What Happens During a Quantum Jump?
Erratum: Figures in the episode should be Minev et al. (2019), not Minney et al. (2009). Our apologies to the authors! This is the experiment we talk about: To Catch and Reverse a Quantum Jump Mid-Flight Minev, Mundhada, Shankar, Reinhold, Gutiérrez-Jáuregui, Schoelkopf, Mirrahimi, Carmichael & Devoret (2019), Nature, v.570, p.200 https://doi.org/10.1038/s41586-019-12… Sign Up on Patreon to get access to the Space-Time Discord! https://www.patreon.com/pbsspacetime Since the very beginning of quantum mechanics, a debate has raged about how to interpret its bizarre predictions. And at the heart and origin of that debate is the quantum jump or quantum leap – the seemingly miraculous and instantaneous transitions of quantum systems that have always…

Navigating With Quantum Entanglement
We often think of quantum mechanics as only affecting only the smallest scales of reality, with classical reality taking over at some intermediate level. But in his 1944 book, What is Life?, the quantum physicist Erwin Schrödinger suggested that “incredibly small groups of atoms, much too small to display exact statistical laws, do play a dominating role in the very orderly and lawful events within a living organism.” Schrodinger was a visionary – and perhaps very specifically in this case. Because it turns out we might need all the weirdness of quantum mechanics to explain birds. Check out the Space-Time Merch Store https://pbsspacetime.com/ Sign up for the mailing list to…

The Formula That Will Determine Our Energy Future
We all want a cleaner, more renewable energy. But when it comes down to it, the energy of the future is going to be the cheapest energy. So in this video, we compare energy production by the Levelized Cost of Energy, or LCOE – the formula that will determine our energy future.

Could Humans Actually Build A Dyson Sphere?
Dyson spheres come up a lot in science fiction, as well as in discussions around alien civilizations. But what are they? Do they exist and the even bigger question… Could humans ever make one?

Why The Bubonic Plague Still Exists Today
When you think of the Plague, the Black Death of the 14th century, with its medieval cities overrun with rats and creepy plague masks, probably comes to mind. But the Plague isn’t a disease of the past; it’s still very much around. There are actually three major types of plague depending on what part of the body is affected. Septicemic, pneumonic, and bubonic, which is what we think of when we hear “the plague” since it’s the most common type. Symptoms may include fever, chills, body aches, nausea, and vomiting, all of which can usually take anywhere between one to seven days to pop up. But probably the most important…

Why Isn’t There a Cure For the Common Cold?
The common cold is the most common human disease in the world. So, why haven’t we found a cure yet?! Called human rhinoviruses, these respiratory viruses measure between 15 to 30 nanometers in diameter, making them some of the smallest types of viruses out there. And it’s partly thanks to the viruses’ genetic makeup that they’re so good at replicating. Human rhinoviruses travel like most other respiratory viruses via nasal secretions, which can be released through sneezing, or through contact with fomites, which are surfaces like a keyboard or a doorknob that can help spread the virus from one person to another. From there, all it takes is for a…

Superconducting X-ray Laser Engineered To Image The Atomic World
The LCLS-II will be the world’s brightest x-ray laser when it delivers “first light” in the early 2020s. With this superconducting accelerator online, scientists will be able to see the hidden world of atoms and molecules like never before. The LCLS is short for the Linac Coherent Light Source. It’s the world’s first hard x-ray free-electron laser. The LCLS uses a particle accelerator to fire extremely bright electrons to create fast pulses of hard x-rays, which is why the machine is called an x-ray laser. At the time of its first light in 2009, the Linac Coherent Light Source generated x-ray pulses a billion times brighter than anything around. The…

NASA’s Mega Hubble – The Roman Space Telescope
What do you do when the NRO (National Reconnaissance Office) makes you an offer you can’t refuse?. Well in the case of NASA you update an existing design to create a Hubble on steroids that can cover the same amount of sky as one hundred Hubble’s, drastically cutting down the time survey the sky and also more accurately look for Neptune sized planets around nearby stars and gather evidence to hopefully find out what dark energy really is, this is NASA upcoming Roman space telescope.

The Supernovae At The End of The Universe
Good news everyone: it looks like the universe is going to end with a series of catastrophic explosions. The very, very long story short is that the universe ends in heat death, as it approaches maximum entropy, and its eternal exponential expansion drives it to effective utter emptiness and absolute cold. But new calculations have revealed we may be able to look forward to one last source of astrophysical cataclysms – a new type of supernova that can only happen at the end of the universe.

Can Free Will be Saved in a Deterministic Universe?
Physicists have a long history of sticking our noses where they don’t belong – and one of our favorite places to step beyond our expertise is the question of consciousness and free will. Sometimes our musings are insightful, sometimes incoherent, and usually at least somewhat naive. Which a fair description of this show, so of course Space-Time needs to weigh in physics and free will..
