SUMMARY

The discussion centers on the feasibility of traveling between multiverses, highlighting that current multiverse theories, such as inflationary cosmology and quantum many-worlds, do not support the possibility of inter-universal travel. The brane world cosmology suggests that gravity could traverse extra dimensions, potentially allowing movement between braneworlds. However, the consensus is that multiverse concepts remain speculative and unproven, necessitating caution in their interpretation. Overall, there is no established scientific framework that confirms the possibility of multiverse travel.

PREREQUISITES
  • Understanding of multiverse theories, including inflationary cosmology and quantum many-worlds.
  • Familiarity with brane world cosmology and its implications for gravity and dimensions.
  • Knowledge of black hole physics and their theoretical properties.
  • Awareness of the speculative nature of current multiverse hypotheses.
NEXT STEPS
  • Research the implications of brane world cosmology on gravity and dimensional travel.
  • Study the principles of inflationary cosmology and its relation to multiverse theories.
  • Explore the concept of quantum many-worlds and its impact on the understanding of reality.
  • Investigate the scientific community's stance on the existence of multiverses and related theories.
USEFUL FOR

Physicists, cosmologists, and science enthusiasts interested in theoretical physics and the implications of multiverse theories.

Do you believe it's possible to travel between our world within a different multiverse? If so, how do you believe it happens/is possible (e.g. Will we invent specialized machines or are there certain points/places that act as portals?)

I believe before we ask questions like this, we must first master our own universe. We don't even know if the multiverse theory is correct.

Although, it might be possible. albeit unlikely. Black holes are a possibility I suppose, but we would next a ship capable of the conditions.
 
It depends on what you mean by multiverse. there is not one multiverse theory, rather the multiverse is an idea that seems to come out of other theories like inflationary cosmology, brane world cosmologies, quantum many worlds etc.
In the most popular multiverse ideas like inflation and the quantum many worlds it is not possible to travel from one world to other. In brane world cosmologies gravity can move across extra dimension and travel from one braneworld to the other.
I don't know of any multiverse ideas that allow people to travel from one universe to another.
Of course we don't know that there is a multiverse. It may that all the multiverse ideas out there are wrong so one needs to treat there's ideas with caution. but whilst they aren't confirmed science they are not just pure flights of fantasy either but do have some physical basis on modern physical theories that are taken seriously.

Multiverse hypotheses are too speculative at this point to be able to answer questions like this.
