The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark ...

One of the big mysteries of the universe is how it's expanding. The phenomenon causing that expansion is known as dark energy — and recently, scientists have started to wonder if its changing.

The expansion of the universe is, in some ways ... Montana as part of The Conversation's Curious Kids series. Nicole Granucci received her B.S. in Physics from UCONN, a M.S. in Science Education ...

But the very existence of dark matter is only ever discussed in the context of an expanding universe, leading some to question whether there are other causes of expansion. A study published in the ...

NASA, ESA, CSA, STScI, Adam G. Riess The Hubble telescope has been measuring the expansion of the universe for three decades. Now, new research from a partnership between the Hubble and the James ...

In recent decades, scientists have also determined that the universe isn’t just expanding—that expansion is accelerating. But this (pretty convincing) hypothesis of an expanding universe comes ...

Birthed from the minds of astronomers Edwin Hubble and Milton Humason, the Hubble constant has long been our closest attempt at understanding the universe’s rate of expansion. However ...

The universe was expanding, and Hubble clocked its expansion rate at 500 kilometers per second per megaparsec, a constant that now bears his name. With the expansion of the universe in hand ...

New research looking at the cosmological constant problem suggests the expansion of the universe could be an illusion. The expansion of the universe could be a mirage, a potentially controversial ...
