"There are different parallel universes where things are roughly the same, and each one is mathematically on a separate space-time manifold."

Paradox-free time travel possible with many parallel universes

Alternate Timelines

A pair of physicists have come up with a solution to the time travel paradox that requires a very large — but not infinite — number of parallel histories.

Paradox-Free Time Travel Possible With Many Parallel Universes

Would you step through a wormhole to a different timeline to kill Hitler?

"I really think that it shows that if you love what you do it’ll radiate to other people."

Adorable physics prof finally gets his viral moment of fame

Wholesome Physics

A viral video uploaded on Wednesday by college student Erica Church shows her physics professor David Wright jovially pull off some amazing tricks in class.

Adorable Physics Prof Finally Gets His Viral Moment of Fame

Oh, and he's 69 years old.

"This discovery of a possible fifth force [of nature] would completely change our understanding of the universe."

Physicists discover evidence of a new force of nature

Force Finding

Researchers have discovered new evidence of a fifth force of nature, and if confirmed, the work could help us understand dark matter.

Physicists Discover Evidence of a New Force of Nature

This could be the key to understanding dark matter.

Do you prefer your spacetime chunky or smooth?

Satellite mission will investigate whether reality is pixelated

Smooth Spreading

A new mission plans to determine once and for all whether spacetime is a smooth fabric or a chunky mess of discrete units.

Satellite Mission Will Investigate Whether Reality Is Pixelated

They want to probe the fabric of our universe.

Scientists are challenging long-held assumptions about the universe to hunt down dark matter.

New research: antimatter could be portal to "dark universe"

Exhausting Options

A team of physicists attempted a bizarre new way to spot dark matter: using antimatter probes. It hasn't worked yet, but the scientists have some ideas.

New Research: Antimatter Could Be Portal to “Dark Universe”

Scientists have a new plan to spot dark matter.

Unsurprisingly, the research is pretty flawed.

Paper in peer-reviewed journal claims women are bad at physics

That Ain't It

A peer-reviewed academic journal has made the bizarre choice to publish a paper that says women are inherently worse at physics despite knowing it's flawed.

Paper in Peer-Reviewed Journal Claims Women Are Bad at Physics

The journal is taking a "both sides" approach to publishing controversial papers.

Will we have to throw out all of astrophysics?

Scientists: Something about the universe doesn’t look right

Bro.

Yet another study has calculated the Hubble Constant and come to a different conclusion, raising more questions about the nature of our universe.

Scientists: Something About the Universe Doesn’t Look Right

The numbers just don't add up. 

If the calculations are correct, the discovery could force us to rethink how we understand the way stars are born and die.

Astronomers spot black hole the size of Manhattan

NYC Black Hole

Astronomers claim to have spotted a tiny black hole that's only 20 kilometers across. That's tiny.

Astronomers Spot Black Hole the Size of Manhattan

The diameter of this cosmic monster is about 12 miles.

It could mean better medical equipment or stealth planes.

Scientists built a working "quantum radar" device

Quantum Peekaboo

A working quantum radar device uses low-energy microwaves to spot objects that remain invisible to conventional radar technology.

Scientists Built a Working “Quantum Radar” Device

The device uses entangled microwaves.

"...this work can enable a large number of science projects throughout the research community."

Scientists will use a supercomputer to simulate the universe

Cosmological Cheat Sheet

Physicists at the Argonne National Lab are about to use the Mira supercomputer to simulate the universe, perhaps helping them find dark energy and matter.
