11 mar 2024 · Riess holds a Nobel Prize for co-discovering the fact that the universe’s expansion is accelerating, due to a mysterious phenomenon now called “dark energy.” As a crosscheck, an initial Webb observation in 2023 confirmed that Hubble measurements of the expanding universe were accurate.
12 wrz 2023 · We can predict the expansion rate of the universe by observing its baby picture, the cosmic microwave background, and then employing our best model of how it grows up over time to tell us how fast the universe should be expanding today.

19 maj 2022 · Science history will record that the search for the expansion rate of the universe was the great Holy Grail of 20th century cosmology. Without any observational evidence for space expanding, contracting, or standing still, we wouldn't have a clue to whether the universe was coming or going.
After several billion years, the universe has reached its modern state, and it will start contracting in another several billion years. Dark energy corresponds to the force between the branes, allowing for problems, like the flatness and monopole in the previous theories to be fixed.
26 sty 2022 · The universe is not only expanding but accelerating away from us. Now a new theory suggests all this could stop sooner than anyone imagined.
24 maj 2017 · The straight answer is that the universe doesn't expand into anything. There is no space "out there" for it to expand into. What the cosmic expansion does is stretch space itself, as if...
