In summary, physicists are exploring the idea of whether mass in other universes can be attracted to mass in our universe. This is one theory that could explain why gravity appears to be weaker than other fundamental forces. It is suggested to read Lisa Randall's book "Warped Passages" for a deeper understanding of this concept.

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.
 

Related to Does Gravity from Other Universes Affect Our Universe?

1. How does gravity work in other universes?

In other universes, the laws of physics may be different than the ones we are familiar with. Therefore, the way gravity works may also be different. Some theories suggest that in other universes, gravity may be weaker or stronger than in our own universe.

2. Can gravity exist without mass in other universes?

The concept of gravity is closely tied to mass, so it is difficult to imagine a universe where gravity exists without mass. However, some theories suggest that in other universes, there may be particles or objects that we are not aware of in our own universe that could create gravitational effects without having mass as we know it.

3. How does the presence of dark matter affect gravity in other universes?

Dark matter is a mysterious substance that is thought to make up a significant portion of the universe. In other universes, the amount of dark matter may be different, which could affect the strength of gravity in those universes. Additionally, some theories suggest that dark matter may behave differently in other universes, leading to different gravitational effects.

4. Is the force of gravity the same in all universes?

As mentioned before, the laws of physics may be different in other universes. Therefore, the force of gravity may also be different. Some theories suggest that in other universes, the force of gravity may be stronger or weaker, or it may even behave differently than in our own universe.

5. Can gravity be manipulated in other universes?

It is currently unknown if gravity can be manipulated in other universes. However, some theories suggest that advanced civilizations in other universes may have the technology or knowledge to manipulate gravity for their own purposes.
