Astroparticle physics and particle cosmology represent converging disciplines that strive to understand the universe from its largest structures down to its most fundamental constituents. In this ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant advancements in our understanding of black holes, cosmology and quantum gravity. Plus, ...

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden contraction and then bounced into the expanding universe we know today is not ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

I have been to more scientific conferences than I care to count, but a recent meeting held on the island of Helgoland to celebrate the centenary of quantum mechanics is one of the strangest – in a ...

Students are getting a unique perspective on the quantum field and industry through a program they themselves are helping to shape. Quantum Scholars, which launched in 2023, is providing community and ...

Drexel’s Department of Physics hosted its annual Kaczmarczik Lecture and Science Fair on February 27. This year’s Kaczmarczik Lecture was the 24th installment of this signature College of Arts and ...
