There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.

Your life’s memories could, in principle, be stored in the universe’s structure.
No matter how beautiful, elegant, or compelling your idea is, if it disagrees with observation and experiment, it’s wrong.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
Dark matter has never been directly detected, but the astronomical evidence for its existence is overwhelming. Here’s what to know.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
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.
Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
Contrary to conventional wisdom, matter can escape the center of the Earth.
The authors call it “wildly theoretical” — but let’s take a look, anyway.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
A new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
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.
In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.
The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe’s biggest mysteries.
Chemists could replace bubbling flasks with tumbling ball mills.
Quantum entanglement may remain spooky, but it has a very practical side.
“It is more human to laugh at life than to lament it.”
We cannot afford to dream about living on other worlds while we continue to destroy ours.
NASA’s minivan-sized drone is scheduled to search for signs of life on Titan in 2034.
