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.

This is God creation.
We never know this.
So…. i don't get it then ….. Grrr…. this is so confusing, so how can we date the age of the " whole " universe at 13.8 billion years old then ? I mean ….. if our observable universe is just a tiny percentage of the whole universe then wouldn't it by default have to be much much older then ?
Beyond the Observable Universe is also a Ronnameter which is 1000 Yottameters
The univers was there before human life , people started to give mames to
What they saw and create laws…
The Size of The Universe Is 160,000,000,000 ly and Not Infinite
I think humans are not that thing that can explore whole universe we are like a ant who has to travel whole earth. We must need to make ourselves something else to explore such things
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❤
I like it a lot! But it is NOT long enough 🙂 Also I see a problem. Given where we are in your spot from which we see the universe. How far from Earth IS the center of the Universe? Is it not longer than 13 billion light years away? I think so! If so then we don't really know where the center is at all. LOL –> We need disclaimers – all figures and calculations are best guesses and subject to change.
If the observable universe was tge size of the Earth, Earth would take up a 180th of an atom.
What is space expanding inside of?
People who know that infinity is bigger than the universe

Thank you for using my image for this insightful video, I'm glad it's useful!!!
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.
It's said that if the observable Universe is shrunk down to the size of a helium atom, the entire Universe has the size far greater than our observable Universe at THAT scale. And on top of that incomprehensible size, the entire Universe has more dimensions than the 3 dimensions we're familiar with.
The universe is a eye
The universe is expanding or are there multiple universes
Well according to sir Eddington if you were able to travel as fast as light it would take 1200000 years so??
!Not hating!
Can you explain;)
Rajesh Koothrapali…
The universe is actually the diameter light travels times the age of the universe wich is alot
So is the observable universe set at 93m light years forever?
94 billion ly is diameter or radius of observable universe
