Does the Universe Have an End ?

Introduction

     If you could go to space and go as far as you wanted, would that be the end? What would it be like to keep on going and going? Will it keep going forever? Probably everyone wants to see what and maybe who else is out there.

The Beginning

     At the beginning of the universe there was only time or space. Everything was under an incredibly high pressure and temperature all squished together in one big, hot tight spot.

    Most astronomers use the Big Bang Theory to explain how the universe began. The Big Bang Theory is like a giant explosion that begins the universe. But what caused this explosion in the first place is still unknown.

The Big Bang Theory

     The Big Bang Theory says the universe started with an extremely hot and dense single point which stretched first at unimaginable speeds, and then kept stretching at a more common rate  over the next 13.8 billion years. Based on this theory, the universe is still expanding today. 

     The Big Bang Theory is scientist's explanation for how the universe began. In the beginning , the universe grew from an extremely small point to nearly an octillion (that's a 1 followed by 27 zeros) times that in size in less than a trillionth of a second. WOW!

      Here is the number octillion: 1,000,000,000,000,000,000,000,000,000. That's HUGE!!!!

Size and Age

     Scientists figured the size of the universe depends on its shape and how fast it is getting bigger. Most astronomers think that the universe is about 13.8 billion years old and stretches out for 93 billion light-years... and it is still growing! 

     The universe is at least 250 times larger than the observable universe, so scientists can only make theories about how big it really is.

Answer

     Since the universe just keeps expanding, the universe is infinite. You cannot reach the end because it is always expanding. Going to the "edge of the universe" is something that only exists in fictional movies. You also can’t travel to the end observable universe, which is the part of the universe that we can see.
