Astronomers can use the shape of arriving gravitational wave signals to calculate how much energy was released when the ... Either way, converging on the true value of the Hubble constant is vital for ...

The issue has come to be known as the "Hubble tension." It arises from the fact that there are two ways to calculate the Hubble constant at the universe's current age, but these methods do not agree.

It arises from the fact that there are two ways to calculate the Hubble constant at the universe's current age, but these methods do not agree. The team behind this research suggests that this ...

It arises from the fact that there are two ways to calculate the Hubble constant at the universe's current age, but these methods ... measure the Hubble constant using distances and redshifts ...

It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different numbers when calculated two different ways, even though those ...

(Credit: NASA, ESA, CSA, STScI) Observatories like the Hubble Telescope ... of the observable universe. Cosmologists use a variety of methods to calculate the age of the universe, building ...

we can get a reading of what the Hubble constant would have been back when the universe began, and then use our knowledge of the laws of physics to functionally fast-forward and find what that ...

We have known for almost a century that the universe is expanding ... The Webb data gave a Hubble constant of 72.6 km/s/Mpc, which was very close to the Hubble Telescope at 72.8 km/s/Mpc.

Then, in 1998, scientists discovered the universe’s rate of expansion is accelerating. In the years since, researchers using the ... who helped calculate the Hubble constant but was not involved ...

the study used observations of distant galaxies and supernovae to independently calculate the modern universe's expansion rate using three separate methods. Like Hubble, Webb's data points to an ...
