M Theory & Quantum Mechanics vs. SETI

Click For Summary
SUMMARY

This discussion centers on the relationship between M Theory, quantum mechanics, and the search for extraterrestrial intelligence (SETI). It posits that if M Theory's hypothesis of extra dimensions is accurate, then subatomic particles may serve as conduits for communication from advanced civilizations across parallel universes. The conversation highlights the implications of infinite parallel universes, suggesting that if they exist, the likelihood of advanced intelligent life communicating through particles is significant. However, the counterargument emphasizes that if such communications were occurring, our universe would be inundated with particles from these civilizations.

PREREQUISITES
  • Understanding of M Theory and its implications on extra dimensions
  • Basic knowledge of quantum mechanics, particularly virtual particles and the uncertainty principle
  • Familiarity with the concept of parallel universes
  • Awareness of current SETI methodologies and challenges
NEXT STEPS
  • Research the implications of M Theory on quantum mechanics and gravity
  • Explore the uncertainty principle and its role in quantum fluctuations
  • Investigate current SETI techniques and their effectiveness in detecting extraterrestrial signals
  • Study theories on parallel universes and their potential impact on our understanding of reality
USEFUL FOR

Physicists, cosmologists, and enthusiasts of theoretical physics and extraterrestrial life research will benefit from this discussion, particularly those interested in the intersections of quantum mechanics, M Theory, and SETI.

Watched an episode of Brian Greenes NOVA "The Fabric of the Universe" for the 300th time and an episode of "The Universe" about M Theory and Parallel Universes. A thought/question popped into my head based on my uneducated understanding of these concepts (I was an Econ Major).

* Quantum mechanics tells us that subatomic particles constantly pop in and out of our existence and exist in multiple places at the same time.

Question - Do I understand correctly that M Theory hypothesizes that extra dimensions explain this? That the particles are simply traveling between these dimensions in the same way it tries to explain the weakness of gravity?

My Point - If an infinite number of parallel universes actually exist then the existence of enormously advanced intelligent life is certain. Some of them would have to be sending us communications (every scenario must exist somewhere in infinity). The most obvious place to look for a message is in the stuff we share with them, particles... Right? So if that version of M Theory is accurate (I realize that's a big if) then there must be messages buried somewhere in subatomic particles and we simply have not advanced enough to discover them yet. On the flip side... if there are no messages then that form of M Theory is impossible.

Either way I feel like we have a better chance of discovery there (regardless of how improbable infinite connected universes may be) vs. using telescopes hoping to stumble on another inteligent life form that happens to use light waves to communicate the same way we do and is located within 50 thousand light years of Earth where they could possibly see (using light waves) that our planet was developing intelligent life.

I am sure that almost anyone who frequents this site is capable of shooting this idea down with a pellet gun but I would be interested in knowing.

No, those 'virtual particle vacuum fluctuations' are caused by the uncertainty principal.

If there were infinite parallel universes and they all could send particles to our universe then we would be flooded by infinite amounts of particles from infinite intelligent civilizations!

Place would be a mess heh.
