Mars could be creating 'giant whirlpools' deep within our planet's oceans

• The gravitational pull Mars exerts on Earth may be strong enough to impact ocean currents.
• The red planet can cause deep-sea currents to change over a 2.4 million-year cycle, a study said.
• The study could help scientists create better climate models of Earth. 

Mars may be 140 million miles away, but its gravitational pull could be impacting Earth's oceans.
