New research highlights a troubling problem with the concept of a cyclical universe that experiences infinite expansion and contraction, known as 'bouncing universe' models.
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 "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.
Reference Chaos theory explains the behavior of dynamic systems like weather, which are extremely sensitive to initial conditions. They cannot be truly predicted.

Infographic Most astronomers believe the universe began 13.8 billion years ago in a sudden explosion called the Big Bang. Other theorists have invented alternatives and extensions to this idea.
A new museum exhibit hopes to uncover the secrets behind the doodles, in-jokes and coded messages on a blackboard that Stephen Hawking kept for more than 35 years.
Our universe was born 13.7 billion years ago in a massive expansion that blew space up like a giant balloon.
