So,,,, Time is speeding up faster than we thought Too, Right? :thinking:

"This surprising finding may be an important clue to understanding those mysterious parts of the universe that make up 95 percent of everything and don't emit light, such as dark energy, dark matter and dark radiation," study leader Adam Riess, an astrophysicist at the Space Telescope Science Institute and Johns Hopkins University in Baltimore, said in a statement.
Riess — who shared the 2011 Nobel Prize in physics for the discovery that the universe's expansion is accelerating — and his colleagues used NASA's Hubble Space Telescope to study 2,400 Cepheid stars and 300 Type Ia supernovas
These are two different types of "cosmic yardsticks" that allow scientists to measure distances across the universe. Cepheids pulse at rates that are related to their true brightness, and Type Ia supernovas — powerful explosions that mark the deaths of massive stars — blaze up with consistent luminosity.
This work allowed the team to determine the distances to the 300 supernovas, which lie in a number of different galaxies. Then, the researchers compared these figures to the expansion of space, which was calculated by measuring how light from faraway galaxies stretches as it moves away from Earth, to determine how fast the universe is expanding — a value known as the Hubble constant, after famed American astronomer Edwin Hubble.
The new, unprecedentedly precise value for the Hubble constant comes out to 45.5 miles (73.2 kilometers) per second per megaparsec. (One megaparsec is equivalent to 3.26 million light-years.) Therefore, the distance between cosmic objects should double 9.8 billion years from now, the researchers said.
The new figure is 5 to 9 percent higher than previous estimates of the Hubble constant, which relied on measurements of the cosmic microwave background radiation — the light left over from the Big Bang that created the universe 13.8 billion years ago.
