your place to redefine anything when you can't even define the most basics of concepts.
