It would be possible if wormholes weren't just theory..
First of all, Schwarzschild came up with this:
ds2 = -(1-2GM/r)dt2+(1-2GM/r)-1dr2+r2dΩ2
with dΩ2 being the normal differential portion of a sphere: dθ2+sin2θdφ2
With math, you can convert to Kruskal coordinates:
X2 - T2 = (r/(2GM)-1)er/2GM
and
T/X = tanh(t/4GM)
Then you can conclude that the event horizon = r > 2GM
Which means that the singularity at the center of the black hole: X2-T2 = -1
Which gets X2-T2 < -1 which is physically impossible.
Well, I guess not since at T=0, there is a hole, but the objects going through wouldn't be able to if they're going slower than the speed of light since t!=0 closes up the hole..
