Unveiling the Universe’s Mystery: The Groundbreaking Discovery of an Accelerating Expansion

Jul 31, 2023 | Science and Technology

In 1984, astronomer Robert Kirshner made a groundbreaking discovery about the expansion of the universe. He found that distant supernovae were fainter than expected, suggesting that the universe is not only expanding but also accelerating in its expansion. This unexpected result has since been confirmed by various other measurements and is attributed to a mysterious force called dark energy, which is thought to make up about 68% of the total energy in the universe. The discovery of the accelerating universe won the 2011 Nobel Prize in Physics, shedding light on one of the biggest mysteries of our cosmos.
