: In my opinion I believe that a wormhole is not the same as or not even a related phenomenon : to the blackhole due to the fact that a wormhole is theoreticly a tunnel which is escapeable but a blackhole is unescapeable by anything slower than the speed of light. Unless a wormhole is infact a blackhole connecting to a whitehole but if that was the case it would only be one way.

: : : Who has any opinion as to whether or not black holes are portals to another universe or maybe wormholes to another point in this universe but in another portion of time-space? Any opinions?

Well wormholes can't naturally exisit because anti gravitons have to support the wormhole. But maybe in the future we may be advanced enough to create one
