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.
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.
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.
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.
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 light years side to side. It bulges in the middle sixteen thousand light years thick but out by us it's just three thousand light years wide. We're thirty thousand light 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.
And to add the cherry on top, should you ever reach his arbitrary speed limit, it distorts time itself. Even if you flew through space at c for a little weekend getaway, you'd return to a now foreign world only to find time had skipped forward +2,000 years, your entire family and social circles long dead from old age with societal and technical advancements beyond what you could have ever thought possible, completely isolating you. You're now doomed to live in an unfamiliar world where not a single human speaks your language nor can they relate to you in any meaning way.
AKA, gods speeding ticket.
We don't know how big is the universe beyond the observable universe.
99% of the universe is nothing. Wouldn't that really be the dick move?
99% of the universe is nothing.
Worst video game developer ever.
It's actually just our solar system, the rest is just rendering tricks making us think there's distance
Clearly it was made by Bethesda.
The universe is basically 100% empty. An atom is more than 99.9999999 empty space.
Say that again when a brick made of 99,9999999% empty space hits you!
(Mustn't be a hard hit, maybe more like a soft touch. For science, you know.)
Ladies and gentlemen of this supposed jury, is it really fair to say my client hit him, when the brick is essentially 100% empty space? And isn't he also essentially 100% empty space so can he even be hit?
But, ladies and gentlemen of this supposed jury, I have one final thing I want you to consider. Ladies and gentlemen, this is Chewbacca. Chewbacca is a wookie from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about that; that does not make sense! Why would a wookie, an 8 foot tall wookie, want to live on Endor, with a bunch of two foot tall ewoks? That does not make sense!
But more importantly, you have to ask yourself, ‘what does that have to do with this case?’ Nothing. Ladies and Gentlemen, it has nothing to do with this case. It does not make sense! Look at me. I’m a lawyer defending a major record company, and I’m talkin’ about Chewbacca! Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you’re in that jury room deliberatin’ and conjugatin’ the Emancipation Proclamation, does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.
Yeah, I rounded down.
Broad as an ocean, deep as a puddle. Oh great, more rock.
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.
everyone is too stupid to participate
if they are anything like us, its probably for the best.
I don't know, man, I kinda want to hear some of this Vogon poetry I've been hearing so much about.
And sending a space ship at 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 climbing up the Kardashev scale before we're anywhere close to that kind of travel.
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 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.
Also, due to length contraction, at light speed the universe isn’t 96 billion light years wide, it’s 0 anything wide.
At light speed there is no time and no distance, the origin is the destination. You won’t even experience a single tick of Planck time to get there. Instantaneous.
There is no evidence that the Universe is bounded at all. For all we know, it is infinite in spacial dimension.
Wait, now that I think about it, the observable universe have precisely that length because the speed of light, doesn't it?
Its a combination of the speed of light and how inflation has varied the size of the universe. Light's only been able to travel about 14 billion light years since the universe began but those further regions used to be closer so light from them was already part of the way here when they vanished over the cosmic horizon.
Do you believe that the wide expanses of our planet Earth were crafted for the common ant to explore?
When the game is open world but no fast travel or mounts.
Its probably for the best.
If humans are able to get to another planet with life on it we would probably do horrific unspeakable things to the aliens.
Don't forget the part where it's constantly expanding. So it's 96B ly so far.
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.
Dark Forest Theory is probably wrong. In-universe, the series unknowingly undermines it with communication tech that can transmit instantaneously. That would take away the assumption that civilizations can't effectively communicate over interstellar distances and build trust.
In reality, it's something of an extension of the "every individual for themselves" mindset of evolution--something White Supremacists have loved. Kin Selection Theory does away with that. There is a basis for building trust and working together within evolution. The precursor ideas were even done in Peter Kropotkin's "Mutual Aid: A Factor of Evolution" over a century ago. Kin Selection Theory put a mathematical foundation on it.
I like the book series as literature, and the Netflix series has been OK so far (not great, but OK). Liu Cixin himself, however, has some really shitty opinions that come through the text.
I wouldn't worry too much about it. Anything capable of altering fundamental physical parameters like that will be unknowable to us. We'd be like bacteria are to a human.
