Mars Has Influence on Earth's Oceans and Climate, Repeating Every 2.4M Years
New research suggests a 2.4‑million‑year cycle in Earth’s oceans and climate linked to gravitational interactions with Mars, prompting comparisons to other long-period astronomical influences such as Milankovitch cycles and hypothesized galactic oscillations. Commenters explore how such findings might relate to past extinction events and abrupt climate shifts, while also expressing concern that they could be misused to legitimize astrology and pseudoscience. Others question how strong the causal link really is, emphasizing the need for robust modeling before attributing major climatic changes to Mars’ influence.
Study significance & climate cycles
- One commenter calls the new paper a major recent discovery in climate research.
- It is linked to possible explanations for events like the Younger Dryas and associated extinctions, via long-period astronomical “epicycles” that might stack.
- A linked figure from the Nature paper suggests Earth is near a local maximum of the identified cycle.
Astronomical periodicities & extinction events
- A separate 26-million-year periodicity in mass extinctions is discussed; proposed explanations include the Sun’s motion through the galaxy and speculative dark-matter structures.
- Some treat these periodicity ideas playfully (e.g., “dark forest” aliens periodically resetting biospheres); others tie them to specific past disruptions.
Dark matter, dark energy, and galactic motion
- Extended debate clarifies:
- Dark matter is a hypothesized non-luminous mass interacting via gravity, used to explain rotation curves and lensing.
- Dark energy is a separate concept relating to accelerating cosmic expansion.
- Commenters note that observations constrain only the product of mass and gravitational constant, not each separately.
- Another thread explains the Sun’s oscillation through the galactic plane as a vertical “bobbing” motion, largely decoupled from its orbital period; some question this decoupling, others defend it with analogies (pendulum, local disk gravity).
Astrology, ancient knowledge, and pseudoscience concerns
- Multiple commenters worry the Mars–climate result will be misused to legitimize astrology or esoteric claims.
- Some argue that ancients used astral cycles as practical trackers of Earth cycles (correlation, not causation).
- A linked “Meru Project” talk sparks disagreement: some see rigorous inquiry; others denounce it as religious or numerological “quackery.”
Trust, conspiracy thinking, and institutions
- One view characterizes conspiracy and magical thinking as ego-driven; another counters that they stem more from eroded trust in institutions and pervasive manipulation.
- Suggested remedies include transparency, open debate, and accountability for misinformation.
Skepticism about Mars’ role
- At least one commenter questions whether Mars can exert a meaningful gravitational influence, seeing the article as possibly overstating correlation and causation and calling for reproducible modeling.
Context & references
- Milankovitch cycles are mentioned as established precedent for orbital forcing on climate.
- Several lighthearted references are made to sci-fi works and pop “doomsday” memes.
