What Will Humanity Do If We Ever Discover Aliens?

I really hope you enjoy this supercut! Parts of 12 different episodes have gone into this one, plus a lot of extra content made specifically for this video. I know this is a very long video, so I'm curious to know how you get on with it, so I can gauge whether I should ever do something like this again in the future. Thanks for watching! Alex

My wife and I are about to celebrate our 55th anniversary. We have set this video as our movie for the night. Thanks for putting this together.

"Temperature can affect size" "I WAS IN THE POOL"

This was really interesting, but the question "What Will Humanity Do If We Ever Discover Aliens?" was barely touched? The title should be: "What we know about-, and how we look for alien life"

1:33:04 this is actually most likely a Boeing 737. The flashing sequence of the lights and flight path at that time both match a certain flight taken by one of those planes.

This has given me nearly 2 weeks of content to fall asleep to. Everytime I go to bed I resume the video to the point I last remember. Theres few things more comforting in my life than being able to watch this channel and a few other similar ones most nights.

Hello Alex, I’m a grandma from Manchester UK and I really enjoy your videos. I think they’re extremely well done and your delivery is perfect for me. You explore and explain things with a direct, clear manner. Plus, I enjoy the topics you share - even in my sixties I still love to learn.

I love space so much dude

Awesome commentary, extremely thought provoking. I have heard a lot of the arguments and theories before but to have them presented together in a well thought out progression was very helpful. Thanks for your hard work, well worth listening to the whole way through, look forward to further content.

Once I understood the scale of the observable universe I came to a realization that discovering or contacting any potensial extra terrestrials was a slim one. Then I also realized the the scale of time and how small we are in that dimension as well. Even within our own galaxy there doesnt seem to be any reasonable setting for us to make any contact with others if they exist, have existed or will exist. In astronomical timescale, we just came into existence and are likely to be just about to vanish. Lets just make sure to fully appreciate the moment as long as it lasts.

This is what creator content is meant to be. Thank you.

Note on the lack of a dynamo for a magnetic field: Tidally locked planets are not without rotation. They do in fact rotate because there would be a night/day cycle based on theplamet's yearly orbit. Tiddal locking is not due to rotation ceasing, but by the rotation matching the orbit around the star. Additionally, due to the close in orbits of a tidally locked planet, its year would be much shorter than our Earth year, potentially only a couple weeks or even a few days. Would this be enough of a dynamo for some, all be it weaker, magnetic field?

We will bring them democracy

Astrum, your voice is so calming that I always try listening to them to go to sleep, the only issue is that the content is so interesting I can’t help but to stay awake so that I can enjoy it in it’s entirety. By far one of my favorite channels man, please keep them coming.

If ants could talk I would be quite interested in what they have to say out of pure curiosity

Great vid!! I found myself nodding in agreement a lot!! However.. consider that galaxies merge regularly and yet there are likely *no*star collisions at all; it’s the infernal *distance that will keep us permanently isolated; us from “them” and them from us

thank you for the incredible work you do

Hey Alex, thank you. I hope you see this and know how much you've helped so many. It's neither here nor there what I, or anyone else is going through, or has been through but your contributions have helped countless people get through some seriously tough times and been a wonderful escape from our struggles here on Earth and pointed our eyes toward the skies. Toward things greater than ourselves and anything we could possibly imagine. Much love, bud.

If we leave it to politicians, something stupid.

this is by far one of the most interesting videos i have ever watched on you tube. THANK YOU.
