Discussion Overview

The discussion revolves around the concept of gravity in the context of a hypothetical multiverse and whether mass from other universes could exert gravitational influence on mass in our universe. The scope includes theoretical implications and speculative reasoning regarding fundamental forces.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants propose that in a multiverse scenario, mass from other universes could potentially attract mass in our universe.
  • Others argue that this idea could help explain why gravity appears weaker than the other fundamental forces, suggesting that gravity might be able to traverse between universes.
  • A participant recommends literature on the topic, specifically mentioning Lisa Randall's work on hidden dimensions.
  • One participant questions the implications of such attraction, suggesting that if it were true, observable deflections in our universe should occur.

Areas of Agreement / Disagreement

Participants express differing views on the possibility and implications of gravitational interactions between universes, indicating that the discussion remains unresolved with multiple competing ideas.

Contextual Notes

The discussion includes speculative claims about the nature of gravity and its interactions, which depend on the definitions of universes and forces involved. There are unresolved assumptions regarding the mechanisms of attraction and observable consequences.

In the hypothetical multiverse, is it possible for mass in other universes to be attracted to mass in our universe?

That's the idea. Physicists are trying to explain why gravity is so much weaker than the other three fundamental forces (electromagnetic-, strong- and weak force). One theory is that gravity only appears to be weaker since it can move between universes, whereas the three other forces cannot.
 
I recommend reading Lisa Randall's Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions.

if it attracts mass in our universe, then we should see the deflection in our universe.
