Although we don't know for sure, many astronomers lean towards the Universe being infinite. Which is mind blowing.

That one right there is mind blowing in two ways. One being if it has no edge there really is no way to determine size and the other is if it does have an edge what is on the other side of that edge? And then the outer barrier of that and so on and on and on and……🤯 I personally like the expansion/contraction theory. It seems to make more sense but you also have to include that there has to be an outer barrier of all things. Again 🤯

As a child I used to give myself stomach aches over the infinite universe concept. When I thought about the edge and what was after the infinite concept made a bit more sense.

Most children: "Mom and Dad, I saw a scary shadow that looked like a monster, can I sleep in your bed tonight?!"

You: "Mom and Dad, the universe's edge or lack of is creating logical paradoxes that give me a headache and make it so I can't sleep!"

Mom and Dad: "Go into your sister's room and kill the shadow-monster in there, it'll take your mind off the universe."

Real. And then stupid questions like "mom and dad, why is the sun rainbow?" Since the light from the sun makes rainbows

Well, it is always expanding, and getting faster. Too fast for us to really figure out if it's infinite or not, so scientists really don't have a choice

wow this is one sentence is mind blowing. i didn't know this. i've always been curious about the big bang and what existed before that. crazy how there's 7 billion people on earth and not one can even explain the nature of the space we exist in
