ok. so basically. The "M" Theory (membrane theory) states that we live in an 11 dimension existance. Now, the only dimensions i know of are these.
We can move in 3 directions. Front to back, side to side. and up and down (jumping).. then, time qualifies as a dimension as Albert Einstein stated. those are the ones i know for sure. i have a feeling gravity would be a dimension too.
Now, the M theory is about how our universe started, and where we came from. But it started off as a theory called THE STRING THEORY. The problem with the string theory was, cosmologists could trace our universe back to the big bang. well, within milliseconds after the big bang occured.
now for those of you guys that dont know, the big bang theory states that our universe started out as an infantecimal speck. a dot tinier than the periods in this blog. and this dot became so infused with hydrogen, and different chemicals, it inevetably collapsed on itself and then exploded.
Now, in the string theory, the SPECK that we started off as was called THE SINGULARITY.[i will refer to the singularty as X]. the main problems with it was, what was before X. time? space? anything? what caused X to collapse. how did it all happen? not one physicist could understand. as time went on, people found several different versions of the string theory. They all had the same basic principles, but all were different.
Before the string theory, there was a theory called supergravity. When the string theory came out, string theorists, and supergravityists couldnt agree on something. the only difference in the string theory and supergravity, the number of dimensions. Supergravity stated there were 11 dimensions. String theorits stated there were 10. as time went on, there were eventually 5 different versions of the string theory. now, think of it this way. for something called THE SINGULARITY, how can there be 5 different versions of what happened? well, somewhere along the line, some physicists incorporated the 11th dimension of supergravity into the string theory.
Once the String Theory had the 11th dimension, all the different versions suddenly all equaled out to the same thing. The Membrane theory.
Now, the membrane theory states that our universe is a proverbial membrane. just a mass floating around. now, with the membrane theory, we could trace back to the big bang, and even figure out HOW it happened.
So the membrane theory starts off with parallell universe. now, one thing scientists had trouble figuring out, why is gravity so weak? it may not seem weak. it keeps us on the ground, keeps everything from floating off. its there. we feel it. but think of it this way. take a small refrigerator magnent. put a paper clip on the table. and hold the magnent over the paperclip. its common sense that the paper clip will come up towards the magnent. proving that even a SMALL magnent has more force on earth than gravity. now what they had to figure out, is why is it so weak? and what they found out, gravity is dispersed through the paralell universes. it starts in the OTHER universe (A) and filters through the 11th dimension to our universe (B)
Now, this 11th dimension, is like a string. its infinately long, but when it comes to width, its smaller than the space between your skin and your clothes. this is where the membranes are.
Ok, so this 11th dimension holds A and B. and the membranes arent stationary. they float around. but according to what they found out, theres not just A and B. theres an infinate amount of universes. the way they put it, Our universe is just a bubble floating around in an OCEAN. and eatch membrane holds a different shape. some are bubbles, some are cylinders, some are donut shaped. whatever... but theres an infinate number.
This had a scientists intrigued. there are so many membranes floating around in the 11th dimension, they are bound to collide. From what they say, each membrane isnt flat, and it isnt really solid. but it ripples. like when you throw a rock in water. so when the clash, its not like a train wreck, but its like trying to put your knuckles together. only certain points touch at certain times. and when they hit, they hit with the force of 1000000000 suns. they pull apart. and whats left. a single point full of energy from both sides. and what happens. A BIG BANG.
So basically what the M Theory states, theres an infinate number of universes, probably eatch with different laws of physics. think of it this way. universes of made of electrons. full of electricity, lightning, darkness. hydrogen universes full of gas and explosions. and there are probably other univereses like ours. they say, there could be univereses JUST like ours. slight differences. could be just like our world today, but you arent there. maybe there are even copies of you. who knows? there has to be other civilizations tho. more advanced. still primitive, floating eyeballs? anything.
so thats the M theory.
