People always talk about how vast space is, but rarely about how vast time is. We&#x27;ve been looking for life for the last what, 60 years or so? It seems like not only is space so vast which makes finding evidence of life hard, but this is made even harder by the small volume of time we are likely to be around to try and observe in the grand scheme of things. Alien life has to be relatively close in terms of distance as well as time.<p>What if our closest alien life became discoverable (started emitting radio signals or other signs) a million years from now? Would we be around to see it?
