Observable Universe VS Actual Universe
ฝัง
- เผยแพร่เมื่อ 17 เม.ย. 2023
- The observable universe refers to the portion of the universe that we can observe from our position on Earth, or through our telescopes and other scientific instruments. This includes everything that can be seen by electromagnetic radiation such as light, radio waves, X-rays, and so on.
On the other hand, the actual universe refers to the entire universe, which includes everything that exists, both seen and unseen. The actual universe is much larger than the observable universe, and it is believed to extend beyond the limit of what we can see, even with our most advanced instruments.
The reason for this is that light travels at a finite speed, and the universe is thought to have a finite age. This means that light emitted from objects located beyond a certain distance from us has not had enough time to reach us yet. This boundary is called the "light horizon" and it marks the limit of the observable universe.
The actual universe may be much larger than the observable universe, and it may contain structures and objects that we can never see or detect. This is because they may be located beyond the light horizon or because they may be made up of particles or other matter that does not interact with light or other forms of radiation that we can detect.

I wonder if 30 BillTrill is more or less than a Google.. or Googleplex
@@rabbitfari it's still less than a googol
@@rabbitfari its quintillion bruh
@@rabbitfari it's an extremely small number if you want to play with the big ones.
30BillTrill is about 3*10^22. one googol is 10^100.
the cube of 30BillTrill is still smaller than a googol.
according to the wikipedia, it is suggested, but not yet verified, that the game of go has a game-tree complexity of 10^360. more than the cube of a googol.
a googolplex is, still, absurdly larger than that.
and a googolplexplex is so large that it's not even worth to try to understand the idea.
just to make it clear, if a person writes 2 digits per second it would take more than the cube of 30BillTrill seconds to write the entire googolplex.
30 billion trillion may sound "a big number" but it's too small to be considered small.

Thats a rough estimate on their number and likely completely wrong. There is a massive amount of stuff we cant even see. So that estimation was completely and utterly pointless.

Congratulation 🎉 in advance🎉🎉🎉
Thank you so much ❤️
Fuck it man, we will never know
The unknowable unknowns are immeasurable by definition 😮
If the first part is a part of the second part, it's just one part altogether. It is one universe.
Exactly. They mount separate it bc the area behind what we can observe will never be observable by us, so in reality we have no scientific proof of what is behind it. Common sense tells us it’s the same as what we can see but science is still science, so gotta have evidence
Where are we , for all we know our UNIVERSE could be an atom flying in an atom smasher while a scientist watches !

@@time43200sextillion according to the theory of inflation, and 150SX it could be higher or even infinite though
@@craigdavies2598 The definition of infinity is that even if you break infinity into INFINITE parts still the remaining will always be infinite so why does the expansion rate of Universe is 72 km/sec per Megaparsec in our local region it should also be infinite, our own region should also be expanding with infinite velocity and there shouldn't be any other galaxy around us other then our own milky way galaxy the reason is that universe is finite but that number is very big for example our observable universe is 93 Billion light years but the true extent of universe is inevitably big but not infinite so according to this equation D=H°×(T)^2 Universe is finite. Where H°= 72 km/sec/Mpc of expansion rate and T= age of universe in seconds and the resultant is the diameter of universe that is 1.337×10^37 km or 1.413×10^24 Light years or 15 Trillion times bigger then the current size of observable universe

The real question is has the light beyond 13 billion light years not reached us yet, or has gravity stretched the light beyond what we can detect and measure.
Space seems to be expanding apart at any given point. No matter where you are. Everything far away is moving away. Get far enough out, space itself is expanding faster than the speed of light relative to us. The expansion is exponential the further out we measure.
Idk if it's true or not lol. Just what I've been thinking
@@Breakstuff5050 technically it's red shifted and the further you see the more redshift you measure, doesn't mean expansion, let me give you a hypothetical;
You have a corridor of galaxies and a stream of golf balls or even just 2 moving at the speed of light, the dots are galaxies...
🏌️♂️⚽➡️::::::::::::::::::::::::::::::
So the golf balls travel 100m apart through the centre, does the distance between the golf balls increase through the journey?
Damn bro, how’d you managed to fit the whole universe into an imagine on my phone??? Pretty crazy my guy.
93 billion light years diameter so it's overall 27 trillion 157 billion and 634 million light years territory. (2.91²² km)
They now know that under variable circumstances, light changes speed, can bend, curve, break, and even freeze.
Crazier still is ... What if we are near the right side of the universe or the left side or near the top or the bottom.. how much universe will there be? Keep in mind .. if our earth is a sphere we can observe the universe from every side of the earth therefore being totally engulfed by universe like being immersed in water. It's so totally unfathomable and amazing. Now imagine how unfathomably awesome God is who created all of this.

