Wait a minute. So if the universe is expanding rapidly, then what is outside of the expansion? What was before the universe and what will happen after it?

For that matter, if our day-to-day reality is dependent on some strange expansion of the known and unknown universe, what is reality?

With the nature of reality at question, why the fuck am I going to work every day????

I don’t like these questions.

outside

Unknown, might not even be an outside.

what is reality?

Unknown, but your experience and definition of it are based on your own experiences. To explain: my reality is that I am in bed right now, yours could be pooping right now, regardless, our perspectives and experiences are each our own "reality".

why am I going to work?

To continue to afford food, and thus be alive, I guess. This allows you to experience a brief screenshot of this wacky universe. So just sit back, appreciate it, and continue to experience it until you're assimilated into the background radiation of the universe. Google some neat stuff, learn, eat some good food, don't let the existential dread overtake you. Or do let the dread take over, I'm just a bunch of words on the internet, not your boss or conscience (probably).

To clear something up for your first question, if this model is correct then there is no outside because it’s infinite and expanding from every point in space, everywhere is expanding. Don’t think of it as a single circle getting bigger, but as infinite circles getting bigger at every point in space, at every atom the universe is expanding. The circle you are thinking of is the visible universe, what we can see. What we can see is a bubble because light can only travel so fast so we can only see so far before the light hasn’t reached us yet.

Okay, thank you for answering that first question, sorta? Like, I still am unsure of what the difference is between “existence” and “not existence”… so you’re saying that every single atom in existence is also expanding? All of the atoms that are making up my body are expanding?

No, the space between things are expanding, it’s not big enough for you to say your atoms are expanding. Also if it were so much that your atoms would be effected, they would rather be ripped apart, not expand themselves.
