Consciousness is a state, not an object.
It is like asking me if running would stop after the race, or if the engine would stop after the car was shut off.
It’s not like asking me if my legs would still exist after the race, or if the engine would still exist after the car was shut off.
No, it is like asking me if the current still exists in the circuit after power has been removed from the battery and the circuit decays into being separated matter of another form.
Let me put it this way to elaborate further.
Water is a collection of water molecules.
When together, we have water.
If I take a cup of water and stir the water therein, then I can say that I have current.
If I take away the cup and let the water move to another basin, then there is still water with current.
If, however, I put the cup down and walk away, then the current will eventually cease over a long enough time.
Once it stops, it will rest.
Could I regenerate the current in that water?
Sure, that’s easy; I walk up and excite the water. It is a simple compound so that is not too difficult.
The more complex the compound, the more difficult such an event becomes.
But if I leave that water alone, it will evaporate.
The hydrogen will begin to separate from the oxygen slowly.
Essentially, the water will begin its version of decay.
Eventually I will be left with an empty cup.
The current was first to stop, then the water separated its bonds and departed.
If I wait long enough, the cup will also decay, separating its bonds.
Once the water separated its bonds and hydrogen and oxygen left in separate motives, it is no longer water.
The atoms still exist that existed in that cup of water, but they do not exist in their arrangement that made them the water, nor do they exist in proximity to each other in their respective and individual forms they have taken in leaving the unity of being water.
Instead, they have atomically left to join and bond with other atoms and create other compounds useful for other means that are not the body of water that they were a part of previously.
And in even this, the current that was present in the body of water hasn’t any relation at this point of existing at all.
It now only exists as a concept of what has taken place in the past but is no longer taking place.
That specific arrangement of atoms moving in that specific manner in which they could; that current; it is no more and never will be.
