Quantum particles expand space?

Click For Summary
SUMMARY

The discussion centers on the concept of quantum particles exerting forces on spacetime, specifically when placed in a confined space such as a cylinder with a movable piston. It concludes that while quantum particles in their ground state may exert an outward force on the piston, spacetime itself cannot be directly influenced by such forces. However, it is established that pressure from quantum particles can affect the curvature of spacetime, suggesting a complex interaction between quantum mechanics and general relativity.

PREREQUISITES
  • Quantum mechanics fundamentals
  • General relativity principles
  • Understanding of pressure and curvature in physics
  • Basic knowledge of quantum states and their implications
NEXT STEPS
  • Explore the relationship between quantum mechanics and general relativity
  • Research the effects of pressure on spacetime curvature
  • Study the implications of quantum particles in confined spaces
  • Investigate the concept of vacuum energy and its effects on spacetime
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the intersection of quantum mechanics and general relativity.

If we put a quantum particle in it's ground state in a cylinder with a movable piston there is an outward force on the piston? If we now put a quantum particle in the universe is there an outward force on space time however small?

Thanks for any help!

Space isn't a thing that you can exert a force on. But pressure does affect the curvature of space.
