Fighting Carbon With Carbon

12th - Higher Ed
To reduce the amount of carbon dioxide in the atmosphere, some researchers are taking carbon capture technology to the source(s) — for example, slurping up CO2 before it ever leaves the power plant that made it. But that's not all! Some...

The Particle So Extreme Scientists Called it OMG

12th - Higher Ed
In 1991, a subatomic particle smashed into Earth's atmosphere traveling faster than anything humans can replicate. It's the most energetic particle detected to date, and maybe even the fastest (except light itself). Astronomers call it...

How Plankton Created A Bizarre Giant of the Seas

12th - Higher Ed
At more than 2 meters long, Aegirocassis was not only the biggest radiodont ever, but it also may have been the biggest animal in the Early Ordovician. This bizarre marine giant may have only been possible, thanks to a major revolution...

How To Detect a Neutrino

12th - Higher Ed
Why is there something rather than nothing? Well the answer may be found in the weakest particle in the universe: the neutrino. For over half a century Fermilab has been the premier particle accelerator facility of the United States and...

NEW DISCOVERY About Supermassive Black Holes Explained!

12th - Higher Ed
Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky. And has recently swiveled to point its one of these jets directly at us. Is this an...

What If Space And Time Are NOT Real?

12th - Higher Ed
Physics progresses by breaking our intuitions, but we’re now at a point where further progress may require us to do away with the most intuitive and seemingly fundamental concepts of all—space and time.

How Black Holes Spin Space Time

12th - Higher Ed
If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes.

Does Life Need a Multiverse to Exist?

12th - Higher Ed
Life exists in our universe. There we go - one hopefully uncontroversial statement. Therefore our universe is capable of producing and supporting life. How am I going? Two for two? Let’s try for three: therefore there are countless...

Could Life Evolve Inside Stars?

12th - Higher Ed
One of the most bizarre proposals for life not as we know it doesn’t even use atoms. It proposes that fundamental kinks and defects in the fabric of the universe - cosmic strings beaded with magnetic monopoles - may evolve into complex...

The Arrow of Time and How to Reverse It

12th - Higher Ed
Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say traveling backward in time is the same as traveling forwards. So why do we seem to be stuck in this inexorable flow towards...

Will Wormholes Allow Fast Interstellar Travel?

12th - Higher Ed
From Stargate to Interstellar, wormholes are our favorite method for traveling across fictional universes. But they are also a very serious field of study for some of our greatest minds over the last century. So what’s the holdup? When...

What Happens After the Universe Ends?

12th - Higher Ed
Conformal Cyclic Cosmology is a story of the origin and the end of our universe from great mathematical physicist Sir Roger Penrose. It’s goes like this: the infinitely far future, when the universe has expanded exponentially to to an...

Can Future Colliders Break the Standard Model?

12th - Higher Ed

Was the Milky Way a Quasar?

12th - Higher Ed
The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just recently we discovered that its violent past was much more recent than we thought - and...

Building Black Holes in a Lab

12th - Higher Ed
Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

Is Time Travel Impossible?

12th - Higher Ed
Time travel stories are cool because both the past and future are somehow more interesting that the present and because everyone wants a redo. But so far it appears we’re doomed to live consumed by regret in the eternal, boring present....

How Vacuum Decay Would Destroy The Universe

How Many Universes Are There?

Is 'Perpetual Motion' Possible with Superfluids?

What If (Tiny) Black Holes Are Everywhere?

12th - Higher Ed
It’s fair to say that black holes may be the scariest objects in the universe. Happily for us, the nearest is probably many light-years away. Unless of course, Planck relics are a thing - in which case they might be literally everywhere.

Is The Universe Finite?

How An Extreme New Star Could Change All Cosmology
