Assume time is fundamental but not a phenomenon/illusion derived from random movements of particles

Assume parallel universes of dimensions 3 exists and the resultant flow rate of time is fixed to n

Time will be like space flowing in one direction, i.e. a vector in space

If the space which contains the universes is 4D+t while our universe is 3D+t, we will have two directions for time to point to

So our universe will have time with flow rate n while in a neighbouring universe the flow rate will be -n

Now expanding the space which contains the universes to 5D+2t. We can have universes with its time vector pointing in any direction on the 'time plane'. this result in the vector placed at some angles [theta] away from t

_{1}axis. Therefore if we resolve the orthogonal components of this vector. We'll get the following:

Flow rate at t

_{1}axis: ncos[theta]

Flow rate at t

_{2}axis: nsin[theta]

For organisms such as us who can only sense time in 1D only within such a universe, we will sense the flow rate of either ncos[theta] or nsin[theta]

For organisms who can sense 2D time, they will sense the flow rate of n and with an extra parameter to indicate the 'direction'

,however i've no idea what will the extra parameter will be like if we can sense it.

The above can be generalized to arbitary no. of time dimensions

Combining with the P/F theory of probability as a continuum, this will result in splitting of timelines

These are my thoughts after reading serval sci fi stuffs in describing timelines, correct me if I'm wrong

Edit:

Another idea is that time is flexible

Assume the time travel and history altering event below does not lead to grandfather paradox

Assume the actual 1st building is built on 1898

Time travel back to e.g. year 1846 and another building is built.

1. From the perspective of past and future, it seems the 1846 building is built earlier than the 1898 one

2. But after knowing there is a time travel event and that time still flows forward before and after time travel

we will know that the 1846 building is built later than the 1898.

If we consider the 2nd case, the timeline is like bending back to 1846 and then continue to the future as usual.

This gives us something like 'time displacement' and 'time distance'. Time here is sort of 2D

And this arguement gives us a theory that time is space like with a unidirectional 'flow' like component

P.S. For the grandfather paradox case, this result in 1t+1p(robability)+3D, according to the P/F theory
