assuming infinity and homogenous distribution, what would you see if you kept zooming out on the observable universe? just white light?

Quick, How are supercluster dimensions of this rationalization approximated?

What theory dictates the apparent distances?

>not enough energy

I've been wondering...
Is it really reasonable to think that humans have all the sensory faculties to detect most objects in the universe, or more fundamentally, to even understand what the universe is?

Scientists so far have indirectly measured that over 95% of the matter and energy in the universe is completely outside of the realm of human knowledge.

For example, some animals do not have vision at all, so their perception of the world is fundamentally different to ours. Perhaps the way we perceive the universe is extremely narrow and not nearly enough to explain it.
Another point, our brains, they were developed over millions of years of evolution and hence are based on traits that proved beneficial for survival. Perhaps our very logic, our way of thinking is contrary to the kind of logic necessary to understand the universe?

There's been something bothering me recently.

How come wherever we look, there seems to be regularity in this Universe? From the smallest of scales to the greatest, virtually everything can be calculated using maths and it stays consistent. From the expansion of the whole universe to the quantum level.

It's as if the universe itself is rational, and as I said before, the values are cunningly consistent and devious with something we Humans made up (mathematics). It's also strange how Maths is the one area of study that is most likely to drive us to madness, despite it's influence on helping us learn about the universe and more.

If we look at the various fundamental constants of the universe, it's ridiculous how "fine tuned" everything is. Why do they have the values they have? If their value was ever so slightly different, we wouldn't be around. Take for example the strong interaction. If it was slightly stronger, stars wouldn't exist or not for very long. If they were slightly weaker, it'd ultimately be too weak to hold together elements including the essential isotope Deuterium. This doesn't apply to just the fundamental constants but many other constants too which govern the laws of the universe to fantastic accuracy.

We're also now advancing far past the sense of our own logic - You only just have to check out the advancements made in quantum mechanics. Really, it doesn't make sense thinking about it logically and that's understandable. We, as Humans, find it difficult to comprehend to that which we can't relate to. But, quantum mechanics and the mathematical formulas behind it is still completely rational which I personally find absolutely amazing. Maths makes sense far above and beyond our own sense of logic.

Is it possible there are other universes in the same universe so to speak, just like there are other galaxies, clusters and so on?

Is the Universe infinite in size? Not talking about the observable universe. Presumably, every point in space has an observable universe of finite size around it. The universe is a finite age, does this entail a finite size? Or does it not make sense to think of there being an "edge" of the universe, where that point would observe nothing in the 180 degrees outwards from the edge. Both of them are hard to visualize, so /sci/ what do you say?

If there is an infinite number of parallel universes, wouldn't there exist a universe where no other parallel universes exist alongside it?

If there is truely an infinite number of universes, does that mean that there is an infinite number of parallel universes that are exactly like this one, but I have a different haircut? And another set of infinite universes where all that's different is I had 3 eggs for breakfast instead of 2?
When people say infinite parallel universes, do they literally mean infinite? Or is it just so many that they can't count?

Also I like tyr, cos kinase!!!

What is the size of the universe?
(not to be confused with the observable universe that is approx 13.75 ± 0.11, I expect the universe is much bigger?)

So, what's /sci/'s opinion on the size of the universe? Infinite or finite?

The metaverse.

So why did the universe begin ( how did The Big Bang occur)? What is the universe expanding into? Why does learning about cosmology make you tear up knowing you'll never know exactly why we're all here?

How are pictures like this produced?

the universe is infinite in the same way a world in a video game is infinite; an object in a video game can travel as far as it wants as long as the computer running the game can physically handle computing the distance.

taking this into account, the universe will keep expanding until it reaches the maximum size that the "universe" can handle, at which point it will either stop expanding or the "universe" will crash and everything will stop existing.

We've observed the large-scale structure of the universe. There seems to be a pattern. It's uniform throughout the observable universe. Galaxies are in large clusters that form a kind of web shape.

The universe is infinite. It never ends.

Some food for you (no troll).

Everybody agrees that the speed of light is a constant, that nothing can travel faster than it.

So, for example we have a wormhole that has it's holes situated longer than the length of 10 seconds that light could travel.

I would step into the wormhole and emerge from the other end after 5 seconds (or even 9,9999999999999 seconds if you wish).

There are only four conclusions that I could draw from that thought process:

Either
a)The speed of light is not the speed limit of a particle or body
b)Wormholes don't exist because of the speed of light being the speed limit
c)Time changes in favor to me
d)Time changes in favor to the universe

nt isprime(int num)
{
int test;
int index;
for(index =2 ; index <= sqrt(num); index++)
{

test = num%index;
if(test== 0)
{
return 0;//returns nothing if not a prime
}
}


return num;//returns prime


}


//This is too slow, think it can be improved?
aside from being better commented and neater

Is the universe a big cell??
