The Idea of Creating a New Universe in the Lab Is No Joke

wormholecropped‘Physicists aren’t often reprimanded for using risqué humour in their academic writings, but in 1991 that is exactly what happened to the cosmologist Andrei Linde at Stanford University. He had submitted a draft article entitled ‘Hard Art of the Universe Creation’ to the journal Nuclear Physics B. In it, he outlined the possibility of creating a universe in a laboratory: a whole new cosmos that might one day evolve its own stars, planets and intelligent life. Near the end, Linde made a seemingly flippant suggestion that our Universe itself might have been knocked together by an alien ‘physicist hacker’. The paper’s referees objected to this ‘dirty joke’; religious people might be offended that scientists were aiming to steal the feat of universe-making out of the hands of God, they worried. Linde changed the paper’s title and abstract but held firm over the line that our Universe could have been made by an alien scientist. ‘I am not so sure that this is just a joke,’ he told me.

Fast-forward a quarter of a century, and the notion of universe-making – or ‘cosmogenesis’ as I dub it – seems less comical than ever. I’ve travelled the world talking to physicists who take the concept seriously, and who have even sketched out rough blueprints for how humanity might one day achieve it.’

What Do Aliens Look Like? Oxford Astrobiologists Base Picture on Evolution

 

oxford-alien-drawings‘When Charles Darwin laid out his theory of natural selection in 1859, little could he have imagined that, a good 150 years later, this cornerstone of evolutionary theory might help us form a mental picture of what alien life looks like. But that’s precisely how a group of researchers from Oxford University have done: In a research paper called “Darwin’s Aliens,” they’ve applied Darwin’s theory to alien life, positing that aliens–like humans–adapt to their environment, undergo natural selection, and move from simple to complex life forms. And, by the end, they could plausibly look something like a “colony of Ewoks from Star Wars or the Octomite” pictured above.’
