dont you think its weird when you lye down and look at the sky. You stare. All you see is sky or stars (if its night). Where does it end. It HAS to end somewhere... eventually it has too. It cant keep going, what do you think is at the end? But then whats behind that? ITS SO MIND BOGGLING!!! Does anyone else feel disorientated when you think about this kinda stuff?

Yes , I know what you mean, it's really hard to imagine where it end's, but I agree everything has an ending including the sky !! :)

The common accepted value is that OUR "planet/sky" ends about 100km above sea level. That is for our poor little planet.
Above (or after that), it is "Space".
The space (or more precisely the "Universe") has NO end (no boundaries). To visualise this with our poor perceptions of a curved universe, imagine a balloon. This is the Universe.
Mark dots on the balloon: these are stars, planets or galaxies.
The hard thing to conceive is that we are only THE SURFACE OF THE BALLOON, and there is NOTHING INSIDE.
So, as you move around the balloon, you will never reach an end. There are no "ends" on the surface of a sphere...
Once you understand that, the mysteries disappear...
(In reality, it is a bit more complex than that)

It doesn't (to human perception). Having said that, if you went off in a straight line and carried on, you would eventually end up back where you started. The general current scientific consensus is that the universe is a "hypersphere" - a sphere in 4 dimensions. Humans do not have the mental capacity to visualise this 4th dimension: It's easier to consider this if you take a step back to 2D - imagine you are an ant, who can only move forward/back and left/right. If you got to a wall you just carry straight on and walk up the wall, but have no sense that you are actually now going up instead (it's still forward from your perspective). Transpose that to 3D and that's kind of how a 4D hypersphere would work.... carry on long enough and you end up back where you started (and with no idea how you got there!)

“It HAS to end somewhere... eventually it has too”
Those are the words of a person who is closed minded and doesn’t accept new discoveries.
The Cosmos is much WEIRDER than we can even imagine. We have just started to see how crazy everything is once you leave our little home planet and start looking at what really is out there.
Our perspective of “reality” is based on our own world. Once you get something different, you start thinking is not possible or that there has to be a better explanation, or like in your case, you even put on capital letters “HAS” as it is mandatory to end somewhere.
Most people need to wake up from that dream they live into if they want to figure out what our world really is.
And no, to me, there is nothing “disorienting” about this “stuff”. I do not understand most things… yet, but I am open minded and like to investigate, formulate new theories, listen to other people’s theories, and always look forward to find something unexpected and crazy.
Whoever doesn’t feel this way is better to choose something different as career and/or hobby.

so if the sky/space has an ending, what comes after the ending?
you can make up any story you like, it could all be true, we could be living in a test tube in a science lab, we could be in a leather bag held by god, but the next question will always be, so whats ouside the test tube/ whats outside the leather bag, there is no answer, maybe when you die you find out, maybe you dont!

Sky ends nowhere! there is no limit of space, space is unlimited so there is no limit of number of planets. Billions of galaxies are running away from one another into the outer space, space is expanding. But expansion needs more space so where the space is expanding. Solution of this mind boggling phenomena is beyond our human imagination, space is expanding for ever into limitless void !!

Lewis Black knows the answer to this.
It ends on Broadway & 17th in Cincinatti, Ohio. If you walk down the street there - on the left side, is a Starbucks. And... on the right side is the *very same* Starbucks!

YES! It's one of my favourite things to ponder when I am bored at work...and yes, I am also of the opinion that it has to end somewhere, it can't go on forever, nothing can!
