The term 'Big Bangs' refers to two different phenomena. The first is a type of explosion, often referred to as 'BOOMS' (5 letters). This type of explosion is usually caused by a large amount of energy being released in a very short period of time, such as from an atomic bomb or other explosive device. The second phenomenon is known as 'blasts' (6 letters). This type of explosion is usually caused by a sudden release of pressure, such as from a volcanic eruption or other natural disaster. Both types of explosions can cause significant damage and destruction.
