Was There A First Cause?
Was there a first cause? Can there be a event that started everything? What would such an event look like? In this episode Tony and Charlotte discuss the scientific and philosophical understanding of the beginning of the universe and what an effect that does NOT have a cause must look like.

When An Atheist Met A Catholic Theologian
This episode kicks off what I hope will be a weekly posting for the DA Show. My wife Charlotte is a Catholic theologian and philosopher who has taught me much outside of my scientific realm. I have heartily enjoyed our conversations over the years and now I hope to share some of them with you.

A Cautionary Science Tale: BICEP2 and the Perils of the Nobel Prize
Remember all the commotion about the BICEP2 mission back in 2014? Cosmologist had announced the observation of polarized "B-mode" waves that, if connected to the universal cosmic microwave background, would lend credence and observational support to the Inflationary Theory of Cosmology, this…

Using Nuclear Power for Deep Space Exploration
It turns out that NASA and others have been thinking about the inefficiencies of using chemical rockets to go to the Moon, Mars and the Outer Planets. One very attractive solution is Nuclear Thermal Propulsion, a technology that was begun in the 1960's and considered as a viable method of...

The Apophis Asteroid: Should You Be Worried?
Let's talk about the potentially hazardous asteroid known as Apophis. In April, 2029 this 320 meter rock will get so close that it will pass under the orbit of geosynchronous satellites! Astronomers held a conference in late April of 2019 to discuss the science that can be done as it passes so...

Just How Fast is the Universe Expanding EXACTLY? ...and how do we know this?
We've known since Edwin Hubble's time that the universe has been expanding. What we've only recently learned (like, in the past 10 years or so) is that the universe is accelerating as it expands. Measuring this expansion rate has been problematic and while there are at least two different ways to...

Life in the Universe? We May Be It!
I'm not convinced that life is everywhere in the cosmos. It is entirely possible, based on what we know today, that we are the only life there is. Anywhere. This episode is a brief discussion of that idea.

-
Using Resources in Space to Sustain Human Exploration
NASA has for decades been assessing options to utilize the resources available in space – often on the Moon and Mars – to sustain long-duration human operations. It will be prohibitively expensive to send from Earth to either location sufficient resources for astronauts to carry out priority...
-
The Thirty Meter Telescope (TMT)
The largest ground-based telescope is now being built on the top of Mauna Kea in Hawaii. The Thirty Meter Telescope (TMT) is a new class of extremely large telescopes that will allow us to see deeper into space and observe cosmic objects with unprecedented sensitivity. The TMT International...

The Origin of Life w/ PZ Myers
Had a great discussion yesterday with biologist PZ Myers about the origin of life on Earth. What is our current knowledge of how life began on our planet? Is life easy or hard to make? We also extend the discussion to life on other worlds.
-
Amazing Astronomy at the European Southern Observatory
The European Southern Observatory (ESO) has been on the forefront of astronomy discovery for decades. They operate telescopes primarily in South America, in Chile, and their astronomers have made groundbreaking observations in exoplanet research, cosmology, black holes, galaxy formation, etc....

Clarke Exobelts: A Technosignature for finding Alien Civilizations
Clarke Exobelts, appropriately named after Arthur C. Clarke, are belts of satellites around and exoplanet that are in a geosynchronous orbit around it. These belts have distinct characteristics that can show up in space telescope transit surveys looking for planets around other stars.

The Search for Planet 9: So, Where is it?
Astronomers believe there is an undiscovered super-Earth Sized planet lurking in our outer solar system. If it exists, then astronomers think it would have an estimated mass of ten Earths, a diameter two to four times that of Earth, and an elongated orbit lasting approximately 15,000 years. So…
