    Episode 754: Q&A 152: Could We Detect Dyson Swarms? And More...

    In this week's questions show, I explain why Dyson Spheres (and Swarms) should actually be pretty easy to detect across the Universe. If it's possible to service the Hubble Space Telescope with a Falcon 9, and will computers take jobs away from astronomers.


    00:00 Start
    01:04 How could we detect Dyson Swarms?
    07:24 How could we hide a Dyson Swarm?
    10:03 Could a Falcon 9 service Hubble?
    13:02 Will computers replace humans in astronomy?
    16:30 Will any Venus missions be able to detect life?
    18:43 Could you generate repeating gravitational waves?
    20:25 What conventional wisdom will be disproven by science?
    23:43 How much longer will Earth be habitable?
    26:08 What will drive space exploration?
    28:15 Will James Webb let us see more Universe?
    29:27 What do I think about the similarity between cosmic filaments compared to the CMB?
    30:27 What are some future propulsion systems?

    Episode 753: Interview: Prof. Lee Cronin - Detecting the Chemistry of Life

    My guest today is Professor Lee Cronin from the University of Glasgow. Dr. Cronin investigates the chemistry of life and has developed methods that could help us detect it on other worlds - even life as we don't know it.

    Episode 752: Q&A 151: Would They Warn Us About the End of the World? And More...

    In this week's questions show, I explain what would happen if scientists discovered an existential threat to humanity. Would they let us know, or keep it secret to avoid a panic? Could we detect a Breakthrough Starshot fleet coming our way? And how well does China communicate its space exploration to the public?

    00:37 Would they tell us about the end of the world?
    03:05 Is the Solar System normal?
    05:38 Could we detect Breakthrough Starshots?
    08:46 How well does China communicate to the public?
    11:15 Could we use space junk for 3D printing?
    14:02 What do I suggest for aspiring astrophysicists?
    17:11 Will there ever be another Grand Tour?
    19:47 What determines a planet's orbit?
    22:08 Will Blue Origin pick up the pace?
    25:02 What if aliens were pure energy?
    28:14 Should there be more dark matter inside planets?
    29:39 Would alien life be multicellular?

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!
