Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

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 ...

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 ...

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 ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

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 ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Decadal surveys of the National Academies of Sciences, Engineering, and Medicine bring together leading experts to identify a field’s most compelling science challenges and frontiers for the next ...

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 ...
