When supermassive black holes merge, they emit more energy than anything else to occur in our Universe except the Big Bang.

From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
Today, the Large Hadron Collider is the most powerful particle physics experiment in history. What would a new, successor collider teach us?
Researchers at the Brookhaven National Laboratory recently created the heaviest exotic antimatter hypernucleus ever observed.
As we pursue the leadership difference we seek, we attract fuel and generate heat. The trick is to avoid burnout.
The Universe isn’t just expanding, the expansion is also accelerating. If that’s true, how will the Milky Way and Andromeda eventually merge?
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so… solid?
The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli’s rule, our Universe wouldn’t exist.
To know how to protect its astronauts, NASA needs to first understand the threat.
The Big Bang’s hot glow faded away after only a few million years, leaving the Universe dark until the first stars formed. Oh, the changes!
You can only create or destroy matter by creating or destroying equal amounts of antimatter. So how did we become a matter-rich Universe?
Wind farms seem less productive when scientists incorporate more realistic atmospheric models into their output predictions.
A great many cosmic puzzles still remain unsolved. By embracing a broad and varied approach, particle physics heads toward a bright future.
Earth, the only rocky planet with a large, massive satellite, is greatly affected by the Moon. Destroying it would cause 7 major changes.
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
The properties of a ghostly particle called a neutrino are coming into focus.
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
Cosmologists are largely still in the dark about the forces that drive the Universe.
Is the Universe finite or infinite? Does it go on forever or loop back on itself? Here’s what would happen if you traveled forever.
Symmetries aren’t just about folding or rotating a piece of paper, but have a profound array of applications when it comes to physics.
The laws of physics don’t prefer matter over antimatter. So how can we be certain that distant stars & galaxies aren’t made of antimatter?
If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.
The hot Big Bang was an energetic, brilliantly luminous event. Today’s Universe is alight with stars. But in between, the dark ages ruled.
When you combine the Uncertainty Principle with Einstein’s famous equation, you get a mind-blowing result: Particles can come from nothing.
While humanity has been skywatching since ancient times, much of our cosmic understanding has come about only recently. Very recently.
The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?
For decades, theorists have been cooking up “theories of everything” to explain our Universe. Are all of them completely off-track?
In the early stages of the hot Big Bang, there were only free protons and neutrons: no atomic nuclei. How did the first elements form from them?
We can reasonably say that we understand the history of the Universe within one-trillionth of a second after the Big Bang. That’s not good enough.
