By popular Space Fan request, I offer this video to help answer some of your questions regarding the expanding universe. Many of you consistently ask: If the universe is expanding, then what is it expanding into?
This concept is non-trivial to try and explain in a 5 minute YT video, but I do my best. I hope this helps!
Thanks to all of you space fans for watching this channel, it means a lot to me.
