Short-hop regional flights could be running on batteries in a few years.
Now they’re pointing the way to future battery technologies.
If you said “with the Big Bang,” congratulations: that was our best answer as of ~1979. Here’s what we’ve learned in all the time since.
We’re separating the facts about EVs from the fiction.
All the things that surround and compose us didn’t always exist. But describing their origin depends on what ‘nothing’ means.
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we finally found them.
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?
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
The answer to this question is key to understanding why anything exists.
The site will be the first working example of a geological disposal facility.
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.
Deliveries of the $250k Lightyear 0 will start in November 2022.
The Universe is 13.8 billion years old, going back to the hot Big Bang. But was that truly the beginning, and is that truly its age?
Could Russia’s plan actually destroy demand for natural gas?
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?
When white dwarfs explode, they create a type Ia supernovae. After decades of following the leading theory, here’s the complete overhaul!
In the spirit of the 1969 moon landing, we now have a golden opportunity to pursue “nondisruptive” creative solutions.
Positron emission tomography (PET) scans use positrons — the antimatter equivalent of an electron — to locate cancer in the body.
For many years, some cosmologists embraced the idea of an eternal, steady state universe. But science triumphed over philosophical prejudice.
The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.
When Einstein gave General Relativity to the world, he included an extraneous cosmological constant. How did his ‘biggest blunder’ occur?
Across the subterranean United States, not all rocks were created equally.

No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Lasers are all around you. This ubiquitous technology came from our understanding of quantum physics.
