>¿Estás seguro? Este articulo de Scientific America dice lo contrario:

He leído el artículo y no contradice nada de lo que he dicho:


"Similarly, the big bang happened everywhere--in the room in which you are
reading this article, in a spot just to the left of Alpha Centauri,
everywhere. It was not a bomb going off at a particular spot that we can
identify as the center of the explosion. Likewise, in the balloon analogy,
there is no special place on the surface of the balloon that is the center
of the expansion."

Lo que el artículo dice al final es que NO PUEDES NOTAR la expansión (ni
como cambio de fuerzas ni separación ni nada)

Además añade: "This reasoning changes if acceleration is not constant, as
some cosmologists have speculated. If the acceleration itself increased, it
could eventually grow strong enough to tear apart all structures, leading to
a "big rip." But this rip would occur not because of expansion or
acceleration per se but because of an accelerating acceleration."
