What if the universe isn’t a cold, indifferent void, but something more like a vast, slowly breathing creature? It sounds like science fiction, yet a growing number of physicists, cosmologists, and philosophers are taking versions of this idea seriously enough to write papers, build models, and argue at conferences about it. For them, the ...
For more than a century, astronomers have been measuring how quickly the universe is flying apart, quietly assuming that with better telescopes and cleaner data, all the numbers would eventually agree. Instead, the opposite is happening. New observations, from ultra-precise space telescopes to clever uses of exploding stars and gravitational waves, are sharpening a ...
Somewhere beyond the edge of what our telescopes can see, there may be another universe that looks eerily like our own – same laws of physics, same cosmic ingredients, but running on a kind of mirror-time. In the last few years, a series of bold ideas in cosmology has revived an astonishing possibility: that ...
The idea that everything you see, feel, and remember might be running on someone else’s server sounds like it belongs in late-night dorm-room debates, not serious science. Yet over the last two decades, researchers from physics, computer science, and philosophy have started taking the simulation hypothesis seriously enough to model, test, and argue about ...
On the grandest scales, the universe looks less like a random scatter of galaxies and more like a ghostly spiderweb stretching across unimaginable distances. For decades, astronomers suspected there was an underlying pattern, but only in recent years have powerful telescopes and supercomputers begun to reveal its full, intricate geometry. This so‑called cosmic web ...
Somewhere between the galaxies we can see and the void we can’t quite grasp lies a missing ingredient that refuses to reveal itself. Astronomers call it dark matter, and without it, the universe as we know it simply does not add up. Galaxies spin too fast, clusters of galaxies cling together too tightly, and ...
For more than a century, physics has told us a strangely incomplete story: equations that work beautifully on paper but leave us wondering why time flows one way, why matter won over antimatter, and why the universe looks so finely balanced. Now, a handful of recent studies are quietly proposing a radical possibility hiding ...
On the largest scales we can see, the universe is doing something deeply counterintuitive: instead of slowing down under the pull of gravity, galaxies are racing away from each other faster and faster. For more than two decades, this runaway expansion has been blamed on a vague, unsettling concept called dark energy, a kind ...
Not long ago, many astronomers quietly assumed the universe’s expansion was slowing down, like shrapnel from a blast gradually tugged back by gravity. Then, in the late nineteen‑nineties, two teams studying dying stars stumbled on a result so unsettling that some thought they had made a mistake: distant galaxies were not just receding, they ...
For decades, astronomers imagined the universe’s first stars as lonely giants, but still within a vaguely familiar range. Now, emerging evidence suggests those primordial suns were not just big – they were extreme, dwarfing almost anything we see today and rewriting the rules of how matter first lit up the cosmos. Instead of modest ...
