The Universe didn't begin with a bang, but with an inflationary "whoosh" that came before. Here are the biggest questions that still remain.

All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
With the right material at the right temperature and a magnetic track, physics really does allow perpetual motion without energy loss.
Life became a possibility in the Universe as soon as the raw ingredients were present. But living, inhabited worlds required a bit more.
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.
Decades of Alzheimer's research might have missed a cellular culprit hiding in plain sight.
Atomic nuclei form in minutes. Atoms form in hundreds of thousands of years. But the "dark ages" rule thereafter, until stars finally form.
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 community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.
A non-invasive method for looking inside structures is solving mysteries about the ancient pyramid.
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.
The familiar terrain of solids, liquids, and gases gives way to the exotic realms of plasmas and degenerate matter.
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn't) bound together.
Some constants, like the speed of light, exist with no underlying explanation. How many "fundamental constants" does our Universe require?
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
"Imagination is more important than knowledge" is often taken to mean that your conceptions outweigh what's real. That's not what he said.
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it's magical.
Sam Smith — founder and former CEO of finnCap Group — argues that a culture of empathy will help superscale any business.
Like Dua Lipa, he had to create new rules.
Now they're pointing the way to future battery technologies.
Dark matter hasn't been directly detected, but some form of invisible matter is clearly gravitating. Could the graviton hold the answer?
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
Short-hop regional flights could be running on batteries in a few years.
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.
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we finally found them.
The site will be the first working example of a geological disposal facility.
