String theory is some hard stuff to understand. I once sat in on this grad level physics string theory class just because I was bored one day, and could understand very little of it. I know a decent amount of math, basically through undergrad quantum, but this was some strange stuff. Id be curious to learn more about it, but Im not a physics major so I guess thats going to be difficult.


String theory is an excellent "theory" but is far far away from being experimentally verified. As the enormous depth of maginifaction is beyond a billionth of a billionth of a metre, it is'nt possible to view with our current technology.

The amount of power it would take to probe that deeply into the fabric of the universe, to discover a string directly would literally take all the energy from the our galaxy(milky way) directed onto a single point of manginifaction. So for now, string theories are just interesting theories. To build other thoeries on the basis of these theories is interesting, but we need to have verification of the truth of string theories themselves before we build speculative theories based upon them.

There are a few good cases made that string theories can, in the future be verified indriectly. The fact that it unifies the experimentally valid theories of relativity and quantum mechanics is an interesting observation in itself too.

Well the idea of testing it, is to see what it predicts, then test if that is the case. You can't literally see the strings.

string theory is just the newest brand name of theoretical physics. Add enough variables, enough dimensions, enough degrees of freedom, enough universes and someone can hypothesize anything.

remember, it's impossible to measure something without interacting with it. someone needs to build something that interacts with some other dimension or universe or variable. if you ask some people, they might say "The Bible".

Well we could fathom as the d0 brane that is our universe/focus that therefore any possibility is branched directly from our universe but the universes engendered are in different dimensions than ours and therefore dont interact directly with ours as explicate order all possibilities are existing but they are spread directly FROM our dimension or universe..

The M-split wave therefore reflects and reverberates through eternity..

But because of central focus or otherwise our universe is prime in the connection and production of other universes..

No String theory is unique in one respect. Every other theory of physics since the friggin' Greeks has involved point particles. That is the crux of string theory. The rest you get for free.

Let that sink it. Once you no longer assume point-particles exist gravity *just* appears.

Honestly, the concept of a point is kind of sketchy.  I think that it's more fair to say that physicists have been getting by with a sort of undeveloped concept of what a point actually is and that the theoreticians have been trying really fucking hard to actually further develop that aspect of their various hypotheses.  And, in all honesty, the mathematics that you actually need to do that barely existed (if at all) until pretty well into the Twentieth Century.

Well if a point is the minimal thing than couldnt a point be a particle.. or sub atomic particle.. similar to a granule of sand..being a dot or point of sand for example.

Or like the minimal measurment possible would be a planck length.. So does that mean a planck length is a point? Or maybe its a point extended into a line of minimal measurement..?

I have no idea what you mean by "the minimal thing."  A point is just a neighborhood of some space that satisfies some axioms which amount to the properties of a point, and those depend on the kind of space that you're considering.

Im saying that the minimal measurement possible would be a point..

Can you think of anything smaller than a point?

I'm really not sure what you mean by that.  If by "measurement" you mean the distance between two points then that's not actually a part of the space.  A distance between two points is basically just an image of a pair of points, by some mapping into the real numbers (though I don't, personally, know off of the top of my head whether it has to be into the real numbers or even the complex numbers -- I'm going with what is sort of a sketchy recollection of the property of a topologist's metric).

Well so do you believe there is any perfectly empty space with no matter or particles in it?

I think that is what sone people are terming the vacuum.. but with a vacuum you have a type of force and that is usaully mapped via particles or waves..

Hmm, what about the space in between the rotating sub-atomic particles.. the space within an atom..

Do you think its full?

If so, what is it filled with?

Strings perhaps.. those strings would be loaded!
