The Universe is expanding – but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate – referred to as the Hubble’s constant, or H0 – based on the echo of ...

CHICAGO (CBS) -- It was 95 years ago that astronomer and University of Chicago alumnus Edwin Hubble made the discoveries that proved the universe is expanding—but the question of just how fast the ...

Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to touch up the cosmological model. "It's like ...

A striking reality faces modern cosmology: two of the most advanced telescopes ever built now agree on a result that the standard cosmological model cannot explain. Webb’s confirmation of the Hubble ...

How fast is the universe expanding? One might assume scientists long ago settled this basic question, first explored nearly a century ago by Edwin Hubble. But right now the answer depends on who you ...

Vesto Slipher first observed that galaxies are moving away from us. Edwin Hubble later showed a relationship between galaxy distance and speed. Hubble's work relied heavily on Slipher's earlier data.

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent study has calibrated the best cosmic yardsticks to ...
