The recent observed gravitational wave is claimed due to two merging black holes colliding or infusing into each other. Could it be just another local Big Bang? (Of course I am implying Big Bang occurs in various scales). So "our Big Bang" was a large scale Big Bang and was triggered by two immensely densed black holes merged at, say, light's speed? For another example: Moon was created for a small scale Big Bang. What's your take?
