- Assessing gravitational lensing effects without dark matter models.
Understanding how MOND functions in the realm of dark matter and dark energy provides crucial insights into galaxy formation and evolution.

Current Challenges

Despite its strengths, MOND faces several challenges and limitations, including:
- Inability to explain cosmic microwave background radiation properties.
- Struggles to account for large-scale structure formation in the universe.
- Navigating inconsistencies with observations in the context of gravitational waves.
These challenges of MOND illustrate ongoing debates in dark matter and dark energy research.

Future Research and Innovations

Future research into MOND is focused on reconciling its principles with observations at larger cosmological scales. Innovations may include:
