Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
The Hubble tension is one of the biggest mysteries in cosmology. It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different ...
It appears to be expanding faster today than it did in the past There is something unexpected happening in the universe, Nasa’s most powerful ever telescope shows Skip to main content
Hubble, assisted by Milton L. Humason, observed the magnitude of the redshift in many galaxies and published a paper in 1929 that showed the universe is expanding. The Hooker's reign of three decades as the largest telescope came to an end when the Caltech -Carnegie consortium completed its 200-inch (5.1 m) Hale Telescope at Palomar Observatory ...
The Hubble law implies that the universe is expanding. [11] A decade before, the American astronomer Vesto Slipher had provided the first evidence that the light from many of these nebulae was strongly red-shifted, indicative of high recession velocities. [12] [13]
As the universe expands and the matter in it thins, the gravitational attraction decreases (since it is proportional to the density), while the cosmological repulsion increases. Thus, the ultimate fate of the ΛCDM universe is a near-vacuum expanding at an ever-increasing rate under the influence of the cosmological constant.
The mystery phenomenon of why the universe is expanding is known to cosmologists as "dark energy." ... "One possible explanation for the Hubble tension would be if there was something missing in ...
Thus, an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant. This results in a larger light-travel time, larger distance and fainter supernovae, which corresponds to the actual observations.
