The science of making fruits and veggies last longer | Jenny Du
New ReviewIt's a hard nut to crack: in order to prevent food waste, we rely on plastic packaging and refrigeration, which harm the environment. What if we could turn to nature to address these challenges? Engineer and chemist Jenny Du shares how a...

How AI could generate new life-forms | Eric Nguyen
New ReviewIf DNA is just a string of letters, could AI learn to read it … or even write it? Bioengineering researcher Eric Nguyen reveals how AI has upended the rules of biology, potentially creating a future where disease is cured with...

Is It Impossible To Cross The Event Horizon? (Black Hole Firewall Paradox)
So you’ve decided to jump into a black hole. Good news: as long as the black hole is big enough you can sail through the event horizon without harm and get to experience the interior of the black hole before you’re annihilated by the...

What Happens If You Jump Into A Black Hole?
Meet Alice and Bob, famous explorers of the abstract landscape of theoretical physics. Heroes of the gerdankenexperiment—the thought experiment—whose life mission is to find contradictions in the deepest layers of our theories. Today our...

Do Black Holes Have to Be Black?
The primary characteristic that defines black holes is in the name. Black holes are black. The gravitational pull at the event horizon is so powerful that not even light can escape. In this case, black means absence of light. We also...

Can We Create New Elements Beyond the Periodic Table
Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

What If The Universe Did Not Start With The Big Bang?
Here’s the story we like to tell about the beginning of the universe. Space is expanding evenly everywhere, but if you rewind that expansion you find that all of space was once compacted in an infinitesimal point of infinite density—the...

Do Neutron Stars Shine In Dark Matter?
Neutron stars aren't dark matter--we figured that out a while ago. But new research is telling us that they may be dark matter factories. They may produce the exotic axion, one of the most popular dark matter candidates.

Does the Planck Length Break E=MC^2?
Every good nerd knows that E=mc^2. Every great nerd knows that, really, E^2=m^2c^4+p^2c^2 Want to know what that even means? Sure, I’ll tell you, but today I’d like to invite you to an even higher level of nerdom with extra bits to...

What Does An Electron Actually Look Like?
What does an electron really look like? I mean, if we zoom in all the way. Is it a sizeless speck of charge? Is it a multidimensional vortex of quantum strangeness? Is it the boundary of a tiny universe with universe-electrons of its...

Does Infinity - Infinity = an Electron
What do you get if you take something that’s infinitely massive and combining with something else that’s negative infinitely massive? You get a single electron, at least that’s what it looks like in our most precise way of describing the...

Does Timescapes Disprove Dark Energy?
The universe is expanding and that expansion is accelerating under the power of dark energy and eventually all matter and energy will be dispersed over such unthinkable distances that nothing can stop space from blowing up infinitely....

Is There A Simple Solution To The Fermi Paradox?
Around 2 billion years ago, life had plateaued in complexity, ruined the atmosphere, and was on the verge of self-annihilation. But then something strange and potentially extremely lucky happened that enabled endless new evolutionary...

Will The Big Bang Happen Again (and Again)?
How did the universe begin? How can something come from nothing? One way to “solve” this most difficult of philosophical conundrums is to avoid it altogether. Maybe the universe didn’t begin. Maybe the Big Bang was just one in an endless...

How Astrophysics Can Literally Save the World
Giant space rocks are definitely going to hit the Earth again. We actually do know how to deflect them, but only if we find them and correctly assess their risk. But the solar system is a chaotic place. How is it even possible to tell if...

The Crisis In Physics: Are We Missing 17 Layers of Reality?
Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in a nutshell, and digging our way to the smallest layer has been one of the primary goals of physics for ever. But...

Can a Particle Be Neither Matter Nor Force?
All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and gluons transmit the fundamental forces. And that about covers the universe: matter moving...
