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

    • Astronomy

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?
