Is it Really possible to rollback the world ?
I usually finish my lunch alone or normally not talk too much..and normally thinks abt problem i a facing with my project ....
but today some thing else ....(may be becoz y`day was Newton`s B`Day 25th Dec )
Can we really go back in history ? i mean in past time frame, Think abt going into past say 11th sept. 01 , and correct all entities ....
i got a very small idea, if we can manage 65656928608 (World 6,565,692,7860 8:20 GMT (EST+5) Dec 26, 2006 ) threads then it may be possible we can roll back or commit changes in history (but this clause will contradict history can`t be changed) but these threads are only population threads and if we consider all entities with whome these human objects can interact (in the world forget abt universe) the combination can`t be measured. we can`t store even that number them how could we think abt we can maintain log of all interactions that will take place between these entities with their surrounding entities.
so what i mean is complete rollback is not possible a this stage even if we can log all interaction. and even in a synchronised manner.
May be we can think abt partial rollback or commit means using a context i.e. an entiey and its surrounding obejcts, but in this case surrounding objects is not a stricts defined boundary, as it is possible, a trigger from far remote place (means having long geological separation) cause an action so surrounding obecjts are not defined, and thats why i think partical rollback is not possible. and even a surounding object is an entity and it has its surrounding entities means all are connected and we can`t use concept of partical rollback.
what could be other possibilities if any one can have with him please share ..
these words sounds very foolish, but may be these words define a rollbackble world.
come on, think abt it
