The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
Observations of an enormous cosmic structure, dubbed the “Big Ring,” seem to violate the Copernican principle.
Albert Einstein and his theory of general relativity continue to amaze us to this day.
An army of replicators belonging to national laboratories, research universities, and amateur garages is rushing to replicate ambient superconductivity in LK-99.
Recent measurements of subatomic particles don’t match predictions stemming from the Standard Model.
At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?
Architecture in the age of AI — argues professor Nayef Al-Rodhan — should embed philosophical inquiry in its transdisciplinary toolkit.
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
The hunt for the elusive particles continues.
Nothing lives forever, at least, not in the physical Universe. But relativity allows us to get closer than ever, from one perspective.
In theory, the fabric of space could have been curved in any way imaginable. So why is the Universe flat when we measure it?
A new artificial intelligence method removes the effect of gravity on cosmic images, showing the real shapes of distant galaxies.
Human civilization has always survived periods of change. Will our rapidly evolving technological era be an exception to the rule?
A new paper combines two concepts from the edges of astrophysics: Dyson Spheres and black holes. A Type III civilization could combine them.
Even with only 12.5 hours of exposure time, James Webb’s first deep-field image taught us lessons we’ve never realized before.
Albert Camus was a Franco-Algerian philosopher with some great insights on the meaning of life, why you should look to this life and not the next, and why suicide is a poor choice.
More than any other of Einstein’s equations, E = mc² is the most recognizable to people. But what does it all mean?
Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
Plants at room temperature show properties we had only seen near absolute zero.
If you can model anything in the Universe with an equation, mathematics is how you get the solution(s). Physics must go a step further.
If you want a medication to kick in faster, lean right.
“Superhabitable” planets might be real, but Earth is probably as good as it gets.
A reader asks whether we have an ethical responsibility to always debate bad beliefs, especially those that come from our elders.
The standard model of cosmology has a big new problem: Some galaxies seem to be too old.
“The pulsar sort of consumes the thing that recycled it, just as the spider eats its mate.”
From ancient Greek cosmology to today’s mysteries of dark matter and dark energy, explore the relentless quest to understand the Universe’s invisible forces.
In the early stages of our Solar System, there were three life-friendly planets: Venus, Earth, and Mars. Only Earth thrived. Here’s why.
