If just .001% of 10 billion Earth-like planets orbiting sun-like stars in the Milky Way have harbored advanced, intelligent life, shouldn’t we have seen some kind of evidence of their past existence, since this would equal 100,000 civilizations?

Great question! Complicated answer. Let’s start by looking Earthward at ourselves, then we’ll compare that looking spaceward toward the stars. As you know, homosapiens are the advanced, intelligent life form on Earth which is now technologically advanced and space faring. Now by some estimates, humans have been on this planet only for the last 200,000 […]

Leave whatever planet it happens to be in the original pristine condition so we can study it. (This is the predominant, tree hugging concept.) Screw number 1. Terraform the planet. Make it livable for humans, […]

Why would anyone want to live on Mars?

Although, scientifically, we could do as much or more with our rovers, robots and probes than manned space travel, and we can and do it cheaper and safer than manned space travel with our probes and rovers, people will still go to Mars. Why? Well, I suppose it’s the same reason people went to North […]
