Re: First evidence of other universes that exist alongside our own after scientists spot 'cosmic bruises
The article says "A number of cosmologists have already written in response to the paper that it is too easy to jump to conclusions about what can be seen in the CMB."
I wouldn't have a clue of how to interpret such evidence. With such an extraordinary claim, I wish the journalist had tried to get a more detailed comment from other scientists as to what else it might be, and how speculative this is. I suspect that everyone, including the scientists, likes to spin a good story about it. We'll see if it holds up.
