This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the Planck length ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

But Luis Jauregui’s work, which might power quantum computers needed for long-range space exploration, also shows how basic research is a smart investment.

While William Rowan Hamilton isn’t a household name like, say, Einstein or Hawking, he might have been. It turns out the Irish mathematician almost stumbled on quantum theory in the or ...

Astrophysicist Paul Sutter explains Quantum Mechanics - the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe.

The world of quantum physics has once again astounded us with a groundbreaking discovery: a new state of quantum matter that can exist in multiple states simultaneously. This revelation not only ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a particle's position and momentum cannot be known at the same time with absolute ...

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A ...
