Dark Energy Could Rip the Universe Apart - SciShow News

The video explores theories about the end of the universe, focusing on the Big Freeze and the role of dark energy. It discusses how dark energy, which constitutes about 70% of the universe, accelerates its expansion. Standard candles, like type 1a supernovas, have been used to measure this expansion, but they have limitations. New research suggests quasars could serve as better standard candles, revealing that dark energy might be increasing over time. This could lead to a Big Rip scenario, where dark energy tears apart the universe. However, these findings need further confirmation.

What new standard candle did the astronomers propose, and what is its significance?

How do quasars differ from type 1a supernovae in terms of brightness and distance measurement?

What implications do the recent findings about dark energy have for the future of the universe?
