Discussion Overview

The discussion revolves around understanding M-theory, specifically the implications of brane collisions and their relation to the Big Bang. Participants explore the concepts of infinite time, kinetic energy, and the nature of the universe's creation.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the idea that branes have "always" existed and how this relates to the occurrence of collisions that lead to the Big Bang, suggesting a paradox regarding kinetic energy and matter conversion.
  • Another participant reiterates the notion that if branes have always existed, then collisions must have occurred infinitely, raising concerns about the energy available for the creation of the universe.
  • A different viewpoint mentions that a model related to branes was discredited due to incorrect experimental results, suggesting a shift in understanding towards the hot Big Bang model and inflation.
  • One participant expresses confusion about the concepts discussed, indicating that they found the explanations helpful in clarifying their understanding.

Areas of Agreement / Disagreement

Participants express differing views on the validity of M-theory and its implications, with some supporting the idea of brane collisions while others reference discredited models. The discussion remains unresolved regarding the implications of kinetic energy and the nature of the universe's creation.

Contextual Notes

There are unresolved assumptions regarding the nature of branes, the mechanics of collisions, and the implications for energy conservation in the context of M-theory and cosmology.

howdy felles. I have been trying to make sense of m-theory for a while now, but I cannot seem to get past a problem that I see in it, and the thing is I don't know if I am making a mistake in there somewhere or not.
anyways here is where I see the problem!
It is said that our universe is within a big mem-brain. and there is more than 1.

And as a result of their collision there is a massive explosion (Big Bang), they also say that there was no begining, which to me means that infinite time has ellapesd science the last collision. If this thery is right how come there still was a collision some 15billion yrs ago?
I mean there must have been a loss of knetic energy (not exactly loss, but conversion, from knetic to matter).
can someone help me clear this up please.
cheers "bayan"

The idea is that the branes have "always" existed, but the collisions occur in time, every now and then, and one of them caused the formation of our world.

exactly my point. if they have existed forever then that means these collisions have occurred forever too. since the creation of our universe is a result of this collision this leads me to think that there has been less knetic energy in the branes (since some energy was converted to matter!) how is it that there was a bang to creat our universe? (there was less and less knetic energy in branes after each collision.) or is there something that I still don't get?

That model was discredited by giving wrong experimental result by Andrei Linde some time ago. The current model of cosmology continue based in the old hot Big bang model + inflation.

Cosmological strings have failed. In words of specialists Krauss.

String theory has been a failure
 
No wonder why it made no sense to me. Well thanks for clearing that up mate.

cheers
