The idea that reality is comprised of atoms and space goes way, way back.

You might think that it should be all black, but then how would we see it? “It is conceptually interesting, if not astrophysically very important, to calculate the precise apparent shape […]

Looking at how our technology and culture compare to Star Trek’s vision of the future.

Bill Nye is always dressed for a party, but this time his celestial bow-tie pays respect to one of our era’s greatest discoveries: gravitational waves.

There’s really something new there, even if physicists forget. “Losing an illusion makes you wiser than finding a truth.” –Ludwig Borne In 1998, two teams of scientists announced a shocking […]

Could the secret to understanding gravity be held in reducing, not increasing, the number of dimensions? This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]

And can we even agree on the definition of ‘nothingness’? “Alone, I often fall down into nothingness. I must push my foot stealthily lest I should fall off the edge […]

You lose whether you use protons or electrons in your collider, for different reasons. Could the unstable muon solve both problems? “It does not matter how slowly you go as […]

Sometimes, designing a careful experiment and measuring absolutely no effect can be the most important result of all. “It appears, from all that precedes, reasonably certain that if there be any […]

With gift ideas from as little as $11, there might be something to tickle anyone’s fancy. “It is worthy of notice that in Table VI the brighter variables have the longer […]

Researchers create a new theory of time that goes against established physics.

What’s the difference between “point-like” and what we can actually state? “When we think about the present, we veer wildly between the belief in chance and the evidence in favour of […]

If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]

Yale researchers create a groundbreaking device that utilizes two key concepts in quantum physics.

Physicists may be close to creating the theoretical “time crystals”.

And it doesn’t mean we should give up, but it does mean we’ve got a lot of work to do! “‘Star Trek’ says that it has not all happened, it has […]

If black holes lose information in an event horizon, then do we have a paradox with our cosmic horizon? “The history of astronomy is a history of receding horizons.” –Edwin Hubble […]

In Netflix’s “Stranger Things” characters enter a parallel dimension. Could this actually happen?   

A theoretical physicist proposes a new way to think about gravity and dark matter.

How humanity discovered where our elements come from. This article was written by physicist Paul Halpern of the University of the Sciences in Pennsylvania. Paul is author of the new book […]

The force of empty space isn’t always zero. Here’s how an electromagnetic experiment might be the key to dark energy. “Another very good test some readers may want to look up… […]

LIGO’s world-changing announcement was the beginning. The best is what comes next. “It’s the first time the universe has spoken to us through gravitational waves, up to now we’ve been deaf […]

Could life on Earth have spawned more than once?   

Physicists discover strikingly similar structures in human cells and neutron stars.

A researcher is experimenting with an artificial hippocampus to learn how to strengthen and store memories.l 

George Musser explains the central role of weirdness in physics, and shatters the dreams of those who hope humans can one day tap into psychic powers.

Without the inherent quantum uncertainty to nature, the source of all our light and heat would never shine. “The bedrock nature of space and time and the unification of cosmos and […]

Before the Big Bang… after the Big Freeze… will everything look the same? “What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as […]

Perhaps the limits of what we can observe aren’t just artificial; perhaps there are no limits to what’s out there at all. “Two things are infinite, the universe and human stupidity, […]

Each might be as heavy as an asteroid and as tiny as a decimal point.
