It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.

Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.
Not even Einstein immediately knew the power of the equations he gave us.
Einstein’s theory of general relativity introduced the concept of space having a shape. So, what is the shape of space?
Adams was infamously scooped when Neptune was discovered in 1846. His failure wasn’t the end, but a prelude to a world-changing discovery.
For nearly 25 years, we thought we knew how the Universe would end. Now, new measurements point to a profoundly different conclusion.
Quantum mechanics has taught us that even empty space contains energy. “Negative energy” is the state of having less energy than empty space.
There are 40 billion billion black holes in the universe. Here’s how our Solar System stacks up against ten of them.
Physicists have yet to pinpoint the hypothetical matter that keeps galaxies from flying apart. Now they have a new focus.
For well over a century, engineers have proposed harnessing the ocean’s tides for energy. But the idea hasn’t seemed to register in many places.
No matter how beautiful, elegant, or compelling your idea is, if it disagrees with observation and experiment, it’s wrong.
Was it the enormous magnitude of the quake, or is the problem with the buildings?
In Einstein’s relativity and the Standard Model, we only have three spatial dimensions. But there could be more, and many think there are.
The most celebrated genius in human history didn’t just revolutionize physics, but taught many valuable lessons about living a better life.
Some of them have survived the wilds of space for billions of years.
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
Dark matter has never been directly detected, but the astronomical evidence for its existence is overwhelming. Here’s what to know.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.
Time gets a little strange as you approach the speed of light.
Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
From before the Big Bang to Voyager 1, particle physicist Harry Cliff takes us on a whiz-bang tour of the Universe’s evolution.
Computer Space lacked a critical ingredient that the other games possessed: gravity.
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it’s coming into focus better than ever before.
The passage of time is something we all experience, as it takes us from one moment to the next. But could it all just be an illusion?
On the largest of cosmic scales, the Universe is expanding. But it isn’t all-or-nothing everywhere, as “collapse” is also part of the story.
The Universe’s history, from cosmic inflation to the Big Bang to the present, is known. But whether it’s infinite or not is still a mystery.
The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.
