Randy and Jim talk about the strange results of the ANITA experiment: tau neutrinos that seem to come up out of the Earth.

August 16, 2020 06:00 PM PDT

Randy tells Jim about ways in which electromagnetism reduces the gravitational attraction caused by a body.

July 07, 2020 06:59 PM PDT

Jim and Randy discuss the hypothesis of sterile neutrinos, neutrinos that are even more ghostly than neutrinos that are dark matter candidates.

June 09, 2020 06:28 PM PDT

Jim and Randy talk about gravitational waves.

May 03, 2020 03:17 PM PDT

Jim and Randy discuss a possible "fifth force," the hypothetical X17 particle that has been seen in several experiments.

Erratum: The g-2 of the muon was shown to be off by 1 part in 500,000 in 2001 at Brookhaven. It may not be in there, I'm not sure how much of that I cut out.

Jim and Randy discuss the apparent creation of quanta seen by comparing the viewpoints of relatively accelerating observers -- the Unruh Effect.

(There is a little noise that shows up on Randy's track half way through - I did my best)

Randy introduces Jim to the Gertsenshtein effect, the conversion of gravitational waves to electromagnetic waves through resonances.

November 23, 2019 09:02 PM PST

Randy introduces Jim to Sabine Hossenfelder's bimetric theory of gravity. In this gravitational theory, there are two types of matter whose only interaction is through gravitation. However, each one reacts to space-time differently, resulting in different metric tensors for each. In low-curvature situations, this creates a kind of anti-gravitation.

September 21, 2019 07:35 PM PDT

Randy and Jim discuss experiments that purport to show that there is no such thing as objective reality.

August 16, 2019 03:32 PM PDT

Jim and Randy discuss loop quantum gravity, and integration of quantum mechanics and gravity that quantizes space-time itself through the use of uncertain quanta of volumes and the random connections between them.

take it with you

Iphone_trans Listening to podcasts on your mobile devices is extremely convenient -- and it's what makes the podcasting medium so powerful.

You can take your favorite shows and mixes with you anywhere, but to do so requires some quick and simple steps.

Let's walk you through that process together.
step 1:

Click the "Subscribe With iTunes" link in the page's sidebar:


This will require that you have the iTunes software on your computer.

(You can download iTunes here.)
step 2:

Now that you've subscribed to the podcast on iTunes, the feed will display in your "Podcasts" section on the left navigation bar.

Click there and you'll see the show displayed in the iTunes browser.

You can "get all" to download all available episodes or just individual episodes.
step 3:

Plug your mobile device (iPhone, iPad, iPod) into your computer with the Dock Connector cable, and click the device in iTunes's left navigation bar.


Once you have your device highlighted, click "Podcasts" in the top navigation bar and sync the podcasts you want on your device. Click "apply" and the episodes you have downloaded on your iTunes software will sync with your device.
that's it!

The beauty of this process is that now, every new episode of your subscribed podcasts will automatically sync to your device every time you plug it in and open iTunes. You can now take your favorite shows with you everywhere you go.
