Adam Riess, awarded the Nobel Prize in Physics at just 41, made pivotal discoveries regarding the accelerating expansion of the universe. His meticulous measurements in 1998 unveiled a surprising correlation: galaxies further from Earth recede faster, implying an unknown force, later termed dark energy. This hypothetical energy, pervading space, seemingly drives galaxies apart as it accumulates. Recently, however, Riess has expressed doubts about the dark energy theory, prompting re-examinations of his findings and stirring discussions about alternative explanations for cosmic expansion.
Riess's journey into the world of cosmic expansion began with groundbreaking calculations that, upon revelation, introduced the theory of dark energy as a force driving this phenomenon.
Though Riess once believed in the theory of dark energy, he is now grappling with doubts that urge consideration of alternative explanations for the universe's unexpected acceleration.
