The expansion of the Universe is not constant. Recent measurements have shown that the rate of the Universe's expansion is increasing. The evidence for this area of physics comes from observations ...

Curious Kids is a series for children of all ages ... Another way to think about the universe’s expansion is by thinking about how other galaxies are moving away from our galaxy, the Milky ...

The cosmic superstructure Quipu is more than 13,000 times the length of the Milky Way, and its mass is 200 quadrillion times ...

Previously, physicists had assumed that the attractive force of gravity would slow down the expansion of the universe over time. But when two independent teams tried to measure the rate of ...

Since the universe is still expanding, with each passing year a galaxy is a bit more distant, and that means its redshift should become slightly larger. In other words, cosmic expansion means that ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

Now, results provide even stronger support to the faster rate of expansion. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster ...

Determining the expansion rate of the universe—known as the Hubble constant—has been a major scientific pursuit ever since 1929, when Edwin Hubble first discovered that the universe was expanding.
