It's not impossible for something to arise out of nothing. Well, what I really should say is, it's not impossible for two somethings to arise out of nothing, as long as they have opposite charge and annihilate when they come into contact.
I like to imagine there's an anti-universe moving backwards in time from the start of the universe, and that's where all the unexplained missing baryonic antimatter ended up.
- tadfisher 4y agoSo the universe is a crazy huge Feynman diagram that got split at the edge of a black hole? Cool.
- smolder 4y agoPut in other words, something is a subset of nothing! This idea fits in well with the unprovable MWI as well. If every possibile configuration of spacetime exists, and in a symmetry where everything has an opposite, doesn't it all kind of "add up" to 0? This idea has been in my head since high school physics many years ago.
- mensetmanusman 4y agoIf one redefined nothing as something, then the universe can arise.
- jgrowl 4y agoI think this comment is actually very insightful. If you assume that 'nothing' is what cannot exist, then everything becomes a matter of scale and instrument sensitivity
