Why have we not been able to explore the ocean at greater depths?
Last night I watched a show on the Marianas Trench. It got me wondering why we haven’t been able to advance with our technology and send men to explore greater depths of the ocean? This was the deepest that men have ever travelled down into the sea. (7 miles down.) Recorded in 1960. If we can send men into outer space, then why are we not trying to send men down to explore greater depths or our ocean?
