Physics, Astronomy & Cosmology / What if the universe really is infinite?
« on: 18/10/2021 13:02:08 »
Watching a Horizon programme last night on BBC 4 (Sean Caroll was one of the contributers)
Apparently the Cosmic Microwave Background Map is like an expanding bubble around anywhere in our "neighbourhood" and its features have now been mapped in enough detail to "draw" a huge triangle from here to there.
The triangle ,according to the programme is evidence that space (spacetime?) is probably flat and as a result the universe outside the observable part is of infinite extent.
What might be the implications if this,startlingly is true and can we now posit this provisional result as a stone to build our edifice of how "everything" works.
Can we ditch the "universe may be finite" for good unless we get some new unexpected observations in the coming years or centuries?
