I've actually seen this Ted talk before, and I don't think it prove that consciousness die with the brain. If there's a part specifically that proves that, please share. Nope. But consider a counter question - can all living beings cease to exist in the universe? I'm not talking about specific points in time, because we know there was a time between the creation of the universe and the fist living being. I'm talking a universe without life across all of it's existence. We know only of one universe and it has life in it. Therefore we can't be sure that universe can exist without life (without consciousness, or spectator). Please share how do you imagine this nothingness? Since the universe continue to exist, where does this nothingness fit in? How can nothing exist in something? There can be either nothing, or something, not both. And we have already agreed that something continue to exist.
