Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Space weather has matured from a niche concern to a central pillar of space exploration, national security, and scientific inquiry. In addition to its natural 11-year cycle of rising and falling ...

Daryl Janzen does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

In this episode of Space Minds, host David Ariosto speaks with Juan Alonso — CTO and Co-founder of Luminary Cloud and professor at Stanford University — about the rapid transformation underway in ...
