Is ''space'' really the only thing that exists?

Sometimes when I think about this, this galaxy, the hundreds of sextillion miles of space, I wonder if there is anything else. Not God, Heaven, Satan or Hell, but.. Just something else. About 13 billion years ago dark matter collided with normal matter, resulting in what is known as the big bang. The universe started and has been expanding ever since. But what was before that? What is space expanding into? Like.. This drawing.



Black is space. The arrows indicate that it's expanding. The white area.. What's there?

Recently I've heard of the term ''heat death'', which describes how the universe will eventually die.. Is that the end of everything that exists and will ever exist? Or is it the beginning of something new?

Share your thoughts, please.

 

I suppose the white area is just void, the same as space that contains no matter?

As for heat death, that doesn't mean that everything in the universe ceases to exist, it just means that essentially no more usable energy will be around, which will take much much longer than our planet's lifetime to happen.

 

We still don't know about that, isn't scientists finding answers to that?
When that day comes when all the truths are revealed, I can't wait to see what all the religious people would say to defend themselves.

 

Ignore and denie it like they did with Galileo. Maybe.

 

I would like to add on that scientists found an area in space with absolutely nothing but darkness. Like no stars meteors or any other object.
Also What if there is different levels to space like inhabitable layer (like in a apartment) and say we go too low (basement) in space then that is not habitable. Say we go too high (roof) that area is not habitable. So what is there is a middle region which is habitable? and we are in this region or "Layer" of space?

 

I think they proved the universe is flat. There's no basement or roof. I may be wrong, ofcourse.

 

the space is not flat. there is no definite bottom or top but im saying in generalized massive regions of the space.

 

I suppose I can try to answer one of your questions. This is the best my intuition can do.

Space is incessantly expanding at an accelerated rate. It's currently thought to be impossible to reach its edges. Therefore, space has no boundaries so far as we are concerned. This leads me to believe there isn't void outside it.

 

Actually I think he's correct, I remember reading somewhere that space is indeed flat

 

Actually it isn't accelerating time is just slowing down giving the appearance of acceleration this is known as time dilation.

But yes there is no boundary outside it nor is there anything outside of it until light has reached this there is nothing not even blank space.


Note : below is theory not fact

The universe will not end in heat death when the universe starts slowing it will not slow to a near halt it will start in reverse and start collapsing in on itself and when the black holes start combining they will combine and become so massive the entire universe will be compressed into a singularity once again and then a new big bang will happen.

 

No one's really certain how the universe began, so I'm not sure where you heard that dark matter collided with normal matter.

But since you asked about what space is expanding into, I'd like to give you a very nice analogy I heard Alan Watts use:


Some 13 billion years ago there was a first instance of creation; God, the Big Bang, whatever you want to call it. Now, a good way to picture what this is is to imagine throwing an ink bottle against a wall. In the center there is nothing but a large, amorphous blob, but as you move away from it and approach the edges, you'll find that the patterns become more varied and complex.

Well, that's us. We are the the tiny, yet complicated, creatures who are the end results of the ongoing processes set in motion at that first instance of creation.




Try not to visualize the universe in such a black and white manner. More specifically, don't think of it as a big balloon with all the stars and galaxies inside of it and some unknown realm outside of it. It's very easy to run into walls when you try and apply the reality you're accustomed to perceiving while trying to conceive the totality of everything that exists.

 

Actually time is slowing down not universe expanding faster time dilation makes it appear faster yet that doesn't solve the problem you brought up. But the fact its expanding out should mean it started out in one location.

That is true it is not testable but that does not mean its false.

I was always wondering why people say a god cannot exist because there is no proof yet assume their theories even when there is contradicting evidence.

I am a Deist not very religious but it always angered me.

I lean towards the Cyclic universe Theory on this I believe there is no beginning or end the universe will keep repeating over and over it just always ever was. I would love your critique on my thread I wrote about it.

Poorly written by an average young American with little understanding of the world with just curiosity as motivation.

 

God created the universe - end of story

 

Lol'd.

Yes all mighty one!

 

It's confusing.

 

Time dilation makes things appear to be moving different speeds then they are but its really just the perception of time slowing down.

Cant answer the other 2
