SUMMARY

The discussion centers on the hypothesis that gravity from other universes may influence our universe, particularly in the context of the multiverse theory. Physicists are exploring why gravity is significantly weaker than the other fundamental forces, proposing that its apparent weakness may be due to its ability to interact across universes. This concept suggests that if gravitational forces from other universes attract mass in our universe, observable deflections should occur. Lisa Randall's book, "Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions," is recommended for further reading on this topic.

PREREQUISITES
  • Understanding of multiverse theory
  • Basic knowledge of fundamental forces: electromagnetic, strong, and weak forces
  • Familiarity with gravitational theory
  • Awareness of theoretical physics literature
NEXT STEPS
  • Read "Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions" by Lisa Randall
  • Research the implications of multiverse interactions on gravitational forces
  • Explore current theories explaining the weakness of gravity compared to other forces
  • Investigate observable phenomena related to gravitational deflection in astrophysics
USEFUL FOR

This discussion is beneficial for theoretical physicists, cosmologists, and anyone interested in the implications of multiverse theories on gravitational interactions.

In the hypothetical multiverse, is it possible for mass in other universes to be attracted to mass in our universe?
 
Space news on Phys.org
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.
