Question

One of Einstein's major contributions to the study of physics was his theory of _____. Einstein's theories argued that the knowledge acquired through _____ was not always accurate. In introducing his theories involving _____, Freud tried to explain human behavior and emotion. George Washington Carver developed over 300 industrial uses for _____, helping Southern agriculture flourish.

Answer 1

Albert Einstein's theory of relativity revolutionized physics, and experiments such as the observation of starlight bending around the sun during a solar eclipse, the orbital precession of Mercury, and the detection of gravitational waves, provided empirical evidence supporting his theory.

Step-by-step explanation:

One of Albert Einstein's major contributions to the study of physics was his theory of relativity. Einstein's theories argued that the knowledge acquired through classical mechanics was not always accurate. In particular, Einstein's general theory of relativity made, or allowed us to make, predictions about the outcome of several experiments that had not yet been carried out at the time the theory was first published. Three experiments that verified the predictions of the theory after Einstein proposed it include:

• The observation of the bending of light by gravity during a solar eclipse, which confirmed the prediction that gravity can bend the path of light.
• The precise measurements of the perihelion precession of Mercury's orbit, which could not be accounted for by Newton's laws of gravity alone.
• The detection of gravitational waves, which are ripples in the fabric of spacetime predicted by general relativity, as confirmed by the LIGO and Virgo observatories in 2015.

These experiments firmly established the general theory of relativity as a cornerstone of modern physics, revolutionizing our understanding of space, time, and gravity.
