Complementary Views: Astrophysics & Alien Tech | Avi Loeb, David Sobral & Mikhaila Peterson Podcast

In this episode, Mikhaila had two different guests to discuss an intro to astrophysics and potentially alien life.

David Sobral is a Portuguese extragalactic astrophysicist and lecturer, best known for the discovery of galaxy CR-7. He illustrates the complexities of many basic principles such as gravity, time-space nuclear fusion, and more.

Abraham “Avi” Loeb is an Israeli-American theoretical physicist and author of the recent book “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.” His controversial book explores the recent discovery of an object named Oumuamua that moves and defies the realities of everything we have seen in our solar system to date.

    This space dude has some great theories and I’m sure he sees the universe in a lot more detail than most people but his explanation of gravity sounds like space junk.

  3. Di Dinx on April 13, 2021 at 6:36 am

    Lancaster University….my old Alma Mater! Excellent podcast btw.

  4. Mic Le Wat on April 13, 2021 at 6:37 am

    I really enjoyed this, universe for dummies like me. Thank you

  5. Rebe Bristol on April 13, 2021 at 6:38 am

    Love it Mikhaila! Thanks so much!

  6. Mike Lipschitz on April 13, 2021 at 6:38 am

    Mikhaila hi ,u prob don’t read this ,but you are a totally fascinating person and brilliant interviewer .I am exceptionality well educated and writing my 3 rd book .So bad reviews and rude comments as prob know are very sad disturbed people who unless for humanitarian reasons most reasonable people wouldn’t have time for .Keep up your incredible work and like and I hope you sift your health stuff out .Thanks for your work and efforts Mike

    Hey, let’s do math, that is not actually relevant to reality. Then, let’s translate it into vague descriptions that aren’t actually logical and convince people we are on the right track.
    Ooohh, let’s use UNDEFINED words and terms to sound smarter and obfuscate that we actually have no idea what we are talking about. It will sound cool though.

  8. Louise Taylor on April 13, 2021 at 6:41 am

    Mikhaila, I am a big fan but I think you need to be more knowledgeable.. at least the basics .. about a subject just to make it more interesting .. love and a hug 🤗

  9. Bob van Butselaar on April 13, 2021 at 6:42 am

    Dark Matter Matters! 😉

  10. Dan Howard on April 13, 2021 at 6:45 am

    I love Avi Loeb. It’s a great book!

  11. Sorgutentarer on April 13, 2021 at 6:45 am

    Mikhaila JUST GOOGLE IT! 😀

  12. Markus Heinonen on April 13, 2021 at 6:46 am

    Excellent concept

  13. Oumuamua Today on April 13, 2021 at 6:47 am

    Great interview Mikhaila.

  14. Basa Pete on April 13, 2021 at 6:47 am

    Great job, Mikhaila! Astrophysics is a very interesting subject.

  15. galaxytrio on April 13, 2021 at 6:47 am

    Both men interviewed were interesting _and_ charming.

  16. Fapnado on April 13, 2021 at 6:49 am

    Watch the Suspicious0bservers playlists on the upcoming extinction event on earth. Also Diehold Foundation’s playlist on extinction events, ice ages etc. Its coming soon (most likely).

  17. Yoda Wise on April 13, 2021 at 6:49 am

    I love this topic!

  18. TimC Cambridge on April 13, 2021 at 6:49 am

    I guess we assume technological advance has primacy over a naturally biospheric cosmic Nature?

  19. Jason koch on April 13, 2021 at 6:50 am

    A stunning, hugely intelligent woman and some of the world’s leading minds… how can that formula fail? Great podcast. 👏

  20. Alan Erkkila on April 13, 2021 at 6:53 am

    That was so cool! Both of these guys are engaging and informative… enthusiastic, and even fun! I expected Avi to be a crackpot, but he’s not! He’s quite reasonable!

    So, great show, Mikhaila! I loved it! Barbie doesn’t hold a candle to you!

  21. collabthem on April 13, 2021 at 6:55 am

    Charles Hoskinsons please! #Cordano

  22. Roger Rabbits on April 13, 2021 at 6:55 am

    This style and opposing views I enjoy

  23. Alex Mitchell on April 13, 2021 at 6:55 am

    It’s so weird seeing one of our lecturers on this podcast. My worlds have collided

  24. Mana Loola on April 13, 2021 at 6:56 am

    So… like, space is a thing? Like, it’s not nothing? Like, it’s a thing that can be bent?

