" ... Like the decay of a radioactive atom, such shifts in energy state happen at random and it is possible that this could trigger a new big bang. The good news is that theory suggests that the universe should remain in its current state.
But the bad is that quantum theory says that whenever we observe or measure something, we can select out a specific quantum state from what otherwise would have been a multitude of states, each of which could have been selected out with varying probabilities.
In this case however, it turns out that quantum mechanics implies that if an unstable system has survived for far longer than the average such system should, then the probability that it will continue to survive decreases more slowly than it otherwise would.
Thus, as a result of making cosmological observations of dark energy, we may have confirmed that we are in a state where the probability of its survival may fall exponentially. ... "
