Life became a possibility in the Universe as soon as the raw ingredients were present. But living, inhabited worlds required a bit more.

All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
A "bio-battery" made from genetically engineered bacteria could store excess renewable energy and release it as needed.
It has no moving parts and could allow us to tap into renewable energy year round.
With the right material at the right temperature and a magnetic track, physics really does allow perpetual motion without energy loss.
Atomic nuclei form in minutes. Atoms form in hundreds of thousands of years. But the "dark ages" rule thereafter, until stars finally form.
Decades of Alzheimer's research might have missed a cellular culprit hiding in plain sight.
Dr. Tyson explains where we might find aliens, why "dark matter" is a misleading term, and why you can blame physics for your favorite team's loss.
The farther away they get, the smaller distant galaxies look. But only up to a point, and beyond that, they appear larger again. Here’s how.
Should you blast the A/C even when you're not at home?
A non-invasive method for looking inside structures is solving mysteries about the ancient pyramid.
A community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.
The familiar terrain of solids, liquids, and gases gives way to the exotic realms of plasmas and degenerate matter.
EV charging stations are the most widespread alternative to gas and diesel pumps. Each alternative has its own hotspots and "deserts."
IceCube just found an active galaxy in the nearby Universe, 47 million light-years away, through its neutrino emissions: a cosmic first.
Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
Some constants, like the speed of light, exist with no underlying explanation. How many "fundamental constants" does our Universe require?
From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn't) bound together.
Sam Smith — founder and former CEO of finnCap Group — argues that a culture of empathy will help superscale any business.
"Imagination is more important than knowledge" is often taken to mean that your conceptions outweigh what's real. That's not what he said.
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
To Fred Hoyle, the Big Bang was nothing more than a creationist myth. 75 years later, it's cemented as the beginning of our Universe.
Dark matter hasn't been directly detected, but some form of invisible matter is clearly gravitating. Could the graviton hold the answer?
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it's magical.
Like Dua Lipa, he had to create new rules.
Now they're pointing the way to future battery technologies.
Short-hop regional flights could be running on batteries in a few years.
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
