What is the size of the universe?(Unsolved Problems in Physics #1 )

Logic Level 2

The universe is always growing more stars, more black holes, and more planets. Scientists say the universe is about 93 billion light-years. Wait so if the universe size is 93 billion light-years doesn't it mean that the universe size will change because it is expanding? So for real, what is the real size of the universe?

100,000 light years Undefined/infinite 4 inches idk 93 billion light-years

We really don't the actual size of the universe. We have just seen a small part of our universe which we call Observable Universe .

Although it is proved that our universe is expanding but we don't know how big is our universe.

There are different theories based on Parallel world , Multiverse . It suggests that their could be infinitely many co-existing universes.

We have just started our journey to the universe. There are infinitely many things to be discovered :):)

Not sure what the purpose of this question is. It's classified as "Logic" but that's clearly not right.

To be exact logic means of or according to the rules of logic or formal argument as an adjective and this is an argument between many scientists. ( Not in the scientific definition)

The purpose of this question - This question's purpose is to show/teach others about science, about what is the exact size of the universe which is undefined or infinite.

It certainly doesn't teach anyone about science. All I see is misinformation. Scientists don't claim that the size of the universe is 93 billion lightyears.

@Krishna Karthik – When i say that the right answer, the right answer is Undefined

@Oofmation Animation – The right answer is that we don't know it at the moment. However, you sought to say that scientists estimated that the universe's size is 93 billion light years.

@Krishna Karthik – I say some think that way I know it is infinite also if you look at my this states: The universe is expanding every second and Scientists say that the universe is* about* 93 billion light-years, so it more clear to say it undefined or infinite, than changing the size every year.

@Oofmation Animation – We don't know what is the size of the universe, although it's expanding, but some where it is decreasing also. I don't think we can classify our universe by our current knowledge. We can put huge information, but we can't know what is real with our current knowledge.

If we consider the theories of Parallel Universe and Multiverse then we will be unable to predict the size. It will be vague.

As a side note, if the answer is undefined/infinite, idk should, at least to some extent, be correct. Not as correct to be justified picking it but still

No scientists claim that the size of the universe is 93 billion lightyears. This is the size of the observable universe.

The actual size of the universe, outside our small cluster, is thought to be much much bigger. We don't know the size of the universe, nor do scientists claim they do. We just know that it is humongous and it is expanding.

Some Scientist say this

The universe is expanding every second and Scientists say that the universe is * about * 93 billion light-years, so it more clear to say it undefined or infinite, than changing the size every year.

you statement implies that we don't know the size. so why do you select "infinite" as correct answer? it sounds like "idk" should be the required answer.
