The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

Between the end of cosmic inflation and the formation of the first atoms, the universe experienced a fleeting but pivotal era ...

In the blink of an eye after the Big Bang, the universe could have birthed strange new stars and black holes.

Nobel laureate who mapped temperature variations in the cosmic microwave background.

If this new model of the universe is right, there were boson stars and cannibal stars hundreds of millions of years before ...

Did the universe really begin with a Big Bang? And if so, is there evidence? Are there planets around other stars? Can they support life? The 2019 Nobel Prize in Physics goes to three scientists who ...

The Big Bang theory is supported by the discovery of the cosmic microwave background radiation. The universe rapidly expanded and cooled after the Big Bang. Light elements like helium and lithium ...

The expanding Universe, full of galaxies and the complex structure we observe today, arose from a smaller, hotter, denser, more uniform state. But even that initial state had its origins, with cosmic ...

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been ...
