    Aristotle´s Theory of Natural Motion

    Aristotle proposes that objects fall because they seek their natural place, heavy objects fall faster than lighter ones.

  • Galileo Galilei demonstrates that objects of different masses fall at the same rate

    Galileo Galilei demonstrates that objects of different masses fall at the same rate
    neglecting air resistance, he drops balls from the Tower of Pisa

  • Law of Free Fall

    Galileo discovers that the distance traveled by a falling object is proportional to the square of the time elapsed

  • Newton sees an apple falling

    Newton sees an apple falling
    Isaac Newton allegedly observes an apple falling from a tree, inspiring his thoughts on universal gravitation.

  • Newton's Law of Universal Gravitation Newton publishes "Philosophiæ naturalis principia mathematica""

    introduces his law of universal gravitation, explaines that every mass in the universe attracts every other mass.

  • Cavendish experiment

    Cavendish experiment
    Henry Cavendish measures the gravitational constant (G) using a torsion balance, allowing the first calculation of Earth's mass.

  • Einstein's General Theory of Relativity

    Einstein's General Theory of Relativity
    Albert Einstein revolutionizes our understanding of gravity by describing it as a curvature of spacetime rather than a force.

  • Solar Eclipse Confirmation

    Arthur Eddington's expedition confirms Einstein's theory by observing the bending of starlight during a solar eclipse.

  • Pound-Rebka Experiment

    Pound and Glen Rebka confirm gravitational time dilation, proving that gravity affects the passage of time.

  • First Direct Detection of Gravitational Waves

    First Direct Detection of Gravitational Waves
    LIGO and VIRGO detect gravitational waves from two black holes merging, confirming a major prediction of general relativity.

  • First Image of a Black Hole

    First Image of a Black Hole
    The Event Horizon Telescope captures the first image of a black hole's event horizon, providing visual evidence of extreme gravitational effects. Captured in 2017.
