Extras
The universe expands faster. “Dark energy” may not be constant after all.
There’s a new generation of experiments that may unlock the gravity particle.
The universe thrums with quantum fields, except something may be missing: the sterile neutrino.
Gravitons, the particle of quantum gravity, may be impossible to detect.
We go in depth on black holes: the strangest objects in the universe!
2025 was the international year of quantum science, but today we examine its origins.
We’ve found lots of “habitable” worlds but we don’t know what factors are needed for life.
What is the graviton, and does it even exist?
Does quantum mechanics allow the future to retroactively influence the past or not?
Antimatter drives sound like science fiction, but they may not be as far as you think.
