Expanding Universe: Big Bang & Beyond

Click For Summary
SUMMARY

The discussion centers on the concept of space expansion following the Big Bang and addresses a common misconception regarding the expansion of atoms, stars, and galaxies. It is clarified that bound systems, such as atoms, are not affected by the expansion of space. The conversation references a previous thread that provides further insights into the mechanics of cosmic expansion, emphasizing the distinction between bound systems and the universe's overall expansion.

PREREQUISITES
  • Understanding of the Big Bang theory
  • Familiarity with the concept of cosmic expansion
  • Knowledge of atomic structure and binding forces
  • Basic grasp of astrophysics terminology
NEXT STEPS
  • Read the previous thread on cosmic expansion at Physics Forums
  • Study the implications of general relativity on cosmic structures
  • Explore the concept of dark energy and its role in universe expansion
  • Investigate the effects of gravitational binding on celestial bodies
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in understanding the dynamics of the universe and the implications of cosmic expansion.

Hi all,
After the 'big bang' it is said that space is expanding. Atom is almost 99% space then why are they not expanding, same can go with all the stars and galaxies and all stuffs.
Hope this is not sounding crazy. If so pls forgive me.
Cheers.
