Everything everywhere all at once.
The hot Big Bang is often touted as the beginning of the Universe. But there’s one piece of evidence we can’t ignore that shows otherwise.
How scientists found out that we live in a cosmic aquarium.
When supermassive black holes merge, they emit more energy than anything else to occur in our Universe except the Big Bang.
We can’t go back to the Big Bang, nor ahead to the heat death of the Universe. Nevertheless, here are today’s natural temperature extremes.
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where’s the line between them?
Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?
Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.
Not even Einstein immediately knew the power of the equations he gave us.
The zero-point energy of empty space is not zero. Even with all the physics we know, we have no idea how to calculate what it ought to be.
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
If stars don’t go supernova at first, they can get a second chance after becoming a white dwarf. But can their companions survive?
The road to intelligent life is a series of hard steps.
In our Solar System, even the two brightest planets frequently align in our skies. But only rarely is it spectacularly visible from Earth.
All human development, from large cities to small towns, shines light into the night sky.
Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.
JWST’s revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA’s Spitzer first, it wouldn’t have been possible.
The Fermi paradox (along with the subsequent Drake equation) is so difficult that even brilliant thinkers can make little dent in it.
Dark energy is one of the biggest mysteries in all the Universe. Is there some way to avoid “having to live with it?”
Some of them have survived the wilds of space for billions of years.
Nobel Laureate Roger Penrose, famed for his work on black holes, claims we’ve seen evidence from a prior Universe. Only, we haven’t.
ChatGPT doesn’t understand physics, but it memorizes very well and puts in extra effort.
An incredible composite image of Pandora’s Cluster, Abell 2744, simultaneously showcases both our impressive knowledge and vast ignorance.
We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.
The glorious sights that JWST keeps revealing are less than a millionth of the whole Universe. Just imagine what else is out there.
You can’t throw a DART at everything in space.
Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
