JMG is a legend.
Taking us to the edge of the galaxy and on a fantastic voyage through a parallel universe, one video at a time.

Your work has gotten me through some very long, hard nights and times; it's doing it right now. Thank you.

JMGs worst fear is that hyperadvanced aliens will come down and tell us everything we want to know about the universe. There wouldn't be any content left for his channel.

Extraterrestrial civilizations could be right under our galactic "nose" but could be communicating using means unknown or purely theoretical to us. I've always thought of those SETI programs looking for radio signals as overall a good for humanity, yet akin to trying to read smoke signals set off in the Himalayas from the Andes.

There is absolutely no reason for this man to not have 1 million plus subs. GRADE A CONTENT MY DUDE.

Another great video, John.
Thank you for the intellectual stimulation. 😊

Thank you for mentioning the actual FIRST exoplanets that were discovered by Wolszczan and Frail.
They often get undeservedly overlooked in favor of the first exoplanet discovered around a Sun-like star.

I would love your take on Quantum Immortality

Sincerely, thanks a lot for explaining astronomy in such precise and professional way, and for taking questions like alien life and the UFO question with seriousness. Your insights are very good, and you explain and discuss this subjects very well to people like me who aren't from the realm of astronomy or physics in general.

Your videos are the BEST!!! …in which we

There is something special about listening to this or an Art Bell show.. there's that magical energy that happens after midnight.. i remember being a little kid and listening to Art Bell then about 6 or 7 years ago Secureteam10 use to be on a roll for a couple years.. now its the John Michael Godier period.

I get very excited anytime a new video from JMG drops. It's my highlight of the day.

[nickpricey]

I absolutely love both of this man's channels. I find it mind-blowing topics about space.

[bkillinm]

Your videos are quite possibly some of the best on YouTube thanks John we appreciate you!

[xYalz]

Been listening to your videos every morning at work at 4 am. Thanks for keeping me entertained during the sleepiest and worst hours.

[jodanskifugazi]

Appreciate all the content lately, cheers John.

I’m always so excited to see your new videos

I still feel like the answer to both the Fermi "Paradox" and all these other questions on life in the universe could most easily be answered by acknowledging the ability for heavy elements to form in substantial quantities was relatively recent.

We have some very specific needs for certain elements which can only be formed after several generations of stars have come and gone. I think we are probably one of the earliest planets to form life, let alone to have enough time for that life to evolve to us. Obviously there could easily be other planets that are a billion years our elder, but I think those would be much less common than the nunber of planets that have yet to form.

And even if it's not a widely accepted concept, I also believe that there's some chance that there were much older human (or hominid) civilizations that have been erased from the archeological record, possibly even those that fled the planet before a catastrophic event (like the Younger-Dryes "event(s)." Maybe those are the UFO/UAP we've seen so much about. And maybe they were just checking back in on their descendants.

But in any case, I think it's highly likely that we are very early to the "civilization" thing. Maybe the conditions for advanced civilizations are an extremely recent step in the universe's evolution. In that case, there will be tons of civilizations that form later down the line (and far away) that will see our techno-signatures and begin to try to make contact, no realizing that we went extinct millions of years before their messages reach this pile of ash.

The world is a better place with frequent JMG uploads. Seriously, thank you

Your narration and scientific depth far exceeds that of the majority of professional production scientific documentaries that are surface level. Outstanding work
