"The universe is expanding " into what?

 As we Have discussed in the previous one  That "THE UNIVERSE IS EXPANDING"   

But what is it expanding into?

is there an unknown area of Nothing that the universe is expanding into?

To understand this question, we again need to know what the universe is made up of?

This IMage will make a clear picture of how is the universe expanding

But one more question here is that "What is the universe made up of?"

It is made up of galaxies, celestial  bodies and gasses and  where nothing is present its vacuum,

SO the universe is expanding Means THat  THE GALAXIES AND THE CELESTIAL BODIES ARE MOVING AWAY FROM EACH it is not that the universe is expanding into the unknown!!

so This question is answered now, But you may also come upon one more question

That" why is the universe expanding?"    

This is the question we will be answering in the next blog

till that time 

keep thinking, be curious, and ask the right questions
