    Episode 750: Q&A 149: What if a Microscopic Black Hole Passed Through the Earth? And More...

    In this week's Q&A, I try to imagine what might happen if a microscopic black hole passed through the Earth. How long will James Webb take to become operational, and what will be the Plan B for James Webb if it fails?


    00:00 Start
    00:46 What if a microscopic black hole passed through the Earth?
    05:25 When will James Webb come online?
    06:38 What's plan B for James Webb if it fails?
    09:16 Do Oort Clouds overlap?
    11:29 Could there be a Tatooine out there?
    13:50 Does China plan to colonize Mars?
    16:22 Does the US take China's space exploration seriously?
    19:50 Are there dark matter planets, suns and people?
    22:11 What will the US government disclosure tell us?
    25:45 Should I get an astronomy degree?
    30:19 Shouldn't there be more black holes at the center of the Milky Way?
    32:03 Have we measured the speed of gravity?
    33:13 Will AI explore the Universe without us?

    Episode 747: Q&A 147: The Night Sky at the Center of the Milky Way? And More...

    In this week's questions show, I consider what the night sky might look like if you could stand at the center of the Milky Way where the stars are denser. Do all stars have Oort clouds? And could Starship really send humans to Mars for the price of a house?


    00:00 Start
    00:50 What would the sky look like at the center of the Milky Way?
    04:05 Will the Neutron be competitive?
    07:40 Do all stars have Oort Clouds?
    09:59 Would it be realistic to send humans to Mars for the price of a house?
    11:38 Next cool space mission I'm excited about?
    13:20 Do I think there's microbial life in the Universe?
    16:48 How far away was the Big Bang?
    19:26 Why was L2 chosen for JWST?
    21:52 Does SpaceX need NASA?
    25:11 Would Starlinks be brighter if they were lower?
    28:21 Multiple nukes to destroy an asteroid?
    30:21 Could we make a telescope the size of Earth's orbit?

Better than StarTalk

I love the show gets a deal strictly with Astronomy and not some stupid comedians and everything else sports StarTalk used to be great but now it’s going downhill fast.Fraser is a great host and I love the show and astronomy podcastWith cohost Pamela Gray

CaedH ,

Has Taken Over StarTalk

Like I have seen with some people here, I have moved here from StarTalk which has been gradually becoming more comedic. They have started to run out of ideas and don’t know how to deal with it. So far, with this podcast, I have not seen any of that loss of idea. Always has something to talk about and always goes into great depth. Love it!

John from Fresno ,

Long Time Follower of Universe Today

The host is well-known in astronomy and science circles— Mr. Fraser Cain smartly hosts a ‘multi-media pronged’ endeavor that gives astronomy a sense of popularity and a new sense of purpose. Not since Carl Sagan— can I think of someone who has elevated science to a sense of purpose that many of us could follow as a template. Take you Fraser!
