Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Looking up at the night sky, it may seem our cosmic neighborhood is packed full of planets, stars and galaxies. But scientists have long suggested there may be far fewer galaxies in our cosmic ...

To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships between different events or fields in spacetime, broadly referred to as ...

Primordial black holes are the earliest black holes thought to exist, and they vanished almost as fast as they came into being. As Stephen Hawking predicted, black holes don’t only draw particles in, ...

Our latest and best ever map of the early universe is five times more detailed than anything we have had before, but while it precisely backs up the leading model of the universe, it is also a ...

“You build these machines not to confirm the paradigm but to break it,” European Space Agency senior science and exploration adviser Mark McCaughrean said. This logic underlies the iconoclastic ...

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted. Reading time 5 minutes Following the Big Bang, ...

Cosmic inflation posits a transient epoch of accelerated expansion in the first fractions of a second after the Big Bang, driven by the dynamics of one or more scalar fields collectively known as ...

Dr. Niayesh Afshordi, professor at the University of Waterloo and Perimeter Institute, draws the renormalization group flow for quadratic quantum gravity (University of Waterloo). Waterloo scientists ...
