I like the space travelers' reaction when they find that they live in a closed Universe.

Awesome explanation!!! That lady's voice is sooo soft and mellow, that you can almost chew and taste her words. Very elocuent and easy to understand. Congrats!!!

Those space chicks were bored shitless with each other after 300 years but they know they have to keep cruising around the universe together... f o r e v e r . . . .

You deserve the title of Richard Feynman for an online educational channel. The perfect combination of animation, physics, philosophy, and excellent illustration has made you one of my favorite channels on YouTube, EugeneKhutoryansky.

I love how you explain difficult substances in simple terms. It is truly a talent! Great job, keep going!

Where can I join this space mission crew?

I was having a group project, and my computer automatically started playing this part loud volume lol 2:18. I didn't notice it until everyone was just staring at me, since I was wearing noise cancel headphones lmao.
But I love your videos though, this is one of my favorite videos, and I've probably watched this atleast 4 times already? <3

Love this channel. Seriously, the visuals are good. The voice over is easy to listen to, and I also like having the subtitles on the screen. However, that music is extremely distracting. Maybe lowering it or putting on a different track such as a gamma wave binaural beat, something that helps the viewer stay focused. Other than that, i love this channel, keep up the fantastic work. :)

very good videos. thank you for your effort.

Don't be shy Eugene, and go further. Please try to make a video explaining how the decoherence on quantum level occurs. Something about quantum vacuum fluctuations would be great as well. I'm sure you understand it pretty well. Definitely one of the best explainers here on youtube. Everything is so clear. Just a pure scientific essence of our reality.

Eugene your videos are eye opening and leave the mind thinking about the subject for days...Thanks for educating so many people with such wonderful illustrations and easy to understand language and analogies.

[bartkwezelstaart]

Great video once more. You're always able to take out the essence but still be quitte educational (at least, for me as a high school student ^^ ). Awesome visualisation!

[rthorarensen]

Best video I have seen explaining the shape and size of the Universe.

[joeyjojojnr]

please keep making more videos!! I am really enjoying them :D i like how sometimes you pause which lets me think about what you have said and visualise it.

[scottgastauerjr]

I love the reaction at 2:08 🤣 detail deserves a sub 🤙🏼

So the theory of a closed universe, the only way that could be possible is if you were to travel in a slight angle, like going around the world. it feels like you are going straight, when in the reality you are actually going in a slight curve, meaning that you would eventually return to the same area you started. but then again if the universe is like a planet (a sphere) what would be outside of that sphere?

Thanks for your effort..
I like the music, the animation and also the accompanying text
