Don't forget the part where it's constantly expanding. So it's 96B ly so far.

A faster light speed wouldn't make a difference, since she made the universe 96 billion light years wide.
Something tells me this isn't a bad thing. If there is an edge of the universe, it's probably going to be a very strange place.
And Earth is already stranger than some would like.
And that is scary. If the is one takeaway from observing the universe it's that there are always bigger and stranger things out there somewhere.
Indeed, but the way the math for expansion works is that there is something called a Hubble horizon and that makes it impossible to ever reach the edge, since it is moving away from us faster than light. (The limit doesn't apply to the expansion of space-time).
Quite a nifty solution by the Supreme Programmer to avoid us hitting the limits of the simulation. I couldn't have designed it better.
I couldn’t have designed it better.
Delta Force game programmers: Ghm, that was a trivial solution to the problem.
Well it was a more convincing solution than just having level crossing arms come down and an infinitely long train cross every time you get near the edge.

Good thing there isn't one since we probably live in a donut.
I thought it was technically a three-dimensional donut shape progressing along a sort of 4D taurus that we only exist on the "surface" of?
It's actually turtles all the way down.
Ah shit 🤯
That's a common misconception. We actually live on the surface of a 3D bear claw progressing along a 4D cruller.

Imagine there being just no stars behind you. Just nothing. On one side you see the universe, like a wall of stars and lights, and next to that just pure nothingness. The void.
Or the quantum foam, or both, it'd be wild to be able to stare out into that sorta of black, in a metal way.
A bit off-topic but the voids in the universe (such as Bootes void) are scary af.
You could never get to the void because space-time has already accelerated the edge of all matter away from you faster than the speed of light.
Not "the void," no, but "a void," yes. As the universe continues to expand faster than the speed of light, the stars outside of our galaxy will slowly disappear from view. There will come a time when the night sky is just the milky way and darkness elsewhere. I don't know if anything will still be around to observe it, though.

Tell me all your thoughts on God 'cause I would really like to meet her
Disclaimer: To any higher power listening, I am not done living and do not want to meet God/a god immediately. There's still plenty of candy left in this piñata.

You can't do this to me. I started this company. You know how much I sacrificed?!

Light speed is a "you must be this clever to participate" barrier to becoming an interstellar species, that's all. Even if it's not breakable, it just means you gotta be able to plan hundreds or thousands of years into the future.
We can hardly plan 5 years into the future, let alone hundreds of thousands... It'd be pretty sad if the answer to the Fermi paradox is that everyone is too stupid to participate.
It's not "just" the speed of light though, light is limited by the speed of information, also known as the speed of causality. If you were to somehow exceed that, then your future light cone becomes very messed up, and effect starts to be possible before cause.

I mean, have you seen the human back, fuckin psychopath LMAO
Just remember that you're standing on a planet that's evolving and revolving at nine hundred miles an hour, that's orbiting at nineteen miles a second, so it's reckoned a sun that is the source of all our power. The sun, and you and me, and all the stars that we can see are moving at a million miles a day. In an outer spiral arm, at forty thousand miles an hour, of the galaxy we call the Milky Way.
Our galaxy itself contains a hundred billion stars. It's a hundred thousand lights years side to side. It bulges in the middle sixteen thousand lights years thick but out by us it's just three thousand lights years wide. We're thirty thousand lights years from galactic central point, we go around every two hundred million years and our galaxy is only one of millions of billions in this amazing and expanding universe.
The universe itself keeps on expanding and expanding, in all of the directions it can whiz. As fast as it can go, at the speed of light, you know, twelve million miles a minute and that's the fastest speed thereis. So remember when you're feeling very small and insecure, how amazingly unlikely is your birth and pray that there's intelligent life somewhere up in space because there's bugger all down here on earth.
When the game is open world but no fast travel or mounts.
The universe is actually expanding at a rate faster than the speed of light. There's only a finite distance we'd technically be able to travel if we were to leave right now.

This is assuming that the universe is for us. It's probably not for anything, but to the extent that it is for a kind of life, it might not be us.
And sending a space ship at at least a good fraction of light speed to a nearby star uses more energy than our total civilization uses at the moment. We've got some work to do before climbing up the Kardashev scale we're anywhere close to that kind of travel.

"God" doesn't exist in science.
It's just a meme, bro
"God" in this meme just refers to "the reason lightspeed is c and not something else". Quit inserting agendas and just enjoy the meme
No, I don't think I will.

Hear me out. It doesn't even matter that it's 96 billion light-years away if you're traveling at light speed. Because if you can travel at light speed, time would be better Frozen for you relative to earth time.
So if you're in a spaceship traveling at light speed to your destination, it would feel like you gotten there in an instant.
In an instant from the point of view of the people on Earth, but from your point of view time still moves forward.
Other way around. Instant from your POV but not from Earth's.
Not the other way? You'd feel like you got there in an instant, while people on Earth needed to wait years?
Time is frozen at light speed. You arrive at your destination instantaneously, not even experiencing a tick of Planck time. To an outside observer it takes you time. From the perspective of a photon from the sun, there is no time or distance passing between its genesis in the sun and it landing on your face. From an observer on earth it took 8 minutes and millions of miles.

We don't know how big is the universe beyond the observable universe.

Nah, we can bend space. Sam Neill checkmates God.
There is idea in the three body problem novels:
Tap for spoiler
That the speed of light was infinity at the birth of the universe but sentient species reduced the speed of light several times as a offence/defense mechanism to protect themselves from others.
The mere though of that is dreadful to me.

There is no evidence that the Universe is bounded at all. For all we know, it is infinite in spacial dimension.
