M-Theory of the Universe: Explaining the Big Bang

[Jives]

I saw a startling new theory on the Creation of the Universe yesterday. For wuite a while now, the Super String theory physicists have been fighting with the 11th Dimensionalists. Unfortunately, neither theory was quite right.

The answer? They got together and everything fit perfectly! 11th dimensional strings!

The thing that confused everyone the most was the weakness of gravity. Think about it: a glass of water on a table is being pull down by the entire gravity of the whole planet Earth. Yet you can lift it easily, overcoming all of Earth's gravity.

Why are atomic forces so strong, (think nuclear explosion) yet gravity is so weak?

The answer seems to be that gravity is very strong, in it's home Universe, it's just weak by the time it gets to us.

This theory supports a bunch, if not an infinite amount of alternate Universes. Check here:

And this also helps:

This is no easy job, of course, and the explanation provided is not intended to be definitive, but offer one view, and be thought provoking. It appeals to string theory, as explained in the previous article.

String theory appeals to 11 Dimensions presently, as opposed to our traditional view of 3D space: up-down, left-right, in-out; or 4D if we include a time dimension.

Originally string theory (from here on, ST) had 10 Dimensions, but this resulted in many string theories, and the introduction of 11th Dimension reduced these all to the same one. This 11th dimension is infinitely long but very, very small across.

In this theory, a membrane stretches across the universe from one side to the other, a giant structure. Oor whole universe is a membrane. This idea might explain the big bang.

Gravity had always been a bit of a mystery - why was it so weak? It may not appear to be, but it is if you think about it. For instance, magnetism is very strong - if you take a tiny magnet, and a small pin, it will drag the pin to it from a fair distance. Yet the entire earth cannot stop us jumping or lifting objects with its weak gravitational force. It doesn't suck us in. Why is it so weak?

To answer this, appeal is made to the 11th dimension. If, in here, there is another membrane which is leaking gravity to our universe, then it can explain our gravity. It is a feint signal emanating from this other universe. So, in order to explain gravity, an appeal to a parallel universe is made, which were traditionally rubbished and avoided, at least, by respectable physicists.

These parallel universes, with their respective membranes, may be completely different - others will have life. If there are an infinity of such universes, then some have said that this means there will be an infinity of universes that contain life (though this is a fallacious argument - for instance if no other combination of constants could logically possibly create life then no other universes will contain life).

So this 11th dimension now sounds very strange - it is full of these other membrane universes; it is a multiverse. HOw can it explain everything - including one of the fundamental questions - the singularity that is said to have led to the Big Bang (which was neither Big nor a Bang, a bit of a misnomer there!)

To do this, we need to think of waves. This 11th dimension is turbulent, with universes moving through it. Sometimes they move apart, other times they collide, crashing into each other like huge waves. Membrane collisions could cause a big bang. The big bang would be the aftermath of the ecounter of the two parallel universes. But how could such a collision create the world that we know, with its stars and galaxies in clumps and clusters?

To do this, we look at the properties of the membrane, and if we drop the assumption that they are flat and perfect, but rather rippled then we can answer the question. Where the two membranes meet, they are not perfectly aligned, but two waves out of sync, and these ripples produce the clumps of matter. Therefore as an explanation of the birth of the universe, this theory seems acceptable.

In fact, we can take the laws of physics back on before the birth of the universe, back before the big bang and through the other side, which means that there was time before the big bang, where changes took place to a different world.

The singularity problem disappears. This radically new suggestion means that Einsteins' missing theory is found, and we have something approximating to a theory of everything. Membrane theory, then, could explain everything.

Of course, if this is the case, then it is a bitter sweet victory; for it means that we are nothing special. Rather, there is an infinity of membranes out there in the multiverse, many rather like ours no doubt, though we do not exist in them (certainly on conventional views of personal identity - that what it takes to be person x at time t, and the same person x at t2). So, big bangs may be occurring all of the time. Our universe co-exists with many others; we are merely one bubble floating in an ocean of other bubbles.

Energy leaking in? Are we also leaking out, then? What happens in universes where the net energy flow is negative?

I dunno..... Every new development in this ongoing saga makes me wonder even more if it's not one step further in the wrong direction, further away from the actual truth of the matter. Though I'm no physicist and can't draft any long, boring hypothesis to defend this position. It's not even a position, really. It's just a feeling I've gotten.

You know what I worry about? That just like a retarded boy with a gun, we might someday have enough knowledge to really screw oursleves up.

For example, the scientists that worked on the first atomic bomb were a little worried that it might start the entire oxygen content of the atmosphere n fire, burning up the planet, but they lit the damn thing off anyway!

What if we discover some kind of tesseract, but end up vaporizing our reality?:-3

I think I will need to run over this a few times. I can just about see a connection. The problem for me is that gravity is supposed to emanate from mass. If mass is the result of unsynchronised membrane ripples, what holds the integrity of the mass in the whole show? If mass produces gravitational energy, it cannot come from a single dimension or universe.

No kidding. I'm a Mathematician and it even makes me dizzy.

it might be M theory altough there are other candidates too.

There are some good resources at wiki about this subject i was just reading them today.

To be honestly personaly a theory switching that often about the number off required dimensions or rather the group of theories with each a different number of dimensions is not that convincing to me.

Fact for sure is our world has 3 dimensions (or 4 if you think time is a dimension)

Perhaps more but proving there is one dimension more is allready questionable altough the dual split expirement might require one more dimension, or perhaps a clever guy (or girl) who can explain this with a new kind of math or physics.

I wonder how the school authorities would react if they knew one of their teachers referred to their charges like this in this derogatory manner .
