# String Theory, the singularity and photons

Hey all, first post here. I had the opportunity recently to ask Steven Weinberg a question that the physics professors at my university didn't have an answer to. In short, Weinberg said he couldn't understand where I was going with my question. My heart broke as I obviously wasn't able to convey what I meant.

So, I have come here hoping that someone could point out an error in my question/thought experiment. I have had this question for over twelve years now despite reading just about every book by Hawking, Susskind, Kaku, Greene and Weinberg.

I recently created this video to illustrate the entirety of the question.

Here is my general assumption:
Strings are bound to a certain location and are not "free floating." As matter travels through space, strings vibrate and transfer the vibration to another string. Basically, the strings that formulate the particles of your body are different now then the ones that made up your body when reading the beginning of this sentence. Since we are traveling through space and are no longer at the previous location in space time, the strings have changed.

Thanks for any input you can provide.

This is just an opinion, to my understanding, strings are vibrating strings of energy and energy can be borrowed in the form of virtual pair sepration and particles can be represented by strings, so virtual strings, should react in the same way as virtual particles per Hawking Radiation. You may want to ask, are strings derived from an energy gradient developed across virtual string pairs by the energy of a true vacuum, and an external or internal source. May be the singularities ( of the B.B, and the Black holes) are the connection.

What you draw is a 1D radial picture. Not every photon follows strictly only the radial direction. Most of the stuff has an angular momentum and bypass the black hole center. So no special damage is done to the "last" string, in my opinion.

In addition, there is no energy conservation law in a curved space. I am not good at it but I am not sure what energy exchange could be between the stuff inside the black hole.
