Big Picture Science for Aug. 11, 2025: Beyond the Standard Model









Big Picture Science: Beyond the Standard Model

REPEAT
Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics.

Big Picture Science for April 29 2024 - Phreaky Physics







Big Picture Science - Phreaky Physics

REPEAT
It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today.

At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.

Big Picture Science for Monday 15 June 2015 - It's All Relative

Image for Big Picture Science weekly radio show
Big Picture Science - It's All Relative

A century ago, Albert Einstein rewrote our understanding of physics with his Theory of General Relativity. Our intuitive ideas about space, time, mass, and gravity turned out to be wrong.

Find out how this masterwork changed our understanding of how the universe works and why you can thank Einstein whenever you turn on your GPS.

Also, high-profile experiments looking for gravitational waves and for black holes will put the theories of the German genius to the test – will they pass?

And why the story of a box, a Geiger counter, and a zombie cat made Einstein and his friend Erwin Schrödinger uneasy about the quantum physics revolution.

Image for Big Picture Science weekly radio show
Big Picture Science - Mars-Struck

You love to travel. But would you if doing so meant never coming home? The private company Mars One says it will land humans on the Red Planet by 2026, but is only offering passengers one-way tickets. Hundreds of thousands of people volunteered to go.

Meet a young woman who made the short list, and hear why she’s ready to be Mars-bound. Also, why microbes could be hiding in water trapped in the planet’s rocks. And, how a wetter, better Mars lost its atmosphere and became a dry and forbidding place.

Plus, why Kim Stanley Robinson, author of a famous trilogy about colonizing and terraforming Mars, thinks that the current timeline for going to the planet is unrealistic.

Big Picture Science for Monday 19 January 2015 - Big Questions Somewhat Answered

Image for Big Picture Science weekly radio show
Big Picture Science - Big Questions Somewhat Answered

Here are questions that give a cosmologist – and maybe even you – insomnia: What happened after the Big Bang? What is dark matter? Will dark energy tear the universe apart?

Let us help you catch those zzzzs. We’re going to provide answers to the biggest cosmic puzzlers of our time. Somewhat. Each question is the focus of new experiments that are either underway or in the queue.

Hear the latest results in the search for gravitational waves that would be evidence for cosmic inflation, as well as the hunt for dark matter and dark energy. And because these questions are bigger than big, we’ve enlisted cosmologist Sean Carroll as our guide to what these experiments might reveal and what it all means.

Guests:
  • Sean Carroll – Cosmologist, California Institute of Technology
  • Jamie Bock – Experimental cosmologist at the California Institute of Technology and NASA’s Jet Propulsion Laboratory and a member of the BICEP team
  • Brendan Crill – Cosmologist at NASA’s Jet Propulsion Laboratory and member of the Planck collaboration
  • Jeff Filippini – Post-doctoral Fellow, California Institute of Technology, assistant professor of physics at the University of Illinois and member of the Spider team

Big Picture Science for Monday 03 November 2014 - Sounds Abound

Image for Big Picture Science weekly radio show
Big Picture Science - Sounds Abound

ENCORE: The world is a noisy place. But now we have a better idea what the fuss is about. Not only can we record sound, but our computers allow us to analyze it.

Bird sonograms reveal that our feathery friends give each other nicknames and share details about their emotional state. Meanwhile, hydrophones capture the sounds of dying icebergs, and let scientists separate natural sound from man-made in the briny deep.

Plus, native Ohio speakers help decipher what Neil Armstrong really said on that famous day. And, think your collection of 45 rpm records is impressive? Try feasting your ears on sound recorded before the Civil War.

Guests:
  • Bob Dziak – Oceanographer, Hatfield Marine Science Center, Oregon State University, Program Manager, Acoustics Program, NOAA
  • Michael Porter – Senior scientist of H.L.S. Research, La Jolla, California
  • Patrick Feaster – Sound media historian at Indiana University
  • Laura Dilley – Assistant professor in the Department of Communicative Sciences and Disorders, Michigan State University

Big Picture Science for Monday 27 October 2014 - Skeptic Check: Friends Like These

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: Friends Like These

ENCORE: We love our family and friends, but sometimes their ideas about how the world works seem a little wacky. We asked BiPiSci listeners to share examples of what they can’t believe their loved-ones believe, no matter how much they hear rational explanations to the contrary. Then we asked some scientists about those beliefs, to get their take.

Discover whether newspaper ink causes cancer … if King Tut really did add a curse to his sarcophagus … the efficacy of examining your irises – iridology – to diagnose disease … and more!

