A non-invasive method for looking inside structures is solving mysteries about the ancient pyramid.
“Imagination is more important than knowledge” is often taken to mean that your conceptions outweigh what’s real. That’s not what he said.
Most electric car charging is done at night. A grid powered mostly by renewable energy might not be able to meet demand, but there is a solution.
The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?
Everything we observe beyond our Local Group is speeding away from us, omnidirectionally. If the Universe is expanding, where is the center?
In 1974, Stephen Hawking showed that even black holes don’t live forever, but emit radiation and eventually evaporate. Here’s how.
The Parker Solar Probe is about to undergo its seventh encounter with Venus on its journey toward the Sun. Here’s how fast it’ll go.
Although many of Einstein’s papers revolutionized physics, there’s one Einsteinian advance, generally, that towers over all the rest.
When Einstein gave General Relativity to the world, he included an extraneous cosmological constant. How did his ‘biggest blunder’ occur?
Empty space itself, the quantum vacuum, could be in either a true, stable state or a false, unstable state. Our fate depends on the answer.
In the spirit of the 1969 moon landing, we now have a golden opportunity to pursue “nondisruptive” creative solutions.
What do we mean by a black hole’s size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?
Best in class: Denmark and Uruguay. Worst in class: Papua New Guinea, Venezuela, and Russia.
Neuroscientists think a cluster of cells in the brain that stimulate appetite could be a target for eating disorder therapies.
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.
When white dwarfs explode, they create a type Ia supernovae. After decades of following the leading theory, here’s the complete overhaul!
The war in Ukraine is unlikely to trigger a catastrophic nuclear meltdown. Physics and smart engineering are the reasons why.
Mars and Earth were sister planets in many ways, with early similar conditions. Why did Mars die? The leading explanation isn’t universal.
For many years, some cosmologists embraced the idea of an eternal, steady state universe. But science triumphed over philosophical prejudice.
There’s really only one mistake you can make: continue doing the same thing you already know is hurting you and expect a different result.
Economics and religion help to explain the gap.
A team of scientists hopes deep-earth lithium could sustain America’s vast demand for batteries. But extracting it won’t be easy.
Yes, the Universe is expanding, but if you’ve ever wondered, “How fast is it expanding,” the answer isn’t in terms of a speed at all.
The new material may make marine uranium extraction economically feasible.
What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.
Here’s why the answer may forever elude scientists.
“I thought, why not direct these high-power beams, instead of into fusion plasma, down into rock and vaporize the hole?”
