That was fantastic, a caffeine-fueled, high-powered look into the future - thanks once again, Pamela & Fraser! Let's hope that all predictions come through. Well, at least the good ones!

Pamela is at a conference, so we're going to record later today than usual!

Join +Fraser Cain  and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions!

Ep. 397: A Universe From Nothing

One of the biggest, most basic questions you can ask is: “why is there something and not nothing?” The reality is that we don’t know the answer, we might never know the answer. Let's probe to the edge of what we can explain, and what ideas cosmologists have proposed to explain how we all got here.

+Pamela L. Gay +Fraser Cain  question about the age of the universe been 13.8±1.2 Billion years.  If time is relative to the observer, is that the estimate as observed from this planet?  How will it be different if observed from orbiting satellites or even from another galaxy?

Ep. 395: The Standard Model - Baryons and Beyond

 In the last few episodes, we’ve been talking about the standard model of physics, explaining what everything is made up of. But the reality is that we probably don’t know a fraction of how everything is put together. This week we’re going to talk about baryons, the particles made up of quarks. The most famous ones are the proton and the neutron, but that’s just the tip of the baryonic iceberg. And then we’re going to talk about where the standard model ends, and what’s next in particle physics.

With the extra episode Pamela & Fraser did a couple weeks ago with Paul Matt Sutter the +365 Days of Astronomy schedule for Astronomy Cast rebroadcasts has shifted a week. So this episode will be featured on Dec 14th. Free on iTunes, of course. :^D

Let's try this again!

Join +Fraser Cain  and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for another episode today!

Ep. 393: The Standard Model, Leptons & Quarks

Physicists are getting a handle on the structure of the Universe, how everything is made of something else. Molecules are made of atoms, atoms are made of protons, neutrons and electrons, etc. Even smaller than that are the quarks and the leptons, which seem to be the basic building blocks of all matter.

Today's Astronomy Cast is our first time trying the YouTube Live version of video, so you should be able to see it here! If anything goes wrong, Fraser and Pamela will direct you where to go to watch! Isn't new tech fun?

Watch us here today! ~Susie

Hi!  Been enjoying the show for some time - hopefully, I'll be able to join live, for the first time, for the 400th episode...which should fall on the 18th, a holiday for the US that at least we public servants get paid time off.

I have a question, though:  why, on #398, did you guys include sodium vapor lamps, fluorescent lamps, and neon signs in the "emitting" group, but not in the "ionizing" group?  All three are ionizing sources, where the light we see is due to very narrow, discrete emission lines characteristic of the elements being excited by the plasma.  Fundamentally no different from auroras and streaking meteors, where those natural phenomena get their energy from the kinetic energy of the CME or the meteor, while the artificial sources are jump-started by a few kilovolts of electricity.

Ep. 394: The Standard Model, Baryons

All fundamental particles are either fermions or bosons. Last week we talked about quarks, which are fermions. This week we'll talk about bosons, including the famous Higgs boson, recently confirmed by the Large Hadron Collider.

You could interview astronomers at your local University, perhaps, and let them carry the day! :^D
