Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?
To Fred Hoyle, the Big Bang was nothing more than a creationist myth. 75 years later, it’s cemented as the beginning of our Universe.
The authors call it “wildly theoretical” — but let’s take a look, anyway.
From physics and alchemy to theology and eschatology, Isaac Newton’s research was rooted in a personal pursuit of the Divine.
The record-breaking transmission could revolutionize deep space communication.
Your life’s memories could, in principle, be stored in the universe’s structure.
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.
Quantum entanglement may remain spooky, but it has a very practical side.
In all of science, no figures have changed the world more than Einstein and Newton. Will anyone ever be as revolutionary again?
“The surface is no longer a record of every impact the moon has ever had, because at some point, impacts were erasing previous impacts.”
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
We cannot afford to dream about living on other worlds while we continue to destroy ours.
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
Even the dictionary doesn’t get the definition right.
“It is more human to laugh at life than to lament it.”
Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.
We knew we’d find galaxies unlike any seen before in its first deep-field image. But the other images hold secrets even more profound.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
Contrary to conventional wisdom, matter can escape the center of the Earth.
When stars form, they emit energetic radiation that boils gas away. But it can’t stop gravitational collapse from making even newer stars.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.
Light can be turned into heat, which can then be turned into motion, and the effect of that motion can be turned into a big squeeze.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
