    Episode 699: Open Space 96: The End of the International Space Station? And More...

    In this week's Open Space, we had a series of questions about the International Space Station. How long will it remain in orbit, and what role will it continue to play with other space stations under construction? We also talked about how much longer the Earth will remain habitable, and if it could be possible to replace Arecibo.


    00:00:00 Start
    00:03:35 How much longer with the Earth be habitable?
    00:06:30 The great conjunction
    00:09:11 Is nuclear power a good option in space?
    00:13:31 What is the future of the ISS?
    00:18:24 What are the chances of replacing Arecibo?
    00:21:57 Couldn't we melt down the station for raw material?
    00:23:35 What do I think of Axiom's private space station?
    00:27:28 What's the best supernova candidate?
    00:32:25 Could we add mass to Mars to restart its core?
    00:36:03 Am I excited about the next Gaia release?
    00:40:45 Are we looking backwards in time?
    00:42:00 How's Chinese going?
    00:46:39 What's the future of the Thirty Meter Telescope?
    00:50:24 Will there be more international collaboration?
    00:54:45 How much of the Universe has already disappeared?
    00:56:33 Future telescope names?
    00:57:00 Legit warp drive?
    00:59:45 Any value putting a telescope on Mars?

    Episode 695: Q&A 130: Does the Dark Forest Explain the Fermi Paradox? And More...

    In this week's questions show, I talk about the Dark Forest theory in the Three-Body Problem series of books. Is it a compelling answer to the Fermi Paradox? How much of a risk is dust to interstellar travel? Is black hole evaporation negated by black holes absorbing additional material and energy?


    00:00 Start
    00:46 Is the Dark Forest a reasonable answer to the Fermi Paradox?
    04:05 How much dust is in interstellar space?
    05:57 Can we go faster than the Voyagers?
    08:24 Are black holes gaining mass faster than they're evaporating?
    10:07 Is abiogenesis happening right now?
    13:47 How do we calculate the habitable zones around other stars?
    15:45 How close can binary stars be and still be habitable?
    17:50 Could we find debris in the Lagrange Points?
    19:27 Can gravitational waves let us see past the CMB?
    22:07 What is a galactic halo?
    23:49 Are there gas dwarfs?


    Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here.
