Can molecules exist in other dimensions?

Click For Summary
SUMMARY

Molecules, as understood in classical physics, exist within a three-dimensional environment. However, in string theory, which posits additional dimensions, electromagnetic interactions are limited to three spatial dimensions and one time dimension, while gravitational forces may extend into other dimensions. This suggests that while molecules may not exist in the conventional sense in higher dimensions, their gravitational influence could still be recognized. String theory remains speculative and lacks empirical evidence, yet it is a topic of serious consideration among physicists.

PREREQUISITES
  • Understanding of string theory concepts
  • Familiarity with electromagnetic and gravitational forces
  • Knowledge of dimensional analysis in physics
  • Basic principles of atomic structure and forces
NEXT STEPS
  • Research the implications of string theory on molecular existence
  • Study the differences between 1/r² and 1/r³ force laws
  • Explore the role of gravity in higher-dimensional spaces
  • Investigate empirical evidence supporting or refuting string theory
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the implications of higher-dimensional theories on molecular and atomic structures.

I took physics in high school many-many-many moons ago. Mr. Smith taught that molecules can only exist inside a three dimensional environment. Is that true?

It depends on what you mean by "exist". In most string theories that assume several more dimensions, electromagnetic interactions, as well as the strong and weak nuclear forces, are constrained to three spatial dimensions and one time dimension. But the gravitational force may not be. Which would mean that the molecule would "exist" in the other dimensions by virtue of its gravity.

Of course string theory is entirely speculative, with no empirical backing at all, but it is taken seriously by many physicists.
 
Yes. In fact, in 4-dimensional space (4+1 dimensional space-time), even atoms cannot excist, because forces in 4-d space are governed by a 1/r3 law instead of the 1/r2 law you have in 3-d space. The electromagnetic force on the atomic scale becomes so large that the electrons are pulled into the nucleus or sent flying out of orbit.
 
In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
