As we gain new knowledge, our scientific picture of how the Universe works must evolve. This is a feature of the Big Bang, not a bug.
The James Webb Space Telescope has chosen 5 targets for its first science release. Here’s what we know on the eve of JWST’s big reveal!
Or are cults the religions we find distasteful?
NASA will use energy from Earth’s gravity to launch the Lucy spacecraft in October of this year.
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
Despite all that we’ve learned about the Universe, there remain unanswered, and possibly unanswerable, questions. Could “God” be the answer?
Dark matter’s hallmark is that it gravitates, but shows no sign of interacting under any other force. Does that mean we’ll never detect it?
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
Observations of an enormous cosmic structure, dubbed the “Big Ring,” seem to violate the Copernican principle.
The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
In many ways, we are still novices playing with toy models seeking to understand the stars.
Architecture in the age of AI — argues professor Nayef Al-Rodhan — should embed philosophical inquiry in its transdisciplinary toolkit.
Experiments on suborbital rockets are revealing how to make a better iron furnace.
At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?
New technology is helping physicists move forward in the search for the Theory of Everything.
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
An army of replicators belonging to national laboratories, research universities, and amateur garages is rushing to replicate ambient superconductivity in LK-99.
Extremely precise atomic clocks are not just of theoretical interest; they could help detect impending volcanic eruptions or melting glaciers.
Nothing lives forever, at least, not in the physical Universe. But relativity allows us to get closer than ever, from one perspective.
The hunt for the elusive particles continues.
Human civilization has always survived periods of change. Will our rapidly evolving technological era be an exception to the rule?
Within our observable Universe, there’s only one Earth and one “you.” But in a vast multiverse, so much more becomes possible.
Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.
Recent measurements of subatomic particles don’t match predictions stemming from the Standard Model.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
A reader asks whether we have an ethical responsibility to always debate bad beliefs, especially those that come from our elders.
Besides offering an incredibly cool way to get stuff into space, SpinLaunch promises to reduce the cost of a launch by 20-fold.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
