    Study Notes

    Game Scenario

    • Appu, Sarita, and Ameena have constructed a guessing game.
    • In the game, Ameena asks Sara to think of a number.
    • Ameena declares that the number Sara had thought of is 7.
    • Appu asks Balu to think of a number.
    • Appu immediately tells the number thought by Balu, which is 27.

    Gravitational Waves

    • The concept of gravitational waves was first proposed by Henri Poincaré.
    • Albert Einstein predicted the existence of gravitational waves in 1915.
    • Gravitational waves transport energy through space.
    • Newton's law of universal gravitation does not provide for the existence of gravitational waves because it does not account for the dynamic nature of gravity.
    • Gravitational waves propagate at the speed of light.
