    Episode 709: Q&A 132: How Much Of The Universe Could We Ever Explore? And More...

    In this week's live Q&A, I talk about the new Space Launch System hot-fire test, how Breakthrough Starshot spacecraft might be able to communicate with home, and what messages would we send to aliens that we might never be able to reach physically.


    00:00 Start
    02:11 How would Starship chipsats communicate with Earth?
    05:00 How far can we ever explore into the Universe?
    06:31 Why was the SLS test so short?
    08:59 This is why we test.
    09:52 What message would we send to aliens we could never visit?
    13:52 Is anyone working on a practical artificial gravity?
    18:32 Do we know which stars can see Earth transiting?
    21:11 How do spacecraft change their trajectories?
    23:50 When will LUVOIR launch?
    26:24 Why is there a solar cycle?
    29:51 Will AI start answering science questions?
    32:53 Is a generation ship or seed ship better?
    35:25 Are gravitational lenses like telescope lenses?
    36:46 Will we hit light speed or wormholes first?
    37:49 How prepared are we for a Carrington Event?
    40:48 Can we predict gamma ray bursts?
    45:52 What are my news sources?
    48:41 Do I think there's non-intelligent life out there?
    52:56 Would a Europa lander see any life in the surface?


    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.

    Episode 704: Interview: Elizabeth Howell PhD, Canada's Role in Space Exploration

    My guest this week is the science journalist Elizabeth Howell. Dr. Howell is one of the most prolific space journalists working in the field, contributing thousands of articles across almost every space news site (including Universe Today).


    She has also written and collaborated on several books. Her latest book is called "Canadarm and Collaboration", and it's all about Canada's role in spaceflight.
