SUMMARY

The discussion centers on the concept of atomic structure, specifically addressing the space between electrons and the nucleus. Participants confirm that this space is predominantly empty, likening the scale of an atom to the Grand Canyon, where the nucleus is a small stone at the bottom. Dr. Gregory Greenman, a physicist, emphasizes that at a fundamental level, the vast majority of atomic space is indeed void, reinforcing the idea that the universe is largely composed of vacuum.

PREREQUISITES
  • Understanding of atomic structure and components, including electrons and nuclei.
  • Familiarity with basic physics concepts related to matter and vacuum.
  • Knowledge of scale and proportion in scientific contexts.
  • Awareness of fundamental physics principles regarding space and emptiness.
NEXT STEPS
  • Research the implications of vacuum in quantum physics.
  • Explore atomic models, particularly the Bohr model and quantum mechanical model.
  • Learn about the concept of empty space in cosmology and its significance in the universe.
  • Investigate the role of vacuum in particle physics and its effects on atomic interactions.
USEFUL FOR

Students of physics, educators in atomic theory, and anyone interested in the fundamental nature of matter and the universe will benefit from this discussion.

In the atom between the electron in the orbit and the nucleus what is present?
Is it vacuum? Well if it is so then the entire universe can be assumed to be made of vacuum.

i.mehrzad,

YOU GOT IT!

The VAST majority of space is EMPTY!

There's an old adage that if a single atom were as big as the Grand Canyon; then the
nucleus would be a single small stone at the bottom.

Yes - at the finest level - space is mostly EMPTY.