Hypothetically, there are about one quinvigintillion to ten sesvigintillion atoms in the observable universe. A quinvigintillion is 1 followed by 78 zeroes and one sesvigintillion is 1 followed by 81 zeroes.
I just cant believe light is that slow
The universe isn't divided into two parts just because we can't see all of it. We don't know if it's infinite or finite expanding into a void, and there are important differences between these possibilities. However, the universe, whether finite or infinite, is a single, cohesive entity.
What if the actual universe is the MULTIVERSE and the observable universe is just a tiny dot in it

Only one explanation for the universe, it is infinite as far as we are concerned.
It looks like an eye what if that's the eye of a very big creature😮
It’s not an actual picture of the universe
The actual universe is smaller than the observable universe, because I said so, ..
it's funny how in every illustration of the observable universe our sun and solar system is at the dead center. might as well keep thinking that our Earth 🌎 is the center of our solar system, too.
It’s a logarithmic representation of the universe not the actual one. Just for reference
Imagine our universe is incomprehensible to our small minds. We only know what it allows us to know as we are programmed.
Maybe the universe is a sphere like an atom that is part of something insanely bigger.. we are here just to be an observer and record information while we live out our small existence.
While we sit here and think it's all about us and all for us. Probably farthest from the truth. Little primitive minds think so highly of ourselves. While we destroy the earth like a virus spreading and consuming until it's gone.
One theory I saw was that we are a product of the universe trying to understand itself

If the universe is infinite, that actually causes alot of wacky scenarios to occur.
For example, if it is infinite, that means that there are an infinite number of you reading this comment in the exact same position you are sitting/standing/whatever right now at this very second.
Nice wacky idea but also I don't think that'll happen since the duplicate would need to have everything identical leading to you, your parents, their parents, with the same orientation of stars and galaxies, the same perspective in the cosmic microwave background with regions of slightly lower and higher temperature fluctuations, etc... and then there's quantum uncertainty and that an electron can be in an infinite range of places. Still, maybe an infinite universe could duplicate all of that at least for a moment until the quantum randomness causes a split. (odds are virtually 100% of splitting to a difference the next nanosecond)
Another wacky effect though is that we'd be far more likely to find many alternate histories of Earth instead of exact replica, because there are so many more possibilities of them, vs only one possibility in achieving an identical replica.
@@localverse But in an infinite universe, if it happens once....it can happen again an infinite number of times.
There is no end to the universe. Travel far enough, and you will run into yourself that just so happened to go in the opposite direction.
The complications are so whacky that it's too hard to believe. Which is why I don't believe in it. The universe simply does not deal in infinites.
@@Electru522 hmm interesting 🤔 well if your duplicate does go in the opposite direction, everything in the cosmos would have to match for billions of light years for each of both of you, so odds are you'd have to pass by countless almost exact replicas of your neck of the cosmos that are alternate histories where things went differently, and on the way to those almost replicas you'd have to pass vastly more totally different alternate histories, like where Theia hadn't crashed into Earth to form the moon, or where dinosaurs hadn't gone extinct, or even where Earth had drifted beyond the habitable zone... because the variations are a lot more common than the exact match, due to probabilities.
@@localverse Correct. And each one of those variations also happens an infinite number of times. It's pretty much a roundabout way of creating a multiverse.
In an infinite universe, if something can happen that is within the laws of science, it happened.....and it happened an infinite number of times.
Atom vs the size of the observable universe. The observable universe is the true universe in this example, and the atom would be our observable universe. This portion is tiny.

