Part 06: String Theory

slowdub Says:

Aug 28, 2009 - Is the universe infinite? if it is, then it is as infinite large as it is small, so how can we even begin to say this is the smallest of the small?

juggep80 Says:

Sep 12, 2009 - Theres no number called infinite. Its just a concept like a circle.

ibreakkidslegs Says:

Sep 14, 2009 - by abandoning the notion that spacetime is a continuum.

kingbane2 Says:

Sep 21, 2009 - they are only saying it is the smallest of the small that they currently know of, or have a theory for. and as for the universe being infinite that's not entirely true. the known universe is indeed finite, it's just expanding.

PrinceJimbo01 Says:

Sep 22, 2009 - Its theoretical.

BBZZZZZ Says:

Oct 6, 2009 - Id say its more like it has no center like a fractal, if it doesnt have a center and u say its like a circle then no matter how far I travel in space I will always end up in the place I started, we have to understand that center, start and end are concepts made by us, the same goes for size and others I think.

Oct 10, 2009 - Well that's just the point. Basically, think of the days when man standardized clothing into what's called small, medium, large sizes to create unifomity among soldiers. Standardized clothing was invented. The same can be said about theories. Scientists go out and search for a 'suit' or theory to best describe or 'fit' what they percieve. In this case reaserchers came back with a suit called string thory- it's just a model that seems to work until a better suit is found.

pishdad Says:

Oct 10, 2009 - Relativity was just a model- a model that was incomplete but worked enough to be verified by experimentation. That is the key- Experimentation. Ultimatly if it can't pass the test of experimentation or until then you can consider it to be philosophy or mathematical literature and nothing more! Proof is the ultimate goal throughout science!! Without that it's merely literature.

pishdad Says:

Oct 10, 2009 - Ultimately, slowdub, yours is the ultimate infinite loop- the biggest problem in physics- past, present, future!! Ultimately researchers get tired of that and try to force a 'new' theory down everyones throat. They come back with the newest red suit called string thory!! They merely ignore the obvious- if strings are the ultimate fundamental 'particle' then consists of its' building blocks?!!

MrPerseus2009 Says:

Oct 11, 2009 - Do you not understand there is no beggining, or end there just is existance of time infinite.

pishdad Says:

Oct 11, 2009 - You don't understand the tautology of your own statement. To say that there is not beginning or end but only time infinite is a total contradiction of your very statement!! Ha,ha, ha!! Sorry, I just find that amusing! I'm sorry your statement is not well thought out and is unfortunately irrelevant.

crazycatmanful Says:

Oct 27, 2009 - what mrperseus2009 i think meant was that technically there is no begging or end because time is just a measurement of events and happenings in our perceived world like the night and day measuring the sun setting and rising. its a way to keep track of happenings and planning what happens next since there is no actual "time" that implies that everything happens at one instant time just anoother measurement we percieve granted we wud be lost without it

Shifticek Says:

Oct 29, 2009 - and could you explain how his statement contradicts itself? everyone can say everything is wrong but you need evidence to prove it wrong

pishdad Says:

Oct 29, 2009 - The simplest answer to your quesiton is that there is 'time' is to also say there is a beginning and end because that is what time is- a beginning and an end. That is the very definition of time itself. If there is no beginning and no end then you are no longer speaking about time!!!!! You are speaking about something which you haven't bothered to define!! I hope that answers you quesiton! It should answer your question because it is a total and complete answer to your question!!!!

Slip819 Says:

Oct 30, 2009 - Time or the temporal in physics is just a word that describes intervals of change, it has nothing to do with beginning and end. In relativity it's called spacetime they are non-categorically differentiable, one of the effects of which, in the case of time, is non-simultaneity (which *is* evidenced and used in modern technology namely GPS systems) proving "time" or simply the interval of change an object goes through is utterly relative to each respective object's velocity.

pishdad Says:

Oct 30, 2009 - I respectfully disagree with you. When someone refers to intervals of "change" this implies a start and a stop, hence beginning and end if for nothing more the 'interval' itself. Additionally, you can refer to spacetime as much as you want which proves nothing except the language relativity refers to in respect with time. Since relativity bar far falls short of being a comprehensible explanation of reality it's use of the concept of time is by far the final word.

pishdad Says:

Oct 30, 2009 - I'm aware of the spacetime concept, however I consider this to be a 'fudge' element. A faux pas in physics. It's a seductive concept but I believe it is more of an obstacle to our path of understanding reality than it is a help. Much like Microsoft windows is to computers!!! Lol!! I've said it before, relativity is the MS windows of physics- it works at 'some' level, calculates some stuff, but still full of bugs and incomplete.

pishdad Says:

Oct 30, 2009 - The pendulum hasn't made it full swing yet. When it does I think we're going to find MS windows actually slowed mankinds progress and like wise relativity!!!

LeconsdAnalyse Says:

Oct 31, 2009 - `Time`..`Beginning`..`End`..`Infinite`...these are all terms created by Man.The fact of the matter is, we don`t yet fully understand the absolute scheme of things...whatever that may be.

EtheralDismay91 Says:

Nov 3, 2009 - no beginning and no end is the basis of what infinite is? how is that a not well thought out statement if something is infinite you cant pinpoint its beginning or its end?

pishdad Says:

Nov 3, 2009 - Time is not infinite; it must have defined parameters or it isn't time. To say that something is time infinite is a contradiction within those two words. "Time infinite" is undefined and therefore meaningless.

EtheralDismay91 Says:

Nov 5, 2009 - exactly if its paradoxical remember that at the quantum level everything is unpredictable, if everything is unpredictable at the quantum level, imagine in other dimensions where our laws of physics don't apply?

Nov 7, 2009 - What song is played on the cello around 1:27 ?

italia300 Says:

Nov 12, 2009 - its Bach's first cello suite The first movement - Prelude!

Nov 15, 2009 - but if there's strings are the blank paper of reality then who is dra