  25. Cloxygen on April 13, 2021 at 6:56 am

    but we only fall down slopes because of gravity
    so if gravity is a slope does it have its own gravity?

  26. Sfer Tonoc on April 13, 2021 at 6:56 am

    Hmmm… Cartesian minds cannot figure.

  27. MarvAlice on April 13, 2021 at 6:58 am

    hot take: there is no such thing as extraordinary evidence, or extraordinary claims. there is just claims, and evidence. something has either enough evidence, or too little. the mythical category of "extraordinary evidence" exists exclusively to justify to one’s self why one feels a given amount of evidence is too little while others consider it to be enough.

  28. bakavasa on April 13, 2021 at 7:00 am

    My question is how does he know there will be more of these with such certainty that he would like to see a satellite sent to the orbit to take a photo of the next one? If this was the first such object ever, why does he expect another one to come shortly?

  29. 64kdwg on April 13, 2021 at 7:01 am

    Please get Elon! 🙏🔥🇨🇦

  30. Hemp Wick on April 13, 2021 at 7:02 am

    I hope Mikhaila pulls a Lex Fridman and just goes all in on the podcasting non-stop. Release a few courses and affiliate links along with that YouTube ad revenue and you’ll make a $million/year.

  31. Jeffrey Browy on April 13, 2021 at 7:03 am

    Great format. I like complimentary interviews.

  32. stenobro on April 13, 2021 at 7:04 am

    Man, that Avi guy was really easy to listen to.

  33. Kryptic Kodex on April 13, 2021 at 7:04 am

    Okay this is awesome 😎

  34. Katie Abrahams on April 13, 2021 at 7:07 am

    I think black holes take us to the afterlife, or a new life cycle at least

  35. Courtney Wiley on April 13, 2021 at 7:07 am

    Mikhaila I absolutely love how honest and open you are…definitely not a pouting Barbie, but just a beautiful young woman trying to connect and understand things beyond her immediate world. Thank you for all you do 🙏

  36. ramiro costa on April 13, 2021 at 7:08 am

    cool shit david. nice interview!

  37. Psychology Related on April 13, 2021 at 7:11 am

    Great pod 👏

  38. jimmy white on April 13, 2021 at 7:11 am

    People going missing in national parks. That would be a good topic. Really weird stuff has been going on

  39. justice peace on April 13, 2021 at 7:12 am

    lovey dulcet tones in her voice.

  40. Sequins on April 13, 2021 at 7:14 am

    Super cool idea for a podcast

  41. Jonathan Hughes on April 13, 2021 at 7:18 am

    Pretend of space like it’s water you live in and you just don’t see it. I do wonder if a fish see’s water. Comets and Asteroids are pretty much the same. She’s getting astrophysics for beginners. Black hole is not really a hole. No one really knows what it is.

  42. Intercaust on April 13, 2021 at 7:18 am

    The bangs gotta go. Love you and your fam!

  43. Jonathan Hughes on April 13, 2021 at 7:20 am

    What he thinks is alien tech, but I don’t doubt it is.

  44. Jay Adams on April 13, 2021 at 7:22 am

    Avi Loeb had me like a kid at at the dinner table fascinated, he was very interesting.
    Great job mikhaila! I liked the style of this podcast, I also liked the style of the carnivore anecdotes podcast!
    Well done…….your killin it ! 😊

  45. John Enockson on April 13, 2021 at 7:24 am

    Avi is being very shallow in describing basic astrophysics maybe tailored for his host or just not that good at communicating.

  46. Mariann Warner on April 13, 2021 at 7:25 am

    Don’t worry about them finding us – they’re already here and have been for some time now!!! 👽

  47. FreedomFisher on April 13, 2021 at 7:26 am

    5:30 "If you are REALLY MASSIVE it bends a lot".
    I’m not fat, I’m a professional space-time bender!

  48. oriana garrido on April 13, 2021 at 7:30 am

    What’s a Wormhole?
    of course he would grab the paper.. fold it and then put a pencil thorugh it 😆

  49. Adriana Vata on April 13, 2021 at 7:31 am

    That’s fooking crazy 19:50

  50. 3runrob on April 13, 2021 at 7:31 am

    Hey Michaela there’s an interesting video about benzodiazepine withdrawals that you might find useful by a channel called leo and longevity
