Serious question because askscience never lets me post it . How will we ever know if we find perpetual energy ? We can ' t prove anything will go on forever . <| sep |> My SO told me he has one last night . I was shocked , but I don ' t judge him for anything from his past . I was very happy that he told me . Meant a lot to me . <| sep |> She got more votes straight up , she won the popular vote . She got fewer EC votes , she lost the EC vote the election . No need to be petulant about this . <| sep |> Advertising comes to mind . A celebrity or athlete can license their image , and they can have a professional actor and a voice impersonator do the actual ad . Also , politics . Imagine you have a candidate that is intelligent and highly qualified but has zero charisma you know , a leftist . You can have someone else do their expressions on televised speeches . Slightly different than Waldo , the politician is actually the politician , but the technology is used to make them more likeable .
