Study Notes
Gravity
- Gravity is the weakest fundamental interaction.
- Gravity has no significant influence at the quantum scale.
- Gravity gives physical objects on Earth weight.
- Gravity determines the motion of stars and galaxies.
- Gravity influences the biological function of circadian rhythms.
Gravitational Waves
- The concept of gravitational waves was first proposed by Albert Einstein.
- Albert Einstein predicted the existence of gravitational waves in 1915.
- Gravitational waves transport energy in the form of ripples in spacetime.
- Newton's law of universal gravitation does not account for the existence of gravitational waves because it is a linear theory and does not take into account the curvature of spacetime.
- Albert Einstein initially refused to accept the concept of gravitational waves, despite predicting them, due to his doubts about the validity of his own theory.
