    Episode 678: Q&A 126: When Did Mars' Dynamo Shut Off? And More...

    In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. How long did Mars planetary dynamo take to turn off? Could we find and repair the lunar rovers?


    00:00 Start
    00:12 Would extraterrestrial life have any impact on us?
    03:01 When did Mars shut down?
    05:16 Could the rovers be repaired?
    07:05 Would an ejected star take its planets with it?
    08:54 Dangerous to go to Mars at the same time?
    10:19 Is there any way to go faster?
    13:37 Should the smallest black holes already have evaporated?
    15:48 Shouldn't Voyager be coming back?
    17:15 Could there be life inside Jupiter?
    18:50 Does the Sun have a binary black hole partner?
    19:57 Aren't I on vacation?

    Episode 677: Q&A 125 Can Stars Orbit So Close They're Touching? And More...

    In this week's questions show, I explain how it's possible for stars to orbit so closely they're actually touching. What are the limits to gravitational slingshots, and how astronomers know where to point their telescopes in the Universe.


    00:00 Start
    00:44 Can stars touch?
    02:39 What is the maximum slingshot speed?
    05:32 How do astronomers know where to look?
    08:27 Could a planet orbit backwards?
    10:56 Will nations allow deadly space lasers?
    13:06 What if a black hole stopped rotating?
    15:06 How would you control a warp drive?
    17:32 Is Planet 9 a captured rogue planet?
    21:36 Does this mean there are new physics?
    25:08 How common are supernovae that don't leave a remnant?
    27:14 Why would red dwarf planets be tidally locked?
    28:54 How do space agencies decide to launch missions?

    Episode 676: Lunar Rovers. From Apollo to Artemis

    Episode 676: Lunar Rovers. From Apollo to Artemis

    When the Apollo astronauts first landed on the Moon, they couldn’t go far on foot. That’s why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science.


    Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it’s considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon.

    Episode 675: Q&A 124: Are We Even Mentally Capable of Understanding the Universe? And More...

    In this week's questions show I explain why it's still important to do science, even if it's difficult, can we use multiple methods to measure distance, and why the Trojan asteroids don't collect into a single object?


    00:00 Start
    00:40 Why should we bother trying to understand the Universe?
    05:01 Can different methods be used to measure distances to the same object?
    07:50 Why don't Trojans collect into a single object?
    10:24 Split the videos up?
    13:02 Do supernovae cause a chain reaction?
    14:27 Why settle the Milky Way?
    16:48 What if a black hole came close to the Earth?
    18:04 Is there an escape velocity from the Milky Way?
    18:51 Could we detect something moving faster than light?
    20:48 Could we detect pulsars in other galaxies?
    22:44 When does a planet end, and an atmosphere begin?
    24:06 Could we store photons for energy?

    Episode 674: A Massive Star Just Disappeared. No Supernova, Just Straight to Black Hole

    Episode 674: A Massive Star Just Disappeared. No Supernova, Just Straight to Black Hole

    When the largest stars die, it’s usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it just… vanished?


    Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it?

    Episode 673: A New Way to Measure The Expansion of the Universe. The Cosmological Crisis Deepens.

    Episode 673: A New Way to Measure The Expansion of the Universe. The Cosmological Crisis Deepens.

    This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe.


    You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Fantastic!

Fraser’s Q&A episodes are fun and educational. I find myself listening to each one several times. This is quality programming at its best.