Oh, and what about string theory? Is it falsifiable?

Big Picture Science for Monday 29 September 2014 - Land on the Run

Image for Big Picture Science weekly radio show
Big Picture Science - Land on the Run

Hang on to your globe. One day it’ll be a collector’s item. The arrangement of continents you see today is not what it once was, nor what it will be tomorrow. Thank plate tectonics.

Now evidence suggests that the crowding together of all major land masses into one supercontinent – Pangaea, as it’s called – is a phenomenon that’s happened over and over during Earth’s history. And it will happen again. Meet our future supercontinent home, Amasia, and learn what it will look like.

Meanwhile, as California waits for the Big One, geologists discover that major earthquakes come in clusters. Also, our planet is not the only solar system body with tectonic activity. Icy Europa is a mover and shaker too.

And why is land in the western part of the U.S. literally rising up? Mystery solved!

Big Picture Science for Monday 15 September 2014 - Skeptic Check: Is It True?

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: Is It True?

We often hear fantastic scientific claims that would change everything if true. Such as the report that algae is growing on the outside of the International Space Station or that engineers have built a rocket that requires no propellant to accelerate. We examine news stories that seem too sensational to be valid, yet just might be – including whether a killer asteroid has Earth’s name on it.

Plus, a journalist investigates why people hold on to their beliefs even when the evidence is stacked hard against them – from skepticism about climate change to Holocaust denial. And, why professional skeptics are just as enamored with their beliefs as anyone else.

Big Picture Science for 08/18/14 - Moving Right Along

Image for Big Picture Science weekly radio show
Big Picture Science - Moving Right Along

You think your life is fast-paced, but have you ever seen a bacterium swim across your countertop? You’d be surprised how fast they can move.

Find out why modeling the swirl of hurricanes takes a roomful of mathematicians and supercomputers, and how galaxies can move away from us faster than the speed of light.

Also, what happens when we try to stop the dance of atoms, cooling things down to the rock bottom temperature known as absolute zero.

And why your watch doesn’t keep the same time when you’re in a jet as when you’re at the airport. It’s all due to the fact that motion is relative, says Al Einstein.

Big Picture Science for 07/21/14 - A Stellar Job

Image for Big Picture Science weekly radio show
Big Picture Science - A Stellar Job

The stars are out tonight. And they do more than just twinkle. These boiling balls of hot plasma can tell us something about other celestial phenomena. They betray the hiding places of black holes, for one. But they can also fool us. Find out why one of the most intriguing discoveries in astrobiology – that of the potentially habitable exoplanet Gliese 581g – may have been just a mirage.

Plus, the highest levels of ultraviolet light ever mentioned on Earth’s surface puzzles scientists: is it a fluke of nature, or something manmade?

And a physicist suggests that stars could be used by advanced aliens to send hailing signals deep into space.

Guests:
  • Paul Robertson – Postdoctoral fellow, Penn State Center for Exoplanets and Habitable Worlds
  • Mike Joner – Research professor of astronomy at Brigham Young University
  • Nathalie Cabrol – Planetary scientist, SETI Institute

Big Picture Science for 06/23/14 - What Do You Make Of It?

Image for Big Picture Science weekly radio show
Big Picture Science - What Do You Make Of It?

You are surrounded by products. Most of them, factory-made. Yet there was a time when building things by hand was commonplace, and if something stopped working, well, you jumped into the garage and fixed it, rather than tossing it into the circular file.

Participants at the Maker Faire are bringing back the age of tinkering, one soldering iron and circuit board at a time. Meet the 12-year old who built a robot to solve his Rubik’s Cube, and learn how to print shoes at home. Yes, “print.”

Plus, the woman who started Science Hack Day … the creation of a beard-slash-cosmic-ray detector … the history of the transistor … and new materials that come with nervous systems: get ready for self-healing concrete.

(Photo is a model of the first transistor built in 1947 at the Bell Telephone Labs in New Jersey that led to a Nobel Prize. Today’s computers contain many million transistors … but they’re a lot smaller than this one, which is about the size of a quarter. Credit: Seth Shostak.)

Big Picture Science for 04/14/14 - That's Containment!

Image for Big Picture Science weekly radio show
Big Picture Science - That's Containment!

ENCORE: We all crave power: to run laptops, charge cell phones, and play Angry Birds. But if generating energy is easy, storing it is not. Remember when your computer conked out during that cross-country flight? Why can’t someone build a better battery?

