Big Bang Theory

Researchers confirmed that the distant galaxies discovered by the James Webb Space Telescope are, indeed, perfectly compatible with our modern understanding of cosmology.

The latest book from All About Space editor Gemma Lavender is 'The Short Story of the Universe.' It rounds up our complicated cosmic history in an engaging guide.

Physicists have measured no changes in time or space for any of the fundamental constants of nature.

We don't really know how the universe was created, though most astrophysicists believe it started with the Big Bang.

A new interactive map of the cosmos allows users to journey from our galaxy to the most distant sources of light that existed just after the Big Bang.

NASA's newest space telescope has left scientists seeing distant stars — and galaxies.

Researchers have proposed what's perhaps the most exotic explanation to date for the source of the universe's seed magnetic field: cosmic strings.

New research highlights a troubling problem with the concept of a cyclical universe that experiences infinite expansion and contraction, known as 'bouncing universe' models.

The "most comprehensive studies" of the Higgs boson conducted to date reveal that the particle behaves as expected and could help unlock some of the greatest mysteries of physics.

The Large Hadron Collider (LHC) is back with more powerful collisions than ever before and scientists are thrilled to see what they can learn.

A new simulation maps the first few seconds after the Big Bang, focusing on what scientists call the intergalactic medium, or the gas and dust between galaxies.

The collider cost $730 million and is many decades in the making

At that temperature, the Linac Coherent Light Source (LCLS) X-ray free-electron laser will be able to accelerate electrons close to the speed of light.

The inflationary epoch that caused our universe to rapidly expand in its earliest moments may be connected to the modern era of dark energy.

Scientists are investigating the elusive neutrino with a new experiment at the Large Hadron Collider (LHC).

The universe may stop expanding in just 100 million years if dark energy decays over time, a new study suggests.

The newly-upgraded Large Hadron Collider just broke a world record with its proton beams.

Scientists restarted the Large Hadron Collider on April 22 to hunt for dark matter and fringe physics.

As the early universe cooled shortly after the Big Bang, bubbles formed in its hot plasma, triggering gravitational waves that could be detectable even today, a new study suggests.
