Measuring the Effects of Dark Energy on Bound Objects: An Experimental Study

Click For Summary
SUMMARY

This discussion centers on the misconception that dark energy affects the movement of bound objects in everyday life. Participants clarify that dark energy, while influential on cosmic scales, does not exert a measurable force on smaller, bound systems, akin to an ant pushing a house. The conversation emphasizes that any attempts to modify force equations to include dark energy for small objects are fundamentally flawed, as dark energy does not contribute to the forces acting on them. No experimental evidence supports the idea that dark energy influences the net force between two objects in a laboratory setting.

PREREQUISITES
  • Understanding of classical mechanics and force equations
  • Familiarity with the concept of dark energy in cosmology
  • Knowledge of experimental physics methodologies
  • Basic grasp of gravitational interactions between bound objects
NEXT STEPS
  • Research the role of dark energy in cosmic expansion and its implications for astrophysics
  • Explore experimental physics techniques for measuring forces between small objects
  • Study the principles of gravitational binding and how they relate to dark energy
  • Investigate existing literature on experiments involving dark energy and its effects
USEFUL FOR

Physicists, students of cosmology, and researchers interested in the implications of dark energy on physical systems and experimental methodologies in physics.

I’m thinking about modifying some force related equations to include dark energy in them for an essay on physics. My reasoning is that if it can separate galaxies the objects in our day to day lives must also have a small tendency to move apart. To do so, I have to dispose of an already done experiment on this matter. As there been any experiments regarding the measurement of dark energy between two objects ?

What do you mean? In laboratory conditions?
 
Suppose you did an experiment, and measured a net force between two objects. How would you know what component of that force was due to dark energy?

That is a common misconception, but it's like an ant pushing on a house. The ant just doesn't move the house. At all. Period. Likewise, dark energy does not cause bound objects to move apart.

If a person attempts to move a heavy object, he will have to exert less force if an ant is pushing it than if it’s not. Therefore, if the ant represents dark energy, what’s the force that the person has to exert on the object? That is what I would like to know, if someone has already done an experiment regarding that matter.
