World’s Highest Jumping Robot

August 31st, 2022

This tiny robot can jump higher than anything else in the world. This video is sponsored by Brilliant. The first 200 people to sign up via https://brilliant.org/veritasium get 20% off a yearly subscription.

Huge thanks to Dr. Elliot Hawkes and the rest of the group – Charles Xiao, Chris Keeley, Dr. Morgan Pope, and Dr. Günter Niemeyer – for having us at UCSB and showing us their high-flying jumper. This work was partially supported by an Early Career Faculty Grant from NASA’s Space Technology Research Grants Program.

What Makes The Strong Force Strong?

Quantum mechanics gets weirder as you go to smaller sizes and higher energies. It’s strange enough for atoms, but positively bizarre when we get to the atomic nucleus. And today we’re going nuclear, as we dive into the weird world of quantum chromodynamics and the strong force.

What If Dark Energy is a New Quantum Field?

August 17th, 2022

PBS Member Stations rely on viewers like you. To support your local station, go to:http://to.pbs.org/DonateSPACE

What is Quintessence? Well we know that something is up with the way the universe is expanding – there’s some kind of anti-gravitational effect that’s causing the expansion to accelerate. We don’t know what it is – just that it competes against the inward-pulling effect of gravity. And it’s winning – it looks like the universe will expand forever, at an ever-increasing rate. We call this mysterious influence dark energy, but while we’ve talked a lot about how it behaves, we’ve never really explored what it is. So, what is dark energy, really?

One strong possibility is quintessence. Quintessence is a hypothetical form of dark energy, more precisely a scalar field. Watch the episode to learn more.

A Cover up at Hueyatlaco – Have Humans ALWAYS been in the Americas?

August 8th, 2022

If you would like to support my work, please consider purchasing a copy of my book, Enigmatic North America: Legends, Oddities, and Controversial History. There are over 200 high quality photos in this book and it is full of mind-blowing information. Available in paperback on Amazon or the Ebook/PDF on my website. I would greatly appreciate your review on Amazon! Thanks for the support!
Link to my book -https://www.amazon.com/dp/B0CLK35R13

This is an overview of the cover up at Hueyatlaco, near Puebla, Mexico. Arguably the biggest cover up in the History of Archeology, the findings at Hueyatlaco point to a possible new paradigm of understanding. The artifacts found at the Valladolid Reservoir were so old that it shocked everyone involved.

To learn more, check out this book and documentary on the Subject.
Book – The first Americans by Chris Hardaker – https://www.amazon.com/First-American-Suppressed-People-Discovered/dp/1564149420/ref=sr_1_1?crid=2FPCH5CRSQSDI&keywords=the+first+Americans+Christopher+hardaker&qid=1659922493&sprefix=the+first+americans+christopher+hardakaps562&sr=8-1

What Happens Inside a Proton?

If we ever want to simulate a universe, we should probably learn to simulate even a single atomic nucleus. But it’s taken some of the most incredible ingenuity of the past half-century to figure out how that out. All so that today I can teach you how to simulate a very very small universe.

How Many States Of Matter Are There?

Enjoy Far Out (https://youtu.be/jpUjze3v_6c) and Why Am I Like This (https://youtu.be/eWzBNfBnFys) on PBS Terra ( https://youtube.com/pbsterra)

PBS Member Stations rely on viewers like you. To support your local station, go to:http://to.pbs.org/DonateSPACE

Let’s talk about states of matter. You know your states of matter don’t you? We have solids, liquids and gasses, and plasmas, quark-gluon plasmas, nuclear matter, bose-einstein condensates, neutronium, time crystals, and sand. Come to think of it, maybe I don’t know my states of matter. Or what a state of matter even is. Let’s see if we can figure it out.

A Dangerous hike to Cliff Dwellings in Arizona

July 20th, 2022

These cliff dwellings were created by the Salado people. We hiked 9.6 miles round trip in very tough terrain to see the ruins for ourself. This hike is very dangerous. There are rattlesnakes and heat stroke can take place quickly. It is steep. It is extremely remote and evacuation very difficult.

The rules and consequences for breaking those rules are clearly marked on the trail. Do not harm any of the ruins or take any artifacts found.

Today we’re going to try to save reality – or at least realism. However this rescue effort has a price; one that you may not be willing to pay. Your very soul, or at least your free will, is on the line.
