Everything we see in the universe, including ourselves, is the result of interactions between these particles. Fundamental forces mean interactions of elementary particles. Four fundamental forces have been identified. They are gravitational force, electromagnetic force, weak nuclear force…
The Great Blue Hole in Belize is an extraordinary marine sinkhole renowned for its unique structure and diverse marine life. This natural wonder features a layer of freshwater at the top, while denser saltwater settles at the bottom, creating two distinct environments due to their density differences. The separation of these layers supports various types…
