The OP's post rests on the Anthropic Principle. Essentially, we don't see evidence of a Type III civilization because anyone who dies is very quickly thereafter consumed by that civilization as it expands across the observable universe. It's a terrifying idea.
- darkmighty 12y agoNote those are two distinct explanations. OP's point about the speed of light explains only why we're not observing any civilization from the last 50,000 years, while the anthropic principle and the "quick, devouring species" assumption explain why no alien life exists at all in our past light cone.
- maaku 12y agoYes, and those were both my points :)
