Doubts about the standard model of cosmology are deepening after a new study identified fundamental problems in a recent ...

A cosmological controversy has been reignited over whether observations of supernovae support long-held ideas about the ...

According to our best understanding, the universe is expanding – and is doing so at an accelerating rate. This is believed to be caused by something called the “cosmological constant”, which was first ...

Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the ...

Two weeks ago, when Till Sawala heard the news of a peer-reviewed paper that purported to upend our understanding of the universe, he immediately suspected that something was off. Then again, the ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.

What if one of the biggest assumptions in cosmology is wrong? New research suggests the universe may not be perfectly uniform in every direction, as scientists have long believed. A puzzling mismatch ...

Einstein’s cosmological constant was initially introduced to create a static universe but was later abandoned. Astronomers ...
