You know...I'm sorry, but string theory feels like a bunch of bullshit used to try and make flawed theories work.

[Anonymous No.4637778]

Yes?
That's exactly what it is.
It's a theory, but right now it's what most scientists think is the best.
You are welcome to submit your ideas. If it works, and you can the idea out there, you will likely uncover several now unknown laws of physics and reality.

I would encourage the people of /sci/ to take a look at m-theory or superstring theory...as string theory is from the 60's and of course sounds retarded...the basic fundamental idea of the string vs. the particle, I prefer the string

[Anonymous No.4637811]

What do you not like about it? You make something better

The 11 dimensional worldsheet encodes every standard model fermion/boson field with a CFT

Particles are given dimensionality so we can explain properties like intrinsic angular momentum and interference

Extra dimensions are needed to incorporate a model of gravity that gives actual results when plugged into a partition function

Superstrings and branes are encoded on a hologram on the worldsheet so everything is just fluctuations in a background metric

It's the most mathematically elegant and simplest shit imaginable like nature always is so Occam's Razor faggots

It also fits every prediction to date and the crap that it does predict we haven't observed yet because we don't have enough money to build particle accelerators bigger than the LHC

So fuck you OP I bet you're the same whiny little faggot who just created that other String Theory thread because babby can't understand how photon polarization works and appreciate global symmetries of space-time which have PHYSICAL MEANING AS OPPOSED TO MATHEMATICAL BULLSHIT

Thank you

Congratulations. Every scientific theory is like this! Each one outdates the last, tells us more about everything, but still fails to explain everything. It has always happened this way and will continue to happen this way, otherwise we'd already be "done" now with this whole life stuff.

How does String theory describe wave-particle duality? Wave function collapse?

[Anonymous No.4637912]

>>4637902
Strings are fluctuations and the harmonics of a background field (imagine a ripple tank), they can spread out and self-interfere just like a wavefunction does. The move just like in quantum field theory taking the path of least action. With string theory though, when you take a continuum limit to a 1 dimensional quantum theory you get a wave function with a pilot wave because of the structure of the background field, eg Bohmian mechanics (inb4 massive /sci/ butthurt because Bohmian mechanics is bullshit pseudoscience and implies FTL, hidden variables, etc. You're all massive cunts who don't understand what a global [space-time] hidden variable is.)

String theory isn't a theory. It cannot be tested. It's essentially a religious assertion, not a theory.

I guess you don't really know any string theory, since none of those statements really makes any sense, maybe excepting the part about extra dimensions. I do however agree that string theory is the best proposal thus far and before calling it bullshit you need to suggest something better. For example, LQG still cannot really prove that it even reproduces classical gravity, and has made no real testable predictions, and also offers no guidance towards unification. There is really no serious contender as a theory of everything other than string theory, and if people doesn't like that they are free to invent a working one themselves.

>I guess you don't really know any string theory, since none of those statements really makes any sense
What are you talking about? Are you fucking kidding me? I don't think you know any string theory son, or you're trolling.

>The 11 dimensional worldsheet encodes every standard model fermion/boson field with a CFT
The Neveu-Schwarz/Ramond sectors describe all standard model fermionic fields in one representation of a N=1 conformal field theory. There isn't any games. It isn't a fakeout. There isn't "coupling" or "parameters" or shit like that.

>Particles are given dimensionality so we can explain properties like intrinsic angular momentum and interference
This is as clear as possible. Do you not know what spin is? In string theory the strings actually have REAL angular momentum, it isn't part of a dimensionless state vector in Hilbert space. I swear, I feel like I am talking with 12 year olds.

>Superstrings and branes are encoded on a hologram on the worldsheet so everything is just fluctuations in a background metric
Essence of the stringy AdS/CFT - you don't know string theory if you don't know holography.

>It also fits every prediction to date and the crap that it does predict we haven't observed yet because we don't have enough money to build particle accelerators bigger than the LHC
We don't have high enough luminosities to detect shit like extra dimensions and superpartners. Is that clearer?

They aren't made out of anything. They are fundamental.

The philosophy we have right now says they fluctuated into existence >> www.youtube.com/watch?v=7ImvlS8PLIo

[Anonymous No.4638131]

>>4638104
That's weird because that guy is talking about quantum vacuum fluctuations, if I recall that video I saw some time ago. Also, he is a critic of string theory, so how does his video support it?

Saying "strings are fundamental" reminds me of 17th century philosphy, like Leibniz saying monads are fundamental, they aren't made of anything or divisible. It just sounds more like philosophy than experiment-based science.

String theory adapts the same concept. It's either quantum fluctuations, time translation invariance did not exist pre big bang, or a mathematical universe in which all possible universes always existed. That's our current philosophical outing.

>Saying "strings are fundamental" reminds me of 17th century philosphy
Well, there needs to be a fundamental level somewhere, else matter isn't discrete and the observational status of quantum mechanics is falsified. If you disagree with this concept, you disagree with modern physics. Physics advances gradually and builds upon earlier understanding. String theory has many theoretical pieces, yes, but it is still science. It is the closest we will get to a picture of reality that we will never really see.

>they aren't made of anything or divisible
Quantum field theory models particles as 0 dimensional fluctuations (delta functions) on fields of infinite harmonic oscillators, which works as an approximation. M-theory extends these fields to a topological background space-time, the conformal worldsheet, with holography and gives dimensionality to the particles.
