Discussion Overview

The discussion revolves around the concept of alternate universes and their potential interactions, particularly through the lens of string theory and brane theory. Participants explore the implications of brane collisions and the nature of universes existing in proximity to one another, questioning the mechanisms that might prevent such collisions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that string theory posits branes that can collide, potentially leading to the creation of universes, but questions why such collisions do not occur frequently.
  • Another participant raises the idea that the absence of an atmosphere might allow branes to collide without any slowing mechanism, implying that such events could be happening without observation.
  • A different viewpoint emphasizes that brane theory is not universally accepted within the string theory framework, and questions the lack of a solid explanation for why universes do not collide if they exist on separate branes.
  • One participant speculates that if branes could collide once, there might be nothing preventing future collisions, raising concerns about the implications of such events for our universe.

Areas of Agreement / Disagreement

Participants express differing views on the validity and implications of brane theory, with no consensus on whether brane collisions are a plausible occurrence or how they might affect our universe.

Contextual Notes

Participants acknowledge the theoretical nature of string and brane theories, highlighting the speculative aspects of their claims and the lack of empirical evidence regarding brane collisions.

Before i start writing this forum if your reading this and u notice that i said something incorrectley please tell me so. According to string theory strings can strech out into branes which make up universes. String theory also says that the big bang got its energy from when two branes banged into each other. But if we have other universes right next to us in another dimension, what stops them from banging into us or surrounding universes all the time?

you mean that there is no atmosphere to slow the branes before they collide?

thing is, we can't say that this isn't happening every day, or second, have you ever seen the creation of a universe?
 
In short: Brane theory is only one tribe in the string theory family. Brane collision is not a universally held theory. Also, both string and brane theory are primarily theoretical constructs that "could" explain things. I don't believe that there is a good theory within Brane Theory to explain why other universes are not colliding into our own other than that it is on another Brane which is not on a collision course.

well if there is an atmosphere or somthing to stop 2 branes from colliding they obviousley found someway to break through that froce or there would have been no energy for the creation of the universe, and what I am getting at is that if this could have happened once, what's to stopping it from happening again, why hasnt it happened again, if it did there would have been a new big bang and who knows what would have happened to us.
