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.

What is m-theory?

M-theory is a theoretical framework that aims to unify the five different string theories proposed in the late 20th century. It is a proposed theory of everything that attempts to explain the fundamental nature of our universe.

How does m-theory differ from other theories of everything?

M-theory is unique in that it proposes the existence of eleven dimensions, whereas other theories of everything typically only include four dimensions. Additionally, m-theory incorporates both quantum mechanics and general relativity, while other theories tend to focus on one or the other.

What evidence supports m-theory?

At this time, there is no empirical evidence that directly supports m-theory. However, some of its predictions, such as the existence of multiple universes and the possibility of extra dimensions, have been supported by other theories and observations in physics.

Why is m-theory considered to be a promising theory of everything?

M-theory has the potential to unify all of the fundamental forces and particles in the universe into one cohesive framework. It also offers potential solutions to some of the biggest mysteries in physics, such as the origin of the universe and the nature of black holes.

What are the current challenges and criticisms of m-theory?

One of the main challenges of m-theory is its lack of empirical evidence, making it difficult to test and validate. Additionally, there is still much debate and disagreement among scientists about the validity and feasibility of m-theory. Some also argue that it may be too complex and abstract to ever be fully understood or proven.
