SUMMARY

String theory posits that gravitational interactions are mediated by gravitons, which are produced as vibration modes of closed bosonic strings. These strings exist in a complex framework that includes branes, which are n-dimensional constructs that can interact with strings. The interaction of strings and branes is fundamental to understanding the mechanisms of gravity within string theory. This discussion highlights the importance of further reading to grasp these advanced concepts.

PREREQUISITES
  • Understanding of string theory fundamentals
  • Familiarity with the concept of gravitons
  • Knowledge of branes in theoretical physics
  • Basic grasp of quantum mechanics
NEXT STEPS
  • Study the role of gravitons in string theory
  • Explore the concept of branes and their interactions with strings
  • Read "The Elegant Universe" by Brian Greene for foundational insights
  • Investigate advanced string theory topics, such as M-theory
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the intricate relationships between string theory and gravitational forces.

ok...I'm a dummy. been doing some novice reading on string theory lately. couple questions: are strings in 'empty space'? and if so, is this how the gravitational pull of a body is exerted on another body...thru the interaction of strings in-between?

thanks.

String theory has a graviton, produced as a vibration mode of a "closed bosonic string". Strings can interact with each other, in fact that is the big subject of introductory string theory. So strings can exchange gravitons, and this would implement gravity a la string theory.

The space strings exist in is complicated by the existence in the theory of branes, like pieces of n-dimensional space for various values of n. Strings not only interact with branes , they can live in branes, or join branes together, and by playing around with these ideas physicsts have come up with huge amount of physical theory.
 
ok...thx. need to do some more reading. got any suggestions? just finished the 'Elegant Universe'.
