The infinite space of the Universe

quote:

---

Space, iself, is expanding... not the matter within space.

​

And it doesn't expand through something and it isn't expanding into something.

​

The universe has a four deminsional shape that is an expansion in 3d. That's all

This is another gross over-simplification. In the material world that we happen to live in, EVERYTHING is contained into something else(bigger).We don't know if space is expanding(so far we know about matter expanding), let alone what space is expanding into or if the whole universe is self-contained(as you claim, which seems like an over-simplification).Edited by Agobot, : No reason given.Edited by Agobot, : No reason given.

To answer a stupid question: "What makes you think there is gravity in the empty space of the universe[?]"
Well, as the force goes on into infinity, by definition, the force exerted by gravity permeates the entire universe.

---

OMG. Now you are saying gravity generated by the Sun will go on into infinity? Are you really saying this??? Do you know what escape velocity means? Or being weightless? Or you didn't get the key part - I was talking of empty space 90 billion light years away from us.Edited by Agobot, : No reason given.

Uhh, no... you're just wrong here. Space is what is expanding, not matter. You need to read up on the subject. Take a look here.

The universe, by definition, is everything. There is nothing "outside" of the universe so it has to be self-contained. And there isn't anything for it to expand into, because if there was, then that would be a part of the universe too.

The thing that sucks is that there are lot of intellegent and friendly people that you could have learned a lot about cosmology from had you not had such a shitty attitude.

The last thing I had in mind making this thread was turning the thread into a knowall wanna-be's playground. The topic is very far from our current state of knowledge and the last thing i was expecting was clear "answers". The aim was to collect some hypotesis about what's out there where the material universe ends and see what others are thinking on the matter. Then, at the end of the thread, it was turned into a religeous discussion where no facts were supplied, just bare claims and faith.

I think we shouln't be looking for purpose and logic in the universe at all costs. Colossal events like the Big Bang, the emergence and existence of life, the size of the universe, etc, don't make sense. So why should the universe as a whole make any sense?
I think I am with Einstein on this... "the universe is not stranger than we imagine, it's stranger than WE CAN imagine".

At a back hole, the mass is so large that even light cannot escape. The mass of the big bang would be far far superior to that of a black hole. How then could the mass be expelled? Wouldn't the gravitational field be so massive there's no way the universe could expand from it?

Our laws of physics don't work in such scenarios. Good luck finding the answer.PS. Has any research confirmed the long held belief that black holes can actually explode at some point of their life?Edited by Agobot, : No reason given.Edited by Agobot, : No reason given.Edited by Agobot, : No reason given.

Space is matter?
How so?

If space is not matter, then space does not exist. If we assume that space is not matter and it exists, then it would make sense that space could very well be infinite(since it's not matter). Empty space, devoid of matter and particles is a mind-boggling concept though.Edited by Agobot, : No reason given.Edited by Agobot, : No reason given.

If space existed the way time "exists", you'd be living in a very virtual world.

Here is something worthwhile - Time is a concept while space has a very material existence. You need proof?Dictionary.com | Meanings and Definitions of Words at Dictionary.comEdited by Agobot, : No reason given.Edited by Agobot, : No reason given.

Anyone who can read a dictionary, a book or a the internet can see that the existence of time is immaterial. Another example of immaterial existence is our imagination. I was saying that if space is completly void of matter and particles, then it cannot exist(unless you want to say that space is just an idea). But drawing comparisons between the physical existence of time and space is utter nonsense, as is bringing in the general relativity theory into the debate.

quote:

---

General Relativity is quite important when discussing the reality of time. According to General Relativity time can be physically bent by mass. Also this is a confirmed prediction of General Relativity.
Hence we have evidence that time is a physically real thing. I know of very few man made concepts that can be bent in a physically real sense.

Space-time is not the same as time. Space-time is our 3D universe plus time as the 4th dimension. While time is, well, look at your wrist watch. Edited by Agobot, : No reason given.

There has been a lot of misunderstanding, miscommunication and topic drift in this thread because of hard to grasp notions. One of them is space. Let's see what your hypothesis is about it? What exactly is empty space if it's completely void of matter and particles? Nothingness? Something non-material that has no measurable or observable qualities, yet its existence is non-disputed and unquestioned by us? Our lives are very much meaningless in the grand scheme of things - the scales of the universe don't suggest we play more than a trillionth of a percent role for anything out there, so it's quite possible that we might never manage to get the answers we want.

It may change shape and form but it will never end.

Now this is a religious answer.

Have you ever sensed the presence of god? Where and how? All i have felt in my entire life was complete lack of devine guidance and purely random events and occurences everywhere on earth. Which event in earth's history would you label as god's act/bible aside/? Show me one, just one. Edited by Agobot, : No reason given.

Catholic Scientist, have you even looked at the links you provided? I am sure you have not, as straight from the links you can see:"An issue of philosophical debate is whether space is an ontological entity itself, or simply a conceptual framework humans need to think (and talk) about the world. Another way to frame this is to ask, "Can space itself be measured, or is space part of the measurement system?" The same debate applies also to time, and an important formulation in both areas was given by Immanuel Kant."If you think you know what exactly empty space is, you got to see a doctor. Read links you provided, LEARN and come back with more knowledge. Please. And stop playing the wise man that knows everything that mankind has not discovered yet. Thus you make a laughing stock of yourself. Look beneath the surface of things. Look deeper than perfect vacuum(empty space). What is perfect vacuum? Nothingness? Does nothingness exist? Now post a link to the wikipedia again.Edited by Agobot, : No reason given.

Straigth from the links you provided, wise man:"Among physicists and philosophers there is disagreement regarding whether space is itself an entity, or is part of a conceptual framework.[5]"
