The 'past' and the 'future' are not part of existence....
existence/reality is a whole unified field of continuously active energy/vibrations...
it never stops...it never stores part of itself anywhere else (there is no place 'anywhere else' - See
here
for more.)
If we could make an image of it..it might look like this:
Repetition gives the illusion of form etc. but everything is always moving.
Just like we know the earth is spinning about 1040 miles/hr but it seems like it's still. more on repetition
here.
The past...our partial recordings...memories.
The future....our projections....
Everything is always in the now...
no where else exists
For us to go to a former movement of the unified field ( a 'past' configuration) you would have to get everything in existence to reproduce the former movement...and even then if such a task were possible it would just be a current reproduction...man that hurts my head just thinking about it.