Discover why battery design is stuck in the 1800s, and why updating it is key to future green transportation (not to mention more juice for your smartphone). Also, how to build a new type of solar cell that can turn sunlight directly into fuel at the pump.

Plus, force fields, fat cells and other storage systems. And: Shock lobster! Energy from crustaceans?

Big Picture Science - Since Sliced Bread

Happy Birthday, World Wide Web! The 25-year-old Web, along with the Internet and the personal computer, are among mankind’s greatest inventions. But back then, who knew?

A techno-writer reminisces about the early days of the WWW and says he didn’t think it would ever catch on.

Also, meet an inventor who claims his innovation will leave your laptop in the dust. Has quantum computing finally arrived?

Plus, why these inventions are not as transformative as other creative biggies of history: The plow. The printing press. And… the knot?

And, why scientific discoveries may beat out technology as the most revolutionary developments of all. A new result about the Big Bang may prove as important as germ theory and the double helix.

Big Picture Science for 03/24/14 - Do the Math

Image for Big Picture Science weekly radio show
Big Picture Science - Do the Math

ENCORE: One plus one is two. But what’s the square root of 64, divided by 6 over 12?* Wait, don’t run for the hills! Math isn’t scary. It helps us describe and design our world, and can be easier to grasp than the straight edge of a protractor.

Discover how to walk through the city and number-crunch simultaneously using easy tips for estimating the number of bricks in a building or squirrels in the park. Plus, why our brains are wired for finger-counting … whether aliens would have calculators … and history’s most famous mathematical equations (after e=mc2).

*The answer is 16

Image for Big Picture Science weekly radio show
Big Picture Science - Before the Big Bang

ENCORE: It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that!

What happened before the Big Bang? It’s the ultimate prequel.

Plus – the Big Bang as scientific story: nail biter or snoozer?

Big Picture Science for 01/20/14 - Forget to Remember

Image for Big Picture Science weekly radio show
Big Picture Science - Forget to Remember

You must not remember this. Indeed, it may be key to having a healthy brain. Our gray matter evolved to forget things; otherwise we’d have the images of every face we saw on the subway rattling around our head all day long. Yet we’re building computers with the capacity to remember everything. Everything! And we might one day hook these devices to our brains.

Find out what’s it’s like – and whether it’s desirable – to live in a world of total recall. Plus, the quest for cognitive computers, and how to shake that catchy – but annoying – jingle that plays in your head over and over and over and …

Image for Big Picture Science weekly radio show
Big Picture Science - Some Like It Cold

We all may prefer the goldilocks zone – not too hot, not too cold. But most of the universe is bitterly cold. We can learn a lot about it if we’re willing to brave a temperature drop.

A chilly Arctic island is the closest thing to Mars-on-Earth for scientists who want to go to the Red Planet. Meanwhile, the ice sheet at the South Pole is ideal for catching neutrinos – ghostly particles that may reveal secrets about the nature of the universe.

Comet ISON is comet ice-off after its passage close to the Sun, but it’s still giving us the word on solar system’s earliest years.

Also, scientists discover the coldest spot on Earth. A champion chill, but positively balmy compared to absolute zero. Why reaching a temperature of absolute zero is impossible, although we’ve gotten very, very close.

Guests:
  • Francis Halzen – Physicist, University of Wisconsin-Madison, principal investigator of The IceCube Neutrino Observatory
  • Ted Scambos – Glaciologist, lead scientist, National Snow and Ice Data Center, University of Colorado

Find out why cold fusion is a premier example why you shouldn’t hold a press conference before publishing your results. Also, how to separate fumbles from faux-science from fraud.

Plus, why ignorance is what really drives the scientific method.

And our Hollywood skeptic poses as a psychic for Dr. Phil, while our Dr. Phil (Plait) investigates the authenticity of a life-bearing meteorite.

Big Picture Science for 10/28/13 - Shutting Down Science

Image for Big Picture Science weekly radio show
Big Picture Science - Shutting Down Science

“Sorry, closed for business.” That sign hung on doors of national laboratories when the US government shut down. What that meant for one Antarctic researcher: her critically important work was left out in the cold.

So just what do we lose when public funds for science fade? The tools for answering big questions about our universe for one, says a NASA scientist … while one of this year’s Nobel Prize winners fears that it is driving our young researchers to pursue their work overseas.

Yet one scientist says publically funding isn’t even necessary; privatizing science would be more productive.

Plus, an award-winning public-private research project changes the way we use GPS … and a BBC reporter on the fate of international projects when Americans hang up their lab coats.