We are nothing. We need to stay humble all the time. And be thankful for existing in a time where we can see how beautiful our universe is.

We live in a little marble like on MIB
Wow !!!
Until I saw this picture… I never realized how big the earth really was 😂
It’s not an actual depiction of the scale of the universe.
And we will never ever know.
I think that not so long ago, the mass of the entire universe has been estimated based on the observed curvature of space compared with the observed estimated mass of the observable universe. It results in a total figure for the mass of about 15 million times the mass of the observable universe. That would seem to be a good starting point for estimating the size of the actual universe.
all we need is to invent the hyper-space jump :D
I there are also other species in the universe and they also don't want to accept that there are also other species in the universe like us
They may know our existence
There should be 3 parts. The observable, the constant expansion, and the actual of where the universe is expanding into.
Seems to me that it kind of renders as it's observed .ie waves turning into particles on observation (double slit experiment). So whatever you view is rendered as you view it to save data, just like a video game, so it can be seemingly infinite but it only needs to render what is being observed.
we can actually "see" and count star in observable universe. just like measuring how much water in the sea. just count how many star we can actually see and average-in them to the entire universe. the larger the sample, more accurate it is
The observable universe could just be one of a trillion more universes that orbit a galaxy of universes, and then a supercluster of universe galaxies
Who knows there could be any bigger after the universe of universes?
And I feel overwhelmed with Starfield's over 1500 planets. I'm glad they didn't decide to go for ultra realism and had this much to put into the game. So theoretically, wouldn't this also mean there is a large portion of the universe that's unexplored in Starfield as well? That's some cool ass shit 😅
Mesmerizing thoughts
What we studied: Solar system
Exam:
I'M NOT CONFUSED WITH BIG THINGS LIKE OMNIVERSE AND MULTIVERSE
motion will not stop. nor may it begin. you may not reach absolute zero or light speed. big bang is the idea that all potential begins close to stillness so this universe is as infinite as is miniscule the chance of finding a grain of sand with mass / potential of all observations / actions conceivable.
I've had this thought following me since I was about 7 years old I'm 32 now and I still get lost in my thoughts about how far the universe actually goes. 30 billion trillion woowww '*flavor flav v*'! This is pure nostalgia for me❤
The universe is expanding out faster then we could even build a telescope to see beyond the observable universe. Also the length of observable universe doesn't change but what we see in it does or the lack there of as it's expanding, galaxies are leaving the observable universe
Constant speed?
Actually...
Our universe looks like an eyeball
it's funny that almost every picture I've seen of what the observable universe looks like, it looks like an eyeball
Correction...we can only guess at the actual size of the universe based on detection of background radiation.
How do we even know all this like HOW
Science
True answer: We don’t, at all. We just estimated that there was a bigger Universe after collecting evidence from the “Observable Universe”. through our deep understanding of other galaxies existing upon us, we started just Creating the fact that there is a HUGE universe upon the “Observable Universe”. (I could be wrong, but this is just my research from multiple sources)
Seems we are irrelevant in the grand scheme of things
Pretty much, it seems in most TH-cam comments there is always an argument. I wish I knew why were so bent on being right, all the time. I'm human and it's ok to be wrong and make mistakes. 😊
@RobertSimpson-wp3pr you don't have a choice - you will be wrong at times - so might as well embrace it

I'm quite curious how do we know that there is something beyond the observable universe this might be a dumb question but still am curious
We don't. But we can interpolate.
Speed of light: 186,000 miles per second. Quantum mechanics defies the speed of light. It's a special non-classical law of physics.
Praise god for your wonderful creation 💕
This is why I hate people talking about the Big Bang singularity as the infinitesimal starting point of the universe! No, it's just the point where all the timelines in our observable chunk fall back. There's no telling how big it was then, and if the universe is infinite, then it was infinite then, too.
There isn't a discernable curve, so it probably isn't doughnut shaped, but if it were you could fly until you end up in the same spot, eventually. Maybe there are a bunch of doughnuts.
