Hubble's role is to observe and collect data on the expansion rate of the universe, which can help scientists understand the properties and effects of dark energy.
Hubble uses its powerful telescope to observe distant galaxies and detect supernovae, or exploding stars, through changes in the brightness of the stars.
Hubble's findings have provided evidence for the existence of dark energy, a mysterious force that is accelerating the expansion of the universe. This has greatly advanced our understanding of the universe and its evolution.
By studying the properties and behavior of exploding stars, Hubble's data can provide insight into the effects of dark energy and how it influences the expansion of the universe.
Hubble's research on dark energy has opened up new avenues for studying the universe and has challenged our current understanding of its composition and evolution. This has sparked further research and will continue to shape our understanding of cosmology in the future.
