[Q&A+] Absent Planets from Our Solar System, Interstellar Black Holes, Non-Conventional Theories | Q&A 333

Shockingly the YT algorithm almost exclusively suggests things that match what I want and when it suggests a channel or video I haven't watched before, it still fits within my perspectives - channels that care about science, space, nature, true truth, compassion, fighting for the vulnerable people and environmental stewardship, etc. I never get AI schlop or stuff like Joe Rogan lol. I have been "curating" my online presence for a very long time since I'm kind of old myself hehe.

My Earthly mind experiment that may explain Fermi Paradox despite life and intelligent, technological life abundance: Imagine uncontacted tribe deep in Amazon. They have it good, there is small river just right for resources but not a threat, there are cenotes with clean water, some hills and abundant food and timber... They understand their world in detail, local life maybe better than some biologist... They wonder, "are we alone in the Universe"? They never seen anyone else, they knew that there are distant gigantic rivers and forest fires, hostile world. Hence, they conclude that their little heaven is only livable place to develop long term. They do see occasional plane flying over, explicit evidence of way advanced technological civilization but, they interpret from their myopic view - it flies, it has wings... it is Natural gigantic bird, thankfully not living near by, one more reason that nobody else can exist far away, such great dangers where that bird lives... We are that on Cosmic scale. Undoubtedly we have seen clear evidence of advanced technology far away but explained it away from our limits as just Nature. Fundamental laws of nature point to inevitability of life emerging and evolving, part of which is intelligence and tech. Earthly proof for it - extremophiles everywhere. Yes, there are great filters but even just our galaxy is vast, there are out there, now certainly many technological species. Published study actually suggests that we are latecomers at far edges (they find that civilization boom in Milky Way was millions of years ago far closer to galactic center).

The response to the person asking about their pet theory was great, but the closing thought was the important bit. I don't look at any of the algorithm based feeds unless I'm bored. Then I remember I have cool books to finish.

I’ve curated what I watch by not having any social media. I’ve also eschewed YT. I watch only what I find on my own or was recommended to me by friends/colleagues/family. I only use Nebula, Patreon, Odysee, Curiosity Stream which don’t advertise but do allow me to support creators directly.

Here is a question: are all gas giants so radiation heavy like Jupiter? If so then would it be possible for life to evolve around an Earth like moon orbiting a radiation heavy gas giant?

What about running Vera Rubin for 10 yrs and then moving it to the Northern Hemisphere?

Anyone else watch it live, and still watch the edited version later?

On the subject of alien intelligent life, my thought is that we are alone in the galaxy. If there was a technological civilization out there, they would've evolved billions of years ago and already colonized Earth, thus preventing us from ever existing. Yet we exist. I think there is intelligent life there, but it's like civilization of every few galaxies. On the likelihood of life evolving; I think finding complex life on Europa would be a far greater indicator of what the odds are of life forming than finding life on Mars. Finding life on Mars (unless it is based on a chemistry separate from DNA) could be indicative of panspermia being a thing with life from Earth migrating to Mars or vice versa. Europe being seeded by life from Earth or Mars is exceedingly unlikely considering the kilometers of ice on its surface, so finding complex life there would be a massive discovery.
