Gravitational coupling between planets can change ocean currents and climate.
More than 65 million years of geological data indicate regular changes in deep-sea currents on Earth every 2.4 million years. This is due to the gravitational interaction between the Earth and Mars, which occurs due to their orbital motion.
This was reported by Earth publication.
Deep-water currents on Earth alternate between a strong and a weak phase, which in turn affects the accumulation of sedimentary rocks on the ocean floor. As currents become stronger, they wash away these rocks. New research shows that cyclical changes in currents may be related to the gravitational interaction between Earth and Mars.
Scientists believe that the resonance between the gravitational fields of the planets changes the eccentricity of their orbits, that is, the degree of deviation from a circular trajectory. This affects the Earth's orbit, in particular,…
