Researchers confirmed that the distant galaxies discovered by the James Webb Space Telescope are, indeed, perfectly compatible with our modern understanding of cosmology.
Big Bang theory is the leading explanation for how our universe began. According to the theory, the entire universe began as a tiny singularity that went through an explosive expansion 13.8 billion years ago, gradually expanding into the cosmos we see today. Today, astronomers can detect an "echo" from the Big Bang in the cosmic microwave background, a phenomenon that can be detected with radio telescopes. Big Bang Theory is also the name of a popular CBS sitcom about scientists, where several real-life scientists and astronauts have appeared.
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.
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.
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).
What mysteries of the universe could the world's largest and most powerful particle accelerator unlock?
The universe may stop expanding in just 100 million years if dark energy decays over time, a new study suggests.
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.
