you are a geek..im really blown away

@neurocrater ok, wait, scratch that stuff about worm holes, it would fold 4D space along 5D space, however, the requirements for folding one instance of 4D space are enormous and incredibly destructive in the alternative space. Using ripples in alternative space as a short cut (changing alternation twice) seems much more efficient to me. Then again, theoretical physics got so many things wrong...

[NightmareJoker2]

@neurocrater The 6D idea is from the following derivation:

There is an infinite amount of space, or a fixed amount of space where the outlines of said space are that vastly apart as to be infinite in distance. Therefore in whichever perceived dimensional space you reside, there is always another dimensional space occupied by the former residents.

The 6th dimension is not a wormhole, since a wormhole is to be a 3D space connection between 2 points in space, which would fold along time itself.

@neurocrater alternation is what you perceive occuring, if you travel consciously through space-time (4D space) in 5D space. The instance of space where the object originated will still persist, even though all logic would tell us it can't, in case you manipulate 3D space in 4D space in such a way that the "future" instance of 3D space would result in a different 4D instantiation.

[neurocrater]

@NightmareJoker2 what is alternation? that term only references "snubbing" of complex 3D geometrical objects. it doesn't seem to exist as any other space or dimensional-related term. is there another word for it? what does it refer to mathematically/conceptually?

is the last point u're talking about something like a wormhole, where 3D space can be conceptually folded along a 4th spatial dimension to connect two disparate points? but that's not a dimension per se.

where is the 6D idea from?

[NightmareJoker2]

@neurocrater horizontal space, vertical space, depth of field, time, alternation and then there's this one dimension which enables a directional connection between two points in 5 dimensional space, no idea what you'd call it.

[neurocrater]

@NightmareJoker2 objects can travel through 6 dimensions?

[jiberish001]

Time exists only as our interpretation of events passing.

[NightmareJoker2]

Time is merely the 4th dimension of the 6 known dimensions through which objects can travel.
