Since the late 1990s, astrophysics has grappled with the mysterious presence of dark energy, identified as fundamentally distinct from matter and radiation. This came to light after measurements of the Universe's expansion rate indicated around 70% of its content is this unknown energy, driving cosmic expansion for six billion years. Alan Finkel challenges the necessity of dark energy, suggesting it might instead stem from momentum leftover from the Big Bang. This inquiry prompts a reevaluation of our understanding of the expanding Universe and its foundational principles rooted in Einstein's General Relativity.
The late 1990s revealed a shocking conclusion that while 30% of the Universe is matter, about 70% behaves like a new form of energy known as dark energy.
Alan Finkel raises a profound question about dark energy's existence, urging exploration of whether it truly drives the universeâs expansion or if remnants of the Big Bang are at play.
